A PDF version of this rationale is also made available.
"Withdraw 1,162,746 ada for MLabs Core Tool Maintenance & Enhancement: Plutarc..." (gov_action1k02...fsvefn) 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 1,162,746 ada from the Cardano Treasury to fund maintenance and enhancement of Plutarch and Ply, MLabs' core smart-contract tooling relied on by at least 26 teams building on Cardano, under a quarterly maintenance model with a clear priority hierarchy. The vendor is MLabs. 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 7ef041d793612ddcf163127fcdb33d4188330f77fa283bda449481a47314e3f6, 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 quarterly maintenance model across the funding period, itemized costs (1,128,880 ada for Plutarch and Ply maintenance, compatibility, and developer experience plus a 33,866 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: MLabs discloses prior Plutarch and Ply funding through Project Catalyst Funds 9 and 13, a prior 70,000 ada receipt from Intersect, and its prior treasury governance actions with their on-chain identifiers. Article II.7.3 is satisfied because the 1,162,746 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.

- Cardano Curia84feba94…6bd5YesActive · term ends epoch 799Rationale
Cardano Curia finds the Treasury Withdrawal for MLabs Core Tool Maintenance & Enhancement: Plutarch and Ply constitutional.
What is being proposed
This Treasury Withdrawal funds maintenance and enhancement of the Plutarch and Ply smart-contract development tools. The requested amount is 1,162,746 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.
The tools support Cardano smart-contract construction and typed on-chain/off-chain interfaces. The proposal describes a twelve-month maintenance need and a substantial existing ecosystem user base.
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#6 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 ₳1,162,746 from the Cardano Treasury in connection with "MLabs Core Tool Maintenance & Enhancement: Plutarch and Ply," proposed by MLabs LTD. 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 elements comply with 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 Plutarch and Ply, and the supplementary materials specify a 12-month implementation period. It also presents a breakdown of costs: ₳1,111,100 for software development, ₳17,780 for milestone audits, and ₳33,866 for Intersect budget management fees. Furthermore, the supplementary materials state that if there is a significant unused or surplus balance remaining after accounting for the costs of performing the approved work, completion, and reasonable exchange rate risk, it will be returned to the Cardano Treasury upon project completion. Regarding Article 2, Section 7, Paragraph 2, this proposal discloses past Treasury funding related to MLabs and also details past funding provided through Project Catalyst and Intersect. Regarding Article 2, Section 7, Paragraph 3, it confirms that the requested amount of ₳1,162,746 falls within the ₳350,000,000 Net Change Limit covering Epochs 613 through 713. Regarding Article 2, Section 7, Paragraph 4, the supplementary materials state that NoWitnessLabs will conduct an independent audit upon completion of each milestone deliverable and verify compliance with acceptance criteria prior to milestone payments. Additionally, a total of ₳17,780 is budgeted for the four milestone audit fees. Furthermore, this proposal outlines a governance framework that includes reporting obligations and milestone-based payment management. Regarding Article 2, Section 7, Paragraph 5, Intersect is designated as the administrator. Furthermore, a management framework that includes the management of milestone-based payments is presented. Regarding Article 2, Section 7, Paragraph 6, this proposal describes 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 the UTxOs 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, the proposal states that the community can audit the TRSC and PSSC through the dashboard and track metrics related to the withdrawn ADA, all of which are verifiable immutably on-chain. Additionally, it specifies that the TRSC and PSSC cannot be staked with an SPO and are delegated to the predefined auto-abstain 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
The proposal funds the continued maintenance of open-source smart-contract development tools used to compile, serialize and maintain Cardano on-chain applications. Maintaining their compatibility with ledger and Plutus evolution supports existing builders and applications and 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 Treasury, Catalyst and Intersect funding, specifies audit and oversight arrangements, defines custody through dedicated treasury management smart contracts, provides milestone-based disbursement controls, and remains in compliance with the applicable Net Change Limit. The requested withdrawal amount is also consistent with the stated budget total.
The metadata contains an unexplained inconsistency regarding adoption: the motivation refers to at least 26 teams using Plutarch and Ply, while the rationale refers to at least 15 teams. Although this discrepancy does not appear material to the proposal’s constitutional eligibility or intentionally misleading, greater consistency would have been preferable under the requirement for comprehensible governance metadata in Article II - Section 6.2.
Despite this quirk, I do not identify a clear constitution violation.

Tingvard judges the “MLabs Core Tool Maintenance & Enhancement: Plutarch and Ply” Treasury Withdrawal governance action constitutional.
This governance action requests 1,162,746 ADA from the Cardano Treasury to fund maintenance and enhancement of Plutarch and Ply.
The proposal identifies the purpose of the withdrawal, the amount requested, and the intended scope of work. It states that the funding will support ongoing maintenance, protocol-era and hard-fork compatibility, bug fixes, correctness improvements, optimizations, documentation, examples, technical writing, and developer-experience improvements.
The proposal discloses prior treasury and ecosystem funding received by MLabs, including prior funding for Plutarch, Cardano.nix, GrumpleStiltSkin, Project Catalyst funding, and prior Intersect funding for Conway-era Plutarch work.
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.
Tingvard finds the “MLabs Core Tool Maintenance & Enhancement: Plutarch and Ply” Treasury Withdrawal governance action constitutional.
- Eastern Cardano Council2ea7a78e…10ecNoActive · term ends epoch 726Rationale
We have determined that this treasury withdrawal governance action is unconstitutional.
The governance action with ID “gov_action1k02...fsvefn” and title “Withdraw 1,162,746 ada for MLabs Core Tool Maintenance & Enhancement: Plutarc...” is a Treasury Withdrawal, so is subject to ARTICLE II, Section 7 of the Cardano Constitution. While most of the requirements under this section were met by this governance action, it did not fulfil all the requirements under ARTICLE II, Section 7(1).
ARTICLE II, Section 7(1) states ""Treasury Withdrawals" actions must specify the terms of the withdrawal. This shall include: the purpose of the withdrawal, the period for delivery of proposed activities which the withdrawal shall be used for, the relevant costs and expenses of the proposed activities, circumstances under which the withdrawal might be refunded to the Cardano Treasury."
The governance action does not specify "the period for delivery of proposed activities which the withdrawal shall be used for" or "circumstances under which the withdrawal might be refunded to the Cardano Treasury."
We therefore find this governance action Unconstitutional.
This governance action does not sufficiently fulfil the criteria specified for treasury withdrawals in the Cardano Constitution, so is deemed unconstitutional.
