mainnet.base.org public RPC changes: October 8th, 2026
Completed - The scheduled maintenance has been completed.
Oct 8, 19:42 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Oct 8, 12:00 UTC
Scheduled - Starting Oct 8, 2026, mainnet.base.org will no longer serve the debug, trace, and txpool namespaces, and read requests will be subject to a lower rate limit. The endpoint remains free and best-effort for basic reads.

Apps that use these namespaces or need higher throughput should move to a dedicated RPC provider before Oct 8. See our supported providers: https://docs.base.org/get-started/base-services-hub#service-providers.
