Vitalik Buterin personally tests multi-signature wallet experience: Why open source and verifiability are reshaping the Ethereum user experience

On January 28, news, Ethereum co-founder Vitalik Buterin shared a real on-chain operation experience on the decentralized social platform Farcaster, sparking discussions among developers and users about wallet design and blockchain explorer capabilities.

Vitalik stated that on that morning, he needed to check the signature address in his multi-signature wallet, but at the time he was using a mobile device and had not installed his usual wallet app. In this situation, he was not limited by a specific frontend but directly queried the address through a blockchain explorer and used the “Read Contract” feature to obtain the necessary information, successfully completing the operation.

He pointed out that this experience relies on the wallet and related applications being open source, and their contract logic having undergone security audits. It is precisely because the contract interfaces are public and the logic transparent that users can switch freely between different tools without being “locked” by the availability of a particular website or app. In real-world scenarios, webpage load failures and service disruptions are common; providing alternative pathways for users is often more reliable than relying on a single entry point.

In further reflection, Vitalik also mentioned the privacy challenges. He believes that the current method of directly reading contract states via blockchain explorers may be limited by privacy needs in the long run. A theoretical improvement could be to introduce a “view key” mechanism, allowing users to authorize queries without exposing all information, but this also introduces new security risks, such as users pasting sensitive information into web pages or URLs.

Therefore, he emphasized that the truly ideal direction is to enable wallets to have stronger native capabilities, allowing more operations to be completed directly within the wallet rather than relying on external tools. This view is also seen as a microcosm of the Ethereum ecosystem’s search for a balance between usability, decentralization, and privacy.
