Custodial Wallet

A custodial wallet is a service where a third party, such as an exchange or a specialized firm, holds the private keys and manages the assets on behalf of the user. The user does not have direct control over the underlying blockchain address, but rather interacts with the provider's internal interface.

This model provides convenience, as users can recover access if they lose their credentials and can often benefit from faster internal transfers. However, it introduces counterparty risk, as the user is reliant on the custodian's security and solvency.

If the custodian is compromised or goes bankrupt, the user may lose access to their assets. This is the opposite of a non-custodial wallet, where the user retains sole control of their private keys.

The custodial model is widely used by institutional investors and retail users who prefer a managed service experience over the technical complexity of self-custody.
