Smart contract security remains one of the most critical priorities in blockchain development. With over $2.2 billion stolen from crypto platforms in 2024—a 20% increase from the previous year—the importance of thorough smart contract auditing cannot be overstated. As decentralized applications control billions of dollars in assets, a single vulnerability can lead to devastating financial losses and irreparable damage to project credibility. This comprehensive guide explores the essential tools used to audit smart contracts in 2025, the methodologies behind effective security reviews, and why platforms like Token Metrics incorporate smart contract analysis into their comprehensive crypto analytics to protect investors from risky projects.

Understanding Smart Contract Audits

A smart contract audit involves detailed analysis of a protocol's code to identify security vulnerabilities, poor coding practices, and inefficient implementations before providing solutions to resolve these issues. During an audit, security experts review the code, logic, architecture, and security measures using both automated tools and manual processes to ensure the safety, reliability, and performance of decentralized applications.

The audit process typically begins with a code freeze, where the project stops making changes and provides auditors with comprehensive technical documentation including the codebase, whitepaper, architecture diagrams, and implementation details. This documentation gives auditors a high-level understanding of what the code aims to achieve, its scope, and exact implementation strategies.

Smart contract audits typically cost between $5,000 and $15,000 for smaller projects, though complex protocols with extensive codebases can require significantly higher investments. The time to complete an audit depends on code complexity, but thorough reviews generally take several weeks to ensure all potential vulnerabilities are identified and addressed.

Static Analysis Tools: The Foundation of Smart Contract Security

Static analysis tools examine smart contract code without executing it, identifying vulnerabilities through pattern matching, data flow analysis, and abstract interpretation. These tools form the foundation of any comprehensive audit strategy.

Slither: The Industry Standard

Slither stands as one of the most powerful open-source static analysis tools for Solidity and Vyper smart contracts. Developed by Trail of Bits, Slither scrutinizes code to detect known vulnerabilities including reentrancy attacks, boolean equality issues, unused return values, and dangerous delegatecall operations.

The tool comes equipped with 92 built-in detectors and allows users to create custom detectors tailored to specific vulnerabilities of interest. This flexibility makes Slither particularly valuable for auditors who need to focus on project-specific security concerns. Additionally, Slither generates inheritance graphs and call graphs that map interactions between different functions within contracts, providing deeper insight into operational flow and system architecture.

Slither's fast execution speed enables rapid initial scans of codebases, making it ideal for continuous integration workflows where developers want immediate feedback on security issues. However, Slither is limited to Solidity and Vyper contracts, meaning projects using other smart contract languages need alternative tools.

Mythril and MythX: Comprehensive Security Analysis

Mythril is a security analysis tool for EVM bytecode that employs symbolic execution, SMT solving, and taint analysis to detect various security vulnerabilities. The tool can analyze deployed contracts by examining their bytecode directly, making it valuable for assessing contracts where source code may not be available.

MythX represents the commercial, enhanced version of Mythril, offering a more user-friendly interface and comprehensive analysis combining static analysis, dynamic analysis, and symbolic execution. The platform generates detailed reports accessible through its website, providing clear actionable insights for developers and auditors. However, MythX is a paid service with limited customization compared to open-source alternatives, and users cannot write their own detectors.

Aderyn: Modern Rust-Based Analysis

Aderyn represents the newer generation of static analysis tools, built with Rust for superior performance and accuracy. This AST (Abstract Syntax Tree) analyzer automatically examines Solidity codebases and identifies vulnerabilities in an easy-to-digest markdown format, making results accessible even for developers without deep security expertise.

Aderyn offers fast detection with low false-positive rates and integrates seamlessly into CI/CD pipelines, enabling automated security checks with every code commit. The tool allows for custom analyzer development, making it particularly useful for projects with unique security requirements or domain-specific vulnerabilities.

Dynamic Analysis and Fuzzing: Testing Under Pressure

While static analysis examines code structure, dynamic analysis and fuzzing test smart contracts under actual execution conditions, discovering vulnerabilities that only appear during runtime.

Echidna: Property-Based Fuzzing Pioneer

Echidna, developed by Trail of Bits, uses property-based fuzzing to discover vulnerabilities by testing contracts against user-defined predicates. Rather than testing specific scenarios, Echidna generates random inputs to challenge smart contracts with unexpected data, ensuring they behave as intended under various conditions.

Developers define specific properties or assertions the smart contract should uphold, enabling Echidna to target testing efforts precisely and uncover vulnerabilities related to these properties. This approach is particularly effective for discovering edge cases that manual testing might miss, such as integer overflows, unexpected state transitions, or authorization bypasses under specific conditions.

Echidna's flexibility and comprehensive toolset make it ideal for developers seeking to break even the most difficult assertions before deployment. The tool has identified critical vulnerabilities in major protocols that passed initial audits, demonstrating the value of thorough fuzzing in the security toolkit.

Medusa: Parallelized Fuzzing Power

Medusa represents an experimental evolution of Echidna, offering parallelized fuzz testing across multiple threads for dramatically improved performance. This cross-platform, go-ethereum-based smart contract fuzzer enables developers to implement custom, user-defined testing methods through both CLI and Go API interfaces.

Medusa supports assertion and property testing with built-in capabilities for writing Solidity test cases. The tool's parallel execution across multiple workers significantly reduces testing time while increasing coverage, making it suitable for large, complex protocols where comprehensive fuzzing might otherwise be impractical. Coverage-guided fuzzing helps Medusa achieve deeper analysis by focusing on code paths that haven't been adequately tested.

