Inspiration

International money transfers remain slow, opaque, and expensive; especially for freelancers, SMBs, and families sending funds abroad. We wanted to create a platform that removes the technical and financial friction behind cross-border payments by combining the transparency of fintech with the speed of blockchain aggregation, without exposing users to crypto complexity.

What it does

Warp is a web-based fiat-to-fiat transfer app that guarantees users the best real-time exchange rate. It compares live rates from centralized and decentralized exchanges, models transaction batching to save gas fees, and displays full transparency between our rate, the mid-market rate, and competitor rates. The result: faster, cheaper, and more transparent international transfers, powered by a next-generation quoting engine.

How we built it

We built a FastAPI backend integrated with: Live FX APIs (exchangerate.host) Crypto liquidity APIs (Coinbase, 1inch, zkSync, Polygon) Firebase Authentication and Firestore for secure user management and transaction logs The React frontend was designed with GSAP-based animations, a sleek dark theme, and real-time API handling.

Challenges we ran into

We spent a large portion of our time attempting to integrate with Stripe's API for our demo, but in the end, the process required too much verification and real financial data from us, so we were unable to perform a fully functional P2P solution in 24 hours, but I think we made a great proof of concept with real, real-time data.

Managing async API calls and aggregating multiple live quotes simultaneously Designing a secure, trust-centric experience that hides blockchain complexity Integrating Firebase transactions atomically while maintaining accurate balances and history

Accomplishments that we're proud of

Built a fully functional multi-API quoting engine that proves real-world rate superiority Created a clean, production-ready UI/UX with seamless animations and intuitive flow Demonstrated transparent rate comparison — turning latency into a unique user trust feature

What we learned

We learned how to combine live fintech data aggregation with blockchain routing logic, manage concurrent async operations in Python, and design financial products that build user confidence through transparency and security rather than jargon.

What's next for Warp

We plan to:

Integrate with Stripe and circle once our accounts are verified. Expand to mobile (React Native) Add real transaction execution with stablecoin settlements Implement automated compliance (KYC/AML) and deeper liquidity routing Launch beta testing for freelancers and SMBs across LATAM and Southeast Asia
