Web3 wallet

Web3 wallets are an integral part of the blockchain ecosystem that allows users to interact with various decentralised applications (DApps), store cryptocurrencies and manage digital assets. Unlike traditional financial instruments, Web3 wallets provide an increased level of security, transparency and autonomy for their users.

Custodial and non-custodial Web3 wallets

Web3 distinguishes between two main types of wallets: custodial and non-custodial. These terms refer to the level of control a user has over their private keys, and therefore their assets. Understanding the differences between these types of wallets is important for choosing the right option for storing cryptocurrencies and other digital assets.

Custodial wallets

Custodial wallets are wallets whose private keys are managed by a third party, such as an exchange platform or storage service. Users do not control their keys directly, which means that they also do not have full control over their assets.


  • Ease of Use: Custodial wallets often offer a simpler and easier to understand interface, making them accessible to novice users.

  • Customer Support: Users can contact customer support if there are any problems with account access or transactions.

  • Restoring access: In case of loss of access to the account, for example, when the password is lost, there is a possibility to restore it through the service.


  • Security Risk: Storing keys with a third party increases security risks such as hacker attacks and insider threats.

  • Dependence on third-party services: The presence of an intermediary increases the risks associated with bankruptcy or closure of the service.

Non-custodial wallets

Non-custodial wallets give users full control over their private keys and thus their assets. This means that the keys are stored directly on the user's device or in the user's personal software.


  • Full control over assets: Users manage their funds and can initiate transactions themselves without intermediaries.

  • Increased security: No centralised key storage reduces the risk of hacker attacks.

  • Independence: Users are not subject to the policies or terms and conditions of third-party services.


  • Security responsibility: All responsibility for keeping the keys safe rests with the user, which can be difficult for beginners.

  • Recovery Difficulty: If keys are lost, it is virtually impossible to regain access to assets.

Types of Web3 wallets

Web3 wallets are various solutions for storing and managing cryptocurrencies and other digital assets. They are categorised based on their functionality, level of security and ease of use. Let's take a closer look at each type:

Hardware wallets

Hardware wallets are physical devices that provide storage of private keys in a secure, isolated environment. These wallets are highly secure, as the keys never leave the device and are not at risk of online attacks. 

Software wallets

Software wallets are installed on computers or smartphones and provide an interface for asset management. They may be susceptible to cyberattacks, but offer ease of use and quick access to assets.

Paper wallets

Paper wallets are the simplest way to store cryptocurrencies. Private and public keys are printed on paper and stored in a safe place. This method is considered one of the safest, but is inconvenient for frequent transactions.

Web wallets

Web wallets are accessible through a browser, making them convenient for quick transactions. However, they can also be vulnerable to online attacks because private keys are stored on a server or managed by a third party.

Mobile wallets

Mobile wallets are smartphone applications that allow you to manage your assets on the go. They are convenient, support various features such as QR code scanning, and offer an acceptable level of security.

Smart contract wallets

Smart contract wallets use smart contract code to manage transactions, which may include multi-factor authorisation mechanisms or conditions that must be met for a transaction to take place. They offer advanced security and customisation features.

Desktop wallets

Desktop wallets are programmes that are downloaded and installed on personal computers. They offer a high level of security and convenience, especially if they are not connected to the internet (cold storage).

Main features and functionality of Web3 wallets


One of the key features of Web3 wallets is that they give the user full control over their private keys and, consequently, over their assets. Unlike traditional banking systems, where asset management is often in the hands of third parties, Web3 wallets function without intermediaries. This means that only the wallet owner has access to their funds and the authority to use them, ensuring a high level of security and privacy.

Integration with DApps

Integration with decentralised applications (DApps) is another important aspect of Web3 wallets. Users can interact directly with a variety of blockchain-based applications through their wallet. This includes games, financial platforms, decentralised exchanges and more. Integration with DApps extends the functionality of wallets, allowing users to not only store assets but also actively participate in the blockchain economy.

Support for multiple assets

Most Web3 wallets offer support for a wide range of cryptocurrencies and tokens. These include not only major currencies such as Bitcoin and Ethereum, but also many other altcoins, as well as tokens of ERC-20, ERC-721 (NFT) and other standards. This multi-asset support makes Web3 wallets versatile tools for managing and trading different types of digital assets. Users can easily switch between different assets and use them according to their needs in different DApps.
