We build the infrastructure for cryptographically verifiable trade — mapping EPCIS events to Verifiable Credentials, binding DIDs to supply chain actors, and embedding HS Codes, INCOTERMS®, and UCP 600 as normative vocabularies so every shipment becomes a self-proving trade document.
VSC is a five-layer architecture that transforms physical supply chain events into self-contained, cryptographically provable trade documents. It maps EPCIS events to Verifiable Credentials, binds DIDs to supply chain actors, and embeds three normative vocabularies — HS Codes, INCOTERMS®, and UCP 600 — so a single credential answers what the product is, who bears commercial risk, and how payment is governed.
📋
EPCIS → VC Mapping
Lossless transformation of all five EPCIS event types into Verifiable Credentials with Data Integrity proofs. Every event becomes tamper-evident.
🔐
DID Identity Binding
Every credential signed by the asserting actor's DID. Verifiers resolve DIDs independently — no central authority required.
📦
Normative Vocabularies
HS Codes for commodity classification, INCOTERMS® for commercial terms, UCP 600 for trade finance. All standardized, all machine-readable.
Reusable, public credential schemas tailored to specific industry regulatory contexts.
