If you need assets on the other chain, Mantle Bridge moves supported tokens such as ETH and MNT between Ethereum and Mantle Network. For a Mantle to Ethereum bridge transfer, use the Mantle Bridge to move your chosen asset. Pay gas, confirm the transfer, and claim the withdrawal on Ethereum when it is ready.
Key points
Start by identifying which network holds your tokens and which network needs them. An Ethereum to Mantle deposit gives you a corresponding balance on Mantle; a withdrawal returns the asset to Ethereum. Bridging moves an asset between networks, while swapping changes one asset into another.
For example, if you hold USDT on Ethereum and want to use USDT on Mantle, check that the route supports your USDT token and shows the Mantle token you expect to receive. A ticker alone is insufficient: tokens with the same name can have different contract addresses or issuers. The Mantle cross-chain bridge depends on a supported mapping between the source asset and its destination representation.
mantlebridge.org is the service for moving supported assets between Ethereum and Mantle Network. Before committing to a route, compare the destination asset, the amount you will receive, and the time until you can use it. A liquidity bridge may pay from tokens it already holds on the destination chain, but its quote can include a provider fee or a different token representation.
Keep the native gas currency available wherever you must sign a transaction. Ethereum transactions use ETH, including an ERC-20 approval, a deposit, or a later withdrawal claim. Transactions on Mantle use native MNT, including a withdrawal or a transfer after your deposit arrives.
The common mistake is depositing ETH or USDT and arriving on Mantle with no MNT. The bridged balance may be visible, but you cannot send or use it until your wallet has MNT for gas. If you plan to bridge MNT to Mantle, check how much native MNT will arrive and reserve some for your next transaction.
Think through the gas you may need:
As an illustrative calculation, an approval using 60,000 gas and a deposit using 180,000 gas would consume 0.0024 ETH together at 10 gwei. Actual gas use and gas prices vary, so check your wallet’s estimates before signing. Sending 250 USDT with zero ETH in the same Ethereum wallet will fail before the deposit, because USDT cannot pay Ethereum gas.
A bridge transfer follows the source transaction, cross-chain processing, and destination receipt in that order. Use this sequence for a deposit or withdrawal, adjusting the gas currency and final claim for the direction you choose.
