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

How much does it cost to bridge to Blast?

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

Bridging out of Blast

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