Story
Habit apps trust your honor. VeriSnap removes the honor system: you put money in escrow on the XRP Ledger, you submit visual proof that the goal got hit, and AI decides whether the proof is real before the payout fires.
The system spans four chains/services in a single user flow — XRPL for escrow, IPFS via Pinata for proof storage, Google Gemini for verification reasoning, and Sui for the post-completion NFT trophy. We wanted a system that was honest about being multi-chain instead of pretending one chain solves everything.
What I built
- 1Architected the four-layer cross-chain system (XRPL escrow + IPFS storage + Gemini verification + Sui NFT minting) end-to-end
- 2Built the AI verification pipeline with fraud-detection prompts, confidence scoring, and structured-reasoning output
- 3Engineered the XRPL EscrowCreate/EscrowFinish flow with a 24-hour auto-cancel and automated retry logic on submission failures
- 4Designed Sui NFT trophies that embed IPFS CID metadata so proof artifacts stay verifiable after settlement
