About
Payce is a project that enables users to send USDC to anyone in the world using just their phone number, and allows recipients to spend their crypto instantly via Apple Pay. A fresh wallet is created using Privy and linked to the phone number, then funded by sender. The sender covers the gas via a Sponsor Wallet, so the recipient doesn’t need any native tokens. The recipient is notified by SMS with a magic link to claim their funds. No apps to install, no seed phrases to manage, just a seamless crypto experience, as easy as sending a text.
How it's made
For this project, we used: - Next.js for the web app, with ShadCN UI components and Tailwind CSS for a clean and responsive frontend - Textbelt to handle SMS delivery and OTP verification - Privy for account abstraction and seamless wallet creation mapped to the user’s phone number - Mantle as our L2 blockchain for fast, low-cost, and gasless USDC transfers This stack allowed us to create a smooth and intuitive UX, accessible even to non-crypto natives.
