Plasma One Sign-In Outage Left Card Spending Available to Users

An outage at the external service Plasma One uses to verify sign-ins was preventing users from accessing the app at 10:22 a.m. ET Nov. 11. Card spending capabilities remained available during the login disruption.

Plasma said the problem affected logins only. The company said balances and card services remained available, with no adverse effects on user funds reported.

Plasma One is the consumer app and Visa debit card from U.K. fintech Plasma. Launched in June 2026, it runs on the Plasma blockchain, which is built for stablecoin transactions, and supports self-custodial wallets for Tether (USDT) and USD Coin (USDC). The app launched first on iOS and later on Android. It also offers biometric authentication options, and account setup requires a government ID and proof of address.

The app provides instant peer-to-peer transfers and yield options through third-party decentralized finance platforms. Its virtual and physical Visa cards are available for use in more than 180 countries, subject to geographic restrictions.
