What Is a Self-Custody Wallet?

A self-custody wallet, also called a non-custodial or Web3 wallet, is a cryptocurrency wallet that holds your private keys, giving you full control over stored digital assets like Bitcoin or Ethereum. Self-custody wallets enable peer-to-peer (P2P) crypto transactions and can connect directly with smart contracts, giving access to DeFi applications.

Self-custody wallets, unlike those from centralized exchanges, keep private keys solely with the user and often don’t require registration or KYC verification.

🍒 Crypto Investing for Beginners in 5 Steps

Crypto Hot Wallet vs. Cold Wallet

Self-custody wallets, also called decentralized wallets, safeguard private keys. There are two primary types of self-custody wallets:

  • Hot wallets are connected to the Internet and can be used for regular on-chain transactions, such as interacting with DeFi apps or sending payments. They come in the form of browser extensions, desktop apps, or mobile apps. Centralized exchange wallets also fall into the category of hot wallets, but they don’t provide self-custody, so we’re not discussing them in this article.

  • Cold wallets store crypto funds entirely offline. They may come in the form of hardware or even paper. Hardware wallets store digital assets offline, but they can easily connect to the Internet through a USB port. Still, cold wallets are more suitable for long-term storage. 

Both wallet types offer enhanced security over custodial wallet apps by storing private keys, with cold wallets generally being more secure.

Let’s now compare some advantages and disadvantages of hot wallets.

Hot Wallet Pros Hot Wallet Cons
User-friendly desktop/mobile apps. Exposure to online security threats.

Features like in-app swaps and staking. Risk of smart contract vulnerabilities.
