Why a bridged token cannot pay your gas on arrival
A bridge can deliver a token without delivering the destination chain’s gas asset: understand the fee payer, exceptions and what to check before sending.

Why can your bridged token arrive but leave you unable to move it? Because the destination chain charges transaction fees in its gas asset, and a bridge transfer does not usually include that asset. The token balance is there; your wallet simply cannot pay to approve, swap or send it.
Why doesn’t the bridged token cover the fee?
On most smart contract chains, the protocol checks your balance of the designated gas asset when it processes a transaction. An ERC-20 token’s contract tracks who owns that token, but it does not change the chain’s fee rules. So a bridged stablecoin cannot pay a fee charged in the destination chain’s native token.
A bridge typically locks or burns an asset on one chain and releases or mints a corresponding representation on another. That movement does not automatically top up your destination gas balance. The mantle bridge is a useful example to examine when you want the details of how deposits, costs and withdrawals fit together.
What can you do with the token once it arrives?
You can hold it, but a wallet transaction that changes its onchain state generally needs gas. That includes sending the token, approving a decentralised application to spend it, or swapping it for the gas asset. A displayed balance confirms receipt; it does not confirm that you can transact.
Check these details before bridging, especially if you are sending nearly all your funds:
- Which asset pays gas on the destination network?
- Does the bridge quote include a destination gas top-up, or only the transfer?
- Will the destination token be a native asset or a token contract representation?
Are there cases where you can pay another way?
Yes, but they depend on the chain or service. Some wallets and applications support a relayer, paymaster or other sponsored transaction that accepts a different token or covers the fee for you. That support is an added transaction service, not a property every bridged token has.
If you are short on gas, the usual fix is to send a small amount of the destination chain’s gas asset to the same wallet, or use a supported sponsored transaction. Check the network name and token contract before acting, since similarly named assets can exist on different chains. Before you bridge, watch the wallet’s estimated destination gas requirement and make sure you will have enough to use the funds after they arrive.
