Cross-chain bridge

Cross-chain bridge is a base infrastructure component of Ankr AppChains implemented in Chainscanner. AppChain's bridge solution is powered by BridgeHub (opens in a new tab).

The bridge is a single gateway to all AppChains. It allows users to quickly transfer their assets between different AppChains.

You can bridge assets on:

• Testnet, as a developer who's setting up and testing out their AppChain.
• Mainnet, as a user or a developer who needs to bridge assets in or out of an AppChain.

Use bridge

Connect your wallet

To connect your wallet:

1. Visit the Chainscanner's dashboard (opens in a new tab) (preselected meta-apes network).
2. Select a network to access. The selection popup shows you Mainnet networks.
   To see available Testnet networks, click on Access Testnets.
3. Click Connect wallet in the top-right corner.
4. In your MetaMask, select an account to connect and click Next, then click Connect.

Bridge assets

To bridge your assets to an AppChain of your choice:

1. Visit the Bridge (opens in a new tab) (preselected meta-apes network).
2. Select a network to access. The selection popup shows you Mainnet networks.
   To see available Testnet networks, click on Access Testnets.
3. Choose a From and To network, enter a desired Token amount, and click Approve to allow the Bridge to access that amount.
4. Confirm the approval transaction in MetaMask.
5. Click Send to bridge tokens. Also, check the current network liquidity capacity to make sure it's more than what you're bridging.
6. Confirm the bridging transaction in MetaMask.
7. Click Switch network to continue.
8. Confirm the switching in MetaMask.
9. Stay on the page and wait a moment for the tokens to be auto-claimed in the destination network. When the Claim check is there, you'll see the "Bridge successful!" message and can Close the page.

Recover non-finished bridging

Sometimes you may have a non-finished bridging. This may happen due to an OS crash, closed tab, lost internet connection, and many other reasons. If you managed to Send tokens from the source network and confirm the bridging transaction (#6 in Bridge assets), you will have that transaction in your MetaMask history.

To recover a non-finished bridging:

1. In MetaMask, switch to the network you were bridging from and find the Deposit Token transaction from #5–6 in Bridge assets. Copy this transaction hash.
2. Visit the Bridge (opens in a new tab) (preselected meta-apes network).
3. Click Finish bridge above the To field.
4. Choose the source Network as it was in the original bridging attempt, enter the transaction hash from #1, and click Switch network to auto-claim your tokens in the destination network. The switching action is equivalent to #7 in Bridge assets.
