In today’s digital world, our identities define how we interact online—from accessing services to proving who we are. However, traditional identity management systems often place control of your personal information in the hands of centralized authorities, such as governments, corporations, or social media platforms. This centralized control exposes users to risks like data breaches, identity theft, and loss of privacy. Enter Self-Sovereign Identity (SSI), a revolutionary digital identity model aligned with the core principles of Web3: decentralization, user empowerment, and true digital ownership. Understanding what is self sovereign identity in Web3 is essential in 2025 for anyone who wants to take full control of their digital identity and navigate the decentralized future safely and securely.

Understanding Self-Sovereign Identity: The Foundation of Digital Freedom

At its core, self sovereign identity is a new digital identity model that enables individuals to own, manage, and control their identity data without relying on any central authority. Unlike traditional identity systems, where identity data is stored and controlled by centralized servers or platforms—such as social media companies or government databases—SSI empowers users to become the sole custodians of their digital identity.

The self sovereign identity model allows users to securely store their identity information, including identity documents like a driver’s license or bank account details, in a personal digital wallet app. This wallet acts as a self sovereign identity wallet, enabling users to selectively share parts of their identity information with others through verifiable credentials. These credentials are cryptographically signed by trusted issuers, making them tamper-proof and instantly verifiable by any verifier without needing to contact the issuer directly.

This approach means users have full control over their identity information, deciding exactly what data to share, with whom, and for how long. By allowing users to manage their digital identities independently, SSI eliminates the need for centralized authorities and reduces the risk of data breaches and unauthorized access to sensitive information.

The Web3 Context: Why SSI Matters Now

The emergence of Web3—a decentralized internet powered by blockchain and peer-to-peer networks—has brought new challenges and opportunities for digital identity management. Traditional login methods relying on centralized platforms like Google or Facebook often result in users surrendering control over their personal data, which is stored on centralized servers vulnerable to hacks and misuse.

In contrast, Web3 promotes decentralized identity, where users own and control their digital credentials without intermediaries. The question what is self sovereign identity in Web3 becomes especially relevant because SSI is the key to realizing this vision of a user-centric, privacy-respecting digital identity model.

By 2025, businesses and developers are urged to adopt self sovereign identity systems to thrive in the Web3 ecosystem. These systems leverage blockchain technology and decentralized networks to create a secure, transparent, and user-controlled identity infrastructure, fundamentally different from centralized identity systems and traditional identity management systems.

The Three Pillars of Self-Sovereign Identity

SSI’s robust framework is built on three essential components that work together to create a secure and decentralized identity ecosystem:

1. Blockchain Technology

Blockchain serves as a distributed database or ledger that records information in a peer-to-peer network without relying on a central database or centralized servers. This decentralized nature makes blockchain an ideal backbone for SSI, as it ensures data security, immutability, and transparency.

By storing digital identifiers and proofs on a blockchain, SSI systems can verify identity data without exposing the actual data or compromising user privacy. This eliminates the vulnerabilities associated with centralized platforms and frequent data breaches seen in traditional identity systems.

2. Decentralized Identifiers (DIDs)

A Decentralized Identifier (DID) is a new kind of globally unique digital identifier that users fully control. Unlike traditional identifiers such as usernames or email addresses, which depend on centralized authorities, DIDs are registered on decentralized networks like blockchains.

DIDs empower users with user control over their identity by enabling them to create and manage identifiers without relying on a central authority. This means users can establish secure connections and authenticate themselves directly, enhancing data privacy and reducing reliance on centralized identity providers.

3. Verifiable Credentials (VCs)

Verifiable Credentials are cryptographically secure digital documents that prove certain attributes about an individual, organization, or asset. Issued by trusted parties, these credentials can represent anything from a university diploma to a government-issued driver’s license.

VCs are designed to be tamper-proof and easily verifiable without contacting the issuer, thanks to blockchain and cryptographic signatures. This ensures enhanced security and trustworthiness in digital identity verification processes, while allowing users to share only the necessary information through selective disclosure.

How SSI Works: The Trust Triangle

The operation of SSI revolves around a trust triangle involving three key participants:

  • Holder: The individual who creates their decentralized identifier using a digital wallet and holds their digital credentials.
  • Issuer: A trusted entity authorized to issue verifiable credentials to the holder, such as a government, university, or bank.
  • Verifier: An organization or service that requests proof of identity or attributes from the holder to validate their claims.

