Cryptographic digital twins for physical assets. NFC chips + on-chain lifecycle tracking make counterfeits impossible. Verify any product with a tap. Built on Arbitrum.
TAG IT Network is infrastructure for binding physical assets to cryptographic digital twins on Arbitrum. Every product gets an NFC chip programmed with NTAG 424 DNA challenge-response authentication. One tap verifies authenticity, ownership, and lifecycle status on-chain — no app download required.
The system tracks assets through a 7-state lifecycle (NONE → MINTED → BOUND → ACTIVATED → CLAIMED → FLAGGED → RECYCLED), with every state transition enforced by smart contracts and recorded immutably. Use cases span anti-counterfeiting for luxury goods, pharmaceutical supply chain verification, and defense asset tracking.
Counterfeiting is a $4.2 trillion problem. TAG IT makes it cryptographically impossible.
<p>Built and deployed a full-stack admin console on Arbitrum Sepolia with live contract interaction, lifecycle state management, and asset verification. Developed a mobile NFC scanner app (ORACULAR) using Expo SDK 52 for tap-to-verify authentication. Implemented TAGITCore smart contracts with on-chain lifecycle enforcement and custody transfer events. Created a real-time event feed powered by Goldsky indexing with RPC fallback. Programmed physical NTAG 424 DNA chips and mapped demo items (pharmaceuticals, certificates, cosmetics) to on-chain digital twins for a live 3-minute demo.</p>
<p>Pre-seed. Raising $250K on a SAFE (Simple Agreement for Future Equity) with a $2-3M valuation cap and 22% discount. Funds will accelerate mainnet deployment, security audit, first enterprise pilot, and team buildout. Currently bootstrapped by founder. Actively seeking RWA-focused investors and ecosystem grants from Arbitrum Foundation.</p>
