A PDF version of this rationale is also made available.
"Withdraw 540,750 ada for Oura by TxPipe: Maintaining Cardano’s Event Pipeline" (gov_action1k02...64d667) is a Treasury Withdrawals Governance Action and is therefore governed by both the general proposal standards in Article II, Section 6 and the additional Treasury Withdrawal standards in Article II, Section 7 of the Cardano Constitution. The Action seeks to withdraw 540,750 ada from the Cardano Treasury to fund a part-time maintainer for Oura, TxPipe's Cardano event pipeline, over twelve months at an annual rate of 105,000 USD. The vendor is TxPipe, the open-source studio that develops and maintains Oura, which was previously funded twice through Project Catalyst for feature development. The Action was submitted by Intersect on behalf of the vendor, with Intersect serving as administrator under its 2026 Treasury Reserve Smart Contract framework. The underlying proposal was socialized and approved off-chain through the Cardano Budget Process led by Intersect before being submitted on-chain.
Article II.6's procedural standards are satisfied. The action anchors to an IPFS-hosted document with the on-chain blake2b-256 hash 61d9b3fc86cca0f4a4e388ada992d8d90caf7168ee7c9fe661fae414f547e844, a content-addressed form that is immutable once posted, and the metadata supplies the title, abstract, motivation, rationale, budget summary, and supporting references that Article II.6.2 requires. Article II.7.1's terms-of-withdrawal requirement is met by the proposal's specification of purpose, a twelve-month delivery period, itemized costs (525,000 ada for Oura maintenance and enhancement plus a 15,750 ada Intersect budget administration fee), and the disbursement and return mechanics of the Treasury Reserve Smart Contract framework, under which funds are released against milestones outlined in the metadata and undisbursed funds can be returned to the Cardano Treasury through the framework's Sweep action. Article II.7.2's disclosure requirement is satisfied: TxPipe discloses funding through 30 Project Catalyst proposals across Funds 9 through 14, of which 26 have been delivered and 4 remain in progress and on schedule. Article II.7.3 is satisfied because the 540,750 ada requested here is well within the 350,000,000 ada Net Change Limit in force for the period spanning epochs 613 through 713, on its own and in aggregate with the other withdrawals pending at the time of submission.
Articles II.7.4, II.7.5, and II.7.6 are satisfied through the Intersect-administered Treasury Reserve Smart Contract pattern previously found constitutional by this Committee. Under Article II.7.5, the proposal designates Intersect as administrator, an entity other than the recipient vendor. Intersect operates the 2026 instance of the Sundae-Labs-developed TRSC framework, which mirrors the contracts used in the 2025 budget cycle, with a Project-Specific Smart Contract for this withdrawal. An Oversight Committee of six external, independent third-party entities provides the checks against unilateral administrative control, with explicit multi-signature authorization rules for each TRSC action type, including Fund, Disburse, Pause and Resume, Sweep, and Reorganize. A written off-chain Legal Contract governs delivery, and funds move to the Project-Specific Smart Contract only once that contract is prepared, with all milestones outlined within the metadata. Under Article II.7.4, audit and oversight costs are included within the overhead applied to the proposal, the Intersect administration fee covers administrative oversight, independent oversight is provided through Intersect and a technically capable third party with reporting obligations and milestone-based disbursement controls, and a public dashboard allows the community to audit TRSC and PSSC activity on-chain. Under Article II.7.6, the on-chain withdrawal destination is stake1784sdxt6jjennmstphgdu7l7c2scf5d02a6cve2dgn5s2kq5u3j9v, which is a script-locked stake address (CIP-19 mainnet header byte 0xf1), is not delegated to any stake pool, and is delegated to the predefined always-abstain DRep, each of which we verified on-chain at the time of this review.
Ace Alliance finds the proposed "Withdraw 540,750 ada for Oura by TxPipe: Maintaining Cardano’s Event Pipeline" Treasury Withdrawals Governance Action constitutional.
- Cardano Curia84feba94…6bd5YesExpired · term ends epoch 653Rationale
Cardano Curia finds the Treasury Withdrawal for Oura by TxPipe: Maintaining Cardano's Event Pipeline constitutional.
What is being proposed
This Treasury Withdrawal funds continued maintenance of Oura, TxPipe's Cardano event-pipeline software. The requested amount is 540,750 ada.
Constitutional assessment
Cardano Curia reviewed this action as a Treasury Withdrawal under the Constitution's governance-action standards and treasury-withdrawal requirements. The relevant requirements include a clear purpose and delivery period, disclosure of costs and refund circumstances, prior-funding disclosure, compliance with the applicable Net Change Limit, funded independent audit and oversight, designated administrators, and segregated auditable accounts delegated to the predefined abstain option while held before disbursement.
Maintaining open-source chain-event infrastructure supports downstream builders and operators. The bounded maintenance scope and controlled project-specific disbursement structure make the use of funds reviewable.
The action is also consistent with the constitutional tenets concerning fair treatment, reasonable use of blockchain resources, recognition of ecosystem contributions, preservation of value, and long-term sustainability, provided that the published administration, reporting, audit, milestone, and return-to-treasury commitments remain binding throughout execution.
Determination
Cardano Curia finds the action constitutional. This is a determination of constitutional compliance, not a guarantee of delivery performance or financial return.
Cardano Curia finds governance action b3d452bff7769d...0ccf#7 constitutional and records five internal votes for constitutional, with no votes for unconstitutional or abstain.

