We identified a bug in the Zebra 2.4.0 release (which was cut 2025-07-11, but not officially announced yet) that corrupts the address index. It does not impact consensus, but causes some RPC calls to return invalid data. We have removed the release.
If you haven’t upgraded yet, please wait for the 2.4.1 release. If you have upgraded and need the RPC data and can’t wait for the next release, you will need to restore a v26 database backup and revert to 2.3.0, or revert to 2.3.0 and sync from scratch.
We are very sorry for the inconvenience and will provide more details in the future.
