Zug, Switzerland, May 28th, 2025 – Tangem, a Swiss manufacturer of crypto hardware wallets, has announced it has secured its third U. S. patent (No. 12307443) for a blockchain-enabled smart ring, officially marking the company’s entry into the rapidly expanding wearable finance market. The patented smart ring allows users to securely store cryptocurrency keys and sign blockchain transactions simply by bringing the ring close to a smartphone. Featuring a secure chip that performs cryptographic signing internally, the device ensures private keys remain protected and never exposed—an essential security aspect confirmed through the patent process. Tangem is also developing contactless crypto payment features directly from the ring, aiming to combine ease of use with self-custody in a wearable format. “This patent validates our secure architecture and positions Tangem as a leader in wearable finance, ” said CEO Andrey Kurennykh.

“We are building a platform to make decentralized finance more accessible without sacrificing security or user control. ” This is Tangem’s third U. S. patent in 2025, with earlier patents covering a private key backup system and a crypto payment card that integrates secure self-custody with everyday transactions. Tangem’s growth arrives amid the smart ring market’s continued double-digit CAGR, fueled by consumer interest in wearable payment and identity solutions. The company anticipates substantial opportunities in licensing, embedded finance partnerships, and direct-to-consumer sales. “The Tangem Ring embodies a long-term vision of merging cryptographic integrity with practical daily usability, ” Kurennykh added.
