Vitalik points out Ethereum wallet experience shortcomings: ETF amplifies risks, "Unattended Testing" becomes a life-and-death line

On January 29, news revealed that Ethereum co-founder Vitalik Buterin exposed a critical weakness in crypto wallets during a seemingly ordinary multi-signature operation in a “watchless test.” He stated that when needing to query a multi-signature contract address, due to the Safe app not being installed on the phone, he had to use the “Read Contract” feature of a block explorer to complete the operation. This temporary workaround instead exposed the wallet’s vulnerability when the front end fails.

Buterin pointed out that if a wallet or application can still perform core operations using open-source tools after the front end disappears, it truly passes the “abandonment test.” This means users should not be locked into a single interface or application; otherwise, service interruptions could pose significant risks to asset management.

However, he also warned that this approach has privacy risks. Reading sensitive information through web pages or link parameters could lead to leaks. Ideally, more functions should be securely completed directly within the wallet rather than relying on external workarounds.

This discussion arises in the context of the US spot Ethereum ETF launch, which has accelerated the flow of structured funds into the digital asset market. As more institutions access Ethereum through traditional financial channels, the cost of product design flaws is significantly magnified. Any user experience issues could evolve into systemic risks in an environment of large-scale capital.

The developer community has proposed alternative solutions. For example, open-source tools like swissknifexyz and Microchain Labs’ “microchain zk signers” aim to reduce the complexity and exposure caused by explicit multi-signatures through zero-knowledge proofs.

In the current environment of rapid capital flow and increasingly financialized product forms, Buterin’s reminder is particularly relevant: if a system cannot continue to protect user rights in “无人操作” or “front-end disappearance” scenarios, the problem will ultimately manifest through market prices and trust erosion. For the Ethereum ecosystem, wallet experience is no longer an optional feature but a fundamental layer for security and scalable development.
