From February 2027, EU Battery Regulation obligations start biting: battery passports, due-diligence records, recycled-content declarations. MRV reporting and anti-counterfeit digital product passport requirements are moving the same way. VeriV gives every batch a tamper-evident digital passport your customer can check with one tap of a phone — no app, no login, no trust required.

Provenance and purity arrive as a PDF assay and a supplier's word. Neither survives a serious audit.
A printed code can be photographed and reprinted onto anything. A copied code verifies exactly as well as the original — which means it verifies nothing.
Custody history sits across emails, spreadsheets and warehouse systems, with no single record anyone downstream can inspect.
February 2027 is not far away, and compliance evidence has to be collected before that date, not reconstructed after it.
Opacity used to be an inconvenience. It is becoming a market-access problem.
VeriV is a protocol and framework for chain of custody, traceability, trust and accountability. It combines the digital footprint — cryptographically signed records — with the physical asset itself, so the object in front of you and the evidence behind it are one verifiable thing, not two separate claims.
Applied to industrial materials — vanadium, molybdenum, cobalt, nickel, tungsten and titanium — that means every batch carries a digital product passport anchored to a secure NFC tag. Tap it with any modern smartphone and the passport opens: where the material originated, what the assays say, who handled it and who signed for it, and whether every record still holds up cryptographically. Mine to grid and back again.
One tap. No app to install. The person checking does not need an account, and does not need to take your word for anything.
Three independent layers have to agree before a batch verifies.
Every tag is built on the NXP NTAG 424 DNA, a secure chip with an AES-128 cryptographic engine on board. Each tap produces a fresh, one-time code that is useless the moment it is used. Copy the tag's printed surface and you copy nothing that verifies.
Every assay, custody handover and shipment record is signed using ECDSA-P256 digital signatures under ISO/IEC 20248:2022. Alter a single character and the signature stops matching. The signature can be checked independently — by your customer, your auditor, or a regulator.
The pipeline runs from batch initiation through source assay, processing, purity certification, logistics and end-of-life recovery. Every stage is signed off by a named person who is accountable for it. AI is used to assist analysis — flagging variances for review — and never signs anything. Humans sign.
Verification runs serverless on AWS against an append-only ledger: records are added, never overwritten. Information security is managed against ISO 27001 as a roadmap commitment.
Spent refinery catalyst is tracked from source assay through recovery to certified purity, so recovered metal enters the market with documented provenance instead of an unverifiable claim.
Cell and pack passports built for EU Battery Regulation obligations landing in February 2027 — recycled content, due diligence and custody history captured as you produce, not reconstructed under deadline.
Examination results issued as signed records, so any post-issue alteration is detectable by anyone checking — with optional NFC-sealed custody for the physical paper trail.
Signed, tamper-evident credential records that an employer or registrar can verify in a tap, without contacting the issuer.
VeriV is built on published standards, with the people who wrote them.
Carbon wallet: coming soon.
Compliance evidence has to be collected as material moves, not assembled afterwards. We are running a small number of pilot conversations now — a short discussion of your material flow, your reporting obligations, and what a first tagged batch would look like.
