이 제안은 다음 문제를 해결하는 데 목적이 있음.

Cardano 생태계는 주로 Haskell과 JavaScript용 개발 도구와 라이브러리를 제공해, Python 개발자들이 플랫폼에 참여하는 데 큰 장벽이 존재함.

이로 인해 Cardano 개발자 커뮤니티의 성장과 다양성이 제한되고 있음.

또한, 기존 도구들은 외부 serialization 라이브러리에 의존하는 경우가 많아 개발 과정이 복잡해지고, 추가적인 오류 발생 가능성이 있음.

네이티브 Python 라이브러리가 없어 Cardano 인프라와 원활하게 통합된 개발 환경이 부족해, 개발자들이 효율적으로 애플리케이션을 구축하고 배포하는 데 제약이 있음.

이를 해결하기 위해 여러 프로젝트가 진행 중임.

1. **Cardano-Tools Python Library**는 Python 개발자용 도구를 확장 및 업데이트하여 최신 CLI 기능(리더십 슬롯 계산, 다중 서명, 메모리풀 쿼리 등)을 Python API에 래핑하고, Cardano Wallet 백엔드 기능을 85% 이상 지원하도록 확장하며, 단위 테스트 커버리지를 높여 안정성을 강화하는 작업을 진행 중임[1].

2. **cardanopythonlib**는 Cardano 블록체인과 상호작용할 수 있는 Python 라이브러리로, 키 생성, 트랜잭션 생성 및 서명, 온체인 제출과 확인 기능을 제공하며, 최소한 cardano-cli가 필요하고 cardano-node 실행 시 더 많은 기능을 활용할 수 있음[2].

3. **cardano-tools**는 Python 3.9 이상에서 작동하는 Cardano 블록체인 인터페이스 도구 모음으로, 노드, CLI, 월렛 서버와 상호작용하는 객체를 제공하며, 로컬 또는 도커 환경에서 cardano-node 및 cardano-wallet을 실행할 수 있음[3].

4. 최신 제안으로는 **현대적이고 완전한 기능을 갖춘 Python SDK 개발**이 추진되고 있어, 기존 라이브러리의 구식 문제를 해결하고 Python 개발자들이 Cardano 플랫폼을 더 쉽게 활용할 수 있도록 지원할 예정임[4].

5. 특히 **PyCardano**는 외부 serialization 도구(cardano-cli, cardano-serialization-lib 등)에 의존하지 않고, 독립적으로 트랜잭션 생성 및 서명을 수행할 수 있는 경량 Python 클라이언트로, 다양한 환경에서 빠르고 쉽게 설정 가능함[5].

요약하면, Cardano 생태계 내 Python 개발자 지원을 강화하기 위해 기존 라이브러리의 기능 확장과 안정성 개선, 그리고 네이티브 Python SDK 개발이 활발히 진행되고 있으며, 이를 통해 Python 개발자들이 Cardano 플랫폼에서 효율적으로 개발할 수 있는 환경이 조성되고 있음.

This treasury withdrawal funds **PyCardano** which will provide the following services: ​

PyCardano is a lightweight Python library that enables developers to interact seamlessly with the Cardano blockchain. It facilitates the creation and signing of transactions without reliance on external serialization tools, thereby simplifying the development process and broadening accessibility for Python developers. Given the dynamic nature of blockchain technology, particularly with Cardano's ongoing protocol upgrades and hard forks, it is imperative to maintain and update PyCardano to ensure continuous compatibility and functionality.​

This proposal aims to:

Ensure Compatibility: Regularly update PyCardano to align with the latest Cardano ledger rules and protocol changes, including upcoming hard forks in 2025.​

Enhance Reliability: Promptly identify and resolve bugs within PyCardano to maintain a robust and dependable library for developers for 12 months since the proposal is funded.​

Foster Community Engagement: Collaborate with the Cardano developer community to gather feedback, address issues, and implement improvements effectively.

This Treasury Withdrawal is submitted by Intersect on behalf of the vendor. The following sections; Abstract, Motivation, Rationale and Vendor Profile have been sourced from the approved proposal submitted by the Vendor as part of the Intersect budget process.

This treasury withdrawal funds one of 39 proposals to give effect to the approved budget info action for ₳275,269,340, administered by Intersect via gov_action1u9x73kwufaxa70lfy59g4ynwyrcsaxdcd0gxzzmh67s9fxq4j8hqqk2phgh. The information provided herein is intended to fulfill the spirit of the constitutional requirement for a treasury withdrawal info action by also providing the details of the proposed solution, alignment to the budget, and amount to be withdrawn from the Cardano Treasury.

This proposal aims to solve the following problem:

The Cardano ecosystem primarily offers development tools and libraries in Haskell and JavaScript, creating a significant barrier for Python developers who wish to engage with the platform. This limitation hinders the growth and diversification of the developer community within the Cardano ecosystem. Furthermore, existing tools often depend on external serialization libraries, complicating the development process and potentially introducing additional points of failure. The absence of a native Python library that seamlessly integrates with Cardano's infrastructure restricts the ability of developers to build and deploy applications efficiently.

