Recovery Update

Validator rehearsal planned for tomorrow

We are preparing a coordinated recovery rehearsal on Devnet tomorrow, Tuesday, Sep 22, 2026, tentatively at 12:00 UTC, and invite validators to participate.

The protocol fix is prepared, and the simplified recovery procedure has completed a successful first internal trial. We will repeat the trial internally tomorrow morning with a wider transition window. Subject to successful validation, we plan to proceed to public Testnet, followed by the Devnet rehearsal.

To prepare for the rehearsal:
- If you already operate Devnet nodes, please ensure they are synced.
- If you would like to participate but do not currently run Devnet nodes, you can start a Devnet observer or squad using start-in-epoch mode and allow it to sync ahead of tomorrow’s rehearsal.

We will provide the rehearsal release, including the new binary and configuration, for installation through the usual upgrade process. The start time and operational instructions will be confirmed in this channel before the rehearsal.

If testing and the rehearsal are successful, we plan to proceed to the coordinated Mainnet rollout. Its timing will be confirmed separately with validators, exchanges and infrastructure partners.

Mainnet nodes must remain stopped until explicit restart instructions are issued. The preparation above applies only to Devnet.

Thank you for your support, it means the world to us. We keep building.
