The Cardano van Rossem hard fork has successfully landed on the preview test network on May 5, with Intersect confirming both the governance action submission and the release of Cardano Node version 11.0.1 Pre-Release. According to reports from Intersect, this upgrade moves Protocol Version 11 one step closer to mainnet, with the critical variable now shifting entirely to SPO (Stake Pool Operator) readiness. The release represents the first formal support for Cardano's intra-era hard fork mechanism, meaning the chain upgrades protocol version without triggering an era transition out of Conway. As part of the upgrade, the Cardano mainnet protocol will be upgraded to Major Version 11 and Minor Version 0, with the ledger remaining in the Conway era to prevent an era transition.
The upgrade introduces a constitutional requirement that at least 85% of stake pools by active stake must upgrade before ratification can proceed. As reported by Intersect, this threshold is embedded in Cardano's governance framework through the Voltaire era's on-chain governance model, where DReps and the Constitutional Committee must also vote before the action is enacted on-chain. The threshold logic exists to prevent chain split risks, as failure to achieve critical mass of block-producing nodes could result in incompatible blocks at the fork boundary, similar to the mainnet chain partition incident in late 2025. Protocol Version 11 bundles a focused set of improvements to Plutus performance, ledger consistency, and node-level security into a single intra-era upgrade, with transaction shape remaining unchanged and ecosystem upgrade effort minimized.
The upgrade bundles five new Plutus primitive sets defined in CIP-0109, CIP-0132, CIP-0133, CIP-0138, and CIP-0153, and unifies built-in functions across Plutus V1, V2, and V3. According to the release details, existing V1 and V2 scripts gain access to the full expanded built-in set after the fork, expanding DApp capabilities without requiring contract rewrites. The release also advances the experimental hard fork target to protocol version 12, signaling development pipeline progression beyond the current upgrade. The full set of built-ins (including those introduced) will become available across all Plutus language versions following the hard fork, expanding the capabilities of existing Plutus V1 and V2 scripts.
The market has responded positively to the hard fork progress, with ADA jumping 5% in a single session following the preview network submission. According to CoinMarketCap, ADA trades near $0.26 with resistance at $0.267, and a clean break above that level opens a path to $0.30. Analysts project ADA between $0.26 and $0.47 for 2026, with Changelly forecasting $0.42 by December 2026. However, the latest market analysis suggests that ADA still sits 92% below its all-time high of $3.10, indicating that while the hard fork progress is positive, the price recovery remains limited compared to the token's historical performance. The hard fork gives the Cardano price prediction a fresh set of numbers, with CME Group having launched ADA futures in early 2026 and a spot Cardano ETF remaining in play, which could bring institutional money into a token that has been starving for capital.
