Ethereum co-founder Vitalik Buterin outlined the blueprint of an ideal crypto wallet in his latest blog, focusing on security and privacy. 🌐He suggested using chain-specific address formats, such as address@optimism.eth, in cross-L2 transactions to simplify cross-chain operations.

In terms of account security, Vitalik recommends social recovery and multi-signature mechanisms, especially 2-of-3 protection schemes, combined with zk-email, local keys, and service provider backup keys to provide security for new users.

In terms of privacy protection, he advocates integrating privacy pools and stealth address functions into mainstream wallets to protect user privacy by default. 🔒In addition, Vitalik also suggested that wallets evolve into personal data storage tools, using M-of-N key sharing mechanisms to ensure data security.

He also discussed enhancing secure chain access through light clients and PIR technology, and called on developers to use on-chain content versioning to improve DApp security. 💡This vision points the way for the future development of crypto wallets.
