BNB (Build and Build), originally known as Binance Coin, is the native cryptocurrency of the Binance ecosystem, one of the largest cryptocurrency exchanges globally. Launched in 2017 on the Ethereum blockchain as an ERC-20 token, BNB later migrated to Binance's own blockchain, BNB Chain. It is used to pay for trading fees, participate in token sales, and access various decentralized applications (dApps) within the Binance ecosystem. BNB also supports smart contracts and DeFi protocols. Binance regularly burns (destroys) a portion of BNB supply to reduce inflation and maintain value. Its utility and ecosystem integration make it a key crypto asset.
