How to bridge to Polygon

Get onto Polygon from any chain and any token. Sweep compares routes and settles it in the token you choose.

Bridge to Polygon

TL;DR

  • Bridge to Polygon from any chain and any token, all in one flow.
  • Sweep compares Relay, Across, Mayan, Symbiosis and others, routing through whichever gives the best rate.
  • No account and no centralized exchange. Your funds stay in your wallet the whole way.
  • Sweep many balances together instead of bridging each one by hand.

What is Polygon?

Polygon is a widely used Ethereum scaling network with very low fees and deep liquidity across DeFi, payments and consumer apps.

Sweep consolidates your scattered balances and delivers the token you want on Polygon, with no separate bridges to juggle.

  4. 4

    Review the route Sweep found and approve it in your wallet.

    Sweep compares Relay, Across, Mayan, Symbiosis and others in real time and picks the cheapest, fastest path, showing the exact amount that will arrive on Polygon and the fee before you sign. Assets sitting on the same chain are batched into a single signature, so you're not approving one transaction per token. Confirm, and your funds land on Polygon — you can follow every leg in the app's history.

How much does it cost to bridge to Polygon?

Two things make up the cost: the gas on the network you're sending from, and the routing provider's fee. Sweep compares its providers in real time and shows exactly what will arrive on Polygon before you confirm, so there's nothing hidden.

There's no account, subscription or extra Sweep charge to use it. Because Sweep routes through whichever path is cheapest, you keep more than you would sending through a single bridge.

Why bridge with Sweep

  • Best rate, automatically. Sweep quotes Relay, Across, Mayan, Symbiosis and others, routing through the cheapest path to Polygon.
  • Many tokens, one flow. Consolidate scattered balances across chains into the token you want on Polygon instead of bridging each one by hand. Assets on the same chain are batched into a single signature.
  • You stay in control. Funds move directly through the providers, and Sweep never holds your assets.
  • No guesswork. You see exactly what lands on Polygon before you approve anything.

Bridging out of Polygon

Leaving Polygon works the same way in reverse. Open Sweep, select your tokens on Polygon, choose the chain and token you want to end up with, and approve it in your wallet. Your assets move straight through the providers and never sit with Sweep.

Frequently asked questions

Most transfers to Polygon settle within seconds to a couple of minutes, depending on network conditions. Sweep automatically picks the fastest available route across its providers.

You pay the source network's gas plus the routing provider's fee. Sweep compares Relay, Across, Mayan, Symbiosis and others in real time and shows exactly what you'll receive on Polygon before you confirm.

No. Sweep needs no account and never takes custody of your funds. You connect your own wallet, and everything moves directly through audited routing providers.

Yes. That's the point of Sweep. You can consolidate scattered balances across several chains into one destination token on Polygon, instead of bridging each one by hand. Assets on the same chain are batched into a single signature.

Sweep routes through audited providers and never takes custody of your assets, so your funds move straight from your wallet to Polygon. You approve every transaction yourself and can see the expected result before you sign.

You can start from almost any token on any supported chain and receive the token you choose on Polygon. Sweep handles the swaps and the bridging in the same flow, so you don't need to hold a specific asset first.

The same way, in reverse. Open Sweep, select your tokens on Polygon, choose the chain and token you want to end up with, and approve it in your wallet.
