What is a non-custodial wallet?

A non-custodial wallet, also known as a self-custody wallet, is a crypto wallet that enables users to take full ownership and responsibility for their assets.

A non-custodial wallet does not hold custody of your crypto. Many people prefer non-custodial wallets as they eliminate the need for a third party, providing higher security.

These wallets can come in various forms: browser-based, software on mobile devices or desktops, and hardware devices like USB sticks.

How do non-custodial wallets work?

During a transaction, the signing of the transaction by the private key is done offline within the hardware wallet itself before being sent online to the blockchain for confirmation. This process ensures that even if your computer or phone is infected with malware, it cannot access your funds.

Overview of non-custodial wallets

Self-custody wallets have several benefits that make them attractive to cryptocurrency newcomers, but they also have certain drawbacks. However, the pros and cons are relative to each user and their tastes and level of technical knowledge.

  1. Users’ control over funds: Non-custodial wallets provide individual access to funds, eliminating the need for third-party management.
  2. Safety in funding: Since all wallet details and funds are under the user’s control, the risk of data breaches is lower, making non-custodial and mobile storage solutions popular among 66.5% of crypto holders.

Cons of a non-custodial crypto wallet

Non-custodial wallets come with a set of disadvantages:

  1. Self-responsibility: Users need to take full responsibility for the security of their private keys and wallets. Unlike with custodial wallets, if you lose access, forget passwords, or mishandle the recovery seed phrase, you may permanently lose all of your digital assets.
  2. No third-party assistance: Non-custodial wallets lack password resets or customer support for recovery, making it more challenging to regain access compared to custodial wallets.
  3. Increased complexity: Managing keys and ensuring fund safety can be more complex, especially for newcomers.
  4. Higher risk of loss: Inadequate safeguarding of keys or recovery phrases can lead to fund loss, as there is no centralized authority to assist with recovery.
  5. No insurance coverage: Unlike some custodial wallets, non-custodial wallets typically do not offer insurance coverage, leaving users fully responsible for any losses or security breaches.

Additional drawbacks include trade delays, increased responsibility for security, potentially difficult user interfaces, and the risk of permanently losing access to wallets and funds if private key or seed phrases are lost without any backup and recovery options.

Types of non-custodial wallets

Software wallets

Software wallets function like any other software application, and they are considered ‘hot wallets’ due to their internet connectivity, ensuring better accessibility. These wallets remain connected to the internet in one way or another, making them easily accessible for users.

They come in various forms, each offering different features and accessibility options. One type is the web wallet, which operates through internet browsers, providing practical management of cryptocurrencies online, and facilitating transactions with web-based marketplaces.

Another variant is the desktop wallet, where you download the software to your computer, offering enhanced control and security as it is locally installed on your device.

For those who prefer mobile access, mobile wallets are available for download on smartphones. They allow flexible and convenient on-the-go access to funds.

Both desktop and mobile wallets incorporate safety features. However, specifics may vary depending on the wallet provider.

Some software wallet providers also offer browser extensions for Chrome and Firefox. It provides seamless and accessible cryptocurrency management directly from desktop or mobile devices.

A hardware wallet is an external device that stores your private key and cryptocurrencies. This non-custodial wallet operates as a form of cold storage, similar to encrypted external hard drives.

However, by withdrawing the funds to this non-custodial wallet, you gain greater control and security because the digital assets are removed from the online exchange and can only be accessed using the physical wallet and a private key.

The main advantage of a hardware wallet is its stability and enhanced security. Since the wallet remains offline most of the time, the risk of viruses and hackers accessing your private key is minimal.

While these wallets offer excellent security, they may be less convenient than other wallet options as they require physical access and PIN entry. However, if you have significant cryptocurrency investments and prioritize security, a hardware wallet is an ideal choice.

Also, unlike software crypto wallets that store keys on the internet, these wallets keep the private keys on the device. It makes them less susceptible to hacking and malware attacks.

Moreover, usually, this kind of non-custodial wallet is portable. Therefore, you can easily carry it around as a secure private key to access crypto assets from anywhere.
