Ace Alliance finds the proposed "Scalus: Cardano’s Application Platform for Building, Launching, and Scaling" Treasury Withdrawal Governance Action Constitutional. Rationales are archived at https://github.com/ace-alliance/ace-voting/
The Scalus Treasury Withdrawal requests ₳8,503,000, inclusive of a 10% refundable contingency, from the Cardano Treasury to fund Lantr Engineering's twelve-month delivery of the Scalus application platform over the period July 2026 to June 2027. On enactment the action transfers the requested ada into a SundaeSwap treasury-contracts escrow, from which funds are released against milestones. Our review concerns only the constitutionality of the withdrawal under Article II Sections 6 and 7 and the Appendix I Treasury guardrails; it does not assess the technical design, commercial viability, or ecosystem merits of the platform. We note for transparency that one member of the proposal's independent oversight board is affiliated with IOG and that the proposing team's CTO is a former IOG engineer. We record the connection once and apply the same scrutiny we would apply to any other proposer.
Article II.6 (Governance Action Standards). The proposal is anchored to immutable, content-addressed IPFS storage (
ipfs://QmPuukXDGrY4VjeprLZhovQfWCY5RDyXjQAPUKhRFNPiDT) with the matching on-chain hashf5df943e70635c794b09a93e52e7ec9b80855edc5bfa31bf2d5a068377a5478e, satisfying the immutable-document and format requirements of Section 6.1. The metadata supplies a title, abstract, justification, milestone breakdown, budget, and supporting reference annexes, meeting the rationale-sufficiency requirement of Section 6.2.Article II.7.1 (Terms of the Withdrawal). The proposal specifies each required term: the purpose (development of the Scalus application platform across four milestones), the delivery period (July 2026 to June 2027), the relevant costs and expenses (an itemized budget separating development, product management, security and audits, documentation, and outreach, modeled on FTE effort at a stated reference rate), and the circumstances of refund (unspent contingency and any funds remaining after expiration sweep back to the Treasury automatically at the contract level).
Article II.7.2 (Prior Treasury Funding Disclosure). The proposal discloses prior community funding within the preceding 24 months, namely three Project Catalyst rounds and the 2025 Treasury Budget allocation, totaling ₳1,085,692 allocated with ₳888,384 received to date, and identifies the relevant project and governance action identifiers. The disclosure requirement is satisfied.
Article II.7.3 (Net Change Limit), TREASURY-01a, TREASURY-02a. A Net Change Limit of 350M ada for epochs 613 to 713 is in force. The ₳8,503,000 requested here sits well within that limit, and the proposal acknowledges it expressly. The limit is established and not relitigated here.
Article II.7.4 (Independent Audits and Oversight Metrics). The budget reserves a fixed allocation for audit and assurance: external security audits of the smart contract and node components, an independent financial audit with a published report targeted for Q3 2027, a security bounty program, and quarterly third-party technical assurance by No.Witness Labs, all funded from the request. This satisfies the requirement that the withdrawal allocate ada for periodic independent audits and oversight metrics.
Article II.7.5 (Administration). The proposal designates an independent, multi-party oversight board whose members hold no stake in Lantr Engineering. The board co-signs disbursements, reviews milestones, and can pause or halt funding if delivery falters, discharging the requirement to designate administrators responsible for monitoring use of funds and ensuring deliverables are achieved.
Article II.7.6 (Separate Auditable Account and Delegation Restrictions). Withdrawn funds are held in the independently audited SundaeSwap treasury-contracts escrow, with all disbursements, claims, sweeps, and reorganizations recorded in a public on-chain transaction journal that the community can audit. The contract enforces auto-abstain DRep delegation and prohibits SPO delegation for all escrowed funds, meeting the segregated-account and delegation requirements of Section 7.6.
Appendix I (Guardrails). The withdrawal is denominated in ada, satisfying TREASURY-03a, and operates within the Net Change Limit per TREASURY-01a and TREASURY-02a. The Parameter Update, Hard Fork Initiation, Update Committee, New Constitution, and No Confidence guardrail groups are not engaged by a Treasury Withdrawals action and require no analysis here.
Ace Alliance finds the proposed "Scalus: Cardano’s Application Platform for Building, Launching, and Scaling" Treasury Withdrawal Governance Action Constitutional.
- Cardano Japan Council725d4d44…7b31YesExpired · term ends epoch 653Rationale
We consider this governance action to be constitutional.
This proposal is a Treasury Withdrawal Governance Action to withdraw ₳8,503,000 from the Cardano Treasury for “Scalus: Cardano’s Application Platform for Building, Launching, and Scaling” by Lantr Engineering. Regarding Article 2, Section 6, Paragraphs 1 and 2 of the Cardano Constitution, this proposal adopts immutable off-chain references using IPFS. The proposal text includes an overview, rationale, implementation plan, milestones, budget, risk management, governance structure, and a Constitutionality Checklist, and we determine that it presents information sufficient for evaluation as a Governance Action. Regarding Article 2, Section 7, Paragraph 1, this proposal aims to develop, deploy, and scale the Scalus application platform. It details the 12-month implementation period from July 2026 to June 2027, the milestone structure, implementation plan, budget breakdown, contingency fund, and repayment conditions. Regarding Article 2, Section 7, Paragraph 2, this proposal constitutes the second Treasury Withdrawal within the past 24 months, and it is disclosed that the previous proposal was submitted in July 2025 and enacted in August 2025. Regarding Article 2, Section 7, Paragraph 3, the requested amount for this proposal is ₳8,503,000, which falls within the 350M ADA Net Change Limit applicable to Epochs 613–713 at the time of submission. Additionally, the requested amount for this proposal is stated in ADA. Regarding Article 2, Section 7, Paragraph 4, the proposal includes provisions for regular independent audits and quarterly reports, and states that the Budget section contains provisions regarding auditing and oversight. Regarding Article 2, Section 7, Paragraph 5, Lantr Engineering is designated as the administrator, and the proposal explains the structure for monitoring and accountability through milestone-based implementation, public reporting, and a transparent development process. Furthermore, regarding Article 2, Section 7, Paragraph 6, the proposal specifies that Treasury funds will be managed via segregated script accounts using the SundaeSwap treasury-contracts framework, that Treasury funds are not delegated to any SPO, and that delegation is set to the predefined abstain voting option. Therefore, as no clear conflict with the Cardano Constitution has been identified, we determine that it is constitutional.
