Inspiration
L.A.R.P was inspired by the difficulty of verifying “Made in Canada” claims in complex procurement supply chains. We wanted to help purchasers move from self-declared claims to evidence-backed verification.
What it does
L.A.R.P verifies drone procurement provenance. Suppliers create signed attestations, and purchasers can see the product’s chain, Canadian-content percentage, designation, and flagged issues.
How we built it
We built a verification backend with supplier and purchaser workflows. The system links signed supplier attestations into a chain, checks the claim, calculates Canadian content using a FastAPI based backend, and presents the result clearly using a react based frontend.
Challenges we ran into
Our main challenge was balancing strict verification with a simple user experience. The system needed to catch issues while still being understandable to suppliers, purchasers, and auditors.
Accomplishments that we're proud of
We are proud that L.A.R.P connects technical verification to a realistic procurement workflow. It does not just say whether a claim passes; it helps explain why.
What we learned
We learned about the importance of the user experience. Claims also need to be complete, consistent, and easy for humans to interpret.
What's next for L.A.R.P
Next, we want to expand the supplier registry, improve onboarding, and integrate with inventory and procurement tools. Longer term, L.A.R.P could support defence supply chains and other critical industries.
