Inspiration
We were inspired by a trust gap in vehicle damage assessment: users receive estimates, but there’s no tamper-proof proof of what was assessed, when, and by whom. We saw Solana as the perfect foundation to add transparency, speed, and verifiability to insurance and repair workflows.
What it does
Opticar is an AI damage assessment platform with on-chain proof:
- Detects part + damage severity from vehicle images
- Produces a CAD line-item estimate and roadworthiness guidance
- Generates technical repair recommendations
- Anchors assessment integrity on Solana Devnet (hash + memo + signature/explorer link), so results can be independently verified
How we built it
- FastAPI backend + frontend dashboard for upload, analysis, and reporting
- Detection + pricing pipeline for structured, deterministic estimates
- LLM layer for meaningful safety/roadworthiness reasoning
- Solana attestation module to:
- Hash response payloads
- Submit memo-style attestations on Devnet
- Track status (pending/submitted/confirmed/failed)
- Expose explorer links and verification actions in UI
Challenges we ran into
- Designing a clean flow between AI outputs and blockchain submission states
- Handling async blockchain confirmation without blocking user experience
- Making attestations useful to non-crypto users (clear status + simple verify UX)
- Ensuring reliable fallback behavior when external services are unavailable
Accomplishments that we're proud of
- We shipped an end-to-end AI + Solana workflow, not just a concept
- Every assessment can be tied to a verifiable on-chain artifact
- We built a live attestation dashboard and verification controls
- We made blockchain trust benefits visible in a practical, real-world product
What we learned
- Solana is a strong fit for high-frequency, low-latency trust records
- Verifiability matters most when users can understand it instantly
- Pairing deterministic computation, LLM reasoning, and on-chain attestation creates a powerful trust stack
- Product UX is as important as protocol integration in Web2.5 applications
What's next for Opticar
- Move from Devnet to production-grade Solana deployment
- Add wallet-backed role-based signing (shop/adjuster/insurer)
- Support multi-party attestation and claim lifecycle checkpoints
- Build immutable audit trails for insurance compliance
- Add ZK/privacy-preserving options for sensitive vehicle and owner data
