Cryptocurrencies have revolutionized the way we think about digital assets and transactions. Among the many innovations in the blockchain space, ERC20 tokens have emerged as a prominent standard for creating and managing tokens on the Ethereum blockchain. 

In this comprehensive guide, we will explore what ERC20 tokens are, their history, how they work, their importance and impact, advantages and disadvantages, and provide a list of top ERC20 tokens. So, let's dive in and unravel the fascinating world of ERC20 tokens.

What is ERC20?

ERC20 stands for Ethereum Request for Comment 20 and is the technical standard for creating fungible tokens on the Ethereum blockchain. 

Unlike non-fungible tokens (NFTs), which are unique and not interchangeable, ERC20 tokens are fungible, meaning they can be exchanged on a one-to-one basis with other tokens of the same type. 

These tokens represent assets, rights, ownership, access, or even cryptocurrencies that are not unique in themselves but can be transferred.

The ERC20 standard enables developers to create smart-contract-enabled tokens that can be used with various products and services. 

Since its implementation, most tokens in the Ethereum ecosystem have been created using the ERC20 standard, making it a crucial part of the Ethereum blockchain's functionality.

History of ERC20

To understand the significance of ERC20 tokens, let's look at their history. In 2015, as smart contracts gained popularity, developers realized the need for a standardized token methodology within the Ethereum ecosystem. 

Each application would require its own token without a standard, leading to interoperability issues and difficulties in exchanging tokens between different applications.

To address this problem, developer Fabian Vogelsteller proposed the ERC20 standard 2015 through the Ethereum Request for Comment (ERC) process on the project's Github page. 

The proposal, initially known as ERC-20 due to its designation as the twentieth comment, was later approved and implemented as Ethereum Improvement Proposal 20 (EIP-20) in 2017.

The approval and implementation of the ERC20 standard ensured that all smart contract tokens implemented on the Ethereum blockchain would adhere to the same set of rules, making them compatible and easily exchangeable.

How Does ERC20 Work?

To understand how ERC20 tokens work, let's delve into their underlying structure and functionality. ERC20 tokens consist of a list of functions and events that must be implemented in a token's smart contract to be considered ERC20 compliant.

ERC20 Functions

The ERC20 standard defines six mandatory functions that a token must have:

  • TotalSupply: This function returns the total number of tokens ever issued.
  • BalanceOf: The BalanceOf function allows users to check the balance of a specific token owner's account.
  • Transfer: The Transfer function automatically transfers a specified number of tokens to a designated address.
  • TransferFrom: This function allows the automatic transfer of a specified number of tokens from one address to another.
  • Approve: The Approve function grants permission to a designated address to withdraw a specific number of tokens from the token owner's account.
  • Allowance: The Allowance function returns the number of tokens approved for withdrawal by a spender from the token owner's account.

These functions provide a standard interface for ERC20 tokens, allowing them to be easily accessed, recognized, and used within the Ethereum ecosystem.

ERC20 Events

In addition to functions, ERC20 tokens also include two mandatory events:

  • Transfer: The Transfer event is triggered when a transfer of tokens is successfully executed.
  • Approval: The Approval event logs the approval of a specific address to spend a certain number of tokens.

These events help keep track of token transfers and approvals within the blockchain.

Optional ERC20 Features

Although the six functions and two events mentioned above are mandatory for ERC20 compliance, token developers can include additional features to enhance the token's usability. These optional features include:

  • Token Name: Tokens can have a name that represents their identity.
  • Token Symbol: Tokens can have a symbol as a shorthand representation of their name.
  • Decimal Points: Tokens can have decimal points to allow for fractional values.

Including these optional features provides more information and clarity about the token, making it easier for users to understand and interact.

The Importance and Impact of ERC20

The ERC20 standard has profoundly impacted the blockchain and cryptocurrency industry. Its importance lies in the fact that it introduced a standardized framework for creating tokens on the Ethereum blockchain, fostering interoperability and compatibility among different tokens and applications. Let's explore some key reasons why ERC20 is significant.

This integration equips your crypto applications with intelligent, data-driven capabilities to support smarter trading and research.

Getting Started: Building the Agent

The integration process begins with cloning a GitHub repository (public upon video release), which includes everything needed to run a Token Metrics x LangChain demo agent. After installing the dependencies and opening the codebase in a code editor, you’ll find a fully documented README that walks you through the setup.

Step 1: Install Dependencies 

Navigate to the project directory and install the required packages using:

‍

Step 2: Configure Environment Variables

Before spinning up the agent, add your Token Metrics API key and your LLM API key (Openai, gemini, etc..) to the .env file. These credentials authorize the agent to access both Token Metrics and your chosen LLM.

