In plain English
What Crypto custody means
Custody is about control, not just storage. If a third party holds the keys, the setup is custodial. If the owner controls the keys directly, it is self-custody or non-custodial. The legal and operational details can differ by provider and jurisdiction, but the basic question is always who can authorize transfers.
Why it matters
Custody determines where key-management risk sits, how recovery works, and who may be able to move the assets in a failure, fraud, or insolvency scenario. It is one of the first distinctions to understand before using any crypto service.
Example
A customer leaves crypto on an exchange account. The exchange controls the wallet keys, so the customer has custodial exposure to the service’s security and operational practices. If the customer withdraws to a personal wallet, the customer becomes responsible for key protection.
Quick answers
Common questions
Does custody mean the asset is fully safe?+
No. Custody only describes who controls access. It does not eliminate theft, operational, legal, or market risk.
Is self-custody always better?+
Not always. It gives more direct control, but it also puts backup and security responsibility on the owner.
