WHY
Trust shouldn’t be a screenshot. Verified history, zero doubt.
The challenge: compliance, risk, and trust
Buyer Hesitation
Without verifiable history, confidence collapses at checkout; disputes and returns rise.
Transactional Risk
Unverified grading and repair data stall intra-vendor trading and financing, slowing cycles and eroding margins.
Fragmented Data
Trust is trapped in silos—grading suites, ERPs, and marketplaces speak different standards. No portable reputation layer.
Regulatory Pressure
DPP raises the transparency baseline; claims must be backed by verifiable lifecycle evidence. Starting 2027, EU DPP/ESPR expects verifiable lifecycle data.
What DeviceStamp brings
Compliance by Design
Immutable data trail aligned with EU DPP architecture; selective disclosure; securly stored evidence with on-chain anchors.
Cross-Platform Interoperability
Open schema, GS1-ready, exportable JSON-LD for seamless exchange across grading tools, ERPs, service networks, and marketplaces.
Audit & Enforcement Readiness
Regulators or partners can independently verify any claim—no vendor mediation required.
Circular Economy at Scale
Built for 250M+ events/year; reuse histories become value-adding assets fueling the circular market.
Boosting consumer trust
Instant trust, zero complexity
67% of shoppers abandon carts; when device claims are verifiable, hesitation drops. A listing badge (e.g., marketplace PDPs), one-click verification, and tamper-evident records (IPFS CIDs) reduce doubt and drive conversion.
Seamless verification UX
Start with a hosted Verify page, then embed the Verify Widget for PDP-level checks—no overhaul required.
How it works
Immutable Data Anchoring
Grading results, photo hashes, wipe logs, and repair events are anchored on an EVM-compatible L1.
Audit-Grade Permanence
Artifacts are content-addressed (IPFS); on-chain links ensure verifiability and retrieval integrity.
Smart-Contract Authenticity
EIP-712 typed-data; each record emits a verifier-consumable proof.
Neutral Governance
Infrastructure-only—never any channel conflict. Built for industry-wide adoption.

Service tiers
Essential Tier
On-chain: hash. Evidence: documents via IPFS. Retention: 10 years. Core compliance for long-term auditability with immutable anchors and content IDs.
Advanced Tier
On-chain: hash. Evidence: documents and photos up to 10 MB. Retention: 2 years. Stronger verification for returns, warranty claims, and trade-ins.
Max Tier
On-chain: hash. Evidence: documents and photos. Retention: 10 years in Glacier. Premium protection suited for forensic audits and long-tail disputes.
Custom Security Setup
On-chain: hash. Evidence: your documents remain vendor-hosted. Verification: content hash with CID. Keep inspection docs in your infrastructure while enabling public authenticity checks.
Security & compliance
GDPR & DPP Compliant
Aligned with EU privacy and DPP structures; future-proof for 2027+. Anchors provide integrity without data relocation.
PII-Safe by Design
No personal data on-chain—only cryptographic fingerprints. Privacy preserved; proof intact.
Open Portability
OEM/GS1 interoperability; data remains verifiable, migratable, and vendor-neutral across partners and systems.
PLAN B – Redundancy
IPFS + Glacier dual storage ensures nothing is lost; full-hash restores are verifiable and time-bounded.
Security Architecture
EIP-712 typed-data; deterministic hashing; whitelisted wallets; distributed token authorization; immutable audit trail.
Choose your path
Software vendors (grading/testing/wiping)
Embed the lightweight SDK; your software stays the hero. DeviceStamp adds verifiable proof to every action via typed events and anchors.
Operators & enterprise fleets
Run a 10k-device pilot to quantify resale uplift, reduce disputes, and validate DPP readiness. Minimal change management; evidence stays vendor-hosted.
Marketplaces
Show buyers and auditors verifiable condition and wipe integrity at the PDP. Start hosted, then embed the Verify Widget.
Spare-part distributors
Validate part origin and test lineage at receiving/QC. Compact proofs travel with components for partners, insurers, and OEMs.
NGOs & regulators
Audit vendor-independent lifecycle evidence. The schema maps to DPP/ESPR fields; read-only access available.
Importers
Attach verifiable provenance and compliance evidence and build trust in the market. Prepare for EU DPP requirements as importer.
