Using Mantle Bridge
How to deposit and withdraw assets using official Mantle Bridge
Mantle v2 Tectonic has been released, please move to the new documentation!
You can use the testnet bridge to get acquainted with the UI of the official Mantle bridge. The official Mantle Bridge on Mainnet operates in exactly the same way connecting to Ethereum Mainnet.
Deposit $MNT
Follow the steps below to deposit your tokens from Goerli to Mantle Testnet:
Select the "Deposit" tab and enter the amount of $MNT you want to bridge over to Mantle Testnet, and then click on the button at the bottom to proceed with token approval.
Enter an amount to approve to the contract. You can choose an amount you're comfortable with, but make sure its equal to or greater than the amount you're depositing. Then click on the "Next" button.
Click on the "Approve" button to approve the amount you entered. Approval may take some time, about 10 seconds or so.
Once approval is successful, you'll see the "Deposit Tokens to L2" button. Click on it to proceed to confirmation.
Here you'll be able to see the deposit amount and approximate time it'll take to complete the deposit operation. Finally, click on the "Confirm" button to send a deposit transaction. You'll need to confirm the transaction in your wallet too.
Feel free to check the transaction status by click on the "Goerli Explorer" button. Once complete the balance will be reflected in your L2 testnet wallet.
Withdraw $MNT
Follow the steps below to withdraw your tokens from Mantle Testnet to Goerli:
Select the "Withdraw" tab and enter the amount of $MNT you want to bridge over to Goerli, and then click on the "Withdraw Tokens from L2" button at the bottom.
You'll be able to see the withdraw amount and an approximation for the amount of time it will take for the token transfer. Note that once complete, the amount still needs to be claimed on L1 for it to land in your wallet. Check the checkboxes, and click on the "Confirm" button to send a withdraw transaction.
Confirm the operation in your wallet. Feel free to check out the transaction status on the Explorer by clicking on the "Mantle Testnet Explorer" button.
You'll be able to claim the $MNT tokens on Goerli once available by sending a transaction from your wallet. Click on your wallet address in the top-right to see all your withdrawals and deposits.
Click on the "Claim" button and confirm the transaction in your wallet. The $MNT will show up in your Goerli wallet once the transaction is successfully sent.
