BEP20

BEP20 is a token standard on the Binance Smart Chain (BSC) for fungible tokens. It is designed to be compatible with wallets, explorers, and decentralized applications on the Binance Smart Chain, mirroring the ERC-20 standard used on Ethereum. BEP20 defines a common interface that enables tokens to be easily managed and transferred across the BSC ecosystem.

Core functions and metadata define the BEP20 interface. At a minimum, a BEP20 contract implements totalSupply(), balanceOf(address owner), transfer(address to, uint256 value), approve(address spender, uint256 value), transferFrom(address from, address to, uint256 value), and allowance(address owner, address spender). It also provides metadata through name(), symbol(), and decimals(). The contract must emit Transfer and Approval events to allow wallets and dashboards to track token activity.

Implementation and deployment on BSC typically involve writing a Solidity smart contract that adheres to the BEP20 interface, compiling to Ethereum Virtual Machine (EVM) bytecode, and deploying on the Binance Smart Chain. BEP20 tokens are fungible and are intended to be interoperable with other BEP20 tokens and DApps on BSC. While 18 decimals are common, the decimals value is defined by each token.

Interoperability and use on BSC are broad, with BEP20 tokens supported by major wallets and DeFi protocols on the chain. They are widely tradable on BSC-based exchanges and used in liquidity pools, lending, and yield farming within the Binance Smart Chain ecosystem.