Foundry: Comprehensive Development Framework

Foundry has emerged as a complete smart contract development and auditing framework that combines multiple testing approaches into a unified toolkit. The framework includes Forge for testing and fuzzing, Cast for contract interactions, Anvil as a local Ethereum node, and Chisel for Solidity REPL testing.

Foundry's integrated approach enables developers to write tests in Solidity itself rather than JavaScript or other languages, reducing context switching and making tests more natural for smart contract developers. The framework supports multi-blockchain projects and enables fast integration with different networks, providing flexibility for cross-chain applications.

Formal Verification: Mathematical Proof of Correctness

Formal verification tools use mathematical techniques to prove that smart contracts behave correctly under all possible conditions, providing the highest assurance level available.

Halmos: Symbolic Execution from a16z

Halmos, developed by a16z, represents an open-source formal verification tool employing bounded symbolic execution to analyze contract logic. Unlike testing that checks specific scenarios, symbolic execution explores all possible execution paths within defined bounds, mathematically proving correctness or identifying counterexamples where the contract fails.

The tool avoids the halting problem through bounded execution, making verification computationally tractable while still providing strong security guarantees. Halmos is designed specifically for formal verification workflows, making it valuable for high-stakes protocols where mathematical certainty is required.

Scribble: Specification Language for Runtime Verification

Scribble translates high-level specifications into Solidity code, enabling runtime verification of smart contracts. Developers write specifications describing how contracts should behave, and Scribble generates assertion code that verifies these properties during execution.

This approach bridges formal verification and practical testing, allowing developers to express security properties in natural language-like syntax that Scribble converts to executable checks. Integration with other tools like Diligence Fuzzing creates powerful workflows where specifications guide automated security testing.

Cloud-Based and Enterprise Solutions

Professional audit firms offer comprehensive cloud-based platforms that combine multiple analysis techniques with expert manual review.

ConsenSys Diligence: Enterprise-Grade Security

ConsenSys Diligence provides industry-leading smart contract auditing services combining automated analysis tools with hands-on review from veteran auditors. Their platform offers APIs for affordable smart contract security options integrated directly into development environments, enabling continuous security analysis throughout the development lifecycle.

Diligence Fuzzing, powered by Harvey (a bytecode-level fuzzer), provides cloud-based automated testing with integration to Foundry and Scribble. The service identifies vulnerabilities through comprehensive fuzzing campaigns that would be impractical to run locally, providing detailed reports on potential issues.

ConsenSys Diligence has completed audits for major protocols including 0x, Keep Network, and Horizon Games, establishing themselves as trusted partners for enterprise blockchain projects requiring the highest security standards.

Cyfrin and QuillAudits: Modern Audit Services

Cyfrin and QuillAudits represent next-generation audit firms leveraging cutting-edge tools and methodologies. QuillAudits has completed over 1,400 audits across Ethereum, Polygon, Solana, Arbitrum, BSC, and other chains, securing over $3 billion in assets.

These firms combine automated tool suites with expert manual review, providing comprehensive security assessments that cover not just code vulnerabilities but also economic attack vectors, governance risks, and architectural weaknesses that purely automated tools might miss.

Specialized Tools for Comprehensive Analysis

Tenderly: Real-Time Transaction Simulation

Tenderly enables realistic transaction simulation and debugging in real-time, making it ideal for DeFi projects where understanding complex transaction flows is critical. The platform allows developers to simulate transactions before execution, identifying potential failures, unexpected behavior, or security issues in a safe environment.

Token Metrics' integrated trading platform (launched March 2025) incorporates security scores directly into the trading interface. Users can see at a glance whether tokens they're considering have passed reputable audits, enabling informed decisions that balance opportunity against risk. This integration ensures security considerations remain front-of-mind during trade execution rather than being afterthoughts.

Best Practices for Smart Contract Security in 2025

Effective smart contract security in 2025 requires multi-layered approaches combining multiple tools and methodologies. Start security testing early in development rather than treating audits as a pre-launch formality. Integrate automated tools into CI/CD pipelines for continuous security monitoring throughout the development process.

Use complementary tools rather than relying on single solutions. Combine static analysis (Slither), dynamic testing (Echidna/Medusa), formal verification (Halmos), and manual review for comprehensive coverage. No single tool catches all vulnerability types, so layered approaches significantly improve security.

Engage professional audit firms for final reviews before mainnet deployment. While automated tools catch many issues, experienced auditors identify complex vulnerabilities, economic attack vectors, and architectural weaknesses that require human expertise and creativity to discover.

Conclusion

Smart contract security tools have evolved dramatically, offering developers and auditors powerful capabilities for identifying vulnerabilities before deployment. From static analysis tools like Slither and Aderyn to dynamic fuzzing with Echidna and Medusa, formal verification with Halmos, and enterprise platforms from ConsenSys Diligence and Cyfrin, the security toolkit available in 2025 provides comprehensive coverage for protecting decentralized applications.

What Are NFTs and Why Are They Valuable? Complete 2025 Guide

Token Metrics Team
11

Non-fungible tokens, commonly known as NFTs (NFT stands for Non-Fungible Token), have evolved from a niche curiosity into a massive market that is revolutionizing digital ownership, art, gaming, and entertainment. The idea behind NFTs is to create digital tokens that represent ownership and are secured through blockchain technology, establishing unique, verifiable digital assets that can range from art to ownership rights. As the global NFT market reached an impressive $48.74 billion in 2025 and is projected to explode to $703.47 billion by 2034, understanding what are NFTs and why are they valuable has become essential knowledge for investors, creators, and anyone interested in the future of the digital economy.

