Cardano has successfully activated the van Rossem hard fork. The upgrade reduces the cost of executing smart contracts. It prepares the network for the upcoming Ouroboros Leios scalability up
Cardano has officially activated the van Rossem hard fork, introducing improvements designed to make smart contracts more efficient and cost-effective. The latest network upgrade is expected to lower execution costs for developers and users while laying the technical foundation for future enhancements.
Reducing smart contract costs is a key step in improving the overall user experience on Cardano, especially as decentralized applications (dApps) continue to expand across the ecosystem.
The Cardano van Rossem hard fork focuses on optimizing how smart contracts operate on the blockchain. By lowering execution costs, developers can build and deploy decentralized applications more efficiently, while users may benefit from reduced transaction expenses when interacting with those applications.
The upgrade is part of Cardano’s ongoing effort to improve network performance without compromising security or decentralization. These incremental improvements are designed to support long-term ecosystem growth.

Beyond the immediate cost reductions, the van Rossem hard fork also serves as an important milestone ahead of the Ouroboros Leios scalability upgrade, which is expected later this year.
Ouroboros Leios aims to significantly increase Cardano’s transaction throughput while maintaining the network’s security and decentralization. If successfully implemented, the upgrade could strengthen Cardano’s position as a blockchain capable of supporting larger volumes of decentralized applications and users.
With the van Rossem hard fork now live, the Cardano ecosystem is taking another step toward improved efficiency and greater scalability, as developers and investors look ahead to the network’s next major upgrade.
