What is a Custodial Wallet?

A custodial wallet refers to a type of cryptocurrency wallet where the private keys are managed and held by a third-party entity, typically a centralized service provider like an exchange. These wallets allow users to store, send, and receive cryptocurrencies. The primary aspect that makes them stand out is the fact that the user does not have direct control over their private keys. This contrasts with non-custodial wallets where the user retains complete control over their keys. Custodial wallets play a crucial role in the crypto ecosystem, especially for users who prioritize convenience over full control. This article delves deep into the intricacies of custodial wallets, their history, benefits, drawbacks, and much more.

A custodial wallet operates on the premise that the service provider manages the private keys on behalf of the user. Users access their funds using account credentials, such as a username and password. Transactions are facilitated by the service provider, and users typically interact with a user-friendly interface to manage their funds.
