Web3 interactions often require routine actions that can feel high-risk to users. This talk explores how wallet connections, approvals, and signatures create risks that can be misinterpreted by users, and how current design patterns fail in adversarial environments.
For many users, the most dangerous moments in Web3 don’t feel dangerous at all, and the least dangerous moments can feel quite intimidating. Core actions—connecting a wallet, approving token access, signing a message—mirror familiar Web2 interactions, yet carry fundamentally different consequences.
This talk draws on real-world user behavior observed through hands-on work supporting self-custody users, including cases involving phishing, wallet compromise, and recovery. These patterns reveal that what appears to be “user error” is often a predictable outcome of how current systems are designed.
Rather than attributing blame to individuals, the talk reframes these incidents as a structural mismatch between human intuition and adversarial environments. It explores how permission models, transaction abstraction, and interface design obscure meaningful risk, making harmful actions indistinguishable from legitimate ones.
