wBNB is "wrapped BNB"
Please note that all projects and dApp applications running on the Binance Smart Chain are independently developed by third-party developers. They are not audited by Binance official team.Binance Smart Chain is an entirely open-source and open community, which means everyone and all project parties can participate. All opportunities and risks also exist at the same time. You need to identify and prevent risks carefully. This is also the charm of the DeFi world.
BNB is the native currency built on the Binance Smart Chain.
When a dApp (decentralized app) is built off of the Binance Smart Chain, it usually implements its own form of Token. Think Band’s BAND Token, or Chainlink LNK Token.
BEP20 is a standard allowing any tokens on Binance Smart Chain to be used by other applications: from wallets to decentralized exchanges in a consistent way. wBNB follows BEP20 standard except that there is no owner(). Besides, this standard interface also extends ERC20 to facilitate cross chain transfer. https://github.com/binance-chain/BEPs/blob/master/BEP20.md
