“Can a self-custodial hardware wallet company become the primary spending interface for on-chain stablecoins without sacrificing user sovereignty?”
Tangem was founded in 2017 as a Swiss hardware company making NFC-based smartcard crypto wallets, competing on self-custody and security. In 2026, Tangem launched Tangem Pay — a virtual Visa card product that allows users to spend USDC on the Polygon network directly from their self-custodial hardware wallet without converting to fiat first. This pivot moves Tangem from a pure hardware/wallet product into embedded finance, integrating KYC (via Paera LLC and Sumsub), stablecoin payments infrastructure (via Rain/Signify Holdings), and a Visa card issuance layer — while explicitly preserving wallet non-custody.
