What is ERC-20?

ERC-20 (or Ethereum Request for Comments 20) is a token standard for developing fungible tokens on the Ethereum blockchain. The cryptocurrency tokens like Tether (USDT), USD coin (USDC), Wrapped Bitcoin (WBTC), and Dai (DAI) are a few examples of ERC-20 tokens.

ERC-20 tokens don’t have their own blockchain. Instead, the tokens use smart contracts on the Ethereum blockchain and Ether for transaction fees.
