Transfer-trade funding stalls on one warrant, many checks: the same digital warrant for a cargo gets reviewed by the issuing bank, the financing bank and the custodian bank, each redoing KYC and title verification, dragging T+0 negotiation to T+2 or worse. SNSUC now hashes the warrant's fingerprint with SHA-256 and turns it into a three-bank trusted warrant.

The mechanism is plain. At warrant creation, title, quantity and the warehouse's signature are hashed once; the fingerprint goes on-chain with a timestamp. After the issuing bank finishes first-pass diligence, it anchors the verification conclusion to that fingerprint; the financing and custodian banks read the same fingerprint and accept it, no re-check. A 50,000-tonne crude warrant moves from many round trips to one fingerprint match, and funds land the same day.

This design answers Rule F9 head-on: back-to-back letters of credit and offshore transfers draw heightened bank scrutiny, so the answer is deeper diligence, not looser process. Cross-bank recognition does not cut steps; it changes repeat the work into do it once, many accept, satisfying the bank's look-through requirement while letting SNSUC's transfer cash cycle actually reach T+0.
