During the development of Satyra Trips, one of the core challenges was architecting a seamless verification flow that could mimic real-world location proof in a lightweight MVP. Since access to actual GPS-based cryptographic proof or zero-knowledge location attestation was out of scope for the hackathon, we had to create a believable mock Proof-of-Visit system that still reflected the spirit of the protocol. Designing this system required balancing user experience with data integrity — ensuring that even with mock data, the demo captured how verifiable reviews could look in a real deployment.

Another obstacle was integrating dynamic browser interactions with Google Maps' DOM structure. Since we envisioned this as both a standalone mini-app and a future browser extension, identifying stable UI hooks within the Google Maps interface for future real-time detection was complex. We overcame this by modularizing our code and abstracting the verification flow to a component that could work both as a web-based mini-app and a browser extension integration.

Lastly, ensuring review data integrity even in a mock environment (without backend or smart contract support) pushed us to build a lightweight frontend-first data schema that could be extended later to include decentralized storage or on-chain attestation.
