Beyond Simple APIs: Why Web3 UI Development Requires Rethinking State and Verification

Web3 UI development transcends traditional data-fetching patterns because transactions depend on external, asynchronous blockchain processes—wallet confirmation, network consensus, and block mining—that developers cannot control. This fundamental shift means building interfaces that tolerate uncertainty and handle state convergence rather than instant updates. The critical insight: Web3 transactions sent to incorrect addresses don't fail gracefully like backend API errors; they succeed silently elsewhere, making address verification and transaction confirmation essential safeguards against irreversible loss.
