- Cardano’s V11 “van Rossem” hardfork is approaching mainnet after preview and preprod testnets completed the upgrade process.
- SPO readiness has accelerated, with 87% of the last 100 blocks and 83.65% of the past day produced on V11.
- Exchange readiness remains mixed, with 33 platforms completed or in progress and 25 not started, while mainnet governance approval remains pending before activation, raising coordination stakes for $ADA users across major services today.
Cardano’s V11 “van Rossem” upgrade is moving closer to mainnet activation, with readiness accelerating across stake pool operators, exchanges and governance channels. Preview and preprod testnets have already completed the hardfork, giving developers and operators a live rehearsal before the change reaches the main network. The process still feels delicate because Cardano upgrades depend on many actors moving in sync. For now, Cardano’s upgrade is entering its coordination phase, where technical validation is largely done, but mainnet activation still requires enough operational readiness and formal governance confirmation.
Readiness for the mainnet Cardano “van Rossem” V11 hardfork keeps growing.
✅ Preview and preprod testnets have already undergone the hardfork
✅ Mainnet SPOs are upgrading, multiple exchanges are ready, more in progress
✅ Governance action for the mainnet hardfork is live… https://t.co/eZkJRofkGa pic.twitter.com/2UpvRvRGE5

Stake pool operators are leading the visible readiness push. Recent data showed 87% block production on V11 across the last 100 blocks, while production over the past day reached 83.65%. That daily figure is well above the 67.99% measured across the past 30 days, showing that upgrade adoption has quickened. SPO readiness matters because these operators support block production and network stability during protocol changes. In practical terms, Cardano’s block producers are moving toward V11 alignment, reducing the risk of uneven support when the hardfork advances.
Exchanges Race to Match Operator Readiness
Exchange preparation is the other pressure point. Latest readiness figures showed 33 exchanges either completed their upgrade work or already in progress, while another 25 had not started. That gap matters for users because exchanges must maintain deposits, withdrawals and wallet services during protocol changes. A hardfork can be technically sound and still create friction if trading platforms lag behind. That makes exchange coordination the remaining operational bottleneck, especially as the network moves closer to the point where operator readiness, platform upgrades and governance can align safely.
The governance layer is also active. A mainnet hardfork governance action is now live on-chain, with final results still pending even as support continues to build. That structure reflects Cardano’s increasingly formal upgrade process: testnets validate the code, SPOs signal operational readiness, exchanges prepare user-facing systems and governance participants decide whether mainnet activation should proceed. The open question is not whether momentum exists, but whether every required layer converges without disruption. For now, V11 readiness is rising but not complete, leaving Cardano near the mainnet threshold while exchanges and governance outcomes determine the final path without avoidable service issues for $ADA users across trading venues, wallets and operational teams during final mainnet activation itself.
