Bridge from OP Mainnet to BNB Smart Chain
Live quotes compared across 30+ bridges and DEXs. Non-custodial — your wallet signs every transaction.
About this route
OP Mainnet. The original optimistic rollup and the reference implementation for the OP Stack, the codebase that Base and a growing list of other chains are built on.
BNB Smart Chain. An independent EVM chain with heavy retail volume, especially around new token launches. It has no relationship to Ethereum consensus, so every route in or out is a true cross-chain transfer.
Transfers between OP Mainnet and other OP Stack chains such as Base are unusually cheap, because the routes share infrastructure and liquidity providers.
There is no native Ethereum bridge here, so every transfer relies on a third-party bridge and its liquidity — compare several routes rather than accepting the first quote.
Common questions
How long does it take to bridge from OP Mainnet to BNB Smart Chain?
Most third-party bridge routes on this pair complete in a few minutes. The quote shown above includes an estimated time for each route, since a cheaper route is sometimes a slower one.
What does it cost to bridge from OP Mainnet to BNB Smart Chain?
The total cost is the bridge's own fee plus gas on OP Mainnet, and the two vary independently by route. Comparing quotes matters most on smaller transfers, where a fixed gas cost can outweigh a better rate.
Is Bospora custodial?
No. Bospora is an interface to the LI.FI routing API. Funds move directly from your wallet to the bridge contract, and every transaction is signed by you.

Bridging carries risk. Contracts can fail and liquidity can move between the moment a quote is shown and the moment it executes. Send a small test amount first when you are using a route for the first time.
