Cardano's Van Rossem hard fork to activate at 21:44 UTC on July 18

Cardano (ADA) is scheduled to activate its Van Rossem intra-era hard fork on July 18, 2026 at 21:44:51 UTC, triggering automatically at slot height 192,844,800 at the next epoch boundary. The community has organized a public countdown call to follow the event live as the network moves toward Protocol Version 11. Governance cleared the upgrade earlier this month. The Van Rossem governance action reached the required ratification thresholds across all voting groups on July 13 and was formally ratified at the epoch boundary of Epoch 643. Under Cardano's on-chain governance rules, the ledger prioritized the hard fork over any other pending actions that might have ratified at the same time. No other proposals were delayed, expired, or affected. Developers frame Van Rossem as a foundational engineering release. The upgrade improves Plutus performance and updates the Plutus Cost Model that sets computation pricing for smart-contract operations. It also tightens ledger consistency and strengthens node security with enhanced primitives, VRF key uniqueness, and revised reference-input rules. VRF (verifiable random function) is used to select block producers, and enforcing key uniqueness is intended to reduce edge-case risks in leader selection. The hard fork is positioned as groundwork for the next major step: the Dijkstra-era hard fork, which is expected to introduce Ouroboros Leios. Leios is a redesigned consensus approach aimed at sharply increasing throughput by separating block production from transaction validation so the network can process more data in parallel. Shipping enabling primitives now is meant to reduce the engineering burden when Dijkstra eventually activates. Testnet work on Leios continues. Engineers released two new prototype builds, prototype2026w27a and prototype2026w28, after addressing bugs found during live testnet runs. A dedicated voting dashboard has also been deployed to improve observability, showing how endorser blocks are proposed, voted on, and certified. Separately, the Cardano Foundation joined x402 as an Associate Member under the Linux Foundation. x402 is an open payments standard built around reviving the HTTP 402 status code, enabling applications and autonomous AI agents to pay per request in stablecoins without accounts, API keys, or checkout flows. The standard targets machine-to-machine commerce and agent-driven micropayments. On the market side, COINOTAG's "42-indicator" composite model rates resistance at $0.1669 at 78/100 (strong), citing a bearish support-to-resistance flip and the Ichimoku Kijun line. Support at $0.1578 scores 71/100, based on Supertrend and high-volume node clustering. With spot near $0.166, ADA is trading between those levels. Derivatives data shows a slightly positive funding rate of 0.0031%, open interest around $159 million, and a long/short account ratio of 2.57 (72% long), pointing to crowded bullish positioning that could unwind quickly. A Fear & Greed reading of 25 indicates extreme fear amid a broader downtrend. A daily close above $0.1669 would open the $0.1836 area; a break below $0.1578 would invalidate the bullish setup.
