Bridging on Mantle Mainnet

Bridging to Mantle has never been easier. This step-by-step guide will walk you through the entire process, providing all the necessary instructions for bridging to and from Mantle Network Mainnet.

After reading this guide, you will understand:

  • The deposit process
  • The withdrawal process
  • How to view your account
  • Details about the $MNT Bonus

Deposit on Mantle L2

  • Navigate to our official Mainnet Bridge and connect your wallet by clicking the “Connect Wallet” button at the top right of the page.

  • Select the chain you wish to bridge from by selecting the drop-down menu.

  • Choose the asset you want to deposit.
  • Enter the amount you want to deposit.
  • Allocate allowance for the asset you want to deposit (if you’re depositing non-ETH assets).

  • Review and confirm deposit.

Deposit times vary and are subject to Ethereum Mainnet congestion.

Gas Fees Reminder:

You will need ETH on L1 as gas fees to deposit your tokens from Ethereum Mainnet and $MNT on L2 as gas fees to transact your deposited tokens on Mantle Network.

Once you complete the above steps, you will be greeted with a "Deposit complete" screen confirming that your assets are now available for use across Mantle Ecosystem.

Withdraw from Mantle L2

The withdrawal process from Mantle Network Mainnet is as simple as the deposit process.

  • Head to the Mantle Mainnet Bridge and make sure you are set to bridge from Mantle. Users can click the arrows to switch between depositing onto Mantle and withdrawing from Mantle.
  • Select the amount you wish to withdraw.
  • Select "Withdraw token from L2".

Gas Fees Reminder: You will need $MNT on L2 as gas fees to initiate the withdrawal from Mantle Mainnet and ETH on L1 as gas fees to claim the withdrawal on Ethereum Mainnet.

  • Confirm your understanding of the withdrawal process and the associated wait times, then select "Initiate Withdrawal".

  • Wait 30 minutes, then prove the withdrawal.

After this, users will have to wait 7 days (due to rollup challenge period) to claim their withdrawal.

View Your account and Check Status

There’s a page for you to check the bridging history and status of your deposit, withdrawal or migration transactions on Mainnet.

Select the "History" tab where you'll be able to check the status of both your deposits and withdrawals.

$MNT Bonus

A 1 $MNT bonus will be sent to the users wallet address on Mantle L2 after 1 successful deposit of any token from Ethereum L1 to Mantle L2.

Things to keep in mind:

  • No restriction on deposit token type nor minimum deposit amount
  • The $MNT bonus is limited to ONE per qualifying wallet address — the bonus amount and qualification factors may change in the future
  • Must be using our official Mainnet bridge via https://app.mantle.xyz/bridge
