Bridge from Polygon PoS to Arbitrum One
Live quotes compared across 30+ bridges and DEXs. Non-custodial — your wallet signs every transaction.
About this route
Polygon PoS. A long-running proof-of-stake chain with very low fees and broad wallet and payment-processor support. It runs its own validator set rather than inheriting Ethereum security.
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.
Polygon is a sidechain, not a rollup, so its native bridge has no fraud-proof waiting period — but you are trusting Polygon validators rather than Ethereum for the duration.
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 Polygon PoS 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 Polygon PoS to Arbitrum One?
The total cost is the bridge's own fee plus gas on Polygon PoS, 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.
