Ace Alliance finds the proposed "Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026-2028" Treasury Withdrawals Governance Action constitutional. Rationales are archived at https://github.com/ace-alliance/ace-voting/
A PDF version of this rationale is also made available.
"Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026-2028" (gov_action14u2...qgeu8p) 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.
This TWGA seeks to withdraw ₳39,787,316 from the Cardano Treasury to fund Tweag's delivery of seventeen interdependent work packages across nine core Cardano infrastructure areas, including production-grade mainnet delivery of Peras v1 and Peras v2, History Expiry for sustainable node economics, a Hard Fork Mempool Bridger, conformance and mutation testing, adversarial fork testing, Canonical Ledger State and Mithril work, Plutus Script Re-Executor tooling, Hoarding Node deployment, block-cost investigation, and ongoing maintenance of the Genesis Sync Accelerator and Cardano Node Emulator. Delivery runs across 2026 through 2028. Funds are directed into Intersect's 2025 Treasury Reserve Smart Contract (stake17xzc8pt7fgf0lc0x7eq6z7z6puhsxmzktna7dluahrj6g6ghh5qjr), with subsequent migration to a 2026 TRSC once established, and the withdrawal is administered by Intersect on behalf of Cardano Development Holdings.
The procedural standards of Article II.6 are satisfied: the proposal anchors to an IPFS-hosted document with the on-chain blake2b-256 hash, a content-addressed form "immutable and incapable of being altered after submission," and the metadata provides the title, abstract, justification, and supporting materials required by II.6.2.
The substantive Article II.7 requirements are met as well. Under Article II.7.1, "Treasury Withdrawals actions must specify the terms of the withdrawal," and the proposal specifies the purpose (seventeen interdependent core Cardano infrastructure work packages), period (2026 through 2028), itemized costs (derived from an average market rate of $176/hour for senior Cardano infrastructure engineers at a conservative ADA/USD conversion of 0.25), and refund circumstances (end-of-period sweep and proportional return on cancelled or reduced deliverables). The disclosure requirement of Article II.7.2 is met by an aggregate disclosure of ₳11,070,322.68 allocated within the Treasury Smart Contract (ID 680d1b63565577986442d24e). The 350M Net Change Limit covering Epoch 613 to Epoch 713 is set, and this ₳39,787,316 ask does not exceed it, satisfying Article II.7.3 and Appendix I guardrail TREASURY-02a.
A 3rd Party Assurer funded as part of the withdrawal supports milestone acceptance, satisfying the periodic independent audit and oversight allocation under Article II.7.4. Article II.7.5 is satisfied by Intersect's designation as Administrator, acting on behalf of Cardano Development Holdings, operating through the TRSC and PSSC framework with milestone-based disbursement controls and a five-member external Oversight Committee (Sundae Labs, Cardano Foundation, Dquadrant, Xerberus, NMKR). The custody requirement of Article II.7.6 is satisfied by the proposal's commitment that TRSC and PSSC instances are non-staked with an SPO and delegated to the auto-abstain predefined DRep, with a community-audit dashboard, on the same Intersect TRSC pattern we have accepted as constitutional in prior actions in this family.
For these reasons, Ace Alliance finds the proposed "Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026-2028" Treasury Withdrawals Governance Action constitutional under Article II.6.1 and Article II.7.1 through II.7.6.
- Cardano Curia84feba94…6bd5YesActive · term ends epoch 799Rationale
Cardano Curia finds this governance action constitutionally acceptable and supportive of Cardano’s governance objectives, with an internal position of 4 YES / 1 ABSTAIN. The abstention reflects a preference for stronger immutability and verification signals in the referenced off-chain materials, not opposition to the proposal’s intent.
Vote and internal outcome
- Cardano Curia position: YES
- Internal tally: 4 YES / 1 ABSTAIN
Assessment basis
This rationale evaluates the action against constitutional expectations for governance integrity: clarity of scope, transparent participation, and durable auditability of supporting materials.
Why Cardano Curia supports (YES)
- Constitutional intent alignment: The action appears consistent with the Constitution’s aims of sustaining the network and enabling transparent, fair governance processes.
- Governance integrity: The proposal is treated as within the governance framework provided the on-chain references resolve to a single, canonical, immutable source of truth (URL + hash).
