Cronos Data Delay
Resolved - This incident has been resolved. Please reach out to support@chainalysis.com if you have any questions or require further assistance.
Sep 3, 05:15 UTC
Identified - The Cronos network was halted on Sunday, August 30, following a DeFi-related attack and was subsequently rolled back to block 90896189.

Once the network resumed producing blocks, our systems began re-ingesting Cronos data. During this process, we identified additional data processing issues affecting Cronos data in KYT and Reactor. As a result, some Cronos data may appear outdated.

Our team is working to restore accurate and up-to-date data and will provide further updates as they become available.
