ERC-20 is the technical standard upon which the issuance of smart contracts on the Ethereum blockchain is based. "ERC-20" refers to Ethereum Request for Comment #20, which was a format for standards development used earlier by the Ethereum Foundation.

All transactions in tokens, such as for transfers or changes to a tokens database, take place on the Ethereum blockchain and are paid for in ether.[1] ERC-20 specifies the following six mandatory standards for use in smart contracts:

As of July 12, 2018 there had been 99,228 ERC-20 tokens issued.[3] The number of tokens exploded over the next two-and-a-half years, tripling to more than 337,073 on November 23, 2020.[4] References[edit]