Understanding Non-Fungible Tokens

A non-fungible token (NFT) is a unique digital asset stored on a blockchain that represents ownership or proof of authenticity for a specific item, whether digital or physical. The term “non-fungible” distinguishes these tokens from cryptocurrencies like Bitcoin or Ethereum, which are fungible—meaning each unit is identical and interchangeable with another. In contrast, an NFT is one of a kind and cannot be directly exchanged on a like-for-like basis.

To better grasp fungibility, consider that a dollar bill is fungible because any dollar can replace another with identical value. A fungible asset, such as money or cryptocurrency, can be exchanged interchangeably without any loss of value, while non-fungible assets—like NFTs or concert tickets—are unique and not interchangeable. However, a famous painting, such as the Mona Lisa, is non-fungible because it is unique and cannot be replaced by another painting, even by the same artist. NFTs bring this concept of unique, verifiable ownership to the digital realm through blockchain technology.

NFTs are stored on a blockchain, which ensures the authenticity and provenance of each asset. Here’s how NFTs work: the process begins with minting, where a digital file is turned into an NFT on the blockchain. Blockchain validation and smart contracts are used to confirm ownership, manage transfers, and enforce royalties, making each NFT a secure and verifiable digital certificate.

When you purchase an NFT, you acquire a digital certificate of ownership recorded on a blockchain—typically Ethereum, although other blockchain networks like Solana, Polygon, and Binance Smart Chain also host NFTs. The Ethereum Request for Comments (ERC-721) standard defines how NFT ownership is transferred and transactions are confirmed on the Ethereum blockchain. This blockchain record provides immutable proof that you own a specific digital asset, even though copies of the underlying digital file may exist elsewhere. The blockchain acts as a permanent and transparent digital ledger showing ownership history and transaction records, making these unique digital assets verifiable and secure. Each NFT is assigned a unique identifier, which distinguishes it from all other tokens and allows for precise tracking and management of ownership.

When you purchase an NFT, you are acquiring digital tokens that serve as certificates of ownership for digital or physical assets, enabling decentralized copyright and licensing scenarios.

The Core Components of NFT Value

Understanding why NFTs hold value requires examining several fundamental factors that distinguish them from simple digital files.

First and foremost is provenance and authenticity. Before NFTs, digital art and collectibles faced a fundamental problem: perfect copies were indistinguishable from originals. NFTs solve this by providing verifiable proof of authenticity through blockchain records, which securely store ownership information on the blockchain. NFTs have had a significant impact on the art world, enabling artists and collectors to monetize digital art, establish ownership, and navigate intellectual property rights in the context of digital assets and collectibles. For example, when artist Beeple sold his digital artwork “Everydays: The First 5000 Days” at Christie’s auction house for $69 million in 2021, buyers weren’t just purchasing an image file—they were acquiring authenticated ownership of a historically significant artwork with documented provenance.

Another key factor is scarcity and uniqueness. While anyone can screenshot or download a digital image, only one person or entity can own the verified NFT that represents that asset. An NFT represents a unique digital item or ownership claim, serving as a digital certificate of authenticity. Many NFT collections intentionally limit supply—the Bored Ape Yacht Club, for instance, consists of exactly 10,000 unique digital apes, with scarcity enforced through smart contracts. This artificial scarcity, combined with demand, creates market value similar to limited edition physical collectibles. While the images associated with NFTs, such as CryptoPunks, EtherRocks, and Bored Apes, are often publicly accessible and easily copied, the NFT is what confers verified ownership and authenticity.

Ownership rights and utility extend value beyond mere bragging rights. Some NFTs grant holders intellectual property rights to the underlying asset, allowing commercial use of the digital content. Others provide access to exclusive communities, events, or services. In gaming, NFTs might represent in-game items, characters, or virtual real estate that provide utility within virtual worlds. These practical applications create tangible value beyond speculation.

An innovative feature of NFTs is creator royalties built into NFT smart contracts, which ensure artists receive a percentage of secondary sales automatically. This revolutionary mechanism allows creators to participate in the ongoing appreciation of their work—something impossible in traditional art markets where artists typically profit only from initial sales.

Major NFT Categories and Use Cases

The NFT ecosystem spans diverse applications, each creating value in different ways. Here are some examples of NFT categories, such as digital art, gaming assets, and collectibles.

  • Digital art: remains the most visible NFT category, with the art segment accounting for $11.16 billion in sales and dominating market share. NFTs democratize art ownership by enabling fractional ownership and creating liquid markets for digital artworks. Artists can reach global audiences without traditional gallery gatekeepers, while collectors can display their digital artwork in virtual galleries or through digital frames. Notable NFT collections, such as Bored Ape Yacht Club, have become highly sought after by collectors due to their exclusivity, community benefits, and potential for appreciation.
  • Gaming and metaverse assets: represent one of the fastest-growing NFT categories. Play-to-earn games like Axie Infinity, Decentraland, and The Sandbox use NFTs to represent in-game items, characters, virtual land, and accessories that players truly own and can trade on open markets. This gaming integration allows players to monetize their time and skill, earning real value from gameplay. The concept of digital ownership within virtual worlds has revolutionized gaming by enabling players to build wealth through gaming activities.
  • Collectibles: mirror traditional collecting behavior in digital form. NBA Top Shot offers NFT “moments”—video highlights of basketball plays—that fans collect and trade. Virtual trading cards, digital memorabilia, and limited edition collectibles attract enthusiasts who value rarity and cultural significance. These digital collectibles often appreciate based on their historical importance, rarity, and the reputation of associated brands or athletes.
  • Music and entertainment: NFTs enable artists to sell unique recordings, concert tickets, backstage passes, and exclusive content directly to fans. Musicians can tokenize albums or individual songs, creating new revenue streams and deeper fan engagement. Tokenized concert tickets combat counterfeiting while potentially generating ongoing royalties as tickets trade in secondary markets.
  • Virtual real estate: in metaverse platforms like Decentraland and The Sandbox has sold for multi-million dollar sums, with some virtual land parcels fetching prices comparable to physical real estate. Owners can develop virtual land, host events, create experiences, or lease space to others. As virtual worlds gain users and cultural relevance, prime locations increase in value, mirroring physical real estate dynamics.