When a verifier requests identity information, the holder uses their self sovereign identity wallet to decide which credentials to share, ensuring full control and privacy. This interaction eliminates the need for centralized intermediaries and reduces the risk of identity theft.

Token Metrics: Leading the Charge in Web3 Analytics and Security

As SSI platforms gain traction, understanding their underlying token economies and security is critical for investors and developers. Token Metrics is a leading analytics platform that provides deep insights into identity-focused projects within the Web3 ecosystem.

By analyzing identity tokens used for governance and utility in SSI systems, Token Metrics helps users evaluate project sustainability, security, and adoption potential. This is crucial given the rapid growth of the digital identity market, projected to reach over $30 billion by 2025.

Token Metrics offers comprehensive evaluations, risk assessments, and performance tracking, empowering stakeholders to make informed decisions in the evolving landscape of self sovereign identity blockchain projects.

Real-World Applications of SSI in 2025

Financial Services and DeFi

SSI streamlines Know Your Customer (KYC) processes by enabling users to reuse verifiable credentials issued by one institution across multiple services. This reduces redundancy and accelerates onboarding, while significantly lowering identity fraud, which currently costs billions annually.

Healthcare and Education

SSI enhances the authenticity and privacy of medical records, educational certificates, and professional licenses. Universities can issue digital diplomas as VCs, simplifying verification and reducing fraud.

Supply Chain and Trade

By assigning DIDs to products and issuing VCs, SSI improves product provenance and combats counterfeiting. Consumers gain verifiable assurance of ethical sourcing and authenticity.

Gaming and NFTs

SSI allows users to prove ownership of NFTs and other digital assets without exposing their entire wallet, adding a layer of privacy and security to digital asset management.

Advanced SSI Features: Privacy and Security

Selective Disclosure

SSI enables users to share only specific attributes of their credentials. For example, proving age without revealing a full birthdate helps protect sensitive personal information during verification.

Zero-Knowledge Proofs

Zero-knowledge proofs (ZKPs) allow users to prove statements about their identity without revealing the underlying data. For instance, a user can prove they are over 18 without sharing their exact birthdate, enhancing privacy and security in digital interactions.

Current SSI Implementations and Projects

Several initiatives showcase the practical adoption of SSI:

  • ID Union (Germany): A decentralized identity network involving banks and government bodies.
  • Sovrin Foundation: An open-source SSI infrastructure leveraging blockchain for verifiable credentials.
  • European Blockchain Services Infrastructure (EBSI): Supports cross-border digital diplomas and identity.
  • Finland’s MyData: Empowers citizens with control over personal data across sectors.

These projects highlight SSI’s potential to transform identity management globally.

Challenges and Considerations

Technical Challenges

Managing private keys is critical; losing a private key can mean losing access to one’s identity. Solutions like multi-signature wallets and biometric authentication are being developed to address this.

Regulatory Landscape

Global regulations, including the General Data Protection Regulation (GDPR) and emerging frameworks like Europe’s eIDAS 2.0, are shaping SSI adoption. Ensuring compliance while maintaining decentralization is a key challenge.

Adoption Barriers

Despite the promise, some critics argue the term "self-sovereign" is misleading because issuers and infrastructure still play roles. Improving user experience and educating the public are essential for widespread adoption.

The Future of SSI in Web3

By 2025, self sovereign identity systems will be vital for secure, private, and user-centric digital interactions. Key trends shaping SSI’s future include:

  • Enhanced Interoperability between blockchains and DID methods.
  • Improved User Experience through intuitive wallets and interfaces.
  • Regulatory Clarity supporting SSI frameworks.
  • Integration with AI for advanced cryptographic verification.

Implementation Guidelines for Businesses

Businesses aiming to adopt SSI should:

  • Utilize blockchain platforms like Ethereum or Hyperledger Indy that support SSI.
  • Prioritize user-friendly digital wallets to encourage adoption.
  • Ensure compliance with global data protection laws.
  • Collaborate across industries and governments to build a robust SSI ecosystem.

Conclusion: Embracing Digital Sovereignty

Self-Sovereign Identity is more than a technological innovation; it represents a fundamental shift towards digital sovereignty—where individuals truly own and control their online identities. As Web3 reshapes the internet, SSI offers a secure, private, and user-centric alternative to centralized identity systems that have long dominated the digital world.

