PANews reported on December 3 that Ethereum co-founder Vitalik Buterin elaborated on his vision for an ideal crypto wallet in his latest blog post. The article states that 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 terms of cross-L2 transactions, Vitalik proposed the use of chain-specific address formats (such as address@optimism.eth) and suggested that wallets automatically handle cross-chain exchange and transfer processes. In terms of account security, he recommended the use of social recovery and multi-signature mechanisms, and the use of 2-of-3 protection schemes for new users, including zk-email, local keys, and service provider backup keys. Regarding privacy protection, the article emphasizes the need to integrate features such as privacy pools and stealth addresses directly into mainstream wallets to achieve default privacy. In terms of data storage, Vitalik suggested 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-computer interfaces will completely change the way wallets interact. In terms of Dapp security, ideally, the ecosystem will be moved to on-chain content versioning: users will access dapps through their ENS names, which will contain the IPFS hash of the interface. On-chain transactions from multi-signatures or DAOs are required to update the interface. Wallets will show users whether they are interacting with a more secure on-chain interface or a less secure web2 interface. Wallets can also show users whether they are interacting with a secure chain (e.g. Phase 1+, multiple security audits).
