Non-custodial and custodial wallets for storing cryptocurrencies


The idea behind cryptocurrencies is to decentralize, giving each user completely independent control over their funds and managing private keys. There is a phrase “not your keys – not your bitcoin”. Nevertheless, today many services (crypto wallets and crypto exchanges) provide custodian services, that is, they themselves are engaged in storing user funds. In some situations, this is even convenient.

The editorial staff of proposes to consider the pros and cons of custodial and non-custodial wallets.

What are non-custodial and custodial wallets ?

A non-custodial wallet is a type of decentralized wallet in which the client owns their private keys. At the moment of creating a wallet, the user is given a file with private keys, as well as a mnemonic phrase, with which it will subsequently be possible to restore access to the management of funds.

In contrast, a custodial wallet stores the client’s private keys on its own side and is responsible for backing them up and securing user assets. The answer to the question of why many users agree to such terms is convenience. Wallets of this type are much easier to learn, access to them is carried out simply by login and password, at the touch of a button.

Expert opinions

Despite occasional news of centralized cryptocurrency exchanges and custodial wallets being hacked, many traders and investors continue to hold significant amounts of money on such platforms. Well-known industry experts think about this:

  • Stephen Quinn, manager of cryptocurrency exchanges Eosfinex and Bitfinex, believes that the future belongs to decentralized platforms. He notes that the currently existing non-custodial services are not devoid of many disadvantages (for example, low scalability, limited by the technical capabilities of the blockchain), but their most important advantage lies in the absence of storage.
  • Curtis Spencer, managing partner at venture capital firm Electric Capital, notes that non-custodial services are not as transparent and censorship-free as commonly believed, but it is still cleaner and more community-driven than custodian platforms.
  • Alan Curtis, CEO of Radar Relay wallet, says that the introduction of non-custodial functions is a big leap into the world of decentralized finance. Since 2011, more than 50 hacks have been identified on centralized exchanges, resulting in the loss of private user information and billions of dollars.
  • Eric Voorhees, CEO of ShapeShift, talks about the need to take people away from custody services. Non-custodial wallets and exchanges provide a fundamentally secure way for individuals to store and exchange digital assets.


Cryptocurrency market trends show that non-custodial wallets will gain an edge over custodial wallets in the near future. This is due to numerous cases of security breaches of centralized services. Users are increasingly jealous of their funds and privacy. Non-custodial services offer ample opportunities and have good prospects, so it is highly desirable to master working with them.
