Overview

Web3 wallets have become essential for anyone dealing with cryptocurrencies or blockchain-based applications. They allow users to store, manage, and transfer digital assets securely. With the rise of decentralized applications (dApps), the need for Web3 wallets has increased. In this guide, we will explore what Web3 wallets are, the different types available, and how to keep them secure.

What are Web3 Wallets?

Web3 wallets are digital wallets designed for interacting with Web3 applications, which are decentralized applications built on blockchain technology. They enable users to store and manage their digital assets, such as cryptocurrencies, NFTs, and other digital tokens.

Types of Web3 Wallets

There are three main types of Web3 wallets: non-custodial, custodial, and smart contract wallets.

Non-custodial Wallets

Non-custodial (aka, self-custody) wallets, also known as self-custody wallets, rely on a public and private key pair to provide users with full control over their assets. A public key is a unique identifier used to receive cryptocurrency or other assets on the network. It is generated from a corresponding private key, which is a long and complex number the user should keep secret. The private key is used to sign transactions sent on the blockchain, ensuring that only the private key owner can access and control the associated assets. A good example of a public key is the address to your house. Anybody can know it or look it up, whereas you can think of the private key as the key to that house. You would want to keep that private from everybody.

It is crucial to keep the private key safe and secure because losing access to it will result in the loss of access to the assets. Non-custodial wallets can be stored in browser extensions or mobile apps and are classified as hot wallets since they are connected to the internet. However, non-custodial wallets can also be stored in physical devices (e.g., Ledger, Trezor) and would then be considered a cold wallet since it has no tech connectivity and stays offline.

Custodial Wallets

Custodial wallets, on the other hand, are wallets where a third party, such as an exchange (e.g., Coinbase), manages the private keys on behalf of the user. These wallets generally require KYC (know-your-customer) and use the same type of recoverability features similar to your email provider. However, this comes with the requirement of trusting the third party with their private keys and assets. Additionally, these wallets may offer the same features that non-custodial wallets provide (i.e., interacting with smart contracts).

Smart Contract Wallets

Smart contract wallets are managed by a smart contract on a blockchain network. On Solana, these smart contracts are referred to as programs so we'll be using these terms interchangeably. These wallets are controlled by the logic outlined in the smart contract, which could require multiple signatures, effectively increasing security by providing a level of redundancy. Recoverability is another feature smart contract wallets offer. Users can use any arbitrary logic in the smart contract wallet to allow the recoverability of funds (e.g., two-factor authentication). Smart contract wallets also support batching transactions together (e.g., approve and transfer a token). These wallets are ideal for all entities, including individual users, businesses, or organizations that require multiple parties to approve transactions.

Web3 Wallets: Which fits you?

The type of Web3 wallet that fits you depends on your level of expertise, the amount of control you want over your assets, and your trust in third parties. Non-custodial wallets are recommended for users who want complete control over their assets. Custodial wallets, on the other hand, are better suited for users who are new to the space and want a simple way to manage their assets. Smart contract wallets are ideal for businesses or organizations that require multiple parties to approve transactions.

Keeping your Wallet Secure

Web3 wallets hold valuable digital assets and are a target for hackers. To keep your wallet secure, here are some best practices to follow:

• Keep your private keys safe: Your private keys are the key to your wallet. Store them in a secure location, and never share them with anyone.
• Use two-factor authentication (2FA): 2FA adds an extra layer of security to your wallet. Enable it whenever possible. Note this is mostly geared toward Custodial wallets.
• Keep your software up to date: Ensure your wallet software is always up to date, as updates often include security fixes.
• Use a hardware wallet: Hardware wallets are physical devices that store your private keys offline. They are considered the most secure way to store your digital assets.
• Beware of phishing attacks: Be wary of unsolicited emails or messages asking for your private keys or personal information.

By following these best practices, you can significantly reduce the risk of losing your digital assets to hackers. We also highly recommend reading this QuickNode guide - An Introduction to Crypto Wallets and How to Keep Them Secure for additional tips on keeping your wallet secure.
