Coinbase Says Customer Funds Remain Safe After Amplitude Data Exposure

Coinbase said on October 28, 2026, that a security incident involving third-party analytics provider Amplitude exposed some customers’ contact information. The cryptocurrency exchange emphasized that its internal systems were not breached and customer funds remain secure. The company has not disclosed the exact number of affected users or the full extent of the exposed information.

The incident originated outside Coinbase’s infrastructure, highlighting security risks associated with external technology providers. Amplitude provides analytics services that help businesses understand customer behavior and platform activity. Although Coinbase reported no evidence of unauthorized access to its systems, exposed contact details could increase the risk of phishing attempts and fraudulent communications targeting cryptocurrency investors.

Coinbase said it is notifying affected customers and relevant regulators. The company maintains that the incident did not compromise customer assets or its core trading infrastructure. However, the disclosure raises concerns about how cryptocurrency platforms manage sensitive information shared with outside vendors. Users should remain cautious about unexpected messages requesting passwords, verification codes, or cryptocurrency transfers.
