A non-custodial wallet is a crypto wallet where only you hold the private key. In other words, no company can freeze it, block a transfer or restore it for you. That is why it is also called a self-custody wallet: you are your own bank.
A custodial wallet, by contrast, works the other way around. A provider keeps the keys, and you log in to an account. So below we compare the two models, show examples and explain who each one suits. If you want the short version of where keys live, see our guide on cold wallet vs hot wallet.

What a non-custodial wallet is
Every crypto wallet holds a private key, and whoever controls that key controls the coins. In a non-custodial wallet, the key is created on your device and stays there. As a result, nobody else ever sees it.
Instead of a password reset, you therefore get a backup. Usually it is a seed phrase of 12 or 24 words, sometimes a set of backup cards. If you keep the backup safe, you can restore the wallet on any compatible device. However, if you lose both the device and the backup, the coins are gone for good.
Crypto users sum this up in one line: not your keys, not your coins.
For example, when a large exchange collapsed in 2022, its customers could not withdraw their coins for a long time. Meanwhile, people who kept coins in their own wallets were not affected at all. That is the main reason self-custody became popular.
What a custodial wallet is
In a custodial wallet, a company stores the keys for you. You sign in with an email, a password and two-factor authentication. As a result, a forgotten password is not a disaster, because support can restore access after a check.
As a rule, exchanges and payment apps work this way. The SharPay crypto wallet is custodial too. In fact, that is what lets it convert coins to euro, pay out to cards and connect to a payment card in one app.
Custodial vs non-custodial wallet compared
| Non-custodial wallet | Custodial wallet | |
|---|---|---|
| Who holds the key | You | The provider |
| Lost access | Restore only from your backup | Support restores access |
| Identity check | Usually none | Required |
| Euro and cards | Not built in | Built in |
| Main risk | Losing the backup, scams | Trusting the provider |
| Best for | Long-term savings | Payments and cashing out |
Non-custodial wallet examples
Non-custodial wallets come in three main forms:
- Hardware wallets. A device keeps the key offline, for example a card, a USB gadget or a ring. Our overview of the best cold wallets compares Tangem, Ledger and Trezor.
- Mobile apps. The key sits in the phone’s secure storage. Such apps are free and handy, yet the phone is online.
- Browser extensions. They connect to websites and online services. On the other hand, they face the most phishing.
Overall, a hardware wallet is the safest of the three, since the key never touches the internet. Our guide to the cold wallet explains how it works.
Pros and cons of self-custody
The main advantage is control. Nobody can freeze your coins, and they stay yours even if a service closes. Moreover, you can usually start without an identity check.
However, the downside is responsibility. There is no support line that restores a lost seed phrase. In addition, mistakes are final: coins sent to a wrong address will not come back. Besides, scammers target self-custody users with fake apps and fake support chats.
Pros and cons of a custodial wallet
On the other hand, a custodial wallet is easier to live with. You can reset a password, and support helps if something goes wrong. Above all, it connects crypto to everyday money: exchange to euro, cards and payouts.
Still, the trade-off is trust. Your coins depend on the provider’s security and licence. So before you choose one, check that the company is regulated and transparent about fees. In the EU, firms that hold crypto for clients need authorisation under the MiCA rules.
Which one to choose
For most people the honest answer is both. Keep long-term savings in a non-custodial wallet, ideally a hardware one. Then keep the money you plan to spend in a custodial wallet linked to a card.
In practice, the split is simple. First, decide how much you spend in a month. Then keep about that amount on the spending side and move the rest to self-custody. Finally, top up the spending wallet when it runs low.
With SharPay, that spending side is covered. You send coins from your own wallet to SharPay, exchange them and pay with a virtual card you can top up with crypto wherever Visa and Mastercard are accepted.
How to set up a non-custodial wallet safely
- Download the app or buy the device only from the official website.
- Create a new wallet yourself; never accept a pre-set phrase.
- Write down the backup on paper or metal and keep it offline.
- Send a small test amount and practise a restore.
- Only then move the main sum.

Frequently asked questions
Is a non-custodial wallet anonymous? Not fully. Every transfer is public on the blockchain, and services that pay out to cards check your identity.
Can I move coins from a custodial to a non-custodial wallet? Yes. Withdraw them to your own wallet address, using the same network on both sides.
Is the SharPay wallet custodial? Yes. SharPay keeps the keys, verifies users and connects the wallet to cards and euro payouts.
