[Campaign Category] Category Questions

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

Most analytics tools are essentially data aggregators - they collect and information but don't understand it. At best they show "you have 1000 ADA in contract X" but can't tell you that actually means: "You're earning 4.2% APY in Liqwid's lending pool at 2.5x collateralization". We, on the other hand, without prior Catalyst funding:

• Don't just label transactions, but understand their effects and intent.
• Work on the patterns that emerge on-chain, no 3rd party cooperation needed.
• Derive everything from the blockchain itself, not proprietary APIs - truly decentralized

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

• Our MVP will demonstrate semantic translation in action: from any Cardano transaction hash to a clear, high-level understanding.
• It will prove protocol understanding by accurately interpreting transactions from major protocols using our predicate system.
• Users can connect their wallets to see DeFi activity with natural language descriptions, true cost basis, and performance metrics.
• Available to all from day one, showing this works at scale.

Accessed on our website exura.org with code available at our github github.com/ExuraLabs

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

We should be able to:

• Interpret 70%+ of major Cardano DeFi transactions.
• Cover protocols representing 70%+ of DeFi TVL.

Success means proving semantic intelligence works and gains organic adoption from users and projects.

This translates into a lower entry barrier for DeFi adoption across the ecosystem, although this impact is hard to measure directly on chain -for now.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

We’re building a fully functional DeFi dashboard powered by a novel, Cardano-specific approach, with the underlying library and backend inferring every intent from on-chain data only, without the need for permission, resources, or support from any protocol team.

The Core Innovation: Declarative Predicate System

Instead of hard-coding a custom interpretation for each protocol, we define high-level, reusable predicates — small building blocks that describe specific transaction conditions.

By composing these predicates, we can define complex operations for any protocol without starting from scratch.

Each predicate is:

• Declarative: Describes what to detect, not how to detect it
• Reusable: Works across different protocols where the same concept appears
• Composable: Combine multiple predicates to describe complex actions

Why This Works on Cardano

Cardano’s eUTxO model is ideal for this approach because:

• All state changes are explicit in transactions
• Transaction outcomes are fully determined by inputs
• No hidden side-effects like in account-based models

This means every condition a predicate needs can be found directly on-chain, enabling transparent, deterministic interpretations at scale.

[Your Project and Solution] Impact

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

Our goal is to make Cardano DeFi truly comprehensible through semantic intelligence.

The MVP will let users see every transaction in plain language, track real performance from on-chain data, and make informed decisions with confidence. This lowers barriers for new users to start transacting and increases protocol engagement.

For developers, we provide a library of open-source, reusable predicate patterns that work across protocols.

Cardano’s eUTxO model enables deterministic interpretation unmatched on other blockchains, and by open-sourcing the engine, pattern library, and language generation system, we expect adoption across wallets, dashboards, and protocols, catalyzing a shift where semantic understanding becomes the standard, attracting more users and developers to Cardano.

[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?

We’ve already built an early predicate-based proof of concept interpreting transactions from a few Cardano protocols. Hundreds of sample transactions have been processed with solid accuracy and stable performance, giving us confidence in the approach.

Validation Plan

• Test on large, varied sets of real transactions
• Run an open beta for clarity and usefulness feedback
• Benchmark speed and scalability as usage grows
• Share all code and data publicly for transparency

Accountability

• Public GitHub and open issue tracking
• Milestone demos for the community
• Community involvement encouraged

Our goal is straightforward: deliver a working product, prove it on real data, and refine it with community input.

Allocation by workstream (across the project)

• Core engineering & predicate development | ~74% (₳63,200)
  • Protocol handlers, predicate library, validation harness, performance work.
• Frontend dashboard (Angular) | ~15% (₳12,900)
  • Portfolio, insights, APR/IL/PnL indicators, UX polish.
• Data pipeline + infra/tooling | ~11% (₳8,900)
  • Software and licencing costs, CI/CD, test runners, hosting and monitoring.

No marketing or speculative spend. Funds go to build, validate, document, and demonstrate a working MVP.

[Final Pitch] Value for Money

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

This proposal funds the development and validation of an open-source semantic intelligence layer that explains any Cardano DeFi transaction in plain language using only on-chain data. Our approach uses a declarative predicate system to interpret protocols without custom integrations, with supporting techniques like entry-point tracking to scale portfolio analysis ecosystem-wide.

If successful, this could be adopted across wallets, explorers, dashboards, etc, setting a new UX standard. Even partial success delivers:

• Thousands of labeled transactions for future research
• Documented algorithms and reusable code
• Open-source libraries for the ecosystem
• Lessons learned that save future development time

Compared to fragmented, closed-source efforts costing much more, our lean team uses existing Cardano infrastructure, shares results openly, and minimizes duplication.

Risk vs. Reward

• Best case: Exura makes Cardano DeFi understandable by default: the engine infers actual transaction intent, directly from eUTxO 🔥
• Expected case: Reusable solutions and valuable insights
• Worst case: Detailed documentation of limitations to guide future work

In any case, Cardano gains a low-cost, high-leverage innovation uniquely suited to its eUTxO model, with potential first-mover advantage in making blockchain understandable.