Creating and Building NFTs

Creating and building NFTs is where the worlds of digital art, technology, and innovation intersect. At its core, the process begins with an artist or creator designing a unique digital asset—this could be a digital painting, a video clip, or any form of digital artwork. What sets NFTs apart is that these digital assets are transformed into unique digital assets through blockchain technology.

To create an NFT, the artist uses a blockchain network—most commonly Ethereum—to mint a non fungible token. This process involves writing a smart contract that defines the NFT’s unique properties and links it to the specific digital asset. The NFT is then stored on a digital ledger, ensuring that the ownership and authenticity of the digital artwork are verifiable and tamper-proof.

For example, an artist might create a one of a kind digital painting and use a platform like OpenSea or Rarible to mint an NFT that represents ownership of that artwork. Once minted, the NFT can be sold to a collector, who then stores the token in their digital wallet. The blockchain record proves ownership and tracks the NFT’s history, making it easy to verify that the digital asset is authentic and unique.

This process of creating NFTs has opened up new opportunities for artists and creators, allowing them to monetize their work in the digital world and reach global audiences. Whether it’s a digital painting, a collectible video clip, or another form of digital content, NFTs provide a new form of ownership and value for digital assets.

Buying and Selling NFTs

The NFT market has become increasingly popular, with a wide array of platforms and marketplaces dedicated to buying and selling these unique digital assets. Collectors looking to purchase NFTs can explore marketplaces such as OpenSea, Rarible, and others, where digital trading cards, digital artwork, and other digital assets are listed by artists and creators from around the world.

To buy an NFT, a collector browses the marketplace, selects a unique digital asset—such as a digital trading card or a piece of digital art—and completes the purchase using cryptocurrency like Ethereum or Bitcoin. After the transaction, the NFT is transferred to the buyer’s digital wallet, ready for display or future trade.

Selling NFTs follows a similar process. Artists and creators can list their digital assets on NFT marketplaces, set prices, and reach a broad audience. The marketplace handles the transaction, ensuring proper transfer and recording on the blockchain.

NFTs in Real Life

NFTs are making an impact beyond the digital environment, bridging digital and physical assets. They can represent ownership of real estate, artwork, or luxury items. By storing ownership records on a blockchain, NFTs simplify buying, selling, and transferring physical assets securely and transparently.

For instance, a real estate developer might create an NFT representing ownership of a property. When sold, the new owner's rights are recorded on the blockchain, streamlining the transfer process. Artists can also use NFTs to represent physical artworks, like paintings or sculptures, providing verifiable proof of authenticity.

NFTs enable new business models, such as tokenized services, exclusive experiences, or digital tickets, linking the virtual with the tangible world. These applications are transforming how ownership and value are perceived both digitally and physically.

Why NFTs Hold Market Value

The rapid growth of NFTs—projected to reach over $700 billion by 2034—reflects several core drivers of value:

  • Digital Ownership Paradigm: NFTs establish a new form of digital property, allowing true ownership, transfer, and security, especially appealing to digital-native generations.
  • Social Signaling: Owning rare or prestigious NFTs acts as a status symbol within communities, with high-profile sales demonstrating their monetary and cultural significance.
  • Investment & Speculation: NFTs can appreciate in value, attracting investors seeking returns and creating markets for trading and portfolio diversification.
  • Brand Engagement: Companies leverage NFTs for marketing, loyalty programs, and exclusive commerce, enhancing brand loyalty and customer interaction.

As the NFT ecosystem evolves, data-driven analysis becomes essential for identifying valuable projects and avoiding scams. Token Metrics offers extensive NFT market analytics—tracking trading volumes, price trends, project fundamentals, and holder distribution across major platforms. Using AI-powered scoring, it helps distinguish promising projects from short-term hype, providing insights into team credibility, community strength, utility, and market momentum.

Market participants benefit from real-time alerts, facilitating timely decisions around price movements, major industry announcements, or project developments. Additionally, Token Metrics enables understanding of correlations between NFTs and broader crypto markets, such as ETH price influences, giving a holistic view for strategic positioning.

Security and Safety in the NFT Space

Security measures like multi-factor authentication, encryption, and regular audits protect user accounts and transaction integrity. Artists and collectors should also use practices like watermarks, rights management, and reputable platforms to minimize risks of theft, fraud, or counterfeit. Vigilance, research, and choosing trustworthy marketplaces are key to a safer NFT environment.

Challenges and Considerations

NFTs face hurdles such as high energy consumption on proof-of-work blockchains, regulatory uncertainties, market volatility, and scams involving fake projects or wash trading. Sustainability efforts and evolving legal frameworks aim to address these issues, but participants must exercise caution and perform due diligence to navigate this complex landscape effectively.

The Future of Digital Ownership

NFTs underpin a shift towards broader digital and physical asset tokenization, enabling use cases like fractional ownership, collateralization, and integration into the metaverse. As technology and regulation advance, NFTs are poised to become an integral part of digital commerce, legal systems, and daily life.

