A wallet can make an action shorter without making its consequences easier to understand. Dev.Cooking’s view is that smart-wallet design should treat permission clarity as a core product feature. Convenience is valuable when the user can still identify what changed and how to regain control.
EIP-7702 defines a mechanism for externally owned accounts to delegate code execution. ERC-4337 describes an account-abstraction architecture around UserOperations and an EntryPoint contract. These are different specifications; neither is a blanket statement that every wallet using it offers the same recovery, sponsorship or safety features.
Explain the scope before the benefit
Consider a fictional application that asks a wallet to authorize a repeated action. Its interface should state the asset involved, the permitted operation, any spending boundary and the duration of the permission. It should also show which component enforces those boundaries.
Our proposed usability test is simple: ask a user to describe what the application can do after approval. If the user can only describe the immediate action, the interface has not communicated the continuing permission.
Separate a transaction from a delegation
In our suggested product model, an interface shows a one-time action and a change to ongoing authority in distinct ways. Even if a workflow combines them, the user should be able to inspect both. A familiar-looking confirmation should not make an unfamiliar permission disappear.
For example, a hypothetical assistant could prepare a payment and also ask for permission to prepare later ones. Those are two product decisions. Presenting them as one generic “continue” step makes the user’s choice harder to understand.
Treat recovery as a workflow to demonstrate
A recovery feature needs more than a label. Our evaluation asks which party can initiate it, what evidence is required, whether a delay applies and what the recovered user must do afterward. These questions must be answered by the wallet’s implementation and current documentation.
A team should demonstrate the workflow in an appropriate test environment before presenting it as a reason to trust the product. A protocol specification does not replace evidence about the actual recovery mechanism a wallet chose to build.
Make revocation discoverable
Our preferred permission dashboard shows active authorizations, their source and a clear route to change them. It also distinguishes a request that was never authorized from one that was authorized and later removed.
Imagine a user returning months after an application session. The dashboard should make sense without requiring the user to remember which marketing page originally described the feature. Persisted permissions deserve persisted explanations.
Do not hide the policy in an agent prompt
When an AI assistant participates, our design recommendation is to keep the policy outside the assistant’s free-form conversation. The interface can display the task alongside the allowed actions, but the model should not be the sole record of the user’s limits.
A spending policy also needs to survive a restarted session, a model change or a provider failure. Those are engineering requirements that the product team must establish, not benefits automatically inherited from either specification.
Measure understandable authority
A useful smart-wallet evaluation asks whether users can explain their permissions, complete a recovery exercise and identify the limits of the product. Fewer clicks are an incomplete scorecard.
The standards create room for better experiences. Dev.Cooking’s editorial test is whether the implementation helps a person understand the authority they retain, the authority they delegate and the evidence needed to verify both.
