With Native Bridges, bridging off a Rollup to the Settlement Chain is a multi-step process and requires multiple transactions. There is also a significant wait period (usually 7 days).
Learn more about Settlement Chains here.
Please note:
Native Bridges are a great option for moving larger token amounts. But when moving small amounts, the gas costs for the transactions can sometimes add up, making it too expensive. For bridging smaller amounts we recommend choosing a different route, either Across or Hyperlane if available.
Step 1 —
Connect your wallet
Be sure your wallet supports the Rollup and Settlement Chain you will be bridging to.
Learn more about connecting your wallet.
Step 2 —
Choose your chains
Choose the Rollup you want to bridge off, then select the corresponding Settlement Chain to bridge onto.
Step 3 —
Select a token to bridge
Select the token you want to bridge, and enter the amount.
Note: If you cannot find a particular token, it may not have been deployed and available on the Rollup yet.
Please note:
Superbridge will automatically pick the Native Bridge if it is available. If you would like to choose another bridge instead of the Native one, you can select it by pressing the bridge provider button and select whichever you prefer.
Step 4 —
Review your bridge
Tap the Review Bridge button and review your bridge details.
Please note the multiple steps, each approximate transaction cost, and any extra wait time.
To proceed check the boxes indicating you understand the following:
The approximate time that the bridge will take including any wait periods
(There will usually be a 7 day wait period).That the indicated network fees for each step are approximate and are subject to change depending on network activity.
That you cannot cancel or reverse a bridge once it has been started.
Step 5 —
Start your bridge
Depending on the token, you may need to approve it first. This is so the bridge contract can use your funds for bridging. Note that we only request an approval for the amount you're bridging, this helps secure your wallet in case the bridge contracts are compromised.
Next, start your bridge and continue with the transaction in your wallet.
Once your bridge transaction has been successfully started you can safely navigate away from this screen.
To get back to this screen select the activity button.
You can view your bridge progress from the activity screen.
Step 6 —
Proving (OP Stack only)
Note:
This step only applies to bridging off from Rollups powered by Optimism's OP Stack.
Once the initial transaction is successful, you will need to wait for the time noted in the review screen. Each rollup differs in how long this takes, but it's usually about an hour.
When the wait is over, you will be able to 'prove' your bridge.
To prove your bridge, open your activity feed by tapping the 🕘 button at the top right of the screen.
Your bridge will display a Prove button. Tap it and continue with the transaction in your wallet. Once the transaction is successful, you will then proceed to the Challenge Period.
Step 7 —
Wait for the Challenge Period
The Challenge Period is a security measure built into the Native Bridge contracts for Optimism and Arbitrum. You will need to wait for the designated period of time before continuing with your bridge. The Challenge Period usually takes 7 days.
Step 8 —
Finalize your bridge
Now the Challenge Period is complete you can finalize your bridge and claim your tokens on the Settlement Chain.
To finalize your bridge, open your activity feed by tapping the 🕘 button at the top right of the screen.
Your bridge will display a Finalize button. Tap it and continue with the transaction in your wallet. Once the transaction is successful, your tokens will appear in your wallet shortly after.
