Ethereum ERC20 contract address

Writing an ERC20 Token in Solidity

An ERC-20 token contract is defined by the contract’s address and the total supply of tokens available to it, but has a number of optional items that are usually provided as well to provide more detail to users. These are the token’s name, its symbol, and the number of decimals.

A token contract is simply an Ethereum smart contract . “Sending tokens” actually means “calling a method on a smart contract that someone wrote and deployed”. At the end of the day, a token contract is not much more a mapping of addresses to balances, plus some methods to add and subtract from those balances.

But not all smart contracts are tokens , according to Martha Bennett, a principal analyst at Forrester Research. “You can have smart contracts running on Ethereum that trigger an action based on a condition without an ERC-20 or ERC-721 token involved,” she said.