Conclusion

NFTs establish verifiable ownership, scarcity, and transferability for digital assets through blockchain technology. Their value arises from provenance, limited supply, utility, social signaling, and investment potential. With the market projected to grow significantly, understanding NFTs is essential for engaging with the evolving digital landscape. Navigating this space effectively requires robust data, market analysis tools, and strategic insight, which platforms like Token Metrics can provide to support informed decision-making in digital asset management.

Building the On-Chain S&P 500: A Technical Deep Dive into TM100 | Crypto Indices

Token Metrics Team
10

Welcome to a deep dive into the evolution of crypto portfolio management and how innovative on-chain indices are shaping the future of digital asset strategies. As the crypto landscape matures, new methodologies emerge to address longstanding challenges and unlock new opportunities for investors and developers alike.

The Evolution of Crypto Portfolio Management

We've been working toward this launch for several years, through multiple pivots and market cycles. What started as a centralized exchange concept evolved into a fully on-chain solution as we observed the market's clear trajectory toward decentralized infrastructure. The TM100 index represents our most significant product development to date: a non-custodial, cross-chain crypto index with integrated risk management.

The crypto market has matured considerably since 2017. We've collectively experienced the pattern: massive rallies followed by 70-95% drawdowns, the challenge of maintaining discipline during euphoria, and the difficulty of executing systematic strategies when emotions run high. This cycle presents unique characteristics—it's become intensely narrative-driven and trading-focused, with leadership rotating weekly rather than quarterly.

The Core Problem

Traditional crypto portfolio management faces several structural challenges:

Technical Architecture

Multi-Chain Infrastructure

The TM100 operates across seven blockchains: Ethereum, Base, Binance Smart Chain, Polygon, Avalanche, Arbitrum, and Solana. This represents six EVM-compatible chains plus Solana, covering the vast majority of liquid crypto assets.

We use wrapped derivatives (WBTC instead of BTC, WETH instead of ETH) to standardize operations across EVM chains. All funds are held in a master vault on Base (selected for lower transaction costs), with sub-vaults on other chains holding underlying assets.

Selection Methodology

The index tracks the top 100 tokens by market capitalization, filtered through two critical criteria:

Market cap weighting determines position sizing, with weekly rebalancing to capture narrative shifts. Our backtesting suggests 5-15% portfolio turnover weekly to monthly, depending on market conditions.

The Risk Management Layer

This is where the product differentiates from passive indices. We've integrated our market indicator to create a risk-off mechanism:

The system doesn't try to catch falling knives. When the market indicator flips bearish, the index systematically exits. This addresses what we consider the primary challenge in crypto: not missing the rally, but avoiding the round trip.

Smart Contract Standards

We're using ERC-4626, Ethereum's tokenized vault standard. This provides:

The delegated actions feature (ERC-7682) allows automated rebalancing while maintaining non-custodial status. Users grant permission for the vault to rebalance but retain ultimate control and withdrawal rights.

Security Infrastructure

Given the target scale (we're planning for significant AUM), security requires multiple layers:

DeFi Composability: The Real Innovation

The index token itself becomes a tradable, yield-bearing, composable asset. This creates possibilities beyond traditional index funds:

Primary Markets

API Access

We're integrating TM100 into our developer API. AI agents built on Virtual Protocol or Eliza can programmatically invest in the index. During our European hackathon, treasury management emerged as the most popular use case.

This composability creates network effects. As TVL grows, more DeFi protocols integrate the token, attracting more capital, which enables further integrations—a sustainable flywheel.

Performance Analysis

Disclaimer: All results are backtested simulations, not live trading results.

Testing from 2017 to present:

The maximum drawdown metric deserves emphasis. Bitcoin historically shows approximately 75% peak-to-trough drawdowns. A 41% maximum drawdown represents significant downside protection while maintaining similar Sharpe ratios to Bitcoin (around 1.5 for BTC this cycle).

Across cycles, Bitcoin's maximum drawdown tends to decrease by about 10% each cycle: from roughly 95% two cycles ago, to around 85% last cycle, and an estimated 75% in this cycle. The asset is maturing, attracting institutional capital with lower volatility tolerance. Altcoins generally lag Bitcoin by one cycle in this pattern, with Ethereum’s drawdown characteristics mirroring Bitcoin's from a prior cycle.

Fee Structure and Economics

Management Fee: 1% annually, accruing on-chain (likely daily). Performance Fee: 15% quarterly, with a high watermark. This means fees are only charged on new profits. If the index increases then falls, no fees are due until it surpasses its previous peak.

For context, our Token Metrics Ventures fund charges 2% management and 20% performance. The index’s lower fees are due to operational efficiencies once smart contracts are deployed.

TMAI Integration

Our native token reduces fees through staking scores:

This setup aligns incentives: users who stake and participate benefit from fee discounts and revenue sharing.

Liquidity and Execution

Phase 1 (Current): LI.FI integration for smart order routing. Handles trades up to around $25,000 efficiently with minimal slippage.

Phase 2 (Q4 target): Market maker integrations (Wintermute, Amber) for larger orders via request-for-quote. Orders between $25,000 and $250,000 will compare on-chain quotes against market maker quotes for optimal execution.

Phase 3 (Planned): Full API access for programmatic trading and platform integration. Current methods pool capital over 24 hours to optimize gas and price impact; future iterations will execute more granular trades staggered throughout the day.

Market Context and Timing

We project a cycle peak around spring to fall 2026, roughly one year from now. Our key targets include:

This cycle is characterized by intense trading activity, with perpetual platforms like Hyperliquid, Bybit, and Binance dominating volume. Narrative rotation occurs weekly, and every major exchange is launching on-chain alternatives, reflecting shifting liquidity flows.

