$BNB BNB, originally Binance Coin, is the native cryptocurrency of the BNB Chain ecosystem, developed by the world's largest crypto exchange, Binance. Launched in 2017 as an ERC-20 token on Ethereum, it later migrated to its own blockchain, the BNB Chain (now comprising BNB Smart Chain and BNB Beacon Chain).

BNB has evolved from a utility token offering trading fee discounts on Binance to powering a vast ecosystem. It's used for transaction fees on the BNB Chain, participating in decentralized finance (DeFi) activities like staking and yield farming, and for governance. Its deflationary model, with regular "burns" reducing supply, aims to increase its value. BNB also facilitates payments for goods and services across various platforms, making it a versatile asset in the crypto space.