Step 3: Define and Run the Agent 

The agent logic is explained directly in the README and starter code sample, making it easy to follow and customize. You’ll find clear instructions and code snippets that guide you through setting up the agent’s capabilities.

Here’s how the agent works in practice:

  • It queries tokens with a valid Trader Grade
  • Filters tokens with Bullish AI signals
  • Compares Trading Signal ROI vs Holding ROI
  • Filters out tokens that aren’t outperforming with active trading

In the test case, it identifies BANANAS S31 as a top candidate:

  • High trader grade
  • Bullish signal
  • Strong Trading Signal ROI (better than holding)

At the end of its analysis, the bot outputs a summary of:

  • Overall market sentiment
  • Top token opportunities
  • Macro-level recommendations

In this case, while BANANAS S31 stood out, the overall market leaned neutral with a slight long-term bearish bias, a useful snapshot for any trader.

Switching to the Advanced Agent

LangChain’s flexibility allows the same bot to switch into an interactive chatbot by attaching memory to the agent. Users can now type in:

“What are the top 3 tokens to watch today?”
“Is the market bullish or bearish?”
“Give me DeFi tokens with bullish signals.”

The agent can dynamically select and chain together specialized crypto analysis tools in response to your questions. This means the agent doesn’t just answer queries with static information but it actively pulls the latest Token Metrics data, applies AI-driven analytics, and synthesizes insights using multiple sources and methods.

The crypto market is rapidly evolving, and with it, the way investors approach asset allocation. Traditional token picking is being replaced by smarter, more diversified strategies like crypto indices. But as AI enters the scene, a new generation of indices—AI crypto indices—is emerging. So, what’s the difference? And which is better for investors in 2025?

In this guide, we break down the key differences, advantages, and use cases of crypto indices vs AI crypto indices, helping you decide which is better for your investment strategy.

What Are Crypto Indices?

A crypto index is a curated basket of cryptocurrencies grouped based on certain criteria such as market capitalization, sector (like DeFi or NFTs), or performance. Just like stock market indices (e.g., S&P 500), these indices offer passive exposure to a segment of the market, allowing investors to diversify without manually picking individual tokens.

Types of Crypto Indices:

  • Market Cap Indices – Top 10, Top 25, or Top 100 coins by market cap
  • Sector-Based Indices – DeFi, Gaming, Memecoins, RWA (Real World Assets), etc.
  • Performance-Based Indices – Best-performing assets over a defined period

Crypto indices are typically rebalanced at regular intervals (e.g., weekly or monthly) and follow fixed rules.

What Are AI Crypto Indices?

AI crypto indices take things a step further by using artificial intelligence and machine learning models to dynamically manage the index.

Unlike static or rule-based crypto indices, AI crypto indices continuously analyze data—such as price action, sentiment, volume, momentum, and on-chain signals—to adjust holdings in real-time or near real-time.

Features of AI Crypto Indices:

  • AI-Powered Rebalancing: Allocations change based on market signals, not fixed schedules
  • Market Timing: Enter or exit positions when bullish or bearish conditions are detected
  • Signal-Based Entry/Exit: Move to stablecoins when the AI model predicts a downturn
  • Multi-Factor Analysis: Combines technical, fundamental, and sentiment indicators

Benefits of Traditional Crypto Indices

  1. Simplicity
    Crypto indices are easy to understand and ideal for beginners who want broad exposure without analyzing charts.
  2. Diversification
    Instead of betting on one token, investors gain exposure to a group, reducing risk.
  3. Low Maintenance
    Once you invest, the portfolio is rebalanced automatically based on set rules.
  4. Transparency
    Rules and components are clear. You know what’s in your index and when it changes.

Benefits of AI Crypto Indices

  1. Smarter Market Timing
    AI models detect bullish or bearish signals and adjust the portfolio accordingly—buying when momentum builds, selling when risk rises.
  2. Higher Alpha Potential
    By reacting faster to changing market conditions, AI indices often outperform static ones in volatile markets.
  3. Dynamic Asset Allocation
    Allocations aren’t fixed—they adapt based on hundreds of real-time data points like sentiment, on-chain activity, and volatility.
  4. Built-in Risk Management
    When bearish signals appear, AI indices can exit positions and shift to stablecoins—helping protect capital in downturns.

Which Is Better in 2025?

The answer depends on your investment style, risk tolerance, and goals:

Choose Crypto Indices if:

  • You prefer a hands-off, passive approach
  • You're a beginner looking for simple exposure
  • You value transparency and low complexity
  • You're investing for the long term regardless of market cycles

Choose AI Crypto Indices if:

  • You want an actively managed experience without managing trades yourself
