Binance Coin

BNB is the native token of the BNB Chain ecosystem, originally launched in 2017 as Binance Coin to support fee discounts on the Binance exchange. The token began as an ERC-20 asset on Ethereum before migrating to its own infrastructure as the network grew into a multi-chain environment.

The ecosystem is built around two interoperable chains. BNB Beacon Chain handles staking and governance for the network, while BNB Smart Chain (BSC) is an EVM-compatible Layer 1 that supports smart contracts and decentralised applications. A more recent addition, opBNB, is a Layer 2 rollup that further reduces fees and increases throughput for high-volume use cases. BNB serves as the gas token across these environments and as the primary asset for staking with validators.

BNB also retains its original utility on the Binance exchange, including fee discounts and access to launchpad products. The supply is reduced over time through periodic burns tied to onchain activity and protocol parameters. Within the broader landscape, BNB sits among the largest exchange-affiliated networks, combining centralised exchange utility with a sizeable EVM-compatible smart contract ecosystem.

Exchange-affiliated networks combine centralised trading platforms with smart contract chains, providing onramps, liquidity and ecosystem development funding within a single environment. BNB sits within this category as one of the largest examples by total addressable users. Readers tracking how these ecosystems develop can explore broader trends across crypto and Web3.
