Mention your open source license and describe your open source license rationale.

We will release this project under the MIT License, one of the most permissive and widely adopted open-source licenses. By choosing MIT, we ensure that developers, and dApps can freely use, integrate, and extend our socket service with minimal restrictions. This maximizes adoption, encourages community contributions, and aligns with Cardano’s open and collaborative ethos.

How do you make sure your source code is accessible to the public from project start, and people are informed?

From day one, our source code will be hosted on a public GitHub repository under the MIT license. The repo will be actively maintained, with clear documentation, contribution guidelines, and regular updates. We will also announce progress and repository links on our community channels including: X, Telegram, Facebook and Github, so, developers are informed and able to engage, test, and contribute from the very beginning.

How will you provide high quality documentation?

We will provide high-quality API documentation by using Redocly, which allows us to create clear, interactive, and easy-to-navigate documentation. From the project start, all endpoints will be well-defined with request and response examples, error codes, and detailed descriptions.

The documentation will be continuously updated alongside the codebase, ensuring developers always have accurate and up-to-date references.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Problem We're Solving

On Cardano, getting real-time DEX data is fragmented and inefficient. Each DEX like Minswap or SundaeSwap forces developers to parse data directly from the chain. This means builders keep reinventing the wheel just to fetch and normalize basic pool and price data. They also face inconsistent price calculations, high latency from polling-based APIs, and real headaches when scaling across multiple DEXes.

This slows down innovation and makes it harder to build reliable trading bots, DeFi dashboards, or analytics tools. We’ve hit the same wall ourselves while building an arbitrage bot, pool monitor, and scam token alert, each time duplicating the same heavy lifting around DEX data. With our solution, builders cut down on infrastructure costs, speeding up build time, and reducing ongoing maintenance.

Solution Details

We propose to build and operate a lightweight Cardano socket for pool and price data that is an open-source WebSocket service that streams real-time, standardized data from Cardano DEXes. Instead of every project reinventing the same infrastructure, developers will be able to connect to a single, spend time building their own business.

For this funding round, our focus will be Minswap and SundaeSwap, delivering:

1. On-chain pool data: token reserves, swap fees, LP token supply, token metadata (fetched via off-chain indexer + synced with chain events).
2. Price feed: live spot prices with sub-second latency, supporting multiple pricing strategies (mid-price, last-trade price).
3. WebSocket channels: subscribe by trading pair, pool, or full DEX, each stream pushed in JSON format with lightweight payloads.
4. Public demo: a dashboard showing real-time prices of top pairs, built using the same socket.

Technical approach:

1. Data indexing powered by a modular adapter layer, where each DEX integration runs as a connector module.
2. Socket service built on Node.js + WebSocket, backed by PostgreSQL and Redis cache for real-time push.
3. Designed for horizontal scaling so the service can handle thousands of concurrent connections.

This setup reduces the need for every developer to maintain their own blockchain parser or pool indexer, saving infrastructure costs, build time, and ongoing maintenance effort.

[Your Project and Solution] Impact

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

Positive Impact

Our socket makes real-time DEX data accessible and standardized, which lowers the barrier for anyone building on Cardano DeFi. Instead of every project running their own indexers and price engines, builders can plug into a shared open-source service. This directly cuts infrastructure costs, reduces build time, and helps developers focus on delivering real user-facing value. Since the project is fully open source, teams also have the freedom to run the socket on their own infrastructure, ensuring flexibility, independence, and trust.

Value to the Cardano Community

By removing duplicated effort across projects, we accelerate innovation in DeFi, trading bots, risk management tools, analytics dashboards, and more. Smaller teams and independent builders who lack resources for heavy infrastructure will especially benefit. Our service acts as a common backbone that strengthens the Cardano DeFi ecosystem.

[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?

Proven Capability

TEX Labs has a strong track record in the Cardano ecosystem, achieving awards in scientific research competitions, hackathons, and organizing workshops/community events. These activities have built trust and provided direct insights into user needs.

Team Competence

The core team consists of three key members with projects funded in Funds 11, 12, and 13. Each member brings over 5 years of software development experience, more than 2 years of experience in developing and operating Cardano Blockchain infrastructure, and over 4 years in full-stack software development (microservices, clean architecture, database optimization, caching, message brokers). The team is proficient in Haskell/Plutus, Rust, Aiken, and modern frontend/backend technologies. They have successfully delivered multiple Cardano projects implementing CIP-25, CIP-30, and CIP-68, ensuring high reliability in real-world environments.

Feasibility Validation

We build for the real needs of the community. The roadmap begins with an MVP focused on critical “user jobs,” followed by rapid iterations with public releases and open demos. Success metrics are clearly tracked (active users, processed transactions, latency, error rates) and refined based on feedback.

Transparency and Accountability

We adopt an open-source development approach from the start:

• A PoC contains a fetch service for pools, tokens and prices has been created to demonstrate our capability: https://github.com/Tech-Expansion/tex-trading-bot-poc
• Regular progress updates (bi-weekly or monthly) with direct changelogs
• Milestone-based delivery with verifiable outputs before moving to the next phase
• Transparent financial reports with spending tied to each milestone

With a community-driven design, disciplined engineering, and transparent operations, TEX Labs is ready to deliver the project with reliability and accountability.

[Final Pitch] Value for Money

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

We believe this project delivers strong value for money to the Cardano ecosystem. With a budget of just 81,187 ADA, it is highly cost-effective given that we are building a critical infrastructure service that streams token prices directly from multiple DEX pools in real time. The cost already includes team salaries and infrastructure services, yet the output is a foundational utility that any developers or dApps can seamlessly integrate.

Instead of each project building its own fragmented indexer, we focus on creating a shared, open, and scalable pipeline. By running our own optimized indexers and socket layer, we reduce duplication, cut costs, and enable faster innovation across the ecosystem. Developers no longer need to waste time reimplementing the same infrastructure, they can focus on building smarter trading tools, DeFi apps, and analytics dashboards.

This isn’t just a socket for one use case. The indexers, APIs, and socket infrastructure are reusable modules that can support bots, wallets, DeFi dashboards, and other Cardano-native tools. We design with scale in mind, so thousands of users and projects worldwide can benefit.
