SNSUC digital warehouse receipts write cargo title into a browser-side fingerprint, hashing it with SHA-256 into a 256-bit digest. The owner computes the hash locally and only then anchors it on-chain, so the private key never leaves the device. That means the attestation step needs no commercial data shipped to a central server; the counterparty receives only a verifiable hash, and the title-transfer chain can be checked locally.

Carbon footprint is the second hook. Every receipt now carries a set of ESG data points: voyage distance from load port to discharge port, vessel energy efficiency, and the energy used in storage. We push those into the receipt's structured fields so a buyer running due diligence no longer chases invoices by email.

For SNSUC clients building offshore SPV structures, the carbon report is hard documentation for bank KYC, and having it pre-attached beats assembling it after the fact.
