How to bridge to Base

Get onto Base from any chain and any token. Sweep finds the best route and settles it in the token you want.

Bridge to Base

TL;DR

  • Bridge to Base 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 Base?

Base is Coinbase's Ethereum layer 2: low fees, fast finality, and one of the deepest DeFi and app ecosystems outside of mainnet.

You can move funds onto Base from any other chain without touching a centralized exchange. Sweep routes your assets across bridges and DEXs and lands them on Base as the token you choose.

  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 Base 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 Base — you can follow every leg in the app's history.

How much does it cost to bridge to Base?

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 Base 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 Base.
  • Many tokens, one flow. Consolidate scattered balances across chains into the token you want on Base 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 Base before you approve anything.

Bridging out of Base

Leaving Base works the same way in reverse. Open Sweep, select your tokens on Base, 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.