For the reasons stated above, we determine that it is constitutional.
- Eastern Cardano Council2ea7a78e…10ecYesActive · term ends epoch 726Rationale
We have determined that this treasury withdrawal governance action is constitutional.
The governance action with ID "gov_action1uzg...pwp09a" and title "Scalus: Cardano’s Application Platform for Building, Launching, and Scaling" 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 as "funding the development of Scalus application platform for the 12 months period"
- The period for delivery of proposed activities as "July 2026 - June 2027"
- The relevant costs and expenses under the heading "Budget"
- The circumstances under which funds may be refunded to the Cardano Treasury as "Funds remaining in the contract after expiration sweep back to the Cardano Treasury automatically. Enforced at the contract level; cannot be overridden."
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 "this is our second withdrawal in the last 24 months. The previous was submitted in July 2025, and enacted in August 2025.". 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: 207255840 ada
- D. Amount of this Treasury Withdrawal: 8503000 ada
- E. "C" plus "D" = 215758840 ada
- F. "A" minus "E" = 134241160 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 "An external financial auditor will scrutinize Scalus's finances and treasury management, with the goal to publish a resulting report in Q3 2027. It will be remunerated with funds explicitly allocated in this proposal for that purpose.", 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 provides information regarding the use of "Smart Contract Escrow" and "Independent Oversight Board" under the "Administration" 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:
- stake17yg2dle5tvyc4q7gy5cqel4sgd6xprjmm4u0jzzv8g0z9zgfz40xu
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.

- Tingvard646d1b3a…be43YesActive · term ends epoch 726Rationale
Tingvard judges the “Scalus: Cardano’s Application Platform for Building, Launching, and Scaling” governance action constitutional.
This governance action is properly framed as a Treasury Withdrawals action and must therefore be assessed under Article II, Section 6 and Article II, Section 7 of the Constitution, together with the applicable treasury guardrails in Appendix I.
The proposal satisfies Article II, Section 6, §1 by presenting the action in a standardized and legible format, with supporting off-chain documentation hosted through content-addressed IPFS references. It also satisfies Article II, Section 6, §2 by including a title, abstract, motivation, rationale, detailed workstreams, budget, administration model, risks, reporting structure, and supporting materials. Article II, Section 6 requires a URL and hash for the off-chain document, immutability, and sufficient rationale including title, abstract, justification, and supporting materials.
The action satisfies Article II, Section 7, §1 by specifying the terms of the withdrawal. The proposal identifies the purpose as funding Scalus as a Cardano application platform for building, verifying, launching, and scaling applications. It specifies a 12-month delivery period from July 2026 to June 2027 and requests 8,503,000 ada, including a 10% refundable contingency. It provides work packages, quarterly milestones, cost categories, FTE assumptions, audit allocations, refund conditions, and delivery expectations.
The action satisfies Article II, Section 7, §2 by disclosing prior treasury and community funding. Lantr Engineering discloses prior support through three Project Catalyst rounds and the 2025 Treasury Budget process, with total prior allocation of 1,085,692 ada and 888,384 ada withdrawn to date.
The action satisfies Article II, Section 7, §3 and TREASURY-02a by stating that the proposal follows the established 350M Net Change Limit and is within that boundary at the moment of submission. It also satisfies TREASURY-03a because the withdrawal is denominated in ada.
The action satisfies Article II, Section 7, §4 by allocating funds for periodic independent audits and oversight metrics. The proposal includes external security audits, independent financial audit, technical review and assurance, a security bounty program, quarterly technical reviews, quarterly reports, and a public transaction journal.
The action satisfies Article II, Section 7, §5 by designating administrators responsible for monitoring fund use and delivery. The proposal names an independent oversight board consisting of Chris Gianelloni, Matthias Benkort, and Riley Kilgore. The board co-signs disbursements, reviews milestones, can halt funding, and participates in permissioned actions under the escrow structure.
The action satisfies Article II, Section 7, §6 by stating that treasury funds will be held in separate auditable smart contract accounts, with auto-abstain DRep delegation and no Stake Pool Operator delegation. The proposal also includes a failsafe sweep returning remaining funds to the Cardano Treasury after expiration.
Tingvard therefore finds that the proposal satisfies the applicable constitutional requirements for a Treasury Withdrawals action.
Tingvard finds this governance action constitutional.
The proposal satisfies Article II, Section 6 and Article II, Section 7, including the requirements for withdrawal terms, prior funding disclosure, Net Change Limit compliance, periodic audits, administrator designation, and treasury custody protections.

Abstaining due a conflict of interest.
The proposal explicitly mentioned me as a member of its overseeing committee (which I wholeheartedly consented to). However, this could be deemed as presenting a conflict of interest and I prefer recusing myself from this vote.
