Are professional crypto custody services worth it?

Asset custodians storing investments like equities and gold are well-established in traditional finance, so it’s no surprise that a similar vertical has emerged in the crypto industry.

However, rather than protecting assets, which exist on a public blockchain, crypto custody guards private keys, the unique string of alphanumeric characters that provide access to a wallet (as opposed to a public key which is the openly shared wallet address).

Holders of crypto assets can choose between non-custodial wallets and custody services. This blog post explores the differences between these options and their advantages and disadvantages to help you determine which one meets your needs.

What are non-custodial wallets?

Non-custodial or self-custody wallets put you as the user in complete control of your funds as you take full responsibility for storing your private keys.

By cutting out the need for a third party, non-custodial wallets eliminate counterparty risk which arises if an exchange is hacked or goes bankrupt. But you could still lose your holdings if you misplace your password or your wallet isn’t backed up properly. In fact, crypto data firm Chainalysis estimates that around 20% of all bitcoin is stranded in wallets that users no longer have access to. While a ‘recovery’ or ‘seed’ phrase — a cluster of random words generated when setting up a wallet — provides a backup that can be used to regain access, like a private key, this must be securely stored.

Types of non-custodial wallets

As the name suggests, browser wallets are accessed directly from a web browser. Users download and install an extension, although some browsers come with built-in wallets. One of their most appealing features is they simplify the process of interacting with decentralized apps and exchanges as they connect at the click of a button. Browser wallets are known as ‘hot’ storage as the data they hold is accessible online.

Software wallets are downloaded and installed on a desktop or mobile device. The mobile version is particularly popular among those who use crypto as a medium of exchange as it makes sending and receiving tokens easy, for example by scanning a QR code. Software wallets are another form of hot storage.

Hardware wallets are the most secure way to self-custody crypto, but they’re also the most inconvenient. They typically take the form of USB devices and to transact, these devices need to plug into a laptop or desktop or connect via Bluetooth. Hardware wallets are referred to as ‘cold’ storage as they store user data offline.

The role of a crypto asset custodian

When using a crypto custody service, clients entrust their private keys and the security of their holdings to a third party.

Custody services are suitable for crypto holders who prioritize peace of mind. If you forget your password, you can create a new one relatively easily, rather than lose access to your funds. Custody services are also popular among clients with large crypto holdings who value the extra layers of security and may need multi-signature wallets if several decision-makers manage the funds.

Most custody service providers employ a combination of hot and cold storage, although Finoa has developed a proprietary ‘warm’ storage solution. By combining a custom-built core banking system, a digital banking interface, and proprietary blockchain private key technology, warm storage unites the flexibility of hot storage with the security of cold storage.

Who provides crypto custody services?

Many crypto exchanges provide wallets where users can store the tokens they purchase. Some exchanges have built their own custody solutions, while others outsource it to third parties.

As the industry has evolved and demand has increased, a new breed of digital asset custodians has emerged offering custody services to crypto holders. Finoa is a digital asset custodian.

Mainstream banks also offer crypto custodial services. For instance, in July 2020, the Office of the Comptroller of the Currency, the US financial regulator tasked with ensuring a safe and sound banking system, started allowing nationally chartered banks to become crypto custodians.

When choosing a crypto custody provider, it’s important to check that the company is regulated by its local financial authority and licensed to act as a custodian (Finoa is supervised by Germany’s BaFin — Bundesanstalt für Finanzdienstleistungsaufsicht). Regulated entities must subject clients to the same compliance requirements as mainstream financial institutions, such as Know-Your-Customer (KYC) and anti-money laundering checks, to ensure their funds come from a legitimate source.

Fees are another consideration. Crypto custody fees vary, but they generally fall into three categories:

  • A set-up fee to open a crypto custodial account
  • An annual fee based on the value of the assets in custody (typically under 1%)
  • A withdrawal fee levied when removing funds from an account, either a flat rate or a percentage of the amount withdrawn

One final note on crypto custody services — they aren’t available to everyone. Some providers only accept institutional clients, while others enforce a minimum position size.
