How to Resume a Mantle Bridge After Closing Your Browser

One confirmed transaction can outlast the browser session that submitted it. Closing the tab usually stops the interface, not a transaction already recorded on a blockchain, so you can reconnect and check what remains.

The first distinction is whether you signed and submitted a wallet request. A transaction still waiting for your signature has not been sent; one with a transaction hash has been broadcast and can be checked on its source network. The mantle bridge process can involve separate steps, so the first confirmed transaction may not mean the transfer is complete.

What happens to a bridge transfer when you close the browser?

A submitted transaction continues to be processed by the network after you close the browser. The bridge website is an interface for preparing and tracking actions; it does not need to stay open for a signed transaction to be included in a block.

That does not mean every open bridge action continues. If you closed the page before signing in your wallet, there may be no transaction to resume. If you signed an ERC-20 token approval but did not submit the deposit, only the approval was sent: permission for a contract to spend tokens is separate from moving those tokens.

Bridge transfers also cross networks. A deposit from Ethereum to Mantle starts with a transaction on Ethereum, while a withdrawal starts on Mantle and may need a later claim on Ethereum. Each step has its own status and may need a separate wallet signature and gas fee.

How can you find the transfer’s current status?

You can find it by reconnecting the wallet that submitted it and checking the transaction hash on the relevant network. The hash is a public identifier for a transaction, and an explorer can show whether it is pending, confirmed, failed or still awaiting a later bridge action.

Start with the wallet’s activity list or the bridge’s history view. If the transfer is missing there, look up the hash directly on the explorer for the source network. Check the sending address and destination address carefully; two wallets can look similar, and the destination may not be the account you expect.

• No hash and no wallet signature: the request was probably never submitted. Reopen the bridge and check the details before starting.
• Approval confirmed: the token allowance may be set, but the deposit still needs its own transaction.
• Deposit confirmed on the source chain: check the bridge history and destination balance for the message or token arrival.
• Withdrawal started on Mantle: check whether it is ready for a separate claim on Ethereum.

A wallet can also show a transaction as pending while the explorer shows the same status. In that case, closing and reopening the page will not speed up network processing. If the explorer marks it failed, check the failure details before trying again; submitting another transaction without understanding the first can create a duplicate transfer.

How do you continue the transfer safely?

Continue from the latest confirmed step, using the same wallet address and the official bridge interface. The right next action depends on the transaction status, not on how far the progress animation had moved before the browser closed.

1. Reconnect the wallet that made the original transaction. Confirm its address and select the network where the next action must happen.
2. Open the bridge history and compare the listed status with the transaction hash on the source-chain explorer.
3. If an approval is confirmed but no deposit appears, submit the deposit only after checking the asset, amount and receiving address.
4. If a withdrawal is waiting for its final step, follow the bridge’s claim instructions when it becomes ready. Check that you have the required gas token on the network where you must sign.

Review every wallet prompt before signing. A transaction’s network and destination matter: a signature on Mantle cannot pay the gas for an Ethereum claim, and a balance on one network does not automatically fund activity on another. Never share your recovery phrase or private key to “restore” a bridge session; reconnecting a wallet should require the wallet’s normal connection flow, not disclosure of secret credentials.

If the bridge interface and explorer disagree, use the transaction hash and network record to understand what has actually been submitted, then give the interface time to refresh. Keep the hash until the destination balance or final claim is confirmed. A browser closure is usually a break in your view of the transfer, not a reversal of its on-chain steps.
