BNB is the native currency of the Binance platform, which is one of the largest cryptocurrency trading platforms in the world. BNB was initially launched as a token on the Ethereum network (ERC-20) in 2017 during the initial coin offering (ICO), but was later migrated to the Binance Chain after the launch of that network.
