Geneva, Switzerland — May 21, 2025 — WISeKey International Holding Ltd ("WISeKey") ((SIX: WIHN, NASDAQ:WKEY), a leading global cybersecurity, blockchain, and IoT company, in partnership with its subsidiary, SEALSQ Corp (NASDAQ:LAES), which focuses on semiconductors, PKI, and post-quantum technology products, today announces the launch of  new enhanced WISe.ART marketplace, a revolutionary Web3 platform for digital art, digital twins, NFTs, and crypto collectibles. This next-generation marketplace is one of the first and largest of its kind.

The WISe.ART 3.0 platform redefines the digital art experience by providing creators and collectors with a secure, traceable, and intelligent environment for trading and authenticating digital assets.

Key Features of WISe.ART 3.0:

• Native Web3 support: Users can securely and easily connect their Metamask or Walletconnect wallet to the platform. NFTs can be imported and exported to the marketplace to allow complete control of their digital collection.
• Refreshed platform & Multi-Device support: The WISe.Art platform has received a complete overhaul of its front-end and back-end structure, allowing users to carry their digital collection with them at all times, as the new platform supports desktop, tablets and mobile devices.
• Link Between Physical and Digital Assets: WISe.ART NFTs are irreversibly connected to their corresponding physical objects, ensuring tamper-proof authenticity and provenance.
• Smart Contracts for Monetization: Artists and creators can set automated royalty structures, usage rights, and monetization strategies through embedded smart contracts.         
• Advanced Cybersecurity & Post-Quantum Resilience: Secured by WISeKey's and SEALSQ's digital identity and encryption technologies, the platform safeguards all transactions and digital interactions against present and future cyber threats.
• Easy purchase with Crossmint support: The Crossmint integration allows for seamless transactions with credit and debit cards, Apple and Google Pay, from anywhere in the world. Users that do not possess a wallet can create a ghost wallet on-the-fly upon checking out.

For Version 3 we have listened to our users and have added important new functionalities which they requested:

• Collectors and artists can now import pre-minted NFTs from other platforms as long as they are minted in the crypto we support (such as Hedera, Polygon or Eth) and that the pre-minted NFTs are compatible with our requirements. Those wishing to consolidate their NFT collections into one wallet - it can now be done on WISe.ART. Additionally, artists wishing to leave a certain platform can now join WISe.ART and showcase their complete collections on one platform safely and efficiently.
• Relisting tokens on the secondary market is still possible but for those who do not have a compatible wallet, it can be created with few simple steps, new prices can be set as the market fluctuates.
• The user journey for artists and collectors is made simple and intuitive. New FAQ or contact request forms have been integrated for those who seek human interaction. Our white glove service is enhanced throughout the process.

Revolutionizing the Future of Art

WISe.ART 3.0 is democratizing digital expression by empowering billions of people worldwide to create, share, and monetize their artistic visions through a secure and trusted platform. Whether it's a digitally generated painting, a collectible tied to a physical sculpture, or a new form of cultural expression, WISe.ART enables creators from all backgrounds to participate in the global digital art economy, safely and transparently. A new physical space will open Geneva to represent WISe.ART digital works on May 22. This space aims to bridge the 19^th and 21^st Century technologies raising awareness among collectors. The showroom will be a case study for the web3 communities to mingle with their cultural heritage.

Accessible Art Purchasing — Crypto Optional

To acquire WISe.ART digital artworks, including those linked to NFTs or hosted on blockchains, cryptocurrency is not a requirement. NFTs are available for purchase in USD and other fiat currencies, and transactions can be completed securely via credit card, debit card, Apple Pay or Google Pay. Additionally, Crossmint facilitates the conversion of fiat money to crypto for users who wish to engage in blockchain-based purchases. While collectors of blockchain-based works typically need a crypto wallet, platforms such as Metamask and WalletConnect make wallet setup simple, intuitive, and user-friendly, enabling purchases with the ease of acquiring a traditional artwork.

Carlos Moreira, Founder and CEO of WISeKey, stated: "Since inception the platform has welcomed an eclectic array of works representing all types of art from physical pieces coupled with digital twins, numeric compositions, ai assisted or generated art, music and film as well as collectibles like real estate, jewelry and design. As technology progresses, we attract artists who are keen to explore the new possibilities and means to convey their message. Technology is a tool - art is a vector for communication."

WISe.ART 3.0 opens the door to a future where creativity meets accountability, and where digital assets are as protected and valuable as their physical counterparts. For more information, visit www.wise.art
