$BNB BNB (Build and Build), originally launched as Binance Coin in 2017, is the native cryptocurrency of the Binance ecosystem. Initially built on Ethereum, BNB migrated to its own blockchain, BNB Chain, enabling faster and more scalable transactions. BNB is widely used for trading fee discounts on Binance, staking, payments, and participation in token sales on Binance Launchpad. It also powers smart contracts and decentralized applications (dApps) on the BNB Chain. With a fixed supply of 200 million coins and a regular burn mechanism, BNB aims to become more deflationary over time. It plays a central role in Binance's growing Web3 infrastructure.
