$BNB BNB (Build and Build) is the native cryptocurrency of the Binance ecosystem, originally launched as Binance Coin in 2017. Initially built on Ethereum as an ERC-20 token, BNB later migrated to Binance Chain and now powers Binance Smart Chain (BSC), enabling smart contracts, decentralized apps (dApps), and DeFi services. BNB is used to pay trading fees on Binance Exchange at discounted rates, participate in token sales, and cover transaction fees on BSC. It also supports cross-chain transfers and utility in partner platforms. Binance conducts quarterly token burns to reduce supply and support value. BNB is central to Binance’s expanding ecosystem, including decentralized finance, gaming, and NFTs, making it one of the most widely used utility tokens in the crypto space.
