What is a crypto wallet?

Key takeaways:

Crypto wallets are software tools that secure your public & private keys and serve as your digital identity on Web3.

There are two types of crypto wallets: custodial (or exchange) wallets that delegate ownership of your funds & self-custodial wallets (Phantom) that let you own your assets.

Phantom Wallet provides a sleek, user-friendly, and secure interface for managing your crypto and tokens across Ethereum, Polygon, and Solana blockchains.

Most crypto beginners start by opening an account on a crypto exchange like Coinbase. Although exchanges have become the go-to entry point for newcomers to web3, it's crucial to recognize the inherent risks associated with exchange wallets, as they exercise control over your assets.

Opting for self-custody wallets like Phantom presents significant benefits, granting you complete authority over your crypto holdings and enabling seamless access to the vast landscape of web3 applications.

In this article, we'll explain what a crypto wallet is, how it works, and how you can use it to protect your digital assets.

What is a crypto wallet?

Crypto wallets are software tools that enable users to securely access, manage, and interact with their cryptocurrencies by storing their cryptographic keys. These cryptographic keys (also known as public and private keys) allow users to access digital assets on the blockchain.

How do crypto wallets work?

Contrary to popular opinion, crypto wallets don’t actually “store your crypto.” Instead, they store your public and private keys, which let you access your crypto assets.

When you sign up for a crypto wallet, two keys are created: a public key and a private key. Think of public keys as a mailbox where anyone can email you if they have its address. In contrast, private keys act as the “password” to this mailbox, and can access all stored emails or change its settings.

Here’s an example of a public key on your Phantom wallet:

Public Wallet Keys

A public key is a long sequence of random letters and numbers, around 26-42 characters long, and is derived from the private key.

A private key on Ethereum is made of 64 characters. Your Phantom wallet stores your private key, and references it when you sign any transactions.

When setting up a new wallet, you’ll be given a secret recovery phrase, which is your wallet’s private key in a human-readable format. Your recovery phrase is what gives you access to, and control of, your account, so be sure to keep it safe. The length of this secret recovery phrase depends on the chain, but is usually about 12 to 24 random words.
