When entering the world of digital assets, one of the most critical decisions you'll make is how to store your cryptocurrencies. Broadly speaking, there are two main types of crypto wallets: custodial and non-custodial, also known as self-custody wallets. The fundamental difference lies in who controls your private keys—the secret codes that act like passwords to manage your assets.
Both options come with their own set of risks. Using any form of crypto custody means placing trust in the software or hardware you choose. Whether you opt for a custodial service hosted by a centralized exchange or a self-custody wallet, it's essential to select a reputable and trusted provider.
Choosing a self-custody wallet means you take full responsibility for your private keys and, by extension, your assets. This guide will walk you through the entire setup process, best practices, and key considerations to help you get started safely and confidently.
Understanding Custodial vs. Non-Custodial Wallets
The core distinction between custodial and non-custodial wallets boils down to control over private keys:
- Non-custodial (self-custody) wallets: You control your private keys.
- Custodial wallets: A third party, such as a centralized exchange (CEX), controls your private keys on your behalf.
Self-custody wallets store your private keys and provide an interface for managing your crypto, which actually resides on blockchains. These wallets enable you to send and receive cryptocurrencies and interact with decentralized applications (DApps). Since you manage your private keys—with support from a trusted wallet provider—you maintain complete control over your assets.
Custodial wallets, on the other hand, involve a third party holding your private keys and maintaining custody of your crypto. While you can perform basic functions like sending and trading assets through the custodian's platform, you typically cannot connect to DApps. Ultimately, you must trust the third party to safeguard your private keys.
Both types of wallets allow you to view balances and transaction history for your crypto addresses.
Why Use a Self-Custody Wallet and How to Begin
The primary motivation for self-custody is avoiding the need to trust a custodian, such as a CEX, with your private keys. Custodians, like banks, can face bankruptcy, commit fraud, or misuse funds without your consent. Self-custody empowers you to manage your assets independently, with the support of a reliable wallet.
To set up a self-custody wallet, follow these steps.
Note: Most self-custody crypto wallets follow a similar setup process. For detailed technical assistance, refer to your chosen wallet provider's documentation.
Step 1: Know the Different Types of Self-Custody Wallets
Before selecting a wallet, understand the available options. The main categories are software wallets and hardware wallets.
Software Wallets (Hot Wallets)
Software wallets are applications installed on your computer, smartphone, or tablet, or as extensions in your web browser. Often called "hot" wallets, they remain connected to the internet, offering convenience and easy access to your private keys. However, this connectivity makes them more vulnerable to hacking compared to hardware wallets.
Note: Be cautious of "spoofed" browser extensions, which are fraudulent copies designed to steal your information.
Hardware Wallets (Cold Wallets)
Hardware wallets are physical devices, similar to USB drives, that store your private keys offline. This method is known as "cold" storage. These devices securely sign transactions offline and broadcast them once connected to a computer or phone. While they offer enhanced security, they are less convenient due to the need for physical access and connection.
Step 2: Choose a Wallet
There is no universally correct choice between software and hardware wallets—it depends on your preferences and risk tolerance. Many users employ both: software wallets for everyday transactions and hardware wallets for storing larger amounts long-term.
Select a trustworthy provider with a solid reputation. Popular wallets often have higher trustworthiness due to extensive user bases and positive reviews. Always choose wallets with high ratings and numerous user feedback.
Popular Software Wallet Options
MetaMask and Coinbase Wallet are among the most widely used software wallets. However, since these operate as browser extensions, exercise caution. Extensions require significant permissions, making them potential vectors for risk. Attackers sometimes create spoofed versions to defraud users.

Popular Hardware Wallet Options
Ledger and Trezor are leading hardware wallet brands. Both offer verification processes to ensure device authenticity and are trusted by millions of crypto users worldwide.
Browser-Native Option: Brave Wallet
To mitigate extension-related risks, Brave Wallet offers a self-custody solution built directly into the browser. Available on desktop, Android, and iOS, it eliminates the need for downloads and integrates seamlessly with hardware wallets like Ledger and Trezor.
Step 3: Generate or Import a Recovery Phrase
When creating a new wallet, you'll generate a recovery phrase (or seed phrase)—typically a 12- or 24-word sequence. This phrase serves as your wallet's master private key, enabling you to generate new private keys and recover your wallet if your device is lost or damaged.
A recovery phrase is a human-readable version of your master private key, making it easier to record than a long hexadecimal string.
Important:
- You may be asked to re-enter your recovery phrase during setup to verify accuracy. Never share this phrase with anyone.
- To restore an existing wallet or manage previously created addresses, you'll need your recovery phrase.
Step 4: Create or Import Crypto Addresses
Crypto addresses and their private keys are automatically generated when you set up a wallet. You can create additional addresses within your wallet, but each requires a wallet for generation.
You'll need a separate address for each blockchain you use. For example, Brave Wallet automatically creates addresses for Ethereum and Solana.
Each address has its own private key, derived from your master private key. Thus, compromising your recovery phrase exposes all keys created within the wallet (except imported accounts).
Imported accounts are addresses generated in one wallet and added to another. For instance, an address from MetaMask can be managed in Brave Wallet but remains tied to its original recovery phrase.
Step 5: Transfer or Purchase Crypto
Finally, add crypto to your wallet by transferring from a CEX or purchasing directly with fiat currency (if supported). For example, Brave Wallet allows fiat purchases via partners.
When transferring assets:
- Double-check the recipient address.
- Conduct a small test transaction before moving large sums.
- Ensure you're using the correct network (e.g., send ETH only to Ethereum addresses).
