The issue stemmed from Mixpanel, an analytics service used by Koinly. In an email sent to users, the company said the exposure appears limited to email addresses.
It confirmed that sensitive data such as wallets, transactions, tax reports, and portfolio information was not shared with Mixpanel and remains secure on separate systems.
Koinly has not specified how many users may have been affected or when the breach occurred. The company said it is investigating the incident and working with Mixpanel to determine the full scope of the exposure.