Our strategic focus has shifted from new venture investments to liquid strategies, given the challenges posed by high-FDV launches and retail behavior. Regulatory developments and stablecoin adoption are accelerating tokenization and traditional asset integrations.

As a cyclical asset class, crypto's resilience depends on timing accurately. If the cycle extends beyond 2026, the index remains deployed; if the market turns bearish, the system withdraws to preserve capital. This adaptive approach aims to leverage both uptrends and downturns.

Implementation Details

The early access process involves:

The platform provides:

Once received, index tokens are immediately tradable and composable, supporting a variety of DeFi strategies.

Beyond TM100: Future Considerations

While initial plans included multiple sector-specific indices (AI, memes, DeFi), liquidity fragmentation and lower-than-expected volume have shifted focus to a single, highly liquid index. Benefits of this approach include:

Future concepts include:

Why This Matters

The crypto market has long sought robust, on-chain infrastructure to address retail and institutional needs. Challenges include concentrated bets, custody risks, and high fees. Many high-profile failures underscored the importance of transparency, automation, and non-custodial design.

The Token Metrics TM100 aims to provide a systematic, transparent, and secure solution for diversified exposure, harnessing DeFi’s composability and automation to support a mature market infrastructure.

Technical Roadmap

Current (Early Access):

Q4 2024:

Q1 2025:

Beyond 2025:

Conclusion

Building on-chain infrastructure involves unique tradeoffs: immutability, gas costs, and layered security. By approaching TM100 as foundational infrastructure, we aim to provide a primitive that supports innovation and institutional adoption alike. As crypto matures, this decentralized, secure, and composable approach enables new sophistication in digital asset management.

The code is entering final audits. Early access onboarding begins soon. The foundational infrastructure is ready to serve the evolving demands of the crypto ecosystem.

The Self-Custodial Crypto Index: Why You Don't Need to Trust Us With Your Crypto

Token Metrics Team

"Not your keys, not your crypto" has become the defining mantra of crypto's sovereignty movement. Yet most crypto indices require exactly what the industry warns against: trusting a third party with custody of your assets. You deposit funds into their platform, they promise to manage it responsibly, and you hope they're not the next FTX, Celsius, or BlockFi.Token Metrics built TM Global 100 on a radically different principle: you shouldn't need to trust us. The index operates through self-custodial embedded wallets where you maintain complete control of your funds. Token Metrics cannot access your crypto, cannot freeze your account, cannot require permission to withdraw, and cannot misuse your capital—not because we promise not to, but because the architecture makes it impossible.

This isn't marketing language. It's verifiable through on-chain examination of the smart contract wallet system. Understanding why this matters requires reviewing crypto's history of custodial failures—and understanding how Token Metrics' approach eliminates these risks entirely while maintaining sophisticated index functionality.

The Custodial Crisis: When "Trust Us" Fails

Crypto's short history is littered with custodial disasters. Each promised security, each broke that promise, and each reinforced why self-custody matters.

The Hall of Shame: Major Custodial Failures

  • Mt. Gox (2014): Once handled 70% of all Bitcoin transactions. Declared bankruptcy after losing 850,000 BTC (~$450M at the time). Users had no recourse—funds simply vanished. Lesson: Size and market dominance don't guarantee security.
  • QuadrigaCX (2019): Canadian exchange collapsed after founder's death. $190M in customer funds inaccessible. Revealed funds had been misappropriated for years. Lesson: Single points of failure create catastrophic risk.
  • Celsius Network (2022): Promised 18%+ yields on deposits. Filed bankruptcy owing $4.7B to users. Revealed massive mismanagement and risky lending. Users waited years for partial recovery. Lesson: High yields often mask unsustainable business models.
  • FTX (2022): Third-largest exchange by volume. Collapsed in 72 hours after revealing $8B hole in balance sheet. Customer deposits illegally used for proprietary trading. Criminal charges against leadership. Lesson: Even "reputable" custodians can commit fraud.
  • BlockFi (2022): Lending platform with 650,000+ users. Bankruptcy following exposure to FTX and Three Arrows Capital. Users became unsecured creditors. Lesson: Custodial services create contagion risk across platforms.

The Common Pattern

  1. Trust establishment: Platform builds reputation through marketing, partnerships, and perceived legitimacy.
  2. Deposit accumulation: Users transfer custody of assets based on trust.
  3. Mismanagement/fraud: Platform misuses funds through incompetence or malice.
  4. Crisis discovery: Problem becomes public, often suddenly.
  5. Withdrawal freeze: Platform blocks user access to protect remaining assets.
  6. Bankruptcy: Legal proceedings that recover pennies on the dollar.

Token Metrics analyzed 23 major crypto custodial failures from 2014-2024. Average customer recovery: 31 cents per dollar. Average recovery timeline: 2.7 years. Percentage of cases with criminal charges: 39%. The data is clear: custodial risk isn't theoretical. It's the largest predictable loss vector in crypto investing.

What Self-Custody Actually Means

Self-custody means you—and only you—control the private keys that authorize transactions from your wallet. No intermediary can access, freeze, seize, or require approval to move your funds.

The Key Principles

  • Principle 1: Exclusive Control Traditional custody: Provider holds private keys. You request withdrawals. They approve or deny. Self-custody: You hold private keys (or control smart contract wallet). You authorize transactions. No third-party approval required.
  • Principle 2: On-Chain Verification Custodial balances: Provider's database says you own X tokens. You trust their accounting. Self-custodial balances: Blockchain shows your wallet address owns X tokens. Publicly verifiable, tamper-proof.
  • Principle 3: Counterparty Independence Custodial services: If provider goes bankrupt, your funds are trapped in legal proceedings. Self-custody: If a service provider disappears, your funds remain accessible in your wallet.
  • Principle 4: Censorship Resistance Custodians: Can freeze accounts, block transactions, or seize funds based on their policies or government requests. Self-custody: No entity can prevent you from transacting (subject only to blockchain protocol rules).

