Ethereum Request for Comments (ERC) is the official protocol used by smart contract developers on the Ethereum blockchain. It’s also used for making suggestions for improving the Ethereum network.

ERC-20 is the twentieth proposal for updating the Ethereum blockchain and contains the technical specifications for tokens issued on the blockchain.

Implementation of the ERC-20 protocol has simplified the process of adding new coins to crypto exchange platforms. Once a platform supports ERC-20, it’s possible to add many different tokens without generating new code for each of them.

Among ERC-20 tokens, CEX.IO currently supports Tether (USDT), Gemini Dollar (GUSD), OmiseGO (OMG), Basic Attention Token (BAT), and United States Dollar Coin (USDC) and a range of De-Fi tokens.
