Concordium — Supply Chain & Testnet Infrastructure
We delivered two blockchain projects for Concordium: a supply chain track-and-trace system and a testnet faucet.
Track-and-trace:
- Built a CIS-3 NFT smart contract (Rust) for product tracking.
- Added sponsored transactions so users don’t need to hold tokens.
- Implemented an indexer to track all on-chain movements in real time.
- Shipped a full frontend and Docker-based infrastructure.
Testnet faucet:
- Developed a Next.js faucet with Cloudflare Turnstile bot protection.
- Added per-address daily limits and balance checks via the explorer API.
- Provided complete documentation for deployment and maintenance.
Outcome:
- Both systems production-ready and actively used.
- 92 combined commits, clean architecture, ready-to-reuse patterns.
This case shows our ability to ship end-to-end blockchain solutions—smart contracts, infrastructure, and UX—in one go.
