Wrapped BNB (WBNB) is a crypto-currency token that represents Binance Coin (BNB) on the BNB Smart Chain (BEP20) platform. It accelerates Binance transfers across different blockchains and enables BNB to be used within various blockchain networks. Each WBNB coin is backed 1:1 by a Binance asset, making it a wrapped version of BNB.
