BNB has the highest market capitalization in CEX tokens. It is created by Binance, one of the world's leading cryptocurrency exchanges.Launched in 2017, BNB was initially an ERC-20 token on the Ethereum blockchain but migrated to Binance's proprietary blockchain, Binance Chain, in 2019.

BNB is unique due to its utility and integration within the Binance platform. Users can use BNB to pay for trading fees on the exchange, participate in token sales on Binance Launchpad, and make in-store payments where it's accepted.  Moreover, BNB is the native token of Binance Smart Chain (BSC), a blockchain platform for developing decentralized applications (DApps) and DeFi protocols.

In June 2023, the U.S. Securities and Exchange Commission (SEC) filed a lawsuit against Binance, its CEO Changpeng Zhao, and two other affiliated subsidiaries. The defendants are accused of violating a series of securities laws, including illegal transfer of customer funds, violation of U.S. securities trading rules, operating illegal trading platforms, concealment, and fraud. At the same time, BNB was listed as a security by the SEC, which caused BNB's market value to drop by more than 20% on that day, and it has not recovered so far.
