Answer Example

I ensure a seamless user experience by integrating popular wallets like MetaMask using WalletConnect and designing intuitive UI elements for wallet interactions. For example, I implemented a clear step-by-step onboarding process for new users to connect their wallets and verify transactions securely. I also added error handling for failed transactions and provided real-time feedback to users, reducing drop-off rates by 20%. This approach enhances user trust and engagement.