We consider this governance action to be constitutional.
This proposal is a Treasury Withdrawal Governance Action to withdraw ₳540,750 from the Cardano Treasury in connection with "Oura by TxPipe: Maintaining Cardano's Event Pipeline," proposed by TxPipe. This proposal met the 67% support threshold required during the Hydra voting phase of the 2026 Intersect budget process and has proceeded to the submission of an on-chain Treasury Withdrawal Governance Action in accordance with the approved budget process framework. This proposal refers to the proposal document on IPFS and presents the proposal's title, summary, rationale, justification, and relevant supporting materials. These correspond to the requirements of Article 2, Section 6, Paragraphs 1 and 2 of the Cardano Constitution. Regarding Article 2, Section 7, Paragraph 1, this proposal aims to maintain and enhance Oura, and the supporting materials specify an implementation period of 12 months. It also provides a breakdown of costs: ₳420,000 for blockchain developer fees, ₳105,000 for contingencies, and ₳15,750 for Intersect's budget management fees. Furthermore, the supplementary materials state that upon project completion, any ADA exceeding the amount necessary to cover the $105,000 project budget will be returned to the Cardano Treasury. Regarding Article 2, Section 7, Paragraph 2, the proposal discloses that TxPipe received funding through 30 Project Catalyst proposals from Fund 9 to Fund 14, and that it received open-source maintenance funding for Pallas, Dolos, and UTxO RPC through Intersect's 2025 budget cycle. Regarding Article 2, Section 7, Paragraph 3, the proposal confirms that the requested amount of ₳540,750 falls within the ₳350,000,000 Net Change Limit covering Epochs 613 through 713. Regarding Article 2, Section 7, Paragraph 4, this proposal includes audit and oversight costs as indirect expenses, and the Intersect budget management fee covers administrative oversight. Additionally, the supplementary materials state that, in addition to milestone-based disbursements and Delivery Assurance oversight, Blink Labs will serve as an independent reviewer to verify milestone completion and deliverable quality. Furthermore, it states that metrics related to ADA withdrawn via the dashboard can be tracked. Regarding Article 2, Section 7, Paragraph 5, the proposal designates Intersect as the administrator and outlines a framework for milestone-based disbursements and Delivery Assurance oversight. Regarding Article 2, Section 7, Paragraph 6, the proposal outlines a mechanism whereby, upon enactment of this governance action, funds are directed to the Treasury Reserve Smart Contract (TRSC) stake address, withdrawn from there to a UTxO remaining at the TRSC payment address, and then transferred to the Project-Specific Smart Contract (PSSC) using a Fund action once the legal contract is prepared and the vendor is ready. Furthermore, it states that the community can audit both smart contracts via a dashboard, and that this audit is immutably verifiable on-chain. Additionally, it is stated that these smart contracts will not be delegated to an SPO but will be delegated to a predefined, automatically abstaining DRep. Therefore, as no clear conflict with the Cardano Constitution has been identified, this proposal is deemed constitutional.
For the reasons stated above, we determine that it is constitutional.

Ok
A PDF version of this rationale is also made available.
The proposal funds the continued maintenance and evolution of Oura, an open-source event processing pipeline that enables developers and infrastructure operators to efficiently consume and route Cardano blockchain events. It therefore presents a reasonable case for advancing the long-term sustainability of Cardano under Article I - Section 1.
The proposal identifies an administrator, discloses previous Catalyst funding, specifies audit and oversight arrangements, defines custody through dedicated treasury management smart contracts, provides transparent on-chain administration, and states compliance with the applicable Net Change Limit.
Hence, I do not identify a clear constitutional violation and consider the proposal constitutionally compliant.

Tingvard judges the “Oura by TxPipe: Maintaining Cardano’s Event Pipeline” Treasury Withdrawal governance action constitutional.
This governance action requests 540,750 ADA from the Cardano Treasury to fund 12 months of maintenance and enhancement for Oura by TxPipe.
The proposal identifies the purpose of the withdrawal, the amount requested, the delivery period, and the intended scope of work. It states that the funding will support essential maintenance, dependency updates, Cardano protocol compatibility, performance improvements, bug fixing, documentation, community support, external contribution review, and AI-friendly documentation and integration resources.
The proposal discloses prior treasury and ecosystem funding received by TxPipe, including Project Catalyst funding and open-source maintenance funding through Intersect’s 2025 budget cycle.
The proposal states that the requested amount does not, at the time of submission, breach the applicable 350M Net Change Limit covering epochs 613 to 713.
The proposal identifies Intersect as administrator and states that treasury funds will be managed through the 2026 Treasury Reserve Smart Contract and a Project-Specific Smart Contract.
The proposal includes an oversight structure. Intersect will administer the TRSC and PSSC, while an Oversight Committee consisting of Sundae Labs, Cardano Foundation, Dquadrant, NMKR, Sundial, and Eternl will provide checks and balances on certain administrative actions.
The proposal addresses custody and delegation. It states that the TRSC and PSSC cannot be staked with an SPO and are delegated to the auto-abstain predefined DRep.
The proposal includes audit and oversight provisions. It states that audit and oversight costs are included in the proposal overhead, that independent oversight will be provided through Intersect and a technically capable third party, and that reporting obligations and milestone-based disbursement controls will apply.
The proposal also states that a public dashboard is available for the community to audit the TRSC or PSSC and track metrics related to the withdrawn ada.
Tingvard therefore finds that the proposal satisfies the relevant requirements for a Treasury Withdrawal governance action.
