As of May 2019, Coinbase does not support BEP2. BEP2 is a new standard for tokens on the Binance Chain, which is a decentralized exchange launched by Binance. Binance Chain uses the Delegated Proof of Stake (DPoS) consensus mechanism. DPoS is a variant of the Proof of Stake (PoS) consensus algorithm.
Under PoS, blockchain network participants validate transactions and create new blocks in return for rewards. In DPoS, participants (called “delegates”) are elected by the community to validate transactions and create new blocks. The top 20 delegates by stake weight are chosen to produce blocks. Coinbase has not announced any plans to support BEP2.
