The Future of Web3 Wallets: Innovation, Challenges, and Key Issues

Web3 wallet is undergoing a revolutionary transformation. This article will delve into the current innovations, challenges, and future development directions, providing a framework for builders and investors to evaluate long-term value.

Wallet 1.0 Status

Currently, digital wallets are mainly divided into custodial and non-custodial categories. Non-custodial wallets can be further subdivided into externally owned accounts (EOA) wallets, smart contract wallets, and multi-party computation (MPC) wallets.

EOA wallets are the most common type, such as Metamask and Phantom. Smart contract wallets like Argent and Safe offer more advanced features. MPC wallets like Fireblocks and ZenGo enhance security using threshold encryption technology.

Current Challenges

Despite progress, cryptocurrency wallets still face several key challenges:

• Ordinary users find it difficult to understand and use
• The login and setup process is complicated.
• The risk of losing mnemonic phrases is high
• Fragmentation of wallets across different chains

Innovation of Account Abstraction

The emergence of Ethereum account abstraction (AA) has brought significant advancements to Web3 wallets. The ERC-4337 standard introduces several key features:

• Social Recovery
• Atomic Multi-Operation
• Pay transaction fees using ERC20 tokens
• Paymaster feature

These features greatly enhance the usability and accessibility of the Wallet.

The Future of Wallet 2.0

Wallet 2.0 will address the current limitations and introduce new features to enhance security and functionality. Some emerging Wallet 2.0 projects include Castle, Soul Wallet, Candide, etc.

Evaluating the Five Key Issues of Wallet 2.0

1. Is this a great business model?

Factors such as revenue streams, customer acquisition costs, and profitability need to be considered.

2. Can it provide advantages that are 10 times greater than existing solutions?

Will new features like social recovery bring substantial improvements?

3. How to establish a sustainable competitive advantage?

It can be achieved through unique distribution channels or viral propagation.

4. Is it possible to add smart contract functionality through existing products?

Collaborating with exchanges or DeFi protocols can be an effective approach.

5. What key assumptions are needed for success?

If users value enhanced security, can provide a good user experience, etc.

Potential Risks and Limitations

• ERC-4337 does not completely solve the high gas fee issue.
• Introduce new security risks
• Cross-chain interoperability needs improvement
• There is uncertainty in legal and regulatory aspects.

Conclusion

Wallet 2.0 represents the future of digital asset management. It will provide users with safer and more user-friendly solutions. Builders should focus on establishing sustainable advantages, optimizing user experience, ensuring security, and closely monitoring industry trends. In the future, we can expect to see more advanced designs, better key management solutions, and new use cases for Wallet 2.0.
