Vitalik published an article outlining the development blueprint for the ideal crypto wallet, focusing on cross-L2 transactions and privacy protection

ChainCatcher message, Ethereum co-founder Vitalik Buterin published a latest blog post detailing his vision for the ideal crypto wallet. The article focuses on security and privacy, proposing key features such as cross-L2 transaction experience, account security, fraud prevention, and data wallets.Regarding cross-L2 transactions, Vitalik suggests adopting chain-specific address formats (e.g., address@optimism.eth) and recommends that wallets automatically handle cross-chain exchanges and transfer processes. For account security, he advocates for social recovery and multi-signature mechanisms, proposing a 2-of-3 protection scheme for new users, which includes zk-email, local keys, and service provider backup keys.On privacy protection, the article emphasizes the need to integrate features like privacy pools and stealth addresses directly into mainstream wallets to achieve default privacy. In terms of data storage, Vitalik suggests that wallets evolve into personal data storage tools, using an M-of-N key sharing mechanism to protect user data. The article also explores secure chain access mechanisms, recommending the enhancement of wallet security through light clients and private information retrieval (PIR) technology, and calls on developers to adopt on-chain content version control to improve DApp security.
