According to BlockBeats, on December 3, Ethereum co-founder Vitalik Buterin published a new blog post detailing his vision for an ideal crypto wallet. "A key layer of the Ethereum infrastructure stack is the wallet, but core L1 researchers and developers often underestimate this. The wallet is a window between the user and the Ethereum world, and users can only benefit from the decentralization, anti-censorship, security, privacy or other properties provided by Ethereum and its applications if the wallet itself also has these properties."
In cross-L2 transactions, Vitalik proposes using chain-specific address formats (e.g., address@optimism.eth) and suggests that wallets automatically handle cross-chain exchanges and transfer processes. Regarding account security, he recommends implementing social recovery and multi-signature mechanisms, with a 2-of-3 protection scheme for new users, including zk-email, local keys, and service provider backup keys. On privacy protection, the article emphasizes the need to directly integrate features like privacy pools and stealth addresses into mainstream wallets to achieve default privacy.
In terms of data storage, Vitalik suggests that wallets evolve into personal data storage tools, adopting an M-of-N key-sharing mechanism to protect user data. Looking ahead, Vitalik predicts that new technologies like AI and brain-computer interfaces will fundamentally change how wallets are interacted with.
Ideally, in terms of Dapp security, the ecosystem would shift to on-chain content version control: users would access the dapp via their ENS name, which would contain the IPFS hash of the interface. On-chain transactions from multi-signature or DAO would be required to update the interface. The wallet would show users whether they are interacting with a more secure on-chain interface or a less secure web2 interface. The wallet could also indicate whether they are interacting with a secure chain (e.g., Phase 1+, multiple security audits).
