Turn a product into an on-chain record whose whole journey — producer, distributor, retailer, customer — is signed and time-stamped by the party holding it at each step. Nobody can quietly rewrite where it's been.
Certificates of origin, chain-of-custody logs and batch records are spreadsheets and scanned paper. Any link in the chain can lose them, backdate them, or forge them — and by the time a dispute reaches a customer or a regulator, there's no independent record to check against.
What's missing isn't more paperwork. It's a shared ledger that every party can write to but none can rewrite.
The producer opens the chain; each subsequent holder signs their own step with their wallet.
A verified issuer mints the item and opens its supply chain — the first, signed entry. Origin is cryptographically tied to a vetted organisation, not a typed-in name.
The current holder signs a short entry — who has it now, where, and any note — before it moves on. The signature proves it was really them.
The final step marks delivery and locks the chain. From then on it's a permanent, public timeline anyone can read by scanning the item.
Entries are append-only and signed. Reordering or editing history breaks the signatures — visibly.
Only the wallet that issued the item can open its chain, and only while it's an active verified issuer.
Customers, auditors and regulators scan a code and read the full journey. No login, no gatekeeper.
Same hashing, signing and verification as the rest of TrueChain — nothing bespoke to maintain.
Mint a tracked item as a verified issuer, or follow one that already exists.
