Since its launch, the Ethereum blockchain has attracted developers, businesses, and entrepreneurs, spawning a erc20 address wallet industry of users launching smart contracts and distributed applications. What is the ERC standard?

These are erc20 erc20 address wallet wallet documents that outline standards for programming on Ethereum.
