Cardano Treasury Explorer. An open data source for tracking treasury spending on the Cardano blockchain. Bringing transparency and accountability to community funds.

ADAspending provides a comprehensive solution for community members to understand how treasury funds are allocated and utilized within the Cardano ecosystem.

• Track Funds: Monitor how treasury funds are distributed across different projects and initiatives within the Cardano ecosystem.

• Review Proposals: Explore funded proposals with detailed information about recipients, requested amounts, and project outcomes.

• Analyze Data: Gain insights through interactive visualizations showing treasury spending patterns and fund allocation trends.

• Search & Filter: Easily search and filter through funding data by categories, recipients, and time periods to find exactly what you're looking for.

• Historical Trends: View historical spending data and trends over time to better understand the evolution of Cardano treasury management.

• Community Insights: Understand how the community is making decisions about fund allocation and which areas are receiving the most support.

Why ADAspending Matters? Community governance and treasury management are central to Cardano's decentralized ecosystem. ADAspending provides the transparency needed for community members to understand how funds are allocated.

• Public access to comprehensive funding data
• Searchable database of all proposals and recipients
• Interactive visualizations and data analytics
• Historical trends and timeline analysis
• Connections between projects, recipients, and outcomes
• Detailed insights on fund allocation and outcomes

How ADAspending Works

1. Data Collection: We collect and process data directly from the Cardano blockchain and public treasury records.

2. Data Analysis: Our algorithms categorize and analyze the data to identify patterns and trends in spending.

3. Visualization: Data is transformed into intuitive charts and graphs that make complex information easy to understand.

4. User Access: You get access to all this information through our user-friendly dashboard and search tools.

The Cardano community and ecosystem need a unified, transparent, and user-friendly platform to explore and analyze how treasury funds (money) are being allocated, spent, and tracked over time.

While some data is available on platforms such as Cardano block explorers, GovTool, Intersect website, gitbook, websites and google spreadsheets, powerpoints and documents, it remains fragmented, difficult to navigate, and often inaccessible to the broader Cardano community or outsiders.

With this proposal, we address the critical need for financial transparency and community accountability by creating ADAspending.com - an open data portal that aggregates and visualizes treasury spending on the Cardano blockchain in a user-friendly and accessible interface.

Inspired by USAspending.gov, ADAspending.com empowers voters, proposers, researchers, the community, and stakeholders to follow the flow of ADA from the treasury to proposals, with on-chain verification, cross-referencing, and analysis of the information.

This project brings great value to multiple segments of the Cardano ecosystem by increasing transparency, accountability, and trust in the treasury system, a fundamental element of decentralized governance. Among the benefits, we highlight by segments:

• Benefits for Community Members and Voters: Get a clear and easy-to-use view of where treasury funds are being directed and going, how much is being spent, and who is receiving the funding, helping them make more informed decisions when voting or delegating their voting power to a DRep in Cardano’s decentralized governance.

• Benefits for Project Proponents: Access historical funding data, identify trends, and compare their proposals to previous successful (and unsuccessful) initiatives.

• Benefits for DReps: Use the platform to track funding performance and outcomes, improving decision-making and voting strategies.

• Benefits for Researchers, Auditors and Finance Members: Monitor and track the delivery of funded proposals and compare them to what was promised, facilitating better accountability and reporting.

• Benefits for SPOs and Developers: Leverage structured, publicly available data for analytics, governance research, dashboards, and community tools.

ROI to the Cardano Community

• Enhanced Treasury Transparency: Promotes trust in the on-chain governance process by offering a single, open-source interface to track every ADA spent.
• Increased Community Engagement: Lowers the entry barrier for new community members to understand treasury flows.
• Better Funding Decisions: Helps avoid waste, identify high-performing proposals, and support more impactful initiatives, optimizing treasury ROI.
• Support for Governance Evolution: As Cardano matures toward full on-chain governance, ADAspending.com will become a vital tool for monitoring public resource allocation in a decentralized way.

I'm attended at Cardano's global workshop on CIP-1694 Governance in person in Edinburgh UK (July 2023) and participanting in Cardano Constitutional Workshop in Kenya (November 2024) and Cardano Constiututional Convention in Buenos Aires / Argentina (December 2024).

I'm already organized several official Cardano events for the community including conferences, exhibits, Cardano summits, workshops, CIP-1694 workshops and Intersect workshops.

Our team has previously been approved in some projects on Catalyst and the projects were successfully completed and with a project closure report containing all proof of delivery.

Our team is composed of developers, UX/UI, Marketing, SEO, Marketing, Business and we developed the largest media coverage platform Cardanofeed.com and the Cardano Ecosystem project directory (approximately 1,200+ projects).

After initial development, maintenance costs will be much lower. Upon completion of the project, maintenance and support costs will be simplified and reduced to a reduced cost of $50K/year. New features would be budgeted separately according to scope and work hours. And we will be able to make specific scopes for including improvements and new features to the platform. The project will be fully 100% open source.

Explore new use cases for governance tools for decentralized governance, accountability on the Cardano blockchain, establishing more transparent community governance that is accessible to all.

While ADAspending.com is a new initiative, it is built upon clearly expressed needs from the Cardano community regarding treasury transparency, governance tooling, and accountability. The following points demonstrate a strong foundation of community interest and alignment:

• Community Conversations & Feedback: In discussions across X Twitter, Telegram groups, and Discord channels, there have been recurring calls for more accessible, centralized tools to explore funding data. Improved transparency into how treasury funds are being spent. Dashboards that make it easier to track proposal outcomes and voting patterns.

• Alignment with Cardano Governance Goals: ADAspending.com directly supports Cardano Governance and Voltaire objectives, particularly those related to accountability of funded proposals, on-chain governance tooling and Informed community decision-making.

• Support from Community Tooling Ecosystem: ADAspending.com complements other existing tools such as GovTool, GovernanceSpace, CardanoScan, Tempo, AdaStat, 1694.io, cGov - not replacing them, but bridging gaps and offering deeper visibility across proposals, spending, and recipients.

• Benchmarking - USAspending.gov: The project is modeled after USAspending.gov, a trusted and widely used transparency platform in the U.S., making this a proven concept with global relevance.
