Custodial vs Non-custodial wallet: Where to best keep your crypto

Updated: Jun 30



Just like fiat money, you need to store your crypto assets in a safe but accessible wallet. A crypto investor has two options: a custodial and non-custodial wallet. Your choice of wallet determines the level of user responsibility and security measures you must put up.


But before we explore your options, let’s explore the concept of private and public keys, which are essential in understanding the difference between custodial and non-custodial wallets.


Public vs. Private Keys

All crypto wallets have a pair of public and private keys. Both consist of a complex code of alphanumeric characters used to keep the account and assets safe.

  • The public key is the code that enables the user to facilitate crypto transactions and allows them to receive crypto in their accounts. It’s a public-facing data point that serves as the deposit address.

  • The private key is the code that authorizes the user to withdraw, transfer, spend, or carry out other crypto transactions. Unlike the public key, the private key is known only to the user and serves as their digital ID.

Together, this pair enables the transfer of coins from one place to the other. If you’re sending coins to a wallet, you input the public key then authorize the transfer via the private key.


The private key spells the difference between custodial and non-custodial wallets.


Custodial Wallets

When you use a custodial wallet, you don’t have the private key. Instead, you trust the wallet as the custodian of your private key and count on it to make your assets available to you whenever you need them.


Custodial wallets have a lot of advantages:

  • There’s less user responsibility because you don’t have to worry about keeping your private key safe

  • It’s easier to use because you only need a username and password to log in

However, there’s an added layer of security risk, since these platforms can be hacked, and malicious actors could drain your account.

Non-Custodial Wallets

When you use non-custodial wallets, you possess a private key. You don’t have to trust a third party to keep your private key safe, and in essence, you are fully responsible for its safekeeping.

A lot of crypto investors use non-custodial wallets because it:

  • Eliminates third parties between you and your crypto assets; and

  • Gives you the full freedom of a decentralized financial platform

But as Spiderman puts it, with great power comes great responsibility. Non-custodial wallet users must keep their private keys secure because if they’re lost, the coins might also be lost forever. In addition, they must have a solid grasp of backing up and restoring wallets.

You have a myriad of options, but at the end of the day, it’s up to you to determine which you prefer. In fact, you don’t have to choose — many crypto owners use a combination of custodial and non-custodial wallets. What’s important is you study each option diligently and be prepared for the risk that each entails.
