A self-custodial wallet, also known as a non-custodial wallet, is a type of cryptocurrency wallet that allows users to manage their private keys and have direct control over funds stored on a blockchain network.

TL;DR

  • Self-custodial wallets allow users complete control over their private keys and crypto assets.
  • Setting up a self-custodial wallet does not require the user to share any personal information with a third party.
  • DeFi and GameFi platforms often require self-custodial wallets because they allow users to interact directly with smart contracts and decentralized applications.
  • In the early days of cryptocurrency, all wallets were self-custodial. Today, this type of wallet may not be a good choice for new users who don’t understand asymmetric cryptography’s role in blockchain transactions.

How Does a Self-Custodial Wallet Work?


Self-custodial wallets allow users to manage their own crypto assets without relying on a third-party intermediary. However, the autonomy that self-custodial wallets provide comes with a trade-off in terms of increased responsibility.

Unlike custodial wallets provided by crypto exchanges, self-custodial wallets allow users to interact directly with a blockchain network, manage their own private keys, and avoid third-party restrictions on account access or withdrawals.

While this reduces the risk that funds could be lost due to exchange hacks, mismanagement, or changes in crypto regulations, it also increases the risk of permanently losing funds.

If the user doesn’t understand how to manage private keys, or if they lose the seed phrase the wallet initially generated to assist with recovery, it may not be possible to access the wallet and regain control of the digital assets.

Ironically, the lack of third-party support means that users are solely responsible for managing private keys and seed phrases.

Key Features of a Self-Custodial Wallet


Self-custodial wallets have four important features that allow users to:

  • Manage their crypto wallet without needing to share any information with a third party
  • Directly access blockchain networks when conducting transactions
  • Store private keys locally and retain total control over them
  • Use a seed phrase to restore access to funds on a new device

Self-Custodial Wallet Types


There are three basic types of self-custodial wallets:

self custodial wallet types

  • Software wallets: Digital wallets that can be accessed through a dedicated app, desktop application, or browser extension.
  • Hardware wallets: Physical devices that are designed to store private keys offline securely.
  • Paper wallets: These are simply keys printed out on paper. This type of self-custodial wallet is less common now that hardware and software wallets have become more user-friendly.

Examples of Self-Custodial Wallets


Privacy and security email firm Proton recently introduced the Proton Wallet, a self-custody Bitcoin-only wallet that allows users to hold digital assets. Other popular self-custodial wallets include MetaMask, Phantom, MyEtherwallet, and Exodus.

Self-Custodial Wallet vs. Custodial Wallet: Key Differences


So, what is the difference between a custodial and self-custodial wallet?

Self-custodial wallets offer complete control and privacy but require users to take responsibility for key management and security. In contrast, custodial wallets are more user-friendly but depend on third parties for key management and security.

Feature Self-custodial wallet Custodial wallet
Private keys The user manages their own private keys Private keys are held and managed by a third party
Access to funds The user has full control over access to funds A third-party custodian controls access to funds
Recovery responsibility The user is responsible for recovering lost keys Recovery options are typically available through the custodian
Security risks The user is responsible for managing loss risks The custodian bears some responsibility for managing loss risks
Restrictions The user has unrestricted access to funds Access to funds may be limited by custodian policies or government regulations
Anonymity and privacy Higher privacy; transactions are not monitored Lower privacy; transactions may be monitored

Five Reasons to Use a Self-Custodial Wallet


If you believe in the concept ‘not your keys, not your coins,’ then self-custodial wallets may help you sleep better at night for these five reasons:

reasons to use a self-custodial wallet

  1. Self-custodial wallets give users full ownership of their private keys, which means they have sole access to and control over their cryptocurrency.
  2. By storing private keys locally or on a hardware device, self-custodial wallets minimize exposure to centralized platforms that are frequent targets for cyberattacks.
  3. Non-custodial wallets can interact directly with DeFi platforms, GameFi platforms, smart contracts, and decentralized applications (dApps).
  4. Self-custodial wallets bypass centralized entities that might track transactions or impose restrictions.
  5. This allows users to participate in staking, liquidity pools, and other blockchain-based innovations that custodial wallets might not support.

Privacy & Self-Custodial Wallets


Self-custodial wallets are perhaps best suited for users who want complete control over their privacy and digital assets. Unlike the custodial wallets that centralized exchanges offer, self-custodial wallets typically do not require users to provide Know Your Customer (KYC) information.

What Are the Risks of Self-Custodial Wallets & Third-Party Service Providers?


Self-custodial wallets support the concept of decentralization. However, if the user wants to prevent their blockchain transactions from being traced back to the source, they may need to use third-party services after all.

That’s because transactions on most blockchains are public and traceable. To obscure transaction origins and prevent tracing, users may need to use third-party services that enable privacy-enhancing techniques like privacy coins or crypto coin mixing.

Self-Custodial Wallet Pros & Cons


Self-custodial wallets are not for everyone. While they offer great control and security, they also come with significant responsibility and potential risks.

Pros

  • Self-custodial wallets enable direct interaction with blockchain networks.
  • Users have complete control over their own private keys and crypto funds.
  • Self-custodial wallet setups do not require the user to share personal information.
  • Withdrawal limits are only determined by the user’s assets.

Cons

  • Losing the private key or seed phrase can result in the permanent loss of funds.
  • Key management can be intimidating for inexperienced traders and investors.

The Future of Self-Custodial Wallets


As more people become aware of the benefits of self-custody and this type of wallet becomes easier to use, non-custodial wallets will likely become more popular. DeFi, GameFi, and Web3 applications are expected to help drive adoption.

However, it’s important to note that governments are increasingly looking to regulate self-custodial wallets, which could impact their use and accessibility.

Conclusion


In the early days of cryptocurrency, every wallet required users to manage their own private keys because custodial wallets and exchanges didn’t exist yet.

As cryptocurrencies gained popularity, horror stories about lost keys and seed phrases encouraged the adoption of custodial wallets offered by crypto exchanges. These wallets provided convenience and customer support, making them appealing options for new investors and traders.

This shift made it necessary to explicitly define self-custodial wallets and educate users about the differences between self-custodial and custodial options.
