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

Vitalik Buterin, co-founder of Ethereum, has released a new blog post detailing his vision for the ideal encrypted wallet. The article focuses on security and privacy, proposing key features such as cross-L2 transaction experience, account security, anti-fraud, and data wallets. Regarding cross-L2 transactions, Vitalik proposes using chain-specific address formats (such as [email protected] ) and suggests that wallets automatically handle cross-chain exchange and transfer processes. In terms of account security, he recommends using social recovery and multi-signature mechanisms, adopting a 2-of-3 protection scheme for new users, including zk-email, local keys, and service provider backup keys.

Regarding privacy protection, the article emphasizes the need to directly integrate privacy pool and stealth address functions into mainstream wallets to achieve default privacy. In terms of data storage, Vitalik suggests that wallets evolve into personal data storage tools, using M-of-N key sharing mechanisms to protect user data. Looking to the future, Vitalik predicts that new technologies such as AI and brain-machine interfaces will completely change wallet interaction methods.
