Ethereum Request for Comment 20, commonly known as ERC20, is a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens. These tokens are blockchain-based assets that have value and can be sent and received. The standard defines a set of rules that apply to all ERC20 tokens, ensuring compatibility within the Ethereum ecosystem.
Where It Is Used
ERC20 tokens are primarily used on the Ethereum blockchain. They facilitate transactions involving digital assets and are used to create and issue smart contract-based tokens.
Why It Is Used
The ERC20 standard is used to ensure consistency and interoperability among tokens within the Ethereum blockchain. It simplifies the process of creating new tokens by providing a blueprint that developers can follow, making token integration easier for wallets, exchanges, and other smart contracts.
Who Uses It
Who Issues It
Individual developers or organizations can issue ERC20 tokens by deploying a smart contract that adheres to the ERC20 standard on the Ethereum blockchain.
Who Regulates It
There is no central regulatory body for ERC20 tokens. However, the deployment and interaction with these tokens are governed by the immutable rules of the Ethereum blockchain. Regulatory compliance for specific uses of ERC20 tokens (e.g., in ICOs or token sales) falls under the jurisdiction of local financial regulatory bodies.

Real-world Analogy
Consider ERC20 tokens as “event tickets” within the Ethereum “stadium.” Each ticket (token) follows a standard format (ERC20), ensuring that they can be used across various events (DApps) within the stadium, from concerts (DeFi platforms) to sports games (governance in DAOs).