The Traditional Self-Custody Tradeoffs

Pure self-custody (hardware wallets, MetaMask, etc.) provides maximum security but historically came with significant operational burden:

  • Complex setup processes (seed phrases, hardware wallets)
  • Manual transaction signing for every action
  • No recovery if seed phrase is lost
  • Technical knowledge requirements
  • Limited functionality (no automated strategies)

These tradeoffs meant most users chose custodial services for convenience—accepting counterparty risk for operational simplicity. Token Metrics' embedded wallet architecture eliminates this false choice.

Token Metrics' Self-Custodial Architecture

TM Global 100 uses embedded smart contract wallets that provide self-custody without traditional complexity. Here's how it works:

Smart Contract Wallets Explained

Traditional crypto wallets are "externally owned accounts" (EOAs)—addresses controlled by a single private key. Lose that key, lose the funds. Smart contract wallets are programmable accounts with built-in security features and recovery mechanisms.

  • Multi-Factor Authentication: Instead of a single private key, wallet access uses email verification, biometrics, or social login. The cryptographic keys are sharded across multiple secure enclaves—no single point of compromise.
  • Social Recovery: If you lose access (lost phone, forgotten password), designated guardians or recovery mechanisms restore access without needing a 12-word seed phrase stored on paper.
  • Programmable Security: Set spending limits, require multi-signature for large transactions, whitelist addresses, or implement time-locks. Security policies impossible with traditional wallets.
  • Account Abstraction: Gas fee management, transaction batching, and network switching happen automatically. Users see simple dollar amounts and confirmations, not hexadecimal addresses.

Who Controls What

  • You Control: Wallet access (through your authentication), transaction authorization (all buys/sells require your approval), fund withdrawals (move to any address, anytime), recovery mechanisms (designate guardians if desired).
  • Token Metrics Controls: Index strategy (what TM Global 100 holds), rebalancing execution (when signals say to rebalance), smart contract development (code underlying the system).

Token Metrics CANNOT:

  • Access your wallet without your authentication
  • Withdraw your funds to any address
  • Freeze your account or block transactions
  • Require approval to move your assets
  • Seize funds under any circumstances

This separation is enforced by smart contract architecture, not trust. The code determines what's possible—and accessing user funds isn't possible, even if Token Metrics wanted to.

On-Chain Verification

Every TM Global 100 wallet is a publicly visible blockchain address. Using blockchain explorers (Etherscan, etc.), anyone can verify:

  • Wallet balance matches what the interface shows
  • Transaction history matches logged rebalances
  • Funds are actually in user-controlled wallet, not Token Metrics' custody
  • Smart contract permissions don't allow Token Metrics withdrawal authority

This transparency means trust becomes optional—you verify rather than trust.

The Practical Reality: How Self-Custody Works Daily

Token Metrics designed TM Global 100's self-custodial experience to be invisible to users while maintaining full sovereignty.

Initial Setup (90 seconds)

  • Navigate to TM Global 100 on Token Metrics Indices hub
  • Click "Buy Index"
  • Create embedded wallet: Provide email or use social login (Google, Apple)
  • Set authentication: Biometrics or password
  • Fund wallet: Transfer crypto or use on-ramp to purchase
  • Confirm purchase: Review TM Global 100 details and approve

Your wallet is created, you control it, and you've bought the index—all while maintaining self-custody.

Ongoing Operations (Zero Custody Risk)

Weekly Rebalances: Token Metrics' smart contract initiates rebalance based on strategy rules. Transaction occurs within YOUR wallet (not custodial account). You can see the transaction on blockchain explorers. Funds never leave your control—they just recompose from BTC+ETH+... to updated weights.

Regime Switches: When signals turn bearish, YOUR wallet sells crypto and holds stables. When signals turn bullish, YOUR wallet buys crypto from stables. Token Metrics triggers the transaction, but it executes in your self-custodial wallet.

Withdrawals: At any time, withdraw some or all funds to any address. No approval needed from Token Metrics. It’s a standard blockchain transaction—Token Metrics can't block it.

What Happens If Token Metrics Disappears?

Imagine Token Metrics goes bankrupt tomorrow. With custodial services, your funds are trapped. With TM Global 100:

  • Your wallet still exists (it's on-chain, independent of Token Metrics)
  • Your holdings remain accessible (you can view balances on blockchain explorers)
  • You can transfer funds (to any wallet/exchange you choose)
  • You can continue holding (the tokens don't disappear)
  • You can't access automated rebalancing (that requires Token Metrics' smart contracts), but your capital is 100% safe and accessible.

This is the power of self-custody: no dependency on the service provider's solvency or operations.

Comparison to Custodial Crypto Indices

Token Metrics isn't the only crypto index provider. How does TM Global 100's self-custody compare to alternatives?

Custodial Index Providers

  • Typical Structure: Deposit funds to provider's platform. Provider holds crypto in their custody. You own "shares" or "units" representing claim on assets. Withdrawal requires provider approval and processing time.
  • Advantages: Familiar model for traditional finance users, May offer insurance (though rarely covers full balances), Simple tax reporting through provider.
  • Disadvantages: Counterparty risk, Provider failure means lost funds, Withdrawal restrictions, Can freeze accounts, Delay withdrawals, Regulatory risk, Government can seize provider’s assets, Transparency limits, Can't verify actual holdings on-chain, Censorship vulnerability, Can block your access unilaterally.

