USD/CNY edged up to 6.7104 (+0.07%), with low volatility supporting settlement stability for SNSUC’s cross-border petroleum product trades; enhances alignment between blockchain-verified documentation and FX execution windows.

SNSUC's traceability stack uses a browser-side SHA-256 fingerprint as the verification entry point: a buyer needs to trust no intermediary, recomputing hashes for the warehouse receipt, inspection report and bill-of-lading elements locally and comparing them with the on-chain anchor. Covering thirteen operating categories and seven crude re-export grades, it turns title verification from a paper relay into a single, independently recomputable check.
