$BNB is the native coin of the BNB Chain ecosystem, originally launched in 2017 as Binance's exchange token.
Today it is used to:
1. Pay gas fees on BNB Smart Chain, opBNB and other BNB Chain components.
2. Participate in on-chain governance for $BNB Chain proposals.
3. Act as a strategic reserve asset with an Auto-Burn mechanism that gradually reduces total supply toward 100 million BNB.
BNB evolved from an ERC-20 token on Ethereum to its own mainnet in 2019, and sits at the center of Binance's broader trading, DeFi, gaming, and Web3 ecosystem.
