BNB Coin (formerly Binance Coin, now stands for "Build and Build") is a cryptocurrency created by Binance, the largest cryptocurrency exchange in the world.

Originally launched as an ERC-20 token on the Ethereum blockchain, BNB later migrated to its own blockchain, namely Binance Chain, and is now operating in the BNB Chain ecosystem (a combination of Binance Chain and Binance Smart Chain/BSC).