For professionals, investors, and developers, understanding what is self sovereign identity in Web3 and leveraging platforms like Token Metrics is crucial to navigating this transformative landscape. The journey toward a decentralized, privacy-respecting digital identity model has begun, and those who embrace SSI today will lead the way in tomorrow’s equitable digital world.

Why Manual Crypto Portfolio Management Is Costing You Money (And Time)

Token Metrics Team
6
MIN

You're tracking 50+ tokens across three exchanges, updating your rebalancing spreadsheet every weekend, and second-guessing every exit decision at 2 AM. Sound familiar? Manual crypto portfolio management isn't just exhausting—it's expensive. Between missed rebalances, execution drag, and behavioral mistakes during volatility, DIY portfolio management quietly erodes returns before you see any market gains.

The data tells the story: investors who manually manage diversified crypto portfolios typically underperform comparable automated strategies by 12-18% annually, with 60% of that gap coming from operational inefficiency rather than market timing. If you're spending 10+ hours weekly maintaining positions, those hours have a cost—and it's higher than you think.

The Hidden Costs Destroying Your Returns

Time Drain: The 500-Hour Tax

Managing a diversified crypto portfolio demands constant vigilance. For investors holding 20+ positions, the weekly time investment breaks down to approximately:

  • Market monitoring: 5-8 hours tracking prices, news, and on-chain metrics
  • Rebalancing calculations: 2-3 hours determining optimal weights and required trades
  • Order execution: 3-5 hours placing trades across multiple platforms
  • Record keeping: 1-2 hours logging transactions for tax reporting
  • Research updates: 3-5 hours staying current on project developments

That's 14-23 hours weekly, or 728-1,196 hours annually. At a conservative $50/hour opportunity cost, you're spending $36,400-$59,800 in time value maintaining your portfolio. Even if you value your time at minimum wage, that's still $10,000+ in annual "sweat equity" that automated solutions eliminate.

Execution Drag: Death by a Thousand Trades

Small trades erode portfolios through accumulated friction. Every manual rebalance across a 50-token portfolio requires dozens of individual transactions, each incurring:

  • Trading fees: 0.1-0.5% per trade (average 0.25%)
  • Bid-ask spreads: 0.2-0.8% depending on liquidity
  • Slippage: 0.3-1.2% on smaller cap tokens
  • Gas fees: $2-50 per transaction depending on network congestion

For a $100,000 portfolio rebalanced monthly with 40 trades per rebalance, the costs add up:

  • Average cost per trade: ~$100
  • Monthly execution drag: $4,000
  • Annual execution drag: $48,000 (48% of portfolio value)

The smaller your individual trades, the worse the ratio becomes. A $500 rebalancing trade on a low-liquidity altcoin might pay $25 in fees—a 5% instant loss before any price movement.

Automated indices solve this. TM Global 100, Token Metrics' rules-based index, consolidates 100 individual positions into a single transaction at purchase, with weekly rebalances executed through optimized smart contract batching. Users typically save 3-7% annually in execution costs alone compared to manual approaches.

Behavioral Mistakes: Your Worst Enemy Is in the Mirror

Market psychology research shows that manual portfolio managers tend to make predictable, costly mistakes:

  • Panic selling during drawdowns: When Bitcoin drops 25% in a week, can you stick to your exit rules? Many override their plans during high volatility, often selling near local bottoms.
  • FOMO buying at peaks: Tokens up 300% in a week attract chase behavior, with managers entering after the movement is mostly over.
  • Rebalancing procrastination: Putting off rebalancing leads to drift, holding too much of past winners and missing new opportunities.

Token Metrics' systematic approach removes emotion from the equation. The TM Global 100 Index follows a transparent ruleset: hold the top 100 tokens by market cap during bullish phases, shift to stablecoins during bearish cycles, and rebalance weekly—eliminating emotional override and procrastination.

Missed Rebalances: Drifting Out of Position

Market cap rankings shift constantly. A token ranked #73 on Monday might hit #95 by Friday, or surge to #58. Without systematic rebalancing, your portfolio becomes a collection of recent winners or dumpers.

In Q3 2024, Solana ecosystem tokens surged while Ethereum DeFi tokens consolidated. Manual managers who missed weekly rebalances held too much ETH and insufficient SOL exposure. The result: 15-20% underperformance compared to systematically rebalanced portfolios. Data from Token Metrics shows that weekly rebalancing outperforms monthly or quarterly approaches by 8-12% annually.