- Ecosystem benefit: The action’s apparent direction supports long-term sustainability and operational effectiveness for ecosystem participants.
- Accountability expectation: Support is given with an expectation of auditable documentation and, where applicable, measurable deliverables and reporting.
Why one member ABSTAINS
The abstention is a process-quality signal requesting stronger evidence that the canonical proposal text is immutable and unambiguous (single canonical document + hash) and that success criteria are verifiable where relevant.
Non-blocking improvement requests
- Ensure canonical documents are immutable (e.g., IPFS) and the governance metadata includes a stable URL + content hash.
- Where relevant, publish measurable deliverables, reporting cadence, and an audit trail sufficient for independent verification.
Cardano Curia records a YES position with internal support of 4 YES / 1 ABSTAIN. The action is treated as constitutionally acceptable, with an explicit request for strong immutability and auditability signals in the canonical referenced materials.

We consider this governance action to be constitutional.
This proposal is a Treasury Withdrawal Governance Action to withdraw ₳39,787,316 from the Cardano Treasury for the project “Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026–2028” by Tweag by Modus Create. Regarding Article 2, Section 6, Paragraphs 1 and 2 of the Cardano Constitution, this proposal adopts an immutable off-chain reference using IPFS. Furthermore, the proposal text includes the title, summary, rationale, justification, work package, budget, implementation period, management structure, audit and reporting structure, refund conditions, Net Change Limit compliance, and other details; we therefore determine that it presents information sufficient for evaluation as a Governance Action. Regarding Article 2, Section 7, Paragraphs 1 and 2, this proposal aims to improve and maintain the Cardano core infrastructure, including Peras, History Expiry, Hoarding Node, Plutus Script Re-Executor, Mutation Testing, and Conformance Testing. It details the implementation period (2026–2028), 17 work packages across 9 core infrastructure areas, budget breakdown, delivery strategy, and refund conditions. It also details the objectives and rationale regarding Peras’s mainnet deployment support, developer tooling, testing infrastructure, network monitoring, and other related matters. Furthermore, the proposal includes a history of past Treasury funding received. Regarding Article 2, Section 7, Paragraph 3, the proposal confirms that the requested amount is ₳39,787,316 and falls within the 350M ADA Net Change Limit applicable to Epochs 613–713 at the time of submission. Furthermore, the requested amount is stated in ADA, and the proposal also includes a USD equivalent based on an estimated ADA/USD conversion rate at the time of writing. Article 2, Section 7, Paragraphs 4 and 5 describe contract management with Intersect as the administrator, milestone management, third-party assurance, delivery assurance, the Treasury Reserve Smart Contract (TRSC) and Project-Specific Smart Contracts (PSSC), the Oversight Committee, auditing, reporting obligations, and auditability via a public dashboard. It also details the treasury management smart contract framework by Sundae Labs, as well as audits by TxPipe and MLabs. Furthermore, Article 2, Section 7, Paragraph 6 describes fund management using TRSC and PSSC, non-delegation to SPOs, and delegation to the auto-abstain predefined DRep. We determine that this structure is intended to align with the requirements of “auditable by the Cardano Community,” “separate accounts,” “not delegated to a SPO,” and “delegated to a predefined abstain voting option.” Therefore, as no clear conflict with the Cardano Constitution has been identified, we determine that this proposal is constitutional.
For the reasons stated above, we determine that it is constitutional.

We have determined that this treasury withdrawal governance action is constitutional.
The governance action with ID "gov_action14u2...qgeu8p" and title "Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026–2028" is a Treasury Withdrawal, and is therefore subject to the following sections and guardrails in the Cardano Constitution.
ARTICLE II, Section 6 of the Cardano Constitution states that governance actions must follow a standardized and legible format, including a URL hosting an immutable document and a corresponding hash, and must provide sufficient rationale including a title, abstract, justification, and supporting materials.
This governance action includes a valid URL and hash, which matches the hash of the off-chain documentation referenced. The rationale also meets the minimum content specified in this section.
ARTICLE II, Section 7 specifies that Treasury Withdrawal governance actions must include the following:
1. Purpose, Delivery Period, Costs, and Refund Conditions
This governance action specifies:
- The purpose of the withdrawal is “to fund Tweag by Modus Create's delivery of 17 work packages across 9 core infrastructure areas for the Cardano ecosystem over 2026–2028.”
