SNSUC's digital warehouse receipts move title confirmation into the browser. Each receipt is hashed client-side with SHA-256 into a 256-bit digest; the owner signs it with a private key and the record goes on-chain, cutting title transfer from three days to ten minutes.

Receipts map one-to-one to physical stock, with each of the 13 categories carrying its own serial, which rules out double-pledging the same cargo. On the ESG side, carbon footprint is captured lot by lot from refinery to port, with per-unit energy use and emission factors written on-chain so buyers skip the dozen PDFs normally required for due diligence.

For transshipment deals, the setup hardens bill-of-lading authentication and third-party inspection certificates into verifiable records — banks see proof, not promises.
