Building a QR code payment generator for Rapid402.
Anyone can create a payment request QR code by entering an amount, asset (SOL/ETH/BNB/USDC), and their wallet address.
When someone scans it, they're taken to a payment page showing the payment details. They sign the payment in their own wallet app, paste the signature into the form, and submit.
Rapid402 verifies the cryptographic signature and settles the payment on-chain to the merchant's wallet.
