Ace Alliance finds the proposed "The first node in the browser; a Cardano USP" Treasury Withdrawal Governance Action Constitutional. Rationales are archived at https://github.com/ace-alliance/ace-voting/
"The first node in the browser; a Cardano USP" (gov_action1guz...596k4c) is a Treasury Withdrawal Governance Action requesting 4,600,000 ada to fund twelve months of engineering on Gerolamo, a TypeScript Cardano light node packaged as a browser extension, at a stated 5 FTE. As a Treasury Withdrawal it is governed by both the general proposal standards of Article II, Section 6 and the additional standards of Article II, Section 7. The proposer is Harmonic Laboratories, an independent R&D firm. Our review is confined to whether the action satisfies the Constitution. The strategic, competitive, and "USP" claims in the proposal text are matters of policy for DReps and the community to weigh, not questions of constitutionality.
Article II.6.1 (Standardized Format and Immutable Anchor). The action is submitted in a standardized, legible format and anchors an off-chain document at
ipfs://QmbQPrRhUUtvqNitu9mgC8esM3kXmR5iHGhEkLX1UZaLDywith hash444fb6a73db89d873a028eae85ce645f06965487901050bd46f6cacd8565eccc. The IPFS content addressing makes the document immutable and allows any observer to confirm the on-chain action matches the final off-chain version.Article II.6.2 (Sufficient Rationale). The proposal contains a title, an abstract, a detailed motivation and rationale, a budget breakdown, a milestone schedule with acceptance criteria, and supporting references. This satisfies the minimum content requirement.
Article II.7.1 (Terms of the Withdrawal). The proposal states the purpose (delivering a production-ready browser-based Cardano light node), a defined twelve-month delivery period (kickoff plus Q2 2026 through Q1 2027), and the relevant costs (5 FTE valued at 200,000 USD per FTE per year, plus a 15% refundable contingency, converted at 0.25 ADA/USD to a 4,600,000 ada total). Refund circumstances are specified through a contract-level "Failsafe Sweep" that returns unused funds to the Treasury after expiration and through the refundable nature of the 600,000 ada contingency reserve.
Article II.7.2 (Disclosure of Prior Treasury Funding). The proposal's own constitutionality checklist addresses Section 7.2 by pointing to a 2025 retrospective of past funding and deliverables. The constitutional requirement is disclosure, and the proposal provides that disclosure through its supporting materials. On the record before us, that is sufficient.
Article II.7.3 (Net Change Limit). A Net Change Limit must be set and must not be exceeded. The 350M ADA NCL for the period spanning epochs 613 to 713 is treated as set and active. The 4,600,000 ada requested here is well within that limit.
Article II.7.4 (Audit Allocation). The proposal allocates funding, within the FTE cost structure, for a periodic independent financial audit performed by a third party with no operational involvement in HLabs, conducted on a quarterly basis with a final assessment, and scoped to ex-post verification of treasury disbursements and traceability of fund flows. This satisfies the requirement to allocate ada for periodic independent audits and oversight metrics.
Article II.7.5 (Administrators). The proposal designates an Independent Oversight Board (Santiago Carmuega, Lucas Rosa, and Chris Gianelloni) responsible for reviewing milestones, co-signing disbursements, and halting funding if deliverables are not met. These named administrators are responsible for monitoring fund usage and ensuring deliverables are achieved.
Article II.7.6 (Custody and Delegation). Funds are held in the audited SundaeLabs treasury-contracts escrow (
treasury.ak/vendor.ak) in separate, on-chain-auditable accounts. The contract enforces auto-abstain DRep delegation and prohibits SPO delegation for all escrowed funds. This satisfies the separate-account and abstain-delegation requirements.Appendix I.3 (Treasury Guardrails). TREASURY-01a is met because the NCL was set by DReps via on-chain governance action exceeding the 50% threshold. TREASURY-02a is met because the 4,600,000 ada withdrawal does not exceed that limit. TREASURY-03a is met because the withdrawal is denominated in ada. No other guardrail group is engaged.
Ace Alliance finds the proposed "The first node in the browser; a Cardano USP" Treasury Withdrawal Governance Action Constitutional.
- Cardano Curia84feba94…6bd5YesActive · term ends epoch 799Rationale
Cardano Curia judges the “The first node in the browser; a Cardano USP” treasury withdrawal governance action constitutional, with one dissent focused on documentation/assurance strictness rather than the proposal’s intent.
What is being proposed
This governance action is a Treasury Withdrawal associated with the proposal titled “The first node in the browser; a Cardano USP” (linked to the legacy ID 4705a3…#0), intended to fund delivery of the described work program while satisfying the Constitution’s treasury-withdrawal standards.
Constitutional and guardrails consistency (procedural + stewardship)
Cardano Curia’s majority assessment is that this action meets the Constitution’s governance action standards and treasury-withdrawal requirements because (as described in the referenced rationale template):
- The proposal provides the required explanatory materials (title/abstract/rationale/supporting references) and specifies purpose, delivery period, costs/expenses, refund/close-out conditions, and prior treasury receipts disclosures.
