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.

Recovery Update

Mainnet will remain paused today.

Recovery testing has taken longer than planned, but the current internal test run is nearing completion. Subject to successful results, we aim to begin the public Testnet recovery run within approximately the next hour.

If that completes successfully, we are targeting the Devnet rehearsal with validators around 17:30 UTC today. This remains tentative; we will confirm the start time and operational instructions in the validator channels.
Mainnet restart timing will be confirmed separately, following successful testing and rehearsal and coordination with validators, exchanges and infrastructure partners.

We know this wait is difficult. Thank you for your being here with us.

📣️️ TESTNET HARD-FORK Upgrade T2.1.1.0

We are upgrading the TESTNET!

Version T2.1.1.0 is out.

ℹ️ This release is a hardfork trial on the public testnet. The hardfork took place at round 29371591, corresponding to September 19, 2026, at 12:39 UTC. It also includes additional security hardening and improvements.

📅 No activation flags.

Recovery Update
The recovery hard fork has been completed successfully on public Testnet.

The Devnet rehearsal with validators is now planned for tomorrow, Wednesday, September 23, at approximately 08:00 UTC. Participating validators should prepare to be available from that time. The start and operational instructions will be confirmed in the validator channels.

Subject to a successful rehearsal, final checks and coordination with validators, exchanges and infrastructure partners, we are tentatively targeting the start of the Mainnet recovery rollout for 14:00 UTC tomorrow. This is not a confirmed restart time: validators will need time to synchronize before block production can resume.

Validators: please confirm your availability for 14:00–16:00 UTC tomorrow in the validator channels. Please keep Mainnet nodes stopped until explicit restart instructions are issued.

Mainnet remains paused. Please continue to wait for the all-clear: do not submit or rebroadcast transactions, or use EGLD and ESDT deposit and withdrawal routes through exchanges or bridges.

We know the continued wait and changes in timing have been difficult. Thank you for your patience, and to all of you for supporting the recovery.

Recovery Update

We are preparing a new release for the next recovery attempt. An epoch change occurred during today’s attempt, so we need to test recovery across that epoch change before proceeding.

We aim to have the release ready tomorrow morning, allowing a longer window for validators to upgrade, synchronize and bring their nodes online before activation.

You do not need to stay on standby tonight. We are tentatively targeting activation for approximately 16:30 UTC tomorrow, Thursday, September 24, subject to successful testing and validator readiness.
We will share the release, upgrade instructions and confirmed activation timing in this channel. Please keep your nodes stopped until further instructions.

Thank you for your availability, patience and support throughout a demanding day. We deeply appreciate the time and effort you are putting into the recovery.
