Custodial vs Non-Custodial Wallet: What Is the Difference?
Key points
- Whoever holds the private keys controls the crypto.
- Custodial means a company holds the keys; non-custodial means you do.
- Crypto held on an exchange is not covered like a bank deposit.
- Non-custodial storage only works if your seed phrase is stored offline and safely.
What is a custodial wallet?
When you buy crypto on an exchange and leave it there, the exchange holds the private keys and records your balance in its own system. That is a custodial arrangement. It is convenient: you log in with a password and two-factor authentication, and if you forget your password the exchange can help you recover the account.
The trade-off is trust. Ben Simpson points out in his beginner lesson on YouTube that crypto sitting on an exchange is not insured like money in a bank, and that people have lost funds in the past when exchanges were hacked or collapsed. In Australia, the Financial Claims Scheme protects deposits at banks and other authorised deposit-taking institutions, not crypto held with an exchange.
What is a non-custodial wallet?
A non-custodial wallet gives you the private keys, usually backed up as a seed phrase of 12 or 24 words. Software wallets on your phone or computer can be non-custodial, and hardware wallets, small devices that keep your keys offline, are the common choice for long term storage. Nobody can freeze or lose your coins on your behalf, but nobody can recover them for you either if the seed phrase is lost or stolen.
Custodial vs non-custodial at a glance
| Custodial | Non-custodial | |
|---|---|---|
| Who holds the keys | The exchange or provider | You |
| Account recovery | Possible through the provider | Only with your seed phrase |
| Main risk | Provider failure, hack or account freeze | Losing or exposing your seed phrase |
| Tends to suit | Small balances you trade or are about to sell | Long term holdings you rarely move |
Hot wallets and cold wallets
A second way to describe wallets is hot or cold. A hot wallet is connected to the internet, such as an exchange account or a phone app. A cold wallet keeps the keys offline, such as a hardware wallet. Many long term investors use both: a small hot balance for buying and selling, and cold storage for the core of the portfolio. Our lesson on storing crypto in a hardware wallet shows how the setup works.
Simple safety habits for either option
- Use a unique, strong password and app-based two-factor authentication on every exchange account.
- Write your seed phrase on paper or metal and keep it offline. Ben has shared the story of a client who saved a seed phrase in a cloud drive, deleted it, and still lost funds because the file sat in the recently deleted folder.
- Send a small test amount before any large transfer, and check the full address after pasting it.
- Use exchanges registered with AUSTRAC as digital currency exchange providers.
Which should you choose?
It depends on how much you hold and how often you move it. Many investors keep a working balance on a well-known exchange and move long term holdings to a hardware wallet once the amount would hurt to lose. Whichever you choose, write down where everything is held and how your family could access it. Our guide to what happens to your crypto when you die explains why that matters.
Frequently asked questions
Is crypto on an exchange insured in Australia?
Generally no. The Financial Claims Scheme covers deposits with banks and other authorised deposit-taking institutions, not crypto held on an exchange. If an exchange fails, getting your crypto back depends on that business and any legal process that follows.
What happens if I lose my seed phrase?
With a non-custodial wallet, the seed phrase is the backup of your private keys. If you lose it and the device fails, nobody can restore your access. If someone else finds it, they can move your crypto, so keep it offline and private.
Is a hardware wallet custodial or non-custodial?
A hardware wallet is non-custodial. The device stores your private keys offline and you hold the seed phrase, so you control the crypto rather than a company.
Which wallet type suits beginners?
Many beginners start with a custodial exchange account because it is simpler, then move long term holdings to a hardware wallet once they are comfortable with seed phrase security and test transfers.
