Tangem has unveiled Tangem Pay, a non-custodial spending account integrated into its wallet, allowing users to hold USDC on-chain and spend via a virtual Visa card while maintaining control of their private keys. The service, which emphasizes self-custody, is set to launch this month with a goal of reaching 10 million active users by the end of next year. Tangem Pay utilizes NFC-based hardware, such as rings and cards, for seamless one-touch transactions, eliminating the need for mnemonics and complex interfaces.