Tax Reporting Nightmares

Every trade creates a taxable event. Manual managers executing over 200 trades yearly face:

  • Hours spent compiling transaction logs
  • Reconciliation across multiple exchanges
  • Cost-basis tracking for numerous lots
  • High professional accounting fees ($500-2,000+)

Automated solutions like Token Metrics provide transparent transaction logs for each rebalance, simplifying tax reporting and reducing accounting costs.

The Token Metrics Advantage: Research Meets Execution

Token Metrics has established itself as a leading crypto analytics platform, supporting over 50,000 users with AI-powered token ratings, market regime detection, portfolio optimization tools, and trading signals. But analysis alone isn't enough—implementation is crucial.

TM Global 100 Index bridges this gap. It turns research into actionable, tradeable products by automating rebalancing based on Token Metrics' signals and methodology. One click replaces hours of manual work, following a validated systematic approach.

Automation Without Compromise

The best automation is transparent. TM Global 100 offers:

  • Rules-Based Discipline: Bull markets—hold top 100 tokens; bear markets—move to stablecoins
  • Weekly rebalancing every Monday
  • Full methodology disclosure
  • One-Click execution via embedded self-custodial wallet
  • Real-time market insights and holdings visualization
  • Transaction logs with fees and timestamps

This streamlined process allows users to rapidly execute disciplined rebalancing, saving countless hours and increasing operational efficiency while maintaining asset control.

Decision Framework: When to Automate

Automation suits investors who:

  • Hold 15+ tokens and find rebalancing burdensome
  • Miss optimal rebalancing windows due to time constraints
  • Have experienced emotional trading decisions during volatility
  • Spend over 5 hours a week on portfolio management
  • Want broad exposure without manual tracking

Manual management may be suitable for those with fewer positions, active trading infrastructure, or tactical strategies. For most diversified portfolios, automation enhances efficiency and reduces operational errors.

The Compound Effect of Efficiency

Small inefficiencies compound over time. Over five years, a $50,000 portfolio managed manually with a 12% annual return minus 4-2-1% losses yields roughly a 5% net return, ending at about $63,814. A systematic approach with optimizer integration, zero behavioral errors, and regular rebalancing can attain a 13% net return, reaching approximately $92,246—an increase of over $28,000, not counting time saved.

Conclusion: Time Back, Returns Up

Manual crypto portfolio management made sense when portfolios were small and concentrated. Today’s diversified sets require operational discipline to prevent erosion of returns due to execution drag, missed rebalances, and emotional mistakes. Token Metrics built TM Global 100 to turn research into automated, transparent execution, reclaim your time, and boost portfolio discipline—without sacrificing control.

Moonshots API: Discover Breakout Tokens Before the Crowd

Token Metrics Team
5
MIN

The biggest gains in crypto rarely come from the majors. They come from Moonshots—fast-moving tokens with breakout potential. The Moonshots API surfaces these candidates programmatically so you can rank, alert, and act inside your product. In this guide, you’ll call /v2/moonshots, display a high-signal list with TM Grade and Bullish tags, and wire it into bots, dashboards, or screeners in minutes. Start by grabbing your key at Get API Key, then Run Hello-TM and Clone a Template to ship fast.

What You’ll Build in 2 Minutes

Why This Matters

Discovery that converts. Users want more than price tickers, they want a curated, explainable list of high-potential tokens. The Moonshots API encapsulates multiple signals into a short list designed for exploration, alerts, and watchlists you can monetize.

Built for builders. The endpoint returns a consistent schema with grade, signal, and context so you can immediately sort, badge, and trigger workflows. With predictable latency and clear filters, you can scale to dashboards, mobile apps, and headless bots without reinventing the discovery pipeline.

Where to Find The Moonshots API

The cURL request for the Moonshots endpoint is displayed in the top right of the API Reference. Grab it and start tapping into the potential!

How It Works (Under the Hood)

The Moonshots endpoint aggregates a set of evidence—often combining TM Grade, signal state, and momentum/volume context—into a shortlist of breakout candidates. Each row includes a symbol, grade, signal, and timestamp, plus optional reason tags for transparency.

For UX, a common pattern is: headline list → token detail where you render TM Grade (quality), Trading Signals (timing), Support/Resistance (risk placement), Quantmetrics (risk-adjusted performance), and Price Prediction scenarios. This enables users to understand why a token was flagged and how to act with risk controls.

