Web3 Wallets Explained:
Everything You Need to Know About Crypto Wallets
Learn all about web3 wallets, the different types available, and how to get started with the most popular options. This guide will help you navigate the world of web3 wallets.
Web3 wallets are your key to accessing the blockchain. They allow you to interact with decentralized apps, store digital assets like NFTs and cryptocurrencies, and more.
In this post, we’ll break down what web3 wallets are, the types of wallets out there, and why they matter. We’ll also explain how to choose the right wallet for your needs or those of your users.
What is a Web3 Wallet?
A web3 wallet, also known as a crypto wallet, is a digital or physical device that stores your private keys. These private keys are used to access and manage cryptocurrency and blockchain-based assets like NFTs.
Your private key is a unique code generated specifically for your wallet. It is essential for accessing your funds and digital assets. Without it, you can’t transfer or access anything stored in the wallet.
Web3 wallets also support digital identity. They provide users with a pair of cryptographic keys: a private key and a public key. These keys prove ownership and control of digital assets.
What Are Private Keys and Public Keys in Web3 Wallets?
A private key is a secret code that proves ownership of your digital assets. It is used to sign transactions sent to the blockchain. Only you, the owner of the assets, should know this key.
A public key is used to verify that a transaction was signed by the rightful owner. It can be shared publicly and is used to confirm the authenticity of transactions.
How Do Web3 Wallets Work?
When you create a web3 wallet on the Polygon network, you are provided with a unique private key. This private key confirms your ownership of the digital assets stored in that wallet. A corresponding public key is then generated, which others can use to verify your transactions. The combination of the private and public keys ensures secure and decentralized ownership of your assets.
Your wallet also generates a unique address, referred to as a “public address.” This public address is derived from your public key and can be shared with others to receive digital assets. Additionally, this address can be linked to a decentralized name service, like Polygon Name Service (PNS). This makes it easier for others to interact with your wallet. For instance, on the Polygon network, you can register a .polygon domain to your wallet. This allows others to send digital assets to your .polygon domain, rather than using a complex string of characters.
What Are the Different Types of Web3 Wallets?
Web3 wallets come in many forms, offering different levels of access and security based on your needs. Here’s a breakdown of the most common types:
Hot Wallets vs. Cold Wallets
Hot Wallets (Software Wallets):A hot wallet is connected to the internet, making it easy to access and manage your funds. However, this also makes it more vulnerable to security threats like hacking. Hot wallets are best for storing small amounts of cryptocurrency that you frequently trade or spend. These wallets can be either desktop or mobile, and some can be accessed on both.
Desktop Wallets:
Desktop wallets are installed on your computer or laptop. These wallets let you store, manage, and trade cryptocurrency directly from your desktop. They can either be software-based (where you download the wallet app) or web-based (accessed via a browser). Desktop wallets are more secure than online wallets but less secure than hardware wallets due to their internet connection.
Mobile Wallets:
Mobile wallets are designed for use on smartphones or tablets. They let you manage your cryptocurrency on the go. Like desktop wallets, they can be software-based (downloaded from an app store) or web-based (accessed via a mobile browser). Mobile wallets offer convenience but are considered less secure than hardware wallets because they are connected to the internet.
Examples of Hot Wallets:
- Coinbase Wallet (different from the custodial Coinbase Exchange)
- MetaMask
- Phantom
- Rainbow Wallet
- Trust Wallet
- Frame Wallet
- Glow Wallet
Cold Wallets (Hardware Wallets):
Cold wallets, also known as cold storage wallets, are offline wallets that provide a high level of security. Since they aren’t connected to the internet, they are much harder for hackers to access. Cold wallets are best for long-term storage of large amounts of cryptocurrency. Typically, cold wallets are hardware devices like USB drives that securely store your private keys. While they offer excellent security, they require physical storage and are less convenient for frequent transactions.
Examples of Cold Wallets:
Non-Custodial Wallets vs. Custodial Wallets
Non-Custodial Wallets:
Non-custodial wallets give you full control over your funds since you hold the private keys. This means that no third party, including the wallet provider, has access to your assets. You are solely responsible for the security of your funds. These wallets can be software-based (desktop, mobile, web) or hardware wallets. Non-custodial wallets are considered more secure because they eliminate the risk of third-party breaches.
Examples of Non-Custodial Wallets:
- Coinbase Wallet (different from the custodial Coinbase Exchange)
- MetaMask
- Phantom
- Rainbow Wallet
Custodial Wallets:
In a custodial wallet, a third party, such as an exchange, holds and controls your private keys on your behalf. This means you don’t have full control over your funds, and the third party can access them. While this reduces your responsibility for security, it also means that your funds depend on the security of the custodian. Custodial wallets are often offered by exchanges or companies that handle buying, selling, and trading of cryptocurrencies.
Examples of Custodial Wallets:
- Coinbase Exchange (different from the non-custodial Coinbase Wallet)
- Kraken Exchange
- Reddit Vault
Email Wallets:
Email wallets are a type of custodial wallet that allows users to sign up, log in, and create web3 wallets using their email addresses. These wallets make it easy for users to start using blockchain-based apps without any prior experience with crypto. Many companies prefer email wallets for onboarding users who are new to web3. These wallets handle security and simplify blockchain complexity for the user.
Examples of Email Wallets:
Smart Contract Wallets:
Most traditional web3 wallets are controlled by private keys, also known as Externally Owned Accounts (EOAs). However, smart contract wallets are different. They are built on smart contracts, allowing for additional security features like social recovery, transfer limits, and account freezing. These added features are made possible through a concept called account abstraction.
Multisig Wallets:
Multisig wallets are smart contract wallets that require more than one signature to authorize transactions. This adds an extra layer of security because multiple parties (like friends, family, or coworkers) must approve the transaction. This setup makes it harder for hackers to access your funds, as they would need to compromise several accounts. While multisig wallets offer better security, the need for multiple approvals can slow down transactions.
Examples of Smart Contract and Multisig Wallets:
MPC Wallets (Multi-Party Computation):
MPC wallets take security a step further by replacing a private key with multiple independently created “secret shares.” These shares allow for a safe, self-custodial wallet option without the need to worry about losing a single private key or seed phrase.
Examples of MPC Wallets:

Conclusion: Which Web3 Wallet is Best for You?
The best web3 wallet for you depends on your specific needs:
- Maximum Security and Long-Term Storage: If you need a wallet for long-term storage of large amounts of cryptocurrency, a hardware or cold wallet is ideal. Examples include Ledger and Trezor.
- Convenience and Accessibility: If you need a wallet that’s easy to use and accessible from anywhere, a software or hot wallet for both mobile and desktop might be best. Consider options like Coinbase Wallet, MetaMask, Phantom, and Rainbow Wallet.
- Enhanced Security for Organizations: For organizations or advanced use cases requiring extra security, smart contract wallets and multisigs offer additional protection.
- Simple Onboarding: For companies looking to onboard users who are new to web3, email wallets like Magic are a great choice.
Ultimately, the right web3 wallet for you depends on your needs, the level of security you require, and how much control you want over your digital assets. Consider how much you trust the wallet provider, whether the wallet is open-source, and the security track record before making your choice.
We hope this guide has helped you understand the different types of web3 wallets, their uses, and which ones might be best for your needs.
