The answer
If you have already withdrawn assets to a self-custodial wallet and control the keys, an exchange shutdown does not normally remove those on-chain assets.
What to do next
Confirm final settlement to an address you control and maintain verified offline recovery backups. Assets still left in exchange custody are subject to that provider’s situation.

Frequently asked questions
