Gnosis Pay breach exposes card numbers, home addresses and linked crypto wallets

Gnosis Pay suffered a data breach that exposed users' card numbers, home addresses and linked crypto wallets, with one user noting the leak ties his home address and card number to every wallet connected to his account. The incident raises the risk of targeted phishing and scams, since attackers can now correlate onchain wallet activity with real-world identities and physical addresses. The breach matters because Gnosis Pay bridges traditional card payments and self-custodial crypto accounts, so leaked links between the two could undermine user privacy across both. What to watch next is how many of the platform's users were affected, whether Gnosis Pay discloses the scope and root cause, and whether it adds protections such as card replacement or wallet unlinking.
