Read the asset, not just the balance
A displayed token or collectible belongs to a particular type and package. Copying a name or logo is easier than reproducing the authentic issuer's identity. Review the application package, upgrade arrangements and permissions involved in an action.
A wallet interface may summarise a complex transaction. The useful question is which objects, assets and authorities change if it succeeds. A label such as claim or verify does not determine those effects.
Claims about programming-language safety should be scoped to the properties actually enforced. Economic design, phishing, compromised websites and misleading promotion remain separate problems. See signing intent and token identity.
