Standards

[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

There is no existing implementation of TM Forum’s Agreement Management standard on any blockchain, including Cardano, meaning Cardano has yet to tap into the telecom industry’s standard practices for agreements.

We will demonstrate how Cardano can serve enterprise use-cases by conforming to an existing standard used by hundreds of companies worldwide. With this standard-compliant solution, Cardano could become a preferred platform for telco workflows and beyond.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

• MVP Agreement Management Component – A working implementation of the TMFC039 component running on Cardano. This includes the on-chain Plutus scripts and off-chain code (APIs and backend) that together realize all core functionalities of agreement lifecycle management (creation, update/versioning, termination, acceptance workflow, etc.).
• TMF API Integration Layer – Implementation of key TMF Open APIs related to agreements.
• Documentation: User Guide for telecom operators and service providers and developer guide with instructions on how to integrate.

Describe realistic measures of success, ideally with on-chain metrics.

• Technical Delivery: Working codebase released on schedule; percentage of TMF spec features implemented (aiming for 100% of mandatory API features in the MVP).
• Ecosystem Interest: Expression of interest from at least one telecom operator or vendor to pilot or adopt the solution.
• On-chain Activity: Number of agreements managed on-chain.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

We propose to implement TMFC039 Agreement Management — an enterprise standard used by 800+ companies — as a Cardano-powered application, strictly following the TM Forum specification for this component. This will be the first-ever blockchain implementation of this standard, proving Cardano’s ability to handle real-world enterprise workflows and opening the door for telecom and other industries to join the Cardano ecosystem.

The solution will comprise:

• Plutus Smart Contracts implementing the agreement lifecycle logic (agreement creation, versioning, negotiation, acceptance, and fulfillment). Each agreement will be represented on-chain, with state transitions (e.g., pending, active, renewed, terminated) governed by smart contract rules.
• Integration of TMF Open APIs: We will expose the standard TMF APIs for agreements (TMF651 Agreement Management API) and related processes (e.g. TMF701 Process Flow) on a front-end service layer, so external systems can interface using familiar REST calls. For instance, a “POST /agreement” API call will trigger a Cardano transaction that creates a new agreement on-chain, and “GET /agreement/{id}” will retrieve agreement details from the blockchain or off-chain cache.
• Workflow Orchestration: The system will incorporate agreement-related workflows and templates as outlined by TMF’s spec (for negotiation, approval, etc.), potentially leveraging the TMF701 Process Flow API to manage off-chain workflow steps while the smart contracts enforce on-chain state and signatures.
• Documentation: Comprehensive documentation, including API specs, smart contract docs, and integration guides, will be delivered.

The implementation will use the latest Plutus smart contract capabilities and align with relevant CIP Standards. For example, we will consider CIP-68 standards for on-chain metadata to represent agreement data in transaction outputs. By adhering to Cardano best practices (e.g., using reference inputs and inline datums from the Vasil upgrade for efficient on-chain state management), the solution will be secure, efficient, and up-to-date with Cardano’s tech stack.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

By delivering a working Agreement Management module on Cardano, we open the door for telecom operators, vendors, and even other industries that rely on agreements (e.g., supply chain, finance) to experiment with Cardano in a context they understand.

This has the potential of increasing On-chain Activity and Enterprise Adoption.

Every agreement recorded using our solution means a real business process is happening on Cardano — creating adoption, on-chain activity, and visibility in a billion-dollar industry

[Your Project and Solution] Capabilities & Feasibility

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?

I’ve spent over 10 years delivering complex IT solutions in telecom and finance, and today I’m a Senior IT Solution Architect in a telecom company. I know how to take big, industry-grade ideas and turn them into working systems that people actually use.

I’m also an EMURGO Certified Cardano Solution Architect and have built several blockchain projects — from Plutus smart contracts to full dApps — that are already running in the Cardano ecosystem. In fact, I’ve already delivered two successful Catalyst-funded projects, so I know the process, the reporting, and how to deliver on what I promise.

With hands-on experience in TM Forum Open APIs (the same standards this proposal is about) and deep knowledge of Cardano’s tech stack , I’m in a unique position to make this project a reality.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

₳10,000 – Developing the Plutus scripts and on-chain data models (estimated 1 Plutus Dev FTE for 3 months, including testing).

₳22,000 – Backend/API Development: – Implementing the TMF651/TMF701 API layer and middleware connecting REST calls to Cardano (estimated 2 BE Dev FTE for ~3 months, including testing).

₳8,000 – Depoyment Automation and Documentation - (estimated 0.5 DevOps FTE and 0.5 TechWriter FTE for 3 months).

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

Why this is a good use of funds:

1. High Leverage: The TM Forum ODA standard is used by over 800 companies globally, including most major telecom operators. Delivering a TMF-compliant Cardano module immediately opens a pathway to enterprise pilots, multiplying the impact of the investment.
2. Open Source & Reusable: All outputs (smart contracts, APIs, documentation) will be Apache 2.0 licensed, meaning the community can reuse and adapt the work freely—maximizing the long-term return on Catalyst’s investment.
3. Proven Delivery Track Record: I have already delivered two successful Catalyst projects, showing I can manage funds responsibly and deliver value to the ecosystem.
4. Cost Efficiency: The budget reflects local market rates in Romania, which are significantly lower than Western Europe or North America for the same skill level, meaning Catalyst gets more development hours per ADA spent.
5. Enterprise Impact: This project directly integrates Cardano into established enterprise workflows, creating on-chain transaction volume and visibility in the telecom sector—an industry with high transaction volumes and stringent compliance needs.

For just ₳40k, the Cardano community gets a ready-to-use, open-source enterprise component that could unlock pilots with global telecom operators — multiplying the value of this investment many times over
