What's happening: We are performing a routine infrastructure optimization to improve the reliability and performance of the KYT API. A small number of low-traffic API endpoints will be migrated to our modernized infrastructure during this window.
Expected impact: No downtime is expected. The affected public endpoints include reference data lookups (/v2/networks, /v2/categories) and deposit address registration (/v1/users/{userId}/depositaddresses). Core transaction monitoring endpoints (transfers, withdrawal-attempts, alerts) are not affected.
What you need to do: No action is required. If you experience any issues during or shortly after the maintenance window, please contact our Support team (support@chainalysis.com).

Investigating -
We have received reports regarding degraded performance on Reactor. We are currently investigating, and we will share any details as they become available.
