[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

This proposal will integrate Midnight blockchain functionality into the existing Lucem Cardano wallet, creating a privacy-enabled multi-chain wallet that supports both Cardano and Midnight networks. As a community-driven, open-source alternative to existing solutions, Lucem will provide users with more choice in decentralized wallet options for accessing Midnight's privacy-preserving capabilities. Midnight is a privacy-focused blockchain that enables confidential transactions and smart contracts using zero-knowledge proofs, providing users with programmable privacy capabilities.

Our plan is to design, develop, and release Midnight integration in multiple phases to ensure stability and gather user feedback at each stage. This approach minimizes deployment risks and maintains backward compatibility while gradually introducing new privacy features.

KEY DELIVERABLES

• Midnight Network Support: Add Midnight as a supported network alongside Cardano mainnet/testnet, with seamless network switching and network-specific state management. Users can switch between Cardano and Midnight networks without losing context or wallet session.

• Confidential Transaction Support: Enable users to send and receive confidential transactions on Midnight using zero-knowledge proofs. Integrate Midnight's transaction building and signing libraries, create transaction construction UI for confidential transactions, and implement transaction submission to Midnight network.

• Midnight Asset Management: Support for Midnight native tokens (DUST for transaction fees) and custom tokens minted on Midnight. Note: NIGHT tokens are Cardano Native Tokens (CNTs) already supported in Lucem; Midnight integration enables using NIGHT on the Midnight network for privacy-preserving transactions. Extend existing asset management system to handle Midnight-specific asset metadata and create unified asset view showing both Cardano and Midnight assets in one dashboard.

• Cross-Chain Asset Viewing: Display balances from both Cardano and Midnight in a unified dashboard, extending the existing cross-chain viewing architecture (similar to Milkomeda integration). Implement network-specific balance caching and seamless network switching.

• Privacy Settings UI: User interface controls for managing transaction privacy preferences, enabling selective disclosure as emphasized in Midnight's architecture. Users can select privacy levels (public, semi-private, fully private), choose transaction types (standard vs. confidential), and view privacy indicators in transaction history, ensuring full user control over data privacy.

• Midnight dApp Integration: Support for connecting to Midnight-based decentralized applications following the React Wallet Connect guide (https://docs.midnight.network/how-to/react-wallet-connect). Extend CIP-30 API to support Midnight network, add Midnight-specific wallet injection (window.midnight or similar), and support for Midnight smart contract interactions using Midnight.js library.

• Performance and Stability Improvements: Optimize blockchain sync times with better caching and incremental updates, reduce transaction failure rates through improved fee estimation and retry logic, and ensure resilience to API outages by supporting multiple data providers.

• User Interface and UX Refinement: Modernize UI with improved accessibility, clear network indicators, privacy indicators, and streamlined transaction flow for both Cardano and Midnight operations.
