What Is a Self-Custodial Wallet (Non-Custodial Wallet)?

A self-custodial wallet, also known as a non-custodial wallet, is a type of cryptocurrency wallet that allows users to manage their private keys and have direct control over funds stored on a blockchain network. TL;DR Self-custodial wallets allow users complete control over their private keys and crypto assets. Setting up a self-custodial wallet does not require the user to share any personal information with a third party.

Today, this type of wallet may not be a good choice for new users who don’t understand asymmetric cryptography’s role in blockchain transactions.
