#ReboundRally BNB (formerly Binance Coin) is a cryptocurrency from the Binance exchange that was launched in July 2017 through an ICO. Currently, BNB is used for transaction fees and to participate in other activities within the BNB Chain ecosystem.

In its early days, BNB was built on the Ethereum Blockchain (ERC-20). Until 2020, Binance switched to using Binance Smart Chain (a blockchain built on Ethereum's EVM) as the main blockchain and focused on developing BSC (BEP-20) instead of Binance Chain (BEP-2).

As of February 2022, Binance and CZ announced the launch of BNB Chain to develop MetaFi, and this will also be the blockchain using BNB as gas fee, with the new name for BNB being "Build and Build" instead of "Binance Coin" as before.$BNB
