How do I get an ERC20 contract?

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.

Ethereum Token (ETH) ERC20 Token in Binance Smart Chain Mainnet. Token is implemented as ERC20 smart contract with address 0x2170ed0880ac9a755fd29b2688956bd959f933f8 .

Just like other Ethereum tokens, ERC20 tokens are implemented as smart contracts and executed on the Ethereum Virtual Machine (EVM) in a decentralized manner.
