In plain English
What Custodial wallet means
With a custodial wallet, you access your crypto through a platform such as an exchange or app, and that platform manages the keys needed to move the funds. You may log in with a password, but the platform—not you—controls the underlying wallet. If the provider freezes access or has an outage, you can lose the ability to transact until it restores service.
Why it matters
The custody model determines who can authorize transfers, who can recover access, and where operational risk sits. It also affects how users should think about account recovery, platform failures, and counterparty exposure. A custodial wallet is not the same as personal possession of a private key.
Example
A user deposits 0.5 BTC into an exchange account. The exchange records the balance internally and holds the keys that can move the coins. The user can place a withdrawal request, but the exchange signs and broadcasts the on-chain transfer. This is simplified for illustration.
Quick answers
Common questions
Is a custodial wallet the same as an exchange account?+
Often, yes. Many exchanges provide custodial wallet services, meaning they control the keys while you see balances and request transfers through the platform.
Can I recover access if I lose my password?+
Usually yes, because the provider manages account recovery. But recovery depends on the platform’s policies, not your private key.
