Enacted Cardano Treasury Withdrawal Proposals

This treasury withdrawal funds **A member-based organization for the Cardano ecosystem: Intersect** which will provide the following services: Intersect exists to serve as a neutral, nonprofit coordination layer that bridges decentralized governance and decentralized infrastructure. Our mission is not to direct the network, but to enable it. By stewarding core systems, supporting community-led processes, and facilitating safe, transparent delivery. Specifically, this proposal will fund Intersect to: - Steward core infrastructure - Execute the Administrator role - Support participation and coordination - Facilitate roadmap and budget processes - Expand ecosystem capacity Note: Intersect's original proposal submitted early in the off-chain process was updated after recent leadership changes. However, this proposal reflects the approved Budget Info Action and new strategic direction. This treasury withdrawal funds one of 39 proposals to give effect to the approved budget info action for ₳275,269,340, administered by Intersect via gov_action1u9x73kwufaxa70lfy59g4ynwyrcsaxdcd0gxzzmh67s9fxq4j8hqqk2phgh. The information provided herein is intended to fulfill the spirit of the constitutional requirement for a treasury withdrawal info action by also providing the details of the proposed solution, alignment to the budget, and amount to be withdrawn from the Cardano Treasury.

This treasury withdrawal funds **Cardano Builder DAO** which will provide the following services: The Cardano Builder DAO (**CB DAO**) is a **smart contract-enforced**, **member-governed funding mechanism** created to **support the application-layer growth of the Cardano ecosystem**. Its core purpose is to **provide sustainable financial backing** and **strategic oversight to high-impact projects** that are directly responsible for existing user adoption, on-chain activity, Total Value Locked (TVL), and ecosystem engagement. While Cardano's governance structure and funding mechanisms, such as Project Catalyst and core development committees, have been instrumental in bootstrapping protocol advancements and open-source tooling, **there remains a substantial gap in ongoing support for live, user-facing products/services. CB DAO fills that gap.** Through a **transparent governance framework**, **strict accountability mechanisms**, and a **metrics-first funding approach**, CB DAO ensures that builders with growing products on mainnet can scale sustainably, integrate cutting-edge Cardano infrastructure (e.g. Hydra, Leios, Midgard), and contribute to the ecosystem's long-term growth.

This treasury withdrawal funds **AdaStat.net Cardano blockchain explorer** which will provide the following services: We propose to continue development and support of the AdaStat.net Cardano blockchain explorer for the next 24 months. Planned work includes performance optimizations, improvements to UX/UI, and new features related to Cardano's evolving governance model and on-chain tooling. The frontend is developed using Vue.js and Tailwind CSS, which allows very small bundle size and fast loading time on different devices. The backend is built on Node.js and PostgreSQL, combining standard DB-Sync tables with custom-optimized indexes for high-speed data access. This dual approach enables advanced search and filtering across both on-chain and off-chain metadata --- including DRep names, stake pool tickers, token labels, and more. Infrastructure is horizontally scalable. Multiple backend servers work behind load balancer and handle traffic based on real-time utilization. This gives high availability and stable performance, even during peak usage. This Treasury Withdrawal is submitted by Intersect on behalf of the vendor.

This treasury withdrawal funds **ZK Bridge** which will provide the following services: Our proposal is building a ZK bridge for Cardano, which we will deploy on the Cardano testnet. As part of this initiative, we will define a communication protocol for the bridge, provide the full source code of the smart contracts on the Cardano side, and produce comprehensive technical documentation detailing the protocol between Cardano and any other isomorphic blockchain. We will provide a circuit that enables a relayer to generate the ZK proof that a locking transaction was successfully added to the chain, which can then be verified on the receiving blockchain. This way, any blockchain will be able to implement a ZK bridge with Cardano, leveraging its newly added capability to generate such proofs. This allows for a variety of uses, such as moving assets outside Cardano just by providing the proof that they've locked an equivalent amount in the Cardano Smart Contract. The resulting bridge can serve as a generic framework for interoperability between Cardano and any other blockchain willing to implement the corresponding counterpart contracts. Furthermore, we will implement contracts in Aiken to mint assets on a Cardano-like (isomorphic) blockchain and deploy them on the Cardano testnet, providing a fully functional proof of concept. These building blocks will enable developers to create bridges between Cardano and other chains with minimal additional effort.
