WalletConnect Pay Integration Guide for Flutter (via WalletKit)

This guide enables Flutter wallet developers to integrate WalletConnect Pay for processing crypto payment links through reown_walletkit. The integration allows wallet applications to accept and process payment requests from merchants using the WalletConnect Pay protocol.

Important Approach

Study and adapt, don't blindly copy. Before implementing, examine how your existing wallet app handles:

Deep links and QR code scanning
Modal/bottom sheet presentation
State management patterns