### Project Solution

PyCardano is a Python library designed to facilitate interaction with the Cardano blockchain by enabling users to create and sign transactions without relying on third-party serialization tools. This independence makes PyCardano lightweight and easy to set up across various environments. ​

Developing PyCardano addresses the challenges mentioned above by providing a native Python library tailored for the Cardano blockchain. This initiative aims to lower the entry barrier for Python developers, fostering a more inclusive and diverse developer community. By eliminating the need for third-party serialization tools, PyCardano simplifies the development workflow, enhancing both efficiency and reliability. This project not only broadens the accessibility of Cardano to a wider range of developers but also encourages innovation and the creation of new applications within the ecosystem.​

By implementing this proposal, we anticipate the following outcomes:

Sustained Compatibility: PyCardano will remain compatible with the latest Cardano protocol versions, enabling developers to build and maintain applications without disruption.​ Although there isn't a clearly specified roadmap or hardfork for Cardano in the next 12 months, we know it is likely that there will be Leios and Midnight integration. These integration and changes will more or less require corresponding updates in PyCardano.

### Contract Management

A written off-chain Legal Contract will be created between the Vendor and the Cardano Development Holdings (CDH), as mandated by the constitution, and will be administered by Intersect. This will include details of the project delivery schedule and dispute resolution.

### Project Delivery

All milestones, acceptance criteria, payment amounts and expected delivery dates will be agreed between the Vendor and Intersect, acting on behalf of the CDH. The vendor will deliver according to the agreed-upon project schedule within the Legal Contract, of which the necessary information will be made public via the budget management platform via transaction metadata.

Defined by the milestones within a Legal Contract, the vendor will submit and attest milestone acceptance to the community, Intersect or 3rd Party Assurer.

Project progress will be monitored via Intersect's delivery assurance function which will be communicated to the community.

Acceptance of the above work is expected to be supported by a 3rd Party Assurer, who will be responsible for reviewing and signing off the work completed at each project milestone against the corresponding milestone deliverables detailed within the Legal Contract. This work is funded from a portion of this treasury withdrawal.

### Budget Management Tooling

To administrate treasury funds on-chain, Intersect will utilize the treasury management smart contract framework developed by Sundae Labs. The smart contracts have been [extensively tested](https://github.com/SundaeSwap-finance/treasury-contracts/tree/main/offchain/tests) including audits from TxPipe and MLabs. Examples of the usage of these contracts can be seen across mainnet described across Intersect authored [Blog 1](https://www.intersectmbo.org/news/smart-contract-mainnet-demo-a-step-toward-on-chain-treasury-withdrawals), [Blog 2](https://www.intersectmbo.org/news/smart-contract-mainnet-demo-day-two-update) and [Blog 3](https://www.intersectmbo.org/news/smart-contract-mainnet-demo-day-three-update).

Final mainnet validation test can be seen via the Disburse action within transaction: 0f591dc544ae14102dbb4a74d5311a6acffc1772b163d8b7a9656b9525950b17

With the confirmed treasury reserve contract address being: stake17xzc8pt7fgf0lc0x7eq6z7z6puhsxmzktna7dluahrj6g6ghh5qjr

#### Specifics

Intersect will utilize a single Treasury Reserve Smart Contract (TRSC), with many Project-Specific Smart Contracts (PSSC), managed by Intersect. Intersect's management consists of three 'admin' and two Intersect 'leadership' roles. An Oversight Committee consisting of five external, independent third-party entities will provide checks and balances on Intersect, and safeguard against errors and unilateral control. The administration of both TRSC and PSSCs will be managed by Intersect, with external oversight on certain actions from the Oversight Committee.

The Oversight Committee consists of Sundae Labs, Cardano Foundation, Dquadrant, Xerberus and NMKR. Their role is to independently verify key administrative actions using on-chain logic, ensuring accuracy and consistency without exercising discretion over governance decisions.

For all details on Intersect's configuration please see the **[Smart Contract Guide](https://docs.intersectmbo.org/cardano-facilitation-services/cardano-budget/intersect-administration-services/smart-contracts-as-part-of-our-administration)** on the knowledgebase.

The high level permissions are as follows:

- TRSC Fund and PSSC Modify

- Two of the three Intersect admins, two of the five trusted entities and one of the two Intersect leadership sign-off must authorize

- TRSC Disperse

- Two of three Intersect admins, three of five trusted entities and two of two Intersect leadership sign-off must authorize

- TRSC Pause and Resume

- Two of three Intersect admins, and one of two Intersect leadership sign-off must authorize

- TRSC Sweep

- One of three Intersect admins, and one of two Intersect leadership sign-off must authorize

- TRSC Reorganize

- Two of three Intersect admins and three of five trusted entities must authorize

#### Processes

Upon enactment of this governance action, funding for this project will be directed into the TRSC's stake account. All instances of TRSC and PSSC can not be staked with a SPO and will be delegated to the auto-abstain predefined DRep. From here funds will be withdrawn into a UTxO remaining at the TRSC.

When the Legal contract is prepared and the vendor is ready, funding for this project will be transferred using the Fund action to a PSSC. All milestones will be outlined within the metadata.

A dashboard will be available for the community to audit the TRSC or PSSC and track metrics related to this withdrawn ada as well as being immutably verifiable on chain.

The subsections; Contract Management, Project Delivery, and Budget Management Tooling described above cover the constitutional requirements specified in Article IV section 4 and 5.
