Bridge from BNB Smart Chain to Arbitrum One

Live quotes compared across 30+ bridges and DEXs. Non-custodial — your wallet signs every transaction.

About this route

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.

Arbitrum One. The largest Ethereum rollup by value locked, and the default home for perpetuals and other trading-heavy protocols. Fees are a fraction of mainnet while keeping Ethereum security.

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.

Arbitrum has by far the deepest third-party bridge liquidity of any L2, so large transfers here usually quote a tighter rate than to smaller rollups.

Common questions

How long does it take to bridge from BNB Smart Chain to Arbitrum One?

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 BNB Smart Chain to Arbitrum One?

The total cost is the bridge's own fee plus gas on BNB Smart Chain, 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.

Other routes

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.
