Custodial vs non-custodial wallets: what's the difference?

Every crypto wallet answers one question, whether it says so or not: who holds the keys? The answer decides who can move your money, who can freeze it and what happens if something goes wrong.

There are two kinds of wallet. A custodial wallet is one where a company holds the keys for you. A non-custodial wallet, also called a self-custody wallet, is one where you hold them yourself.

First, what is a "key"?

A crypto wallet doesn't store coins the way a purse stores cash. Your balance lives on the blockchain. What the wallet stores is a private key: a secret that proves you're allowed to move that balance. Whoever has the key can sign payments. Nobody else can.

Most wallets also give you a recovery phrase, usually 12 or 24 words, that can rebuild the key on a new device. Treat it like the key itself.

Custodial wallets

When you buy crypto on an exchange and leave it there, you're using a custodial wallet. The exchange holds the keys and keeps a record of how much belongs to you.

What's good about it

• Familiar sign-in with email and password
• If you forget your password, support can help you back in
• Easy to trade and to cash out to a bank

What to watch out for

• The company can freeze, limit or delay withdrawals
• If the company is hacked or fails, your funds are at risk
• You depend on its rules, fees and opening hours

Non-custodial (self-custody) wallets

With a non-custodial wallet, the key is created and stored on your own device. The company that makes the app never sees it.

What's good about it

• Only you can approve a payment
• Nobody can freeze or reverse your funds
• Your money doesn't depend on any one company staying in business

What to watch out for

• If you lose your phone and your recovery phrase, nobody can restore your wallet
• Many self-custody wallets are hard to use: long addresses, separate gas tokens and no name check before you pay
• Mistakes can't be undone by a support team

Custodial wallets trade control for convenience. Self-custody gives you control, and traditionally asked you to give up convenience.

Side by side

Which one should you use?

Many people use both. A custodial account can make sense for trading or for moving between crypto and your local currency. A self-custody wallet makes sense for money you want to hold, send and receive without asking anyone's permission.

Ask yourself:

1. Would it be a problem if this money were frozen for a week? If yes, self-custody gives you more control.
2. Will I keep my recovery phrase safe, offline and private? If not, start there before moving larger amounts.
3. Am I comfortable checking addresses and networks myself? If not, choose a wallet that does more of the checking for you.

Where BetaPay fits

BetaPay is a non-custodial wallet built to feel like a payment app. Your keys are created and stored on your phone, and every payment is signed there and approved with your PIN or fingerprint. BetaPay never holds your funds and can't move them.

What we add is the part self-custody has been missing: a 10-digit number instead of a 42-character address, a typo check before lookup, and the owner's name shown before you pay. You get control without having to become an expert.

Keeping a self-custody wallet safe

• Write your recovery phrase on paper and store it somewhere private. Don't photograph it or keep it in a notes app.
• No real support agent will ever ask for your recovery phrase or PIN.
• Turn on your phone's screen lock and use biometric approval where your wallet offers it.
• Check the recipient before every payment, and send a small test to new contacts.
