Between 08:12 and 08:24 UTC on 2026-10-29, Candide's API was intermittently unavailable or slow due to DDoS attack. Requests to bundler and paymaster endpoints may have failed or timed out during this window.

The attack was mitigated within 12 minutes and all services have been operating normally since 08:24 UTC. We are reviewing our defenses to reduce the impact of similar attacks in the future.
