The exchange says the withdrawal completed. Where are the funds?

At the destination address on the chain the withdrawal used. Paste that address, or the withdrawal transaction hash, and the checker reads it live.

Can an exchange return funds sent to one of its deposit addresses on the wrong chain?

An exchange is able to credit or return such a deposit when it supports the asset on that chain; whether it does is decided on its side. The proof page gives its support team the evidence.

A common mistake

Withdrew from an exchange on the wrong chain

The exchange sent the funds where the withdrawal form said: to your address, on the chain selected there. They are at that address on that chain now.

Where did the funds go?

Paste the address the funds were sent to, or the transaction hash if that is easier. Your browser reads the public chain live and tells you what is there and who is able to move it.

Not sure which? Open the transfer in your wallet or exchange history and copy either the recipient address or the transaction hash.

Check the address

What the checker does here

If the destination is a wallet you hold the key to, the fix is usually to add that chain to the wallet: the funds are already yours to move. The checker confirms the balance and whether the address has code on that chain.

If the destination was itself a deposit address at another exchange, only the exchange that controls it is able to credit or return the funds. The checker matches the address against a small, cited list of public exchange labels and, on a match, prepares support-ticket text with the on-chain evidence and a link to a proof page anyone can re-derive.

If the destination is a contract, the checker reports what its control surface answered and prepares a message to the team that operates it.
