Custodial and Non-Custodial Wallets

Abstract

Non-custodial wallets are a type of cryptocurrency wallet wherein the owner has full control over the private keys and is solely responsible for managing and securing the digital assets that it contains. Unlike custodial wallets, which are managed by third parties, such as exchanges, non-custodial wallets ensure that funds are controlled exclusively by the end user. We characterise the difference between custodial and non-custodial wallets and examine their key features and related risks.
