I built a blockchain-based supply chain tracker that makes it impossible to fake where a product has been — looking for brutal honest feedback
I'm a student developer from Nepal and I just finished building BlockTrack — a SaaS platform that records every step of a product's supply chain permanently on the blockchain.
The problem it solves:
Right now, companies track shipments using Excel sheets, emails and PDFs — all of which can be faked. There's a $500B counterfeit goods problem, food safety recalls that take 7 days to trace (people die), and customs disputes where both sides have different "records."
What BlockTrack does:
Every time a product moves hands (factory → shipping → customs → warehouse → retailer), that checkpoint is recorded permanently on the blockchain
Nobody can go back and change it
Anyone can scan a QR code and see the full verified history of a product
Built on Polygon (cheap gas fees, fast transactions)
Current tech stack:
Next.js frontend
Node.js/Express backend
Supabase database
Solidity smart contract deployed on Polygon Amoy testnet
What I'm trying to figure out:
Would a mid-size pharma company, food brand, or electronics importer actually pay for this?
What's the #1 feature missing before this becomes sellable?
Has anyone here dealt with supply chain fraud or traceability problems in their business?
Is there anyone who'd want to pilot this for free in exchange for feedback?
I know enterprise security features (per-company logins, role-based permissions, audit logs) are missing — that's my next sprint. I just want to know if I'm building something people actually want before I spend another month on it.
Happy to share the GitHub link or demo video if anyone's interested.
Brutal honesty welcome — what am I missing?