Polling vs webhooks. Dashboards typically poll with short-TTL caching. Alerting flows use scheduled jobs or webhooks to smooth traffic and avoid duplicates. Always make notifications idempotent.

Production Checklist

Use Cases & Patterns

Next Steps

FAQs

1) What does the Moonshots API return?

A list of breakout candidates with fields such as symbol, tm_grade, signal (often Bullish/Bearish), optional reason tags, and updated_at. Use it to drive discover tabs, alerts, and watchlists.

2) How fresh is the list? What about latency/SLOs?

The endpoint targets predictable latency and timely updates for dashboards and alerts. Use short-TTL caching and queued jobs/webhooks to avoid bursty polling.

Support and Resistance API: Auto-Calculate Smart Levels for Better Trades

Token Metrics Team
4
MIN

Most traders still draw lines by hand in TradingView. The support and resistance API from Token Metrics auto-calculates clean support and resistance levels from one request, so your dashboard, bot, or alerts can react instantly. In minutes, you’ll call /v2/resistance-support, render actionable levels for any token, and wire them into stops, targets, or notifications. Start by grabbing your key on Get API Key, then Run Hello-TM and Clone a Template to ship a production-ready feature fast.

What You’ll Build in 2 Minutes

A minimal script that fetches Support/Resistance via /v2/resistance-support for a symbol (e.g., BTC, SOL).

  • A one-liner curl to smoke-test your key.
  • A UI pattern to display nearest support, nearest resistance, level strength, and last updated time.

Next Endpoints to add

  • /v2/trading-signals (entries/exits)
  • /v2/hourly-trading-signals (intraday updates)
  • /v2/tm-grade (single-score context)
  • /v2/quantmetrics (risk/return framing)

Why This Matters

Precision beats guesswork. Hand-drawn lines are subjective and slow. The support and resistance API standardizes levels across assets and timeframes, enabling deterministic stops and take-profits your users (and bots) can trust.

Production-ready by design. A simple REST shape, predictable latency, and clear semantics let you add levels to token pages, automate SL/TP alerts, and build rule-based execution with minimal glue code.

Where to Find

Need the Support and Resistance data? The cURL request for it is in the top right of the API Reference for quick access.

👉 Keep momentum: Get API Key • Run Hello-TM • Clone a Template

How It Works (Under the Hood)

The Support/Resistance endpoint analyzes recent price structure to produce discrete levels above and below current price, along with strength indicators you can use for priority and styling. Query /v2/resistance-support?symbol=<ASSET>&timeframe=<HORIZON> to receive arrays of level objects and timestamps.

Polling vs webhooks. For dashboards, short-TTL caching and batched fetches keep pages snappy. For bots and alerts, use queued jobs or webhooks (where applicable) to avoid noisy, bursty polling—especially around market opens and major events.

Production Checklist

  • Rate limits: Respect plan caps; add client-side throttling.
  • Retries/backoff: Exponential backoff with jitter for 429/5xx; log failures.
  • Idempotency: Make alerting and order logic idempotent to prevent duplicates.
  • Caching: Memory/Redis/KV with short TTLs; pre-warm top symbols.
  • Batching: Fetch multiple assets per cycle; parallelize within rate limits.
  • Threshold logic: Add %-of-price buffers (e.g., alert at 0.3–0.5% from level).
  • Error catalog: Map common 4xx/5xx to actionable user guidance; keep request IDs.
  • Observability: Track p95/p99; measure alert precision (touch vs approach).
  • Security: Store API keys in a secrets manager; rotate regularly.

Use Cases & Patterns

  • Bot Builder (Headless): Use nearest support for stop placement and nearest resistance for profit targets. Combine with /v2/trading-signals for entries/exits and size via Quantmetrics (volatility, drawdown).
  • Dashboard Builder (Product): Add a Levels widget to token pages; badge strength (e.g., High/Med/Low) and show last touch time. Color the price region (below support, between levels, above resistance) for instant context.
  • Screener Maker (Lightweight Tools): “Close to level” sort: highlight tokens within X% of a strong level. Toggle alerts for approach vs breakout events.
  • Risk Management: Create policy rules like “no new long if price is within 0.2% of strong resistance.” Export daily level snapshots for audit/compliance.

Next Steps

  • Get API Key — generate a key and start free.
  • Run Hello-TM — verify your first successful call.
  • Clone a Template — deploy a levels panel or alerts bot today.
  • Watch the demo: Compare plans: Scale confidently with API plans.
