Most people use WalletConnect as a QR code scanner; what truly decides retention and reputation is 'authorization granularity + revocation experience + understandable risk'. The ideal state resembles browser permissions: minimum authorization, time limits, cross-device awareness, and one-click revocation at any time; render a human-readable summary before confirmation—how much will be spent, which contract, what permissions will be invoked, and when it expires. Turn 'invisible security' into UI copy and switches that everyone can understand.
Multi-account/multi-device scenarios, using session keys + scope isolation combined with device binding and white/black lists; high-risk operations limited to specified devices and time periods; DAO/small teams separate initiation, review, and limits, forming an auditable internal control chain. In case of anomalies, a unified entry revokes all sessions and broadcasts, reducing the tail risk of authorization loss of control.
Practical checklist: ① Establish a 'minimum permission package' and check it by default; ② Design a revocation priority path (entry always visible, two steps to complete); ③ Enable domain binding and transaction simulation to reduce mis-signing; ④ Output authorization receipts (domain, permissions, amount, expiration) for easy post-sale review. Security is not about increasing complexity, but reducing cognitive burden—when revocation is easy and information is symmetrical, users will naturally take an extra step.
