BNB Chain Bridge is a cross-chain bridge aggregator enabling asset transfers between various blockchain networks and BNB Smart Chain while providing optimal routes and competitive rates for cross-chain transactions.
opBNB Bridge is the native bridge for moving BNB and BEP-20 tokens between BNB Smart Chain and the opBNB Layer 2. Deposits are locked in a standard bridge contract on BNB Smart Chain and credited on opBNB, while withdrawals are proven against opBNB state posted to BNB Smart Chain before funds are released. It serves as the canonical route for moving assets onto opBNB, with deposits and withdrawals made from a dedicated web interface.
BNB Greenfield Bridge is the native bridge for transferring BNB between BNB Smart Chain and the BNB Greenfield storage network. It relays transfers through the cross-chain messaging layer that connects the two networks, in either direction. Users move funds from a web interface by connecting a wallet holding BNB on the source network.
