Solution: Upgrade the hydra auction reference implementation into a production-ready app deployable on mainnet and add UX improvements for commercial viability. Develop a general SDK for similar applications.

Solution: Proposed changes:

• Modularize & split the codebase
• Simplify the constraints interface used for transaction building
• Update dependencies and tooling software

Solution: We propose creating a light wallet targeted at developers, testers and power users. It will provide unique features missing in mainstream wallets.

Solution: Our solution proposes implementing the same onchain validator in multiple languages, developing a language-agnostic test suite to test the equivalence of validators, and measuring performance.

Solution: We aim to integrate light wallet functionality into the open-source Godot game engine, thereby providing game developers with the tooling and infrastructure needed to quickly integrate Cardano.

Solution: Configuration-based mechanism for specifying DApp data types and associated tooling for producing type libraries with common operations for Rust, Javascript and Aiken language environments.

Solution: A blockchain-based name resolution service that provides a migration path from DNS to an alternative with much stronger security, transparency, anti-censorship, and anti-centralization guarantees.

Solution: Define and reuse DApp logic via annotated CEM-machines, resulting in free implementations for on-chain scripts, tx building/ submission/resubmission on L1/L2, tx parsing/indexing, specs, and tests.

Solution: We propose creating a new CIP that extends CIP-30 with new query methods and which allows for abstraction from the CBOR encoding of data.

Solution: MLabs will build a persistent testnet mimicking peak transaction volumes and complexity, and maintain it for 6 months aiming for eventual self-sustainability and community recognition and persistence.

Solution: We will create a NixOS configuration and scripts to generate the files needed for SPO deployment. We will leverage nixos-anywhere to make our NixOS configuration deployable on any Linux-based machine.

Solution: We propose creating new NixOS modules where none exist, and a repository for “super modules” (using pinned versions) that will import them thereby simplifying complex interactions.

Solution: Create a PureScript compiler backend for UPLC. PureScript has a strict runtime and almost all Haskell features. Some of the tooling can be reused.

Solution: We propose enhancing Plutus testing by advancing PSM's features and refactoring its codebase. This will result in a more effective simulation of the Cardano ledger and its most advanced capabilities.
