Why bridged crypto can arrive but stay stuck without gas

Your bridged tokens can arrive in your wallet and still be unusable if you lack the destination chain’s gas token. Gas is the fee paid to make transactions on a blockchain, and a token balance does not pay that fee unless it is the network’s native token.

Why can I see my bridge balance but not move it?

The bridge transfer and your next transaction are separate steps. A bridge moves an asset between networks; sending, swapping or approving that asset later requires a new transaction on the destination network. For example, a wallet holding a bridged token on a network that uses ETH for fees needs some ETH on that same network to make a swap.

This is why a balance can look healthy while the wallet says the transaction cannot be sent. The tokens may be in your address, but the wallet cannot pay the fee. Routes can handle this differently: some include destination gas or cover a delivery step, while others send only the bridged asset. For a closer look at how Mantle Bridge’s canonical and liquidity routes differ, see the fuller route comparison.

How do I tell whether the transfer arrived?

Check the transaction status before sending more funds. If the bridge marks the transfer complete, switch your wallet to the destination network and check the address there. You may need to add the token to the wallet’s display; that changes what the wallet shows, not where the funds are held.

If the transfer is still pending, adding gas on the destination chain will not finish the bridge. Check the bridge’s status page or transaction record using the source transaction hash. Some routes need extra time or a separate claim step. Do not repeat the transfer until you know what happened to the first one.

What can I do if I have no gas on the destination chain?

Once the tokens have arrived, you need a small amount of the destination chain’s native gas token to make another transaction. The right amount depends on the network and the action, so check the wallet’s fee estimate before moving funds.

• Send a small amount of the correct gas token to the same wallet address on the destination network.
• Use a bridge route that offers a gas top-up or lets you pay the destination fee another way, if available. It may cost extra.
• If the route sends gas with the transfer, check its settings and receipt to see whether that option was selected.

Before sending gas, confirm the network and address in your wallet. A token with the same name on another network may not pay this chain’s fees. If you cannot get gas directly, a trusted exchange or another wallet may be an option, but check its withdrawal network first.

The key distinction is simple: a completed bridge transfer can leave the asset in place while blocking what you want to do next. Confirm the destination balance, then fund that network’s gas token before trying to move or swap the funds.
