Following Base's network upgrade implementing Flashblocks (achieving 200ms partial block updates), some gate monitors are experiencing processing delays on Base Network, resulting in degraded functionality.
Next update at 01:00 UTC on Friday, November 6th.
We are continue to work on increased response times on the KYT API endpoint for registering withdrawal attempts. Clients with short timeouts may see timeouts or no response.
Retrieving withdrawal attempts and their alerts is not affected.

Reactor users should be aware of a new, secure login experience.
If you’re connecting from outside an approved network, you’ll now be able to sign in using email verification. Users will see two login prompts with this experience (once to pass the network gate, and again to log into Chainalysis products). We hope that this makes access to Reactor easier while continuing to ensure the highest level of protection for your information. See this document for more information: https://developers.chainalysis.com/resources/docs/reactor-email-verification/overview
