When your chosen token has no direct route, use a bridge only if it supports your exact source chain, token, and destination. A missing route can mean the token is unsupported there, even when both chains appear in a bridge’s network list.
How can you tell if a bridge route fits?
Check the full route in the transfer screen: source network, token, destination network, and the token you will receive. A route between two chains does not guarantee that every token can travel between them.
For example, if a token route from Chain A to Chain B is offered, check the destination token’s name and address before sending. If it is a wrapped token, it represents an asset held or issued elsewhere; it may not be interchangeable with the destination chain’s native version.
When comparing routes, I would choose a clearly named destination asset over a shorter path with an unclear token. Use wormhole bridge transfers as a concrete example: check the offered token and route details before approving, rather than assuming the same ticker means the same asset.
What happens after you start the transfer?
A bridge transfer starts with a transaction on the source chain. The bridge’s contract locks or burns the tokens and records a message for the destination chain.
In Wormhole’s Token Bridge, Guardians verify and sign that message as a VAA, or verifiable action approval. The destination contract checks that proof, then releases the original tokens or creates a wrapped version for you.
Some routes ask you to submit the proof in a second transaction. Others use a relayer, a service that submits it for you. Wormhole’s Token Bridge specification describes this source-message-proof-destination flow; the Ethereum ERC-20 standard defines the common token format used by many supported assets.
This creates a useful contrast: if a route is fully relayed, you may confirm the source transaction and wait; if it is manual, you may need to claim the tokens yourself. Either way, the destination wallet needs the correct network selected, and a manual claim may require that chain’s gas token to pay its transaction fee.
What should you check before approving?
Compare the amount you send with the amount expected to arrive, and read the quote for network gas, bridge fees, and any relayer charge. These costs vary by chain, route, and network demand; the destination amount can also be lower after fees.
Then check the recipient address, destination network, and token identity. A correct address on the wrong chain can leave you unable to use the funds, while a token with the right ticker but a different contract address may not be the asset you intended.
If the direct route is absent, check whether another supported token or route reaches the destination, but only use an option whose final asset you understand. Avoid improvising a chain-by-chain detour unless each leg is supported and you can cover its fees.
After sending, keep the transaction record and follow its status until the destination balance appears; a source confirmation alone does not prove delivery. Before a large transfer, try a small amount first, and keep enough destination gas for any manual claim.