- The period for delivery of proposed activities is “2-year duration (2026–2028)”
- The relevant costs and expenses are stated as "The total ask of ₳39,787,316 is based on an average market rate of $176/hour for senior Cardano infrastructure engineers."
- The circumstances under which funds may be refunded to the Cardano Treasury as “All funds not disbursed by the end of the delivery period will be returned to the Cardano Treasury. A final reconciliation will be published as part of the oversight reporting cycle. In the event of partial delivery or scope reduction, unspent funds associated with canceled or reduced deliverables will be returned proportionally.”
These elements fulfil the requirements of Article II, Section 7(1).
2. Prior Treasury Funding Disclosure
ARTICLE II, Section 7(2) requires disclosure of whether the prospective recipient has received ada from the Cardano Treasury within the last 24 months.
This governance action states that "TWEAG has been accountable for delivering work funded by the Cardano Treasury. The total funds allocated are ₳11,070,322.68 within the Treasury Smart Contract. ID: 680d1b63565577986442d24e.". This fulfils the requirement of ARTICLE II, Section 7(2).
3. Net Change Limit (NCL)
ARTICLE II, Section 7(3) requires that Treasury Withdrawals must not exceed the Net Change Limit.
The Net Change Limit in effect at the time of submission of this vote on-chain is the governance action with ID "gov_action1m3x...4jsr7q".
- A. Current NCL Amount: 350000000 ada
- B. Current NCL Time Period: Epoch 613 to Epoch 713 (Inclusive)
- C. Total of Treasury Withdrawals within the Current NCL Time Period: 199352090 ada
- D. Amount of this Treasury Withdrawal: 39787316 ada
- E. "C" plus "D" = 239139406 ada
- F. "A" minus "E" = 110860594 ada
As the value of "F" is greater than or equal to zero, this governance action fulfils the NCL requirement.
4. Audit Allocation and Oversight Metrics
ARTICLE II, Section 7(4) states "Treasury Withdrawals actions shall require an allocation of ada as a part of such funding request to cover the cost of periodic independent audits and the implementation of oversight metrics as to the use of such ada."
This governance action states that "Audit and oversight costs are included within the overhead applied to this proposal. The Intersect administration fee covers administrative oversight and is reflected within the cost of this proposal. Independent oversight will be provided through Intersect and technically capable third-party, including reporting obligations and milestone-based disbursement controls.", which fulfils the requirements of ARTICLE II, Section 7(4).
5. Designated Administrators
ARTICLE II, Section 7(5) requires that one or more administrators are designated to monitor fund usage and ensure deliverables are achieved.
This governance action states that "This proposal designates Intersect as the administrator, operating on behalf of the CDH, as detailed in the "Accountability" section.", which fulfils this requirement.
6. Fund Management Requirements
ARTICLE II, Section 7(6) states "Any ada received from a Cardano Blockchain treasury withdrawal, so long as such ada is being held by an administrator prior to further disbursement to the Treasury Withdrawal Recipient, must be kept in one or more separate accounts that can be audited by the Cardano Community, and such accounts shall not be delegated to an SPO but must be delegated to the predefined abstain voting option."
This governance action specifies the following withdrawal address, which at the time of assessment is not delegated to an SPO and is delegated to the auto abstain voting option:
- stake17xzc8pt7fgf0lc0x7eq6z7z6puhsxmzktna7dluahrj6g6ghh5qjr
Finally, the guardrails that require consideration for this governance action are TREASURY-01a, TREASURY-02a, and TREASURY-03a. These are addressed as follows:
- TREASURY-01a - The net change limit with governance action ID "gov_action1m3x...4jsr7q" is currently in effect, after being "agreed by the DReps via an on-chain governance action with a threshold of greater than 50% of the active voting stake".
- TREASURY-02a - As per the above assessment, this treasury withdrawal does not exceed the current Net Change Limit.
- TREASURY-03a - This treasury withdrawal is denominated in ada.
We therefore find this governance action Constitutional.
This governance action sufficiently fulfils the criteria specified for treasury withdrawals in the Cardano Constitution, so is deemed constitutional.
