What if I deposit a coin that is not listed?
Do not. Only markets you can open in Deposit are credit-able. Unlisted tokens are typically lost.
The hard line
Only assets shown on Markets / Deposit can be credited. Sending an airdropped meme token, a wrong ERC-20, or “USDT” on a chain we do not list is treated as an unsupported inbound.
Recovery, if it is possible at all, is manual, slow, and sometimes impossible (smart-contract wrapping, wrong chain, tiny amounts vs cost). Do not plan on it.
Before you click send
If the asset is not in the Deposit dropdown, stop. Convert on the sending venue to a listed asset, then deposit that.
