Cardano activated the Van Rossem hard fork on July 18, 2026, moving the network to Protocol Version 11, as the hard fork reached Mainnet after months of testing, coordination, and governance discussions among developers, infrastructure providers, DReps, SPOs, founding entities, and the wider community.
It is a governance milestone within Cardano’s Voltaire era on-chain decision framework. Whether there is a price reaction after activation depends on broader market conditions as well as event-specific flows.
This news dropped as ADA surged nearly +10% overnight, making it one of the top-performing major cap tokens in recent days. It has a daily trading volume of $466M, a +12% uptick from yesterday.

Three Bodies Voted, All Said Yes
The Van Rossem hard fork initiation action was ratified on July 13, 2026, by all three governance bodies Cardano’s constitution requires. DReps, Delegated Representatives, the community-elected delegates who vote on behalf of ADA holders, approved the upgrade at 77.63% against a 60% constitutional threshold, according to the official Intersect MBO announcement.
SPOs (Stake Pool Operators – the companies and individuals running Cardano’s block-producing nodes) cleared the 51% minimum at 52.7%, a razor-thin margin that drew attention inside the community. The Constitutional Committee, a seven-member oversight body, voted 6-0-0-1: six in favor, zero against, zero abstentions, one absent.
For context on how Cardano arrived here: Van Rossem represents a governance-led milestone within Cardano’s Voltaire-era on-chain decision framework. The technical work remains essential, but the decision to proceed ultimately rests with the community’s governance bodies.
What the Cardano Protocol Version 11 Actually Changes
The headline technical goal is updating the Plutus Cost Model, Cardano’s smart contract cost model that underpins how smart contract execution is priced on-chain.
The update includes increases in the cost model of some existing primitives (effective immediately after enactment) and is preferred before the hard fork to provide settings for new primitives enabled by the fork itself.
The Intersect source also notes that the protocol includes ledger-related consistency improvements and updated reference input rules, marking a huge step for Cardano’s future.

Van Rossem as a Stepping Stone to Ouroboros Leios
The upgrade is part of the broader path toward Ouroboros Leios, Cardano’s planned transaction processing overhaul.
Meanwhile, broader market narratives around whale positioning and technical indicators may influence how investors interpret post-upgrade conditions.
Whether ADA reprices materially depends on what comes next: Leios testnet metrics, DeFi adoption driven by changing Plutus economics, and whether the community’s on-chain governance system, now battle-tested with a live mainnet upgrade, can continue executing without its founding company in the room.

Cardano (ADA) Price Analysis: Can $0.18 Resistance Break as Bullish Price Action Continues?
$ADA Cardano is finally trying to plant its feet after tagging the next downside target. A corrective wave 4 bounce is on the table, with room toward the $0.23 area if buyers actually show up.

Cardano is trading around $0.17-$0.176, up +9% over the past 24 hours, making it one of the top performers in the market today. This move comes from a July low near $0.14-$0.15 after clearing multi-year lows earlier in the month.
The recent bounce coincides with the network’s Van Rossem hard fork, activated on July 18, which upgraded Cardano to Protocol Version 11 with faster, cheaper smart contracts and stronger node security, a milestone traders hope will translate into sustained buying interest rather than a “sell the news” event.
Technically, ADA is trading above its 20-, 50-, 100-, and 200-day moving averages, with RSI above 60 and a positive MACD, suggesting constructive short-term momentum. Near-term targets sit in the $0.188-$0.195 range if resistance breaks.
That said, longer-term fundamentals remain mixed: staking participation is among the highest in crypto, but DeFi activity, user growth, and fresh capital inflows have lagged, capping upside versus ADA’s past highs near $3.
