The universal wallet : unlocking the future of crypto wallets

published on 30 May 2023

In the fast-evolving world of cryptocurrencies and decentralized applications, the emergence of the Universal Wallet has sparked excitement and potential. This revolutionary type of wallet combines the functionality of managing both data (in the form of verifiable credentials) and cryptocurrencies, including coins and Non-Fungible Tokens (NFTs). Built on the foundation of Self-Sovereign Identity (SSI), the Universal Wallet offers a seamless integration of data signing and transaction capabilities on Distributed Ledger Technology (DLT). 

In this article, we delve into the significance of Universal Wallets, their potential to reshape the crypto landscape, and their pivotal role in the Web3 ecosystem.


The universal wallet: beyond traditional wallet functions

In the realm of digital wallets, the Universal Wallet stands out for its versatility and expanded capabilities. The Altme wallet is a good example. It transcends the conventional boundaries of wallet functions, incorporating the management of diverse data types, such as verifiable credentials, alongside cryptocurrencies and NFTs. With a Universal Wallet, users can securely store and interact with various assets within a single application. This unified approach streamlines user experience and simplifies the management of digital assets.

Real-world application: universal wallets as a multi-purpose tool

Drawing parallels with real-life scenarios, the Universal Wallet mirrors our everyday use of multiple cards and identifiers. Just as we carry loyalty cards or student IDs to access specific benefits or discounts, a Universal Wallet encompasses these functionalities within the digital realm. It harmonizes various aspects of personal identification, payment, and loyalty, making it a comprehensive solution for managing digital interactions.

Decentralization in web3: debunking the myth

While Web3 platforms often promote the ideals of decentralization, the reality may differ. Many platforms that champion decentralization ironically rely on centralized databases to store user information. This discrepancy challenges the true essence of decentralization and underscores the importance of Self-Sovereign Identity.

SSI empowers individuals to retain control over their personal data, ensuring that it remains with them and enabling selective sharing as desired.

Self-Sovereign Identity: transforming customer databases, similar to DeFi for banks

The emergence of SSI is a natural progression in the exploration of decentralization. Just as Decentralized Finance (DeFi) transformed banking by removing intermediaries, SSI revolutionizes the management of customer databases. Personal data, unlike blockchain-based assets, is non-transferable and intimate to individuals.

SSI recognizes this distinction and ensures that personal data is securely stored within the Universal Wallet, giving users ultimate control over its usage.

The wallet's prominent role: Ownership and control of personal data

In the Web3 ecosystem, crypto wallets play a central role in the ownership and control of personal data. By shifting data from centralized servers to wallets, individuals retain direct ownership and exercise complete control over their information. Wallets become the custodians of personal data, empowering users to decide when and how to share it. This newfound control represents a fundamental shift in the relationship between individuals and their digital identities.

The universal wallet for everyday use: addressing ethical concerns

In the context of NFT marketplaces, ethical concerns arise regarding the sale of high-value NFTs to underage individuals. Universal Wallets provide a solution by incorporating age verification processes and integrating built-in Know Your Customer (KYC) verifications. Once verified, this information is stored securely within the Universal Wallet (in the new verifiable credential format), allowing for seamless and responsible participation in NFT marketplaces or age-restricted platforms.

Web3 beyond cryptocurrencies: towards a balanced and fair Internet 🌐

While cryptocurrencies are a significant focus of Web3, the long-term vision extends far beyond digital currencies alone. Web3 aims to create a more equitable internet, fostering fair exchanges, reducing intermediation, and establishing a closer connection to real-world experiences. Universal Wallets, acting as powerful tools within this ecosystem, embody these values by enabling secure data management and facilitating seamless interactions.


The Universal Wallet represents a groundbreaking innovation in the world of crypto wallets, revolutionizing the way individuals manage their digital assets and personal data. With its ability to integrate both cryptocurrencies and various forms of data such as verifiable credentials, the Universal Wallet offers users a comprehensive and streamlined experience.

As the Web3 ecosystem continues to evolve, the Universal Wallet emerges as a pivotal component, enabling individuals to retain ownership and control over their personal data. With Self-Sovereign Identity at its core, users have the power to selectively share their data, ensuring privacy and security.

Furthermore, the Universal Wallet transcends traditional wallet functions, mirroring real-life scenarios where multiple cards (verifiable credentials) serve different purposes. Loyalty cards, student IDs, and more can all be consolidated into a Universal Wallet, providing users with convenience and versatility in their digital interactions.

We encourage our readers to try the unified and user-centric approach of the Altme wallet (available on iOS and Android) to manage their digital assets and personal data securely while protecting their privacy.
