概要
SIPO DRepレビュー支援用の日本語作業訳です。正式な内容はHydra Voting上の英語原文を参照してください。
MLabsは、Cardano Transaction Library（CTL）について、JavaScript/TypeScriptインターフェース、Koios backend、四半期ごとのdependency updatesとDijkstra hard fork準備を行うため、3,226,648 ADAを求めています。CTLはAlonzo期から使われているoff-chain transaction-building libraryで、Indigo、Clarity、Cardano Racers、Noble Steed Games、SingularityNet等での利用が示されています。SIPOとしては、JS/TS開発者への開放、query backend多様化、Dijkstra readinessは公共インフラとして価値があると見ます。一方で、Intersect Open Source Committee Tooling Sustainability Programや過去Catalyst/IOG資金とのscope分離、3.22M ADAという大きな予算、KoiosでOgmios forwardingが必要な範囲、JS/TS bindingsの保守責任、Dijkstra testnet availability依存、NoWitnessLabs auditの実質性、Treasury repayment Noに対するADA価格上昇・scope縮小・未使用資金保護を確認する必要があります。

CTL is a foundational off-chain transaction-building library that has been part of the Cardano developer toolkit since the Alonzo era and has historically been the first library to ship support for new ledger features. It is in production use by Indigo, Clarity, Cardano Racers, Noble Steed Games, SingularityNet, and others, several of whom maintain their own forks. Today CTL is reachable only from PureScript. That keeps it out of the hands of the largest population of Cardano developers (those writing JavaScript and TypeScript) and concentrates maintenance on a smaller community than the library deserves. The library also needs to keep pace with Cardano's protocol roadmap, including preparation for the Dijkstra hard fork (Protocol Version 12, expected Q1–Q2 2027). This proposal funds three work packages: 1. **JavaScript/TypeScript Interface** — opens CTL to JS/TS developers without requiring them to learn PureScript. 2. **Koios Backend** — adds Koios as a first-class query layer alongside the existing Blockfrost and Kupo+Ogmios options. 3. **Quarterly Maintenance and Dijkstra Hard Fork Preparation** — funds disciplined dependency-bump cycles and the Dijkstra-readiness work CTL needs during the budget period. This work supports Cardano's vision of being the most secure, reliable, and censorship-resistant blockchain for mission-critical applications by lowering the barrier to entry for builders and keeping foundational tooling current with the protocol. CTL has prior funding from IOG, ecosystem adopters, and Project Catalyst Funds 8, 9, 10, 11, and 13. It is currently under separate review by the Intersect Open Source Committee's Tooling Sustainability Program, which is expected to cover core maintainership and Van Rossum hard fork work. This proposal is scoped to work that program does not cover: net-new feature development (WP1, WP2) and forward-looking maintenance tied to the 2026/early-2027 cycle (WP3).
