The Robonomics parachain on Kusama (para ID 2048) stopped producing blocks on September 28, 2026. The final block is **#12,268,835** (19:48 UTC), the last Robonomics head finalized by the Kusama relay chain (`Paras.Heads(2048)`).

Kusama hosted the Robonomics R&D stage since 2021. Production has moved to Polkadot, and this closes the Kusama chapter.

### How we stopped it

Our first attempt was a multisig call that removed `Session::QueuedKeys`. The session set did go empty at the next rotation, but Aura kept its authority list, so blocks kept coming. We then enacted a final runtime upgrade (spec version 49) through the team multisig. It took effect at block #12,268,835, which became the final one. The collators authored three more blocks on top of it (up to #12,268,838), but the relay chain never included them. Coretime on Kusama ran until September 22 and was not renewed.

The chain state at the final block stays as it is. A database archive of the parachain is available at `snapshots.robonomics.network/#kusama`.

### What happens to Kusama XRT

All XRT balances at the final block move to Polkadot with a **+20% bonus**. There is no buyback option on the Kusama side.

Why the difference from Ethereum: for XRT holders on Ethereum the move to Polkadot was a pivot — a lot changed for them, so they were offered a choice. For Kusama holders nothing changes except the step from R&D into production. The bonus is our thank-you for getting to production together. Details on where the balances show up will follow in a separate post.

Thanks to the Kusama community and to everyone who ran collators and built on Robonomics there.

Analyser les évolutions techniques des écosystèmes blockchain, comprendre la fermeture d’un parachain sur Kusama ou suivre les discussions de gouvernance au sein du réseau Polkadot demande des capacités de concentration considérables.
