[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).

1. Unified Multi-DEX Data: First solution on Cardano to aggregate pool info, TVL, token reserves, and liquidity from multiple DEXes in real-time, providing a solid foundation for arbitrage bots and alert bots.
2. AI Normalization: Automatically cleans and standardizes data using AI/LLM, enabling data crawling from DEXes that don’t yet offer public SDK/API.
3. Flexible Deployment: Supports hosted via Docker Compose or cloud SaaS, giving devs full control or plug-and-play access. (Unlike Charli3, which only provides an API without hosted option.)
4. Developer-Focused: Combines WebSocket streaming and REST API in one platform, no previous open-source service on Cardano offers this combo.
5. Modular Architecture: DEX connectors and cardano-db-sync run independently, allowing scalable expansion to new DEXes without downtime.

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

Current Stag is a Proof-of-Concept with working code.

Repositories:

• Data Sync Repo: Fetches and indexes pool data from Minswap. (https://github.com/Tech-Expansion/tex-pool-syncer)
• Bot Repo: Uses indexed data to perform trading and alerts on Telegram. (https://github.com/Tech-Expansion/tex-trading-bot-poc)

MVP Goal: Demonstrate the full pipeline: data sync → data processing → end-user consumption, showing real-time aggregation, normalization, and usage of DEX data.

Accessible: Developers can clone repos, test data streams, end user can try with trading bot on Telegram (@poc_tex_bot - preprod environment).

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

Since TexStream does not generate on-chain transactions, success is measured via developer adoption, request volume, DEX coverage, and active contributions

• Users: 20–50 active developer users in first month from MVP launch.
• Requests: ~50,000–100,000 WebSocket/API requests per day at MVP launch.
• DEX coverage: Start with Minswap & SundaeSwap, expand to Wingriders and other DEXes within 6 months.
• Latency: Sub-second updates for pool prices and liquidity changes.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Problem We're Solving

Developers building on Cardano face a familiar headache: every DEX reports pool data differently, and fetching TVL, token reserves, liquidity or swap prices requires building custom crawlers, parsers, and indexers. Across teams, this repetitive work consumes hours, compute, and storage which slow innovation and create redundant infrastructure. We’ve hit this wall ourselves, building arbitrage bots, pool monitors, and token alert systems, repeating the same heavy lifting every time.

TexStream solves this problem once and for all. It’s an open-source, plug-and-play socket service that aggregates, cleans, and AI-normalizes pool and price data from multiple DEXes. Developers can subscribe to real-time WebSocket streams by trading pair, pool, or entire DEX, receiving standardized, lightweight JSON payloads with sub-second latency.

TexStream is designed to be flexible: run it locally via Docker Compose for full control, or use our cloud SaaS with simple subscription tiers (all free in first year), no setup required. Our main users are developers, but if you’re not one, don’t worry: by supporting TexStream, you’re helping build the foundation for better DeFi tools, dashboards, and trading bots on Cardano. Vote for us, and you’re backing the infrastructure that makes the ecosystem faster, smarter, and more reliable. Our team really appreciates that.System overview

Key features include:

• Unified Pool Data: token reserves, LP supply, TVL, swap fees, token metadata.
• AI/LLM Normalization: crawled raw data is formatted automatically, removing inconsistencies and errors.
• Flexible Deployment: run locally via Docker (hosted mode) or on the cloud with subscription tiers, free tier for first 20,000 requests/day in the first year.
• Adaptable Architecture: modular DEX connectors, independent cardano-db-sync nodes, allowing easy integration of new DEXes.

Performance and Scalability: TexStream is built for heavy load. PostgreSQL + Redis caching ensures fast reads and writes, and horizontal scaling allows handling hundreds of requests per second. Lightweight API/WebSocket connections prevent bottlenecks, and modular adapters let us scale DEX integrations independently.

In short, TexStream eliminates repetitive data processing, saves infrastructure costs, and lets developers focus on building dashboards, trading bots, analytics, or other DeFi products without worrying about messy pipelines, inconsistent data, or scaling headaches.

[Your Project and Solution] Impact

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

Positive Impact

TexStream turns the messy, “reinvent-the-wheel” world of Cardano DEX data into something anyone can plug into. Developers no longer need to wrestle with crawlers, parsers, or weird JSONs, our open-source socket and API give them clean, real-time data ready to use. It saves time, money, and sanity, while letting teams focus on the fun part: building cool DeFi apps. And yes, if you like control, you can still run it on your own servers.

Value to the Cardano Community

By cutting out repeated effort across teams, TexStream acts like a backbone for Cardano DeFi. Trading bots, dashboards, analytics tools, small teams and solo builders suddenly have the same firepower as the big players. It’s infrastructure that actually makes the whole ecosystem better, and way less painful.

[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, prices and trade has been created to demonstrate our capability:
  • https://github.com/Tech-Expansion/tex-pool-syncer
  • 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.

[Final Pitch] Value for Money

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

We believe TexStream offers exceptional value for the Cardano ecosystem. With a budget of just $33,280 (~79,236 ADA), the project is extremely cost-effective, especially in today’s market where ADA prices have dropped. Despite the modest budget, we are fully committed to delivering a high-quality, reliable, and scalable infrastructure that streams token prices and pool data from multiple DEXes in real time.

Instead of every project building its own fragmented indexer, TexStream provides a shared, open-source, and reusable pipeline. This reduces duplication, cuts costs, and enables developers to focus on building smarter trading tools, dashboards, DeFi apps, and other Cardano-native products.

We understand the stakes, this is a product we also hope to monetize in the future, so we are fully motivated to make it robust, performant, and developer-friendly. Every line of code, every WebSocket message, and every API endpoint will be crafted with care, ensuring that the Cardano community gets a dependable, high-quality foundation for DeFi innovation, all at a surprisingly modest cost.
