BEP-20 tokens are a type of fungible token standard used on BNB Chain, which is based on the Ethereum-like framework of ERC-20 tokens. BNB Chain, created from a fork of the Go Ethereum protocol, uses a unique consensus mechanism known as Proof of Staked Authority (PoSA) involving 21 validators supported by BNB delegators. The network, known for its speed and low cost, is EVM-compatible, allowing for the deployment of Ethereum contracts. To transfer assets from Ethereum to BNB Chain, users can utilize the Binance Bridge, which facilitates the creation of BEP-20 versions of Ethereum assets. Developers can create BEP-20 tokens using tools like Remix IDE and OpenZeppelin contracts, and deploy them on the BNB Chain testnet using a wallet like Brave Wallet. Once deployed, these tokens can be verified on the BNB Chain testnet and potentially used for various applications, including DeFi and governance protocols, with further opportunities for enhancement and integration with Chainlink services.
