Challenges I 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.
