[Proposal Summary] Problem Statement

What is the problem you want to solve?

Currently in Sutra SDK, representing Plutus Datums & redeemers requires boilerplate code. SDK is also missing a testing framework to build & test transactions.

[Campaign Category] Category Questions

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

The MIT license places minimal restrictions on how developers and organizations can use, modify, and distribute the Sutra SDK. This removes all barriers to adoption, allowing both individual developers and enterprise teams to integrate the SDK into their projects without legal concerns or licensing compliance overhead.

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

We have already started working on this project though we were not funded in fund 13. we started contributing to codebase with public repository fom day 1.

Code is already public here - https://github.com/txbody-org/sutra-cardano

How will you provide high quality documentation?

We will be using Elixir HexDocs ( @doc , @moduledoc) to write documentation & guides for each module and function. HexDocs will compile this documentation and deploy to https://hexdocs.pm/

once package is uploaded to Hex package manager documentation is auto generated. here is example documentation of Elixir using Hex https://hexdocs.pm/elixir/introduction.html

we will have similar documentation generated using Hex

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

The Sutra SDK currently requires developers to manually write extensive boilerplate code for every Plutus contract interaction. For each contract, developers must:

• Manually define datum and redeemer types in Elixir, translating from Plutus specifications
• Create contract interface modules with repetitive validation logic
• Build custom testing setups

This manual process is error-prone, time-consuming, and creates maintenance overhead when contracts are updated.

Proposed Solution

1. Automatic Code Generation from Plutus Blueprints

      mix sutra.parse.blueprint   /path/to/blueprint.json

2. Comprehensive Testing Framework

• Emulator testing for fast unit tests with blockchain state simulation
• Yaci DevKit integration for realistic private network testing

[Your Project and Solution] Impact

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

• Reduced Onboarding Friction: New developers can simply use code generator to generate boilerplate code which allows developer focus on solving busines logic
• Standardized Best Practices: Auto-generated code follows established patterns, eliminating common integration bugs with manually written contract interfaces.
• Comprehensive Testing Culture: Built-in testing framework encourages thorough validation, leading to more reliable dApps that enhance user confidence in the Cardano 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?

We are the team with a strong foundation in Elixir & cardano development.

We have worked on a production ready Web3 project

• Iagon https://iagon.com/
• Nuvola https://www.nuvoladigital.io/

We are also composed of a team with strong knowledge on fullstack as well as mobile application development.

Our team involves in:

Cardano Development

• Piyush has worked extensively on cardano projects for more than five years. He is skilled in smart contract development using both Aiken and Plutus, and he is the author and core maintainer of the Cardano Elixir SDK (https://github.com/txbody-org/sutra-cardano )

Full Stack Development

• Aayush is an experienced Elixir developer with more than six years in software development. He has built fullstack applications and mobile apps, combining backend, frontend, and mobile expertise to create complete solutions. He is also a contributor to the cardano elixir sdk.

We are a team with a strong foundation in Cardano development, fullstack web, and mobile application development and bring deep technical expertise across multiple software domains. Our team has over five years of experience in Cardano projects, specializing in smart contract development using both Aiken and Plutus. We are also composed of a team with strong knowledge on fullstack as well as mobile application development.

The team's dedication to the Cardano ecosystem extends beyond funded projects. Despite the Sutra SDK not receiving funding in Fund13, the team continued development independently. The SDK is currently being integrated into the upcoming Nuvola Digital application, showcasing its practical value and the team's perseverance.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

Milestone 1: Automatic Code Generation from Plutus Blueprints

• Budget: 20,000 ADA
• Contributor: Aayush & 1 elixir Developer

Milestone 2: Testing Framework Emulator Trace & Private Network

• Budget: 20,000 ADA
• Contributor: Piyush & 1 Elixir dev

Milestone 3: Documentation & Project Closeout video

• Budget: 2,000 ADA
• Contributor: Aayush

[Final Pitch] Value for Money

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

The 42,000 ADA investment delivers extraordinary value by transforming manual contract integration from a 15-40 hour process into a 5-minute automated workflow via mix sutra.parse.blueprint. This 90%+ time reduction means developers can integrate contracts in minutes instead of hours, dramatically accelerating dApp development cycles.

Building on the proven Sutra SDK foundation, this extends existing infrastructure rather than duplicating effort, while the comprehensive testing framework eliminates the 10-40 hours typically spent on testing setup per project, serving the entire Elixir community with professional-grade automation.
