How to Check Your First Mantle Bridge Deposit

To check your first Mantle Bridge deposit, confirm the source transaction on Ethereum, then look for the matching asset in the destination wallet on Mantle. The two checks matter because a successful Ethereum transaction shows that the deposit was sent; it does not, by itself, prove that the balance is visible in the wallet you expect.

How do I find the deposit transaction?

Start with the transaction hash in your wallet’s activity list or the bridge’s transfer history. Open it in an Ethereum block explorer, a site that displays on-chain transactions, and check that its status says “Success.” Make sure you opened the deposit transaction, not a token approval: an approval gives the bridge permission to use a token, but does not send it. A separate guide to the gas costs behind a Mantle Bridge deposit explains why a token deposit may involve more than one Ethereum transaction.

Check the transaction details against your intended transfer. Confirm the token and amount, and look for the bridge deposit or message event in the transaction record. If the transaction says “Pending,” it has not yet been confirmed on Ethereum. If it failed, the asset was not deposited through that transaction; use the wallet or explorer details to see whether it was an approval or the deposit itself.

How can I confirm the funds arrived on Mantle?

Search the receiving address on a Mantle block explorer, then check its token transfers and current balance. The receiving address is often your connected wallet, but compare the full address shown in the bridge record with the address you meant to use. A copied address can be wrong even when the source transaction succeeded.

The bridge maps the deposited asset to a balance on Mantle. Check the asset name and token details, not just the number shown in the wallet: the wallet may not display a token until you add or select it. Also make sure the wallet is set to Mantle. A balance on one network will not appear in the same way while you are viewing another.

What should I do if the balance is missing?

First, check the bridge’s transfer history for a destination status or link to a Mantle transaction. If it shows that processing is still underway, give it time and check again; do not submit another deposit just because the wallet has not refreshed. Then work through these checks:

• Confirm the Ethereum transaction is successful and is the deposit, not only an approval.
• Compare the destination address in the bridge record with the address open in your wallet.
• Switch the wallet to Mantle and check the token balance or transfer history in a Mantle explorer.
• Check whether the wallet needs the token added to display its balance.

If the source deposit is confirmed but the bridge record shows an error or no matching Mantle transfer, keep the transaction hash and contact the bridge’s support through a channel linked from its official site. Never share your recovery phrase or private key to resolve a transfer issue.

The useful distinction is simple: Ethereum confirms that you sent the deposit; the Mantle-side record and wallet balance show whether it reached the destination. Check both before deciding that a transfer failed.
