Bridge from Avalanche C-Chain to Polygon PoS

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

About this route

Avalanche C-Chain. The EVM-compatible chain of the Avalanche network, with fast finality measured in seconds and a substantial institutional and real-world-asset presence.

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.

Avalanche finalises in a couple of seconds, so the bridge itself is almost always the slow part of a transfer here, not the chain.

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 Avalanche C-Chain 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 Avalanche C-Chain to Polygon PoS?

The total cost is the bridge's own fee plus gas on Avalanche C-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.
