Koinly Reports Possible Email Address Leak from Third-Party Provider Breach

Koinly confirms a Mixpanel-related incident may have exposed user emails but stresses all sensitive financial data remains secure.

Fact Check
The statement is strongly supported by a consensus across all relevant primary sources. Multiple independent news outlets with moderate to high authority, including Crypto Briefing, ValueTheMarkets, and Bitget, all consistently report that the crypto tax software company Koinly announced a potential data leak. These sources unanimously specify that the leak was limited to user email addresses and was caused by a security breach at a third-party service provider. Some sources even identify the third party as the analytics service Mixpanel, adding a layer of specific, corroborating detail. While the highest-authority sources provided (from Koinly's own website) were not relevant to this specific incident, they do not contradict the information. The complete absence of conflicting evidence among the relevant sources and the consistency of the reporting make it highly probable that the statement is true.
