Bridge from Ethereum to Polygon PoS

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

About this route

Ethereum. The settlement layer that almost every other chain here ultimately posts to. It holds the deepest liquidity and the longest-lived protocols, at the cost of the highest fees.

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.

Because rollups settle here, Ethereum is the one chain where a bridge transfer can be slower than the chain itself — the delay comes from the rollup you are leaving, not from Ethereum.

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.

Common questions

How long does it take to bridge from Ethereum to Polygon PoS?

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 Ethereum to Polygon PoS?

The total cost is the bridge's own fee plus gas on Ethereum, 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.
