ERC-20
A standard for fungible tokens on Ethereum, enabling interoperability across dApps.
What is ERC-20?
ERC-20 (Ethereum Request for Comment 20) is a technical standard for fungible tokens on the Ethereum blockchain, introduced in 2015. It defines a set of rules and functions (e.g., transfer, balanceOf, approve) that ensure tokens are interchangeable and compatible with dApps, wallets, and exchanges. Widely used for cryptocurrencies, stablecoins (e.g., USDT, USDC), and utility tokens, ERC-20 tokens power decentralized finance (DeFi) and other applications. Its standardization simplifies integration, making it a cornerstone of Ethereum’s token ecosystem.
