# ERC-20/BEP20 token

Both ERC-20 and BEP-20 are token standards.

ERC stands for Ethereum Request for Comment which means that when creating a smart contract on the Ethereum blockchain, Polygon, Avalanche, etc, it’s imperative to adhere to this standard.

BEP-20 is also a token standard and an extension of the ERC-20. Binance Smart Chain tokens adhere to BEP-20.

CryptEx constructor allows building a smart contract for either one of these standards, depending on the blockchain network you choose. In this case, you are able to define the name, the symbol, the total supply of the token, and several other details. After specifying all these items, the creation of the token only takes a few seconds.

If you choose an option to create a contract with an audit, you will receive an automatically generated report, based on audits performed by both HashEx and Paladin auditing companies.
