How it's made
Challenges we ran into **🧠 AgentKit Integration** Integrating Coinbase AgentKit wasn’t plug-and-play. **We built custom action providers** that combined LLMs and blockchain logic, enabling AI to verify secure, real P2P marketplace transactions. Lots of 🔁 testing ensured onchain accuracy. **🔐 Secure QR Code Handling** OXXO Spin QR codes = real money 💵. **We implemented end-to-end encryption** — QR data is encrypted client-side and only accessible to verified parties. This required building custom cross-stack cryptographic workflows. **🛡️ Escrow Security** We developed a **trustless escrow system** where tokens remain locked until fiat is verified. This required careful Coinbase Agent Kit logic to avoid 🧧 double-spending and **ensure user protection.** **✨ UX for Everyone** We transformed a complex crypto backend into a **simple, intuitive experience** 🧃. No jargon, no confusion — just scan, send, and confirm.