Self-Custodial Model

Funds remain in your self-custodial smart contract wallet. You maintain control via private authentication. Token Metrics provides strategy execution, not custody. Withdrawal is immediate—it's already your wallet.

  • Advantages: Zero counterparty risk, No withdrawal restrictions, Move funds any time, Regulatory isolation, Transparent on-chain holdings, Censorship resistance.
  • Tradeoffs: User responsibility for wallet management, No traditional insurance, You handle tax reporting, Logs are provided.

For investors who understand crypto's core value—financial sovereignty—the self-custodial model is strictly superior. Custodial convenience isn't worth systemic risk.

Trustless by Design

Token Metrics established itself as the premier crypto analytics platform by providing exceptional research to 50,000+ users—building trust through performance, not promises. But with TM Global 100, Token Metrics deliberately designed a system where trust is unnecessary.

Traditional Financial Services

"Trust us to handle your money responsibly. We have reputation, insurance, and regulatory oversight."

Crypto's Original Vision

"Don't trust, verify. Use cryptographic proof and transparent blockchains to eliminate need for trust."

TM Global 100

"We provide excellent research and systematic execution. But you don't need to trust us with custody—verify your holdings on-chain, control your keys, withdraw anytime."

This philosophy aligns with crypto's foundational principles while delivering institutional-grade sophistication.

How Token Metrics Makes Money Without Custody

Traditional indices profit by holding client assets and taking fees. Token Metrics profits differently: Platform Fee: Annual percentage (1.5-2.0%) charged from YOUR holdings in YOUR wallet. No custody required to collect fees—they're automatically deducted from the smart contract wallet based on holdings value. Not Revenue Sources for TM Global 100: Lending out client funds (we don't hold them), Interest on deposited cash (there is no deposit), Proprietary trading with client capital (we can't access it), Rehypothecation (impossible without custody). Token Metrics' business model works precisely because we DON'T hold funds. The platform fee compensates for research, development, and operations—without requiring custody or creating counterparty risk.

The Accountability Structure

Self-custody creates natural accountability:

  • Custodial Model: If provider performs poorly, changing is difficult (withdrawal delays, tax events, operational friction). Users stay with mediocre services out of inertia.
  • Self-Custodial Model: If TM Global 100 underperforms expectations, users can withdraw immediately with zero friction. Token Metrics must continuously earn business through performance, not trap users through custody. This alignment of incentives produces better outcomes. Token Metrics succeeds only if TM Global 100 delivers value—not if we successfully retain custody.

Security Without Custodial Risk

Self-custody doesn't mean "no security"—it means security without counterparty risk. Token Metrics implements multiple security layers:

  • Wallet Security: Multi-Factor Authentication, Encryption, Rate Limiting, Device Fingerprinting, Session Management.
  • Smart Contract Security: Audited Code, Immutable Logic, Permission Controls, Upgrade Mechanisms.
  • Operational Security: No Centralized Custody, Separation of Duties, Monitoring Systems, Incident Response.
  • Recovery Security: Social Recovery, Time-Locked Recovery, Guardian Options, No Single Point of Failure.

This comprehensive security operates without Token Metrics ever holding custody—proving security and sovereignty aren't mutually exclusive.

The Regulatory Advantage

Self-custody provides regulatory benefits beyond security:

  • Reduced Compliance Burden: Token Metrics doesn't need custodial licenses or maintain costly compliance infrastructure for holdings we don't control.
  • Jurisdictional Flexibility: Users can access TM Global 100 based on their local regulations without Token Metrics needing approval in every jurisdiction (though we maintain appropriate licensing for our services).
  • Asset Protection: Government actions against Token Metrics don't freeze user funds—they're already in user wallets.
  • Portability: Regulatory changes in one region don't trap users—they control their funds and can move them freely.

As crypto regulations evolve globally, self-custodial models will likely face less restrictive treatment than custodial alternatives—another reason Token Metrics chose this architecture.

Decision Framework: Custodial vs. Self-Custodial Indices

  • Choose self-custodial indices (TM Global 100) if: You value financial sovereignty, censorship resistance, want on-chain verification, eliminate counterparty risk, are comfortable with wallet authentication, and desire instant withdrawal.
  • Consider custodial alternatives if: You prefer traditional finance models, want FDIC-style insurance (though limited), need institutional custody for compliance, are uncomfortable managing wallets, or prioritize traditional tax reporting.

For most crypto investors—especially those who understand why Bitcoin was created—self-custody is non-negotiable. TM Global 100 delivers sophisticated index strategies without compromising this core principle.

Conclusion: Trust Through Verification, Not Promises

The crypto industry has taught expensive lessons about custodial risk. Billions in user funds have vanished through exchange collapses, lending platform failures, and outright fraud. Each disaster reinforced crypto's founding principle: financial sovereignty requires self-custody.

Token Metrics built TM Global 100 to honor this principle. The index provides systematic diversification, weekly rebalancing, regime-based risk management, and institutional-grade execution—all while you maintain complete control of your funds. Token Metrics can't access your crypto, not because we promise not to, but because the smart contract architecture makes it impossible.

This isn't about not trusting Token Metrics. It's about not needing to trust Token Metrics—or anyone else—with custody of your capital. That's how crypto is supposed to work. You verify holdings on-chain. You control withdrawals. You authorize transactions. Token Metrics provides research, signals, and systematic execution. But your crypto stays yours.

As crypto matures, self-custodial infrastructure will become standard—not because it's idealistic, but because custodial alternatives have failed too many times, too catastrophically. Token Metrics is simply ahead of the curve. Not your keys, not your crypto. TM Global 100: your keys, your crypto.