- It includes an administrator/oversight structure responsible for milestone verification and controlled fund release.
- It allocates funds for independent audits and oversight metrics.
- It commits to holding treasury funds in separate auditable accounts, not delegated to an SPO, and delegated only to the predefined auto-abstain / abstain option while under administration.
- It states denomination in ada and asserts consistency with the active Net Change Limit guardrails at the time of submission.
These elements collectively support the majority view that the action is constitutionally admissible and aligns with the Constitution’s objectives of transparent self-governance and responsible treasury stewardship.
Value to the ecosystem (why the majority is positive)
The majority also finds the proposal’s direction—improving how users can verify and interact with Cardano (as implied by “first node in the browser”)—to be broadly aligned with strengthening accessibility and decentralization, so long as the promised reporting/audit controls remain enforceable via immutable references.
Minority dissent (why 1 vote was NO)
One Curia member voted NO on constitutionality as a strictness safeguard, emphasizing that treasury actions should be treated as unconstitutional if the final submission leaves any ambiguity around:
- Immutability/canonical-source locking (e.g., multiple versions, mutable links, or missing hashes), and/or
- Auditability specificity (e.g., insufficiently concrete audit scope, cadence, or traceability from spending → deliverables).
This dissent is not a rejection of the proposal’s intent, but a higher bar for documentary and assurance completeness at the point of on-chain finalization.
Determination (majority)
YES (constitutional) by majority, with an explicit expectation that the final submission strictly preserves the immutability and auditability commitments described above.
Cardano Curia finds the action constitutional by majority (4–1). The majority’s YES is grounded in the proposal’s stated adherence to the Constitution’s treasury-withdrawal standards—especially administrative oversight, segregated auditable custody, and independent audit provisions—while noting the single NO as a documentation/audit strictness safeguard to be resolved through immutability and assurance precision at final submission.

We consider this governance action to be constitutional.
This proposal is a Treasury Withdrawal Governance Action to withdraw ₳4,600,000 from the Cardano Treasury in support of Harmonic Laboratories’ “The first node in the browser; a Cardano USP.” In accordance with 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 an overview, rationale, technical background, milestones, budget, management structure, audit and reporting framework, risks, and a Constitutional Self-Assessment; we therefore determine that it presents sufficient information to be evaluated as a Governance Action. Regarding Article 2, Section 7, Paragraph 1, this proposal aims to develop “Gerolamo,” a validation node that runs in a browser, and details a 12-month implementation period, budget breakdown, funding release per milestone, repayment conditions, a fund repayment mechanism, and contingency funds. It also explains specific deliverables and acceptance criteria, including a browser-based storage layer, network layer, query API, distribution of browser extensions, and technical documentation. Regarding Article 2, Section 7, Paragraph 2, it is stated that Harmonic Labs has not received ADA from the Cardano Treasury within the past 24 months. Regarding Article 2, Section 7, Paragraph 3, the requested amount for this proposal is ₳4,600,000, which falls within the 350M ADA Net Change Limit applicable to Epochs 613–713 at the time of submission. Furthermore, the requested amount for this proposal is stated in ADA, and the proposal uses a conversion rate of 0.25 ADA/USD for budget estimation. Regarding Article 2, Section 7, Paragraphs 4 and 5, the proposal details an independent oversight committee, the basis for independent financial audits, quarterly reporting, public transaction records, measurable adoption metrics, milestone verification, and suspension/resumption authority. It also explains the treasury escrow structure using SundaeSwap treasury contracts, as well as independent audits conducted by TxPipe and MLabs. Furthermore, Article 2, Section 7, Paragraph 6 details the use of “treasury.ak” and “vendor.ak” for separately managed treasury escrow contracts, delegation to the predefined always_abstain voting option, non-delegation to an SPO, and auditable on-chain transaction records. This structure is intended to align with the requirements regarding “one or more separate accounts that can be audited by the Cardano Community,” “not be delegated to an SPO,” and “must be delegated to the 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.
- 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_action1guz...596k4c" and title "The first node in the browser; a Cardano USP" 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 "Gerolamo, the first production-ready Cardano node that runs in the browser"
- The period for delivery of proposed activities "spans over 12 months, throughout which there will be several deliveries and demos."
- The relevant costs and expenses under the heading "Budget Breakdown"
- The language regarding circumstances under which funds may be refunded to the Cardano Treasury is somewhat vague, such as "Sweep early (return unused funds)" under the Budget Administration section, and a 15% refundable contingency.
While the refund circumstances could have been more clearly stated, we have determined that the information supplied just meets the criteria for 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 includes a link to an external document that provides a "full retrospective of past funding and deliverables". 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: 4600000 ada
- E. "C" plus "D" = 211855840 ada
- F. "A" minus "E" = 138144160 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 "As part of the operational overhead included in the FTE cost structure, the proposal incorporates a independent financial audit of fund flows, designed to ensure transparency, accountability, and verifiability of treasury fund usage.", 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 an "Independent Oversight Board" will act as an administrator, 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:
- stake17x3n2krrld46qms4f4hzqqxzjgaf59u3fecvl6eh8scmaacjqmvjw
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.
