Let’s start with a reality check. 

People lose their funds to centralized platform hacks or account restrictions because they don’t control their money. The biggest risk in crypto isn’t just losing your investment but giving someone custody of your assets,  like putting your Wi-Fi password on a billboard and hoping no one uses it.

In 2022, FTX, one of the largest centralized exchanges, went bankrupt. Over $8 billion worth of user funds vanished because millions of people trusted a centralized entity with their retirement funds. 

The whole point of getting into crypto is to break free from the control of traditional banks, so why would you let anyone else decide how much you can send, how often, or when you can even access your own money?

You need a custodial wallet.

It’s a crypto wallet where you hold the private keys to your funds. Think of a private key as your wallet's secret password that gives you access to your crypto. It’s created using your seed phrase, a special set of words serving as a backup for your wallet. Without the key, you can’t manage your funds, so keeping it safe is important. 

Custodial vs. Non-Custodial Wallets 

The key difference between custodial and non-custodial (self-custodial) wallets lies in who controls the private keys. 

Custodial wallets, the ones where you don't really own your funds, are way easier to use, and they'll be the first wallets that newcomers come across on CEXs.

On the other hand, non-custodial wallets allow you to manage your private keys directly. These keys are provided in a human-readable form called a seed phrase, a series of words that can be used to recover your wallet if needed. Seed phrases are every crypto newbie’s worst nightmare. But the faster you learn to deal with them, the less likely you’ll end up rekt.

Let’s clear something up about wallets. Your wallet doesn’t actually “store” your crypto. All your assets are on the blockchain. A wallet lets you access and manage your blockchain-based assets using your private key.

Types of Self-Custodial Wallets 

Self-custodial wallets are categorized into cold and hot wallets. 

Cold wallets like Trezor and Ledger Nano X, are offline hardware devices that securely store private keys, protecting them from internet-based attacks. They should be used exclusively for storage, avoid using them to approve transactions on dApps. The only actions recommended are sending and receiving crypto to reduce exposure to attacks. 

In contrast, hot wallets are online software wallets, such as MetaMask or Trust Wallet, designed for convenience and frequent use, like everyday transactions, DeFi, or NFTs. While accessible and user-friendly, their internet connection makes them more vulnerable to hacks. 

How to Use a Self-Custodial Wallet 

Ready to not get rekt?

A self-custodial wallet is straightforward, but it requires attention to detail, especially when handling your private keys. 

1. Choose a Wallet Decide whether you need a cold wallet for maximum security or a hot wallet for everyday use. Consider the networks you plan to use; for example, use Rabby or MetaMask for Ethereum-based assets or Phantom for Solana. 

2. Set Up Your Wallet After selecting your wallet, follow the setup instructions. During the setup process, your wallet will generate a recovery phrase (seed phrase). Write it down and store it offline in a secure location, as losing it means losing access to your funds. 

3. Fund Your Wallet Transfer crypto from an exchange or another wallet to start using your wallet. Use the wallet’s unique public address to receive funds. 

4. Send and Receive Cryptocurrency You can send crypto by entering the recipient’s address and confirming the transaction. Always double-check wallet addresses before sending funds. 

5. Interact with Blockchain Applications Cold wallets (e.g., Trezor, Ledger) are meant for secure storage, not for interacting with dApps. Using them for transactions exposes your assets to unnecessary risks, as they are designed to remain offline for maximum security. For DeFi, gaming, and NFTs, always use hot wallets like MetaMask, Rabby, Phantom, or Trust Wallet for safer and more convenient access.

So, ask yourself this question: do you want control or are you fine trusting someone else with your future retirement?
