Financial Services
Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).
Our project introduces a new standard of transparency for social impact projects and RWAs by integrating Sonhatório with Reeve on Cardano. Every transaction, milestone, and supporting document is verifiably anchored on-chain and accessible via a public Transparency Portal and APIs. This leap in accountability boosts credibility and trust, helping projects attract more funding, scale impact, and set a replicable model for real-world financial and social transparency.
Describe what your prototype or MVP will demonstrate, and where it can be accessed.
Our MVP demonstrates end-to-end on-chain publishing of financial transactions, milestones, and supporting documents for social impact projects. Users can view verified events via the Transparency Portal and query data through read-only APIs. The prototype is accessible at https://reeve.sonhatorio.com with authenticated testing via https://keycloak.sonhatorio.com, proving technical feasibility and real-world applicability.
Describe realistic measures of success, ideally with on-chain metrics.
Success will be measured by onboarding at least 1 project with fully verifiable on-chain records within six months, publishing financial events within 24 hours, and ensuring ≥80% of transactions include supporting documents. Community engagement is targeted at 500+ monthly views of the Transparency Portal, while technical adoption is tracked via API queries and on-chain verification events, demonstrating credibility, transparency, and pilot feasibility.

Enhanced Version with Social Impact and Innovation Focus
Why Cardano & Reeve:
Tech stack:
Operational flow (How it works):
Please define the positive impact your project will have on the wider Cardano community
Absolute Trust: We ensure that every unit of currency invested in social projects and Real-World Assets is fully auditable, traceable, and transparent, building a strong bond between investors, donors, and beneficiaries.
Standardization and Scalability: We establish a replicable, scalable accountability model for impact projects and RWAs, accelerating best practice adoption and facilitating expansion into new regions and sectors.
Driving ADA Adoption: We promote the use of ADA as a trusted means to finance and validate real-world initiatives, embedding Cardano’s cryptocurrency directly into the socio-environmental impact value chain.
Open and Collaborative Governance: We provide open and accessible data for communities, media, researchers, and regulators, strengthening transparency, civic engagement, and knowledge generation for more effective public policies.
What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?
The Sonhatório platform is already operational, successfully managing fundraising and project administration.
Our team brings deep expertise across blockchain technology, finance, security, and product development.
We have full command of Reeve infrastructure components including Keycloak, Publisher/API/Viewer, and Traefik.
Our implementation plan includes a Proof of Concept (PoC) on testnet, a closed beta phase, and a rollout featuring a real-world pilot.
Milestone Title
Architecture, Security, and Prototype
Milestone Outputs
In this initial phase, we will focus on defining and designing the complete architecture that integrates the Sonhatório platform with Reeve. This includes detailed modeling and mapping of data flows between the two systems, as well as developing a Proof of Concept (PoC) on the Cardano testnet to validate the technical feasibility. We will also establish strict publication policies, role definitions, and secure key management protocols to ensure data integrity and compliance.
Acceptance Criteria
Deliverable: A fully functional prototype demonstrating the core integration capabilities, accompanied by a comprehensive architecture report documenting all technical decisions and security considerations.
Evidence of Completion
Projects with On-chain Trail: Starting with 1 pilot project, we aim to onboard and fully integrate at least 10 additional social impact and RWA projects within 06 months following the public launch. This growth will demonstrate the platform’s scalability and its ability to meet diverse real-world needs.

Milestone Title
Core Integration & Closed Beta
Milestone Outputs
During this phase, we will build and deploy the essential services for publishing (publisher) and consuming (follower/viewer) the on-chain events. We will also develop a basic Transparency Portal that will serve as the user interface for stakeholders to monitor projects and financial flows. Data importers will be implemented to facilitate smooth data ingestion. This beta release will be limited to a group of 10+ selected internal users, allowing thorough testing and security assessments to identify and resolve any issues.
Acceptance Criteria
Deliverable: A beta version of the platform with complete core integration, fully tested for security, stability, and functionality, prepared for initial deployment to selected real users, enabling feedback collection, performance assessment, and validation before public launch.
Evidence of Completion
Time from Fundraising to On-chain Event: We target a median processing time of less than 24 hours between when a financial event is captured and when it is published on-chain. This rapid turnaround ensures near real-time transparency and responsiveness for stakeholders.

Real-World Project Pilots
Milestone Outputs
This milestone focuses on onboarding at least one real social impact or RWA project to pilot the integrated platform with live data. We will conduct training sessions for project proposers and auditors to ensure proper use of the system and accurate data submission. This phase will validate the end-to-end workflow and demonstrate the practical benefits of on-chain transparency and accountability.
Acceptance Criteria
Deliverable: Comprehensive project reports containing accurate financial data, achieved milestones, and fully verified on-chain evidence, ensuring transparency, auditability, and trust for stakeholders and potential investors.
Evidence of Completion
Percentage of Transactions with Attached Evidence: Our goal is for at least 80% of all recorded transactions to include verifiable supporting documentation such as invoices, receipts, or signed statements. This level of evidentiary support enhances trust and auditability.

How does the cost of the project represent value for the Cardano ecosystem?
This proposal delivers a tangible, real-world use case for financial and impact data integrity, enabling verifiable records on the Cardano blockchain. By anchoring both financial transactions and impact milestones on-chain, it establishes a transparent and auditable record that donors, investors, regulators, and the public can independently verify.
The implementation will directly contribute to increased utility and transaction volume on the Cardano network, driven by social impact and RWA (Real World Asset) projects — two segments with high potential for sustainable adoption and reputational value for the ecosystem.
Moreover, the solution is intentionally designed for replicability. Through the release of open APIs, adapters, and documentation under an MIT license, other platforms and organizations will be able to adopt the same model, reducing barriers to entry for transparency in funding, accelerating network effects, and fostering innovation on Cardano.
In essence, this investment in Sonhatório + Reeve is not only about solving a pressing trust problem for impact projects — it is also about establishing Cardano as a credible, go-to infrastructure for transparent, auditable, and high-impact financial ecosystems.
