From unique identity to compliance-ready data, SealTrust covers the five layers that make a product verifiable, traceable, and trusted throughout its lifecycle.
Cryptographic NFC tags or QR codes give each product a unique identity. Tap or scan to verify, no app required. This is the foundation of the Identity and Proof layers.
On-chain NFT certificates and metadata stored on IPFS provide proof of origin, authenticity, and ownership. The hash and the anchor stay public on Base even if SealTrust disappears, and you can export your catalogue, your passport payloads and the anchoring proofs at any time, to re-host them elsewhere, with no vendor lock-in.
SDM analysis and the anti-replay counter refuse a replayed URL on every scan, inline. Each scan strengthens the product's trust score through continuous proof verification.
Secure peer-to-peer ownership transfer with full on-chain history. Supports resale, warranty activation, and post-sale engagement workflows.
Structured product data aligned with EU ESPR requirements. Materials, origin, repairability, and lifecycle events in a compliance-ready format.
Monitor serialization, scan activity, security alerts, and product lifecycle events. Built for teams managing authentication at production scale.
A built-in assistant answers questions about products, passports and authenticity, on sealtrust.io and inside your admin console, grounded in our documentation and citing its sources.
Add a product's passport and certificate to Apple Wallet or Google Wallet, so the proof of authenticity travels in the owner's phone.
Export and ingest lifecycle events (manufacturing, repair, recycling) in the GS1 EPCIS 2.0 standard, for interoperable traceability across the supply chain.
How it works
From factory floor to customer scan in three steps. No app install, no crypto wallet, no training required.
A unique cryptographic NFC tag or QR code is encoded and applied to your product. NFC chips generate a different dynamic code on every scan; QR suits high-volume lines.
An NFT certificate is created on the blockchain and metadata is stored on IPFS (decentralized storage). This digital identity is permanent, verifiable and tamper-proof.
The customer taps the NFC tag or scans the QR code with their smartphone. Authenticity is verified instantly by cross-referencing the cryptographic data with the blockchain certificate.
How we secure each product
Two ways to prove a product. Cryptographic NFC chips carry an AES-128 key that stays inside the chip, for the strongest guarantee, and a replay is refused on every scan. QR codes suit high-volume lines, with a short serial bound to the blockchain certificate and to the anchored passport, which anyone can re-check.
Fits into what you already run
REST API, webhooks, batch endpoints. Connect to your ERP, CRM, or e-commerce backend without replacing anything.
Complete RESTful API to integrate authentication into your business workflows: ERP, CRM, e-commerce.
Real-time notifications for every event: scan, verification, transfer, security alert.
Encode and certify hundreds of tags in a single operation for high-volume production runs.
Manage multiple brands and product lines from a single account with granular permissions.
From product registration to resale, every step is authenticated and written to the product's history; minting and ownership changes also carry a public transaction, verifiable on Base.
We suggest starting with 50 to 500 tagged products on a single product line. We handle tag provisioning, blockchain setup and onboarding, and a first line can go live in about two weeks.
