non-fungible tokens
financial
“enables Non-Fungible Tokens to be provisioned directly into secure semiconductor chips”
A non-fungible token is a unique digital certificate, stored on a blockchain, that proves ownership and authenticity of a specific digital item or a limited physical asset—think of it as a one-of-a-kind trading card or a deed for a piece of art. It matters to investors because it creates markets for scarcity and exclusive rights, with value driven by rarity, demand and transferable ownership, but it can be volatile and illiquid.
post-quantum cryptography
technical
“secured using SEALSQ’s post-quantum cryptography, meaning WISe.ART-certified works remain”
Post-quantum cryptography is a set of new methods for scrambling data so it stays secure even if powerful quantum computers exist; think of replacing today’s locks with designs that a future high‑speed lockpicker cannot open. For investors, it matters because companies must upgrade systems, meet regulations, and protect customer and trade data—creating costs, competitive advantages, or legal and reputational risks depending on how quickly and effectively they adopt these new security standards.
root-of-trust
technical
“backed by SEALSQ’s Root-of-Trust semiconductor technology”
A root-of-trust is the foundational security element—often a small dedicated chip or protected software module—that ensures a device or system only starts and runs with authentic, approved code and keys. For investors, it matters because a strong root-of-trust reduces the risk of hacks, data breaches, regulatory problems and product recalls, protecting a company’s reputation and value much like a building’s solid foundation and locks protect everything inside.
digital product passport
regulatory
“as a tamper-proof Digital Product Passport (DPP), surviving auction houses, estate transfers”
A digital product passport is an online record that stores verified information about an item’s origin, materials, manufacturing, ownership history, certifications and repair or recycling options — like a passport for a physical product. Investors care because it makes supply chains and compliance transparent, helping assess regulatory risk, durability, resale value and brand trust; clearer data can reduce surprises, legal exposure and costs tied to sustainability or safety rules.
microcontroller
technical
“to a SEALSQ secure microcontroller physically associated with the artwork”
A microcontroller is a tiny, self-contained computer on a single chip that runs simple programs to control electronic devices — think of it as the device’s on-board brain that turns inputs (like a button press or sensor reading) into actions (like switching a motor or displaying information). It matters to investors because these chips are essential components in products from cars to appliances and industrial gear, so their availability, cost, and performance can directly affect a company’s production, margins and competitiveness.

WISeKey’s WISe.ART Subsidiary Becomes the World’s First Hardware-Authenticated Art Platform as SEALSQ Subsidiary Secures European Patent for ‘Back-to-Physical’ NFT Technology
EPO-Granted Patent Embeds NFTs Directly into Secure Semiconductors,
Creating an Immutable Chain of Provenance, Ownership, and Authenticity for WISe.ART’s Global Art Ecosystem
Geneva, Switzerland – June 18, 2026 — WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY) (“WISeKey”), a global leader in cybersecurity, digital identity and IoT, today announced that its subsidiary, WISe.ART, the trusted digital art marketplace has become the world’s first hardware-authenticated art platform while its other subsidiary SEALSQ Corp. (NASDAQ: LAES) (“SEALSQ”) that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products has been granted a landmark divisional patent by the European Patent Office (EPO) for its ‘Back-to-Physical’ NFT technology, the foundational IP that enables Non-Fungible Tokens to be provisioned directly into secure semiconductor chips, creating an immutable, hardware-rooted link between a digital asset and a physical object.
For the global art market, this is not an incremental upgrade. It is a structural breakthrough: the first time that artwork provenance, ownership history, and authenticity certification can be cryptographically sealed at the silicon level, permanently, independently verifiable, and resistant to quantum-era threats.
The Provenance Problem the Art World Has Never Fully Solved
Forgery, disputed attribution, and opaque ownership chains cost the art market billions annually. Blockchain-based NFTs represented a genuine step forward, yet they remain fundamentally software constructs: a token on a ledger is only as trustworthy as the platform maintaining it. Platforms can be shut down. Tokens can be disputed. The link between a digital certificate and a physical work remains unenforceable at the hardware level.
WISe.ART was founded to solve this problem at its root.
What the EPO Patent Grants
The newly granted EPO divisional patent covers SEALSQ’s core ‘Back-to-Physical’ claims: the method by which an NFT is provisioned directly into a tamper-proof semiconductor, creating a unique, cryptographically secured digital identity permanently embedded in the physical chip. The patent portfolio now spans three jurisdictions:
- Swiss Priority Filing: CH 070467/2021 — Filed 29 October 2021 — foundational priority
- European Patent: EP 22200142.2 / EP 4174706 A1 — Granted — divisional covering Back-to-Physical core claims
- US Application: US 17/514,296 / US 2023/0139878 A1 — Pending at USPTO
- Further EPO Divisional: Under examination — Additional claims in prosecution
What This Means for WISe.ART and Its Ecosystem
WISe.ART is the only art platform in the world whose provenance guarantee rests on a granted European patent, backed by SEALSQ’s Root-of-Trust semiconductor technology. In practice, this means:
- Hardware-Anchored Authenticity: Every work certified through WISe.ART can carry an NFT anchored not merely to a blockchain record, but to a SEALSQ secure microcontroller physically associated with the artwork. The chip is the certificate.
- Immutable Digital Product Passport: Creation details, ownership history, exhibition records, valuation events, and transfer documents travel with the artwork forever as a tamper-proof Digital Product Passport (DPP), surviving auction houses, estate transfers, and generations of collectors.
- Post-Quantum Cryptographic Protection: The entire trust architecture is secured using SEALSQ’s post-quantum cryptography, meaning WISe.ART-certified works remain cryptographically authentic even as quantum computing matures, a durability no software-only NFT platform can offer.
- Decentralised Verification: An artwork’s authenticity can be independently verified by anyone, anywhere in the world, without relying on a central server, a third-party database, or the continued operation of any single platform.
- Regulatory Readiness: The DPP framework aligns directly with emerging European regulations mandating Digital Product Passports across high-value industries. WISe.ART-certified artworks will be compliant by design.
Carlos Moreira, Founder and CEO of WISeKey noted, “WISe.ART was built on the conviction that trust in art cannot be a software promise, it must be a hardware guarantee. Today’s EPO patent grant transforms that conviction into protected intellectual property. For the first time, collectors, institutions, and artists have access to provenance that is not only blockchain-recorded but silicon-sealed, post-quantum secured, and independently verifiable without any centralized authority.”
The WISeKey / SEALSQ Trust Infrastructure
WISe.ART operates within one of the world’s most comprehensive digital trust ecosystems. WISeKey has spent 25 years building a global PKI and Root-of-Trust infrastructure now trusted by over 2.6 billion devices. SEALSQ develops and deploys the post-quantum secure microcontrollers and certified semiconductors that underpin this infrastructure.
The same silicon-level trust that authenticates aerospace components, medical devices, and satellite payloads now protects art. WISe.ART is the creative economy’s access point to infrastructure-grade provenance.
