Gnosis Pay, a service enabling stablecoin spending via Visa debit cards, reported a data breach on November 6, 2026. The company identified unauthorized access to its consumer card system on November 3, 2026. Security teams contained the incident within two hours and updated security credentials.
The breach exposed customer details, including names, home addresses, card numbers, and linked wallet addresses. Gnosis Pay stated that the affected system was scheduled for retirement on December 20, 2026. The company's enterprise white-label platform remains unaffected by the incident.
In response, Gnosis Pay mandated 3D Secure verification for online payments and increased fraud monitoring. The company warned users that stolen data could facilitate targeted phishing attempts. The incident follows recent major industry security events, including a $6 billion hack at Binance and a $40 million loss at Mercado Bitcoin.
