- Custody risk covers failure, hacks, freezes, and commingled funds.
- Your balance is an IOU, not a claim on coins.

A cryptocurrency exchange lets people trade crypto for dollars or other digital assets. Buying there leaves your coins in an account the exchange controls.
How exchange custody actually works
When you leave coins on an exchange, the exchange holds the private keys. You log in with a username and password, so your balance is a promise from the company, not a claim on particular coins.
- The exchange holds the private keys.
- Your balance is an IOU.
- The exchange decides when withdrawals process.
- A login, not a seed phrase, restores access.
Main risks of exchange custody
Most custody risk comes from the exchange itself. It can run short of money, lose coins to attackers, freeze withdrawals, or mix customer funds with its own. US exchange balances are usually not FDIC-insured the way bank deposits are.
Exchange custody versus self-custody
Self-custody means you hold the private keys in a wallet you control. You also carry the loss risk, because coins in a wallet you cannot access are gone permanently.
How to check an exchange's custody
Public documents show how an exchange says it holds customer assets. The terms of service describe what you own, and the withdrawal policy sets the limits you face.
