Cardano USD (cUSD) is a fully decentralized, ADA-backed stablecoin protocol inspired by Liquity v2. It is designed specifically for the Cardano blockchain, utilizing Cardano's eUTXO model and native staking features to provide a highly secure and efficient stablecoin pegged to the US dollar. Key features include user-driven interest rates (which can also be interest-free), a Stability Pool to absorb liquidations, direct redemptions for ADA, frontend incentives, and minimal governance to ensure decentralization and resilience. Future phases include potential multi-collateral expansion. cUSD aims to become a foundational DeFi asset on Cardano, providing stable, reliable, and transparent dollar-equivalent liquidity for savings, staking, and broader ecosystem integration.

Despite Cardano's robust network and growing DeFi landscape, its stablecoin market remains underdeveloped relative to the platform's potential. Further growth could be catalyzed by introducing next-generation stablecoins with advanced user incentive models:

• Untapped Capital Efficiency: Cardano's large pool of staked ADA represents substantial latent capital. However, the current ecosystem offers limited avenues to efficiently utilize this staked capital within DeFi protocols without sacrificing staking participation.

• Need for A Diverse Stablecoin Solutions: To attract broader user adoption and capture greater market share, Cardano needs stablecoin protocols offering more sophisticated and capital-efficient mechanisms beyond existing models. Specifically, there's a gap for solutions that natively integrate Cardano's yield-bearing assets in novel ways.

Cardano cUSD introduces a yield-bearing stablecoin design, offers benefits across various segments of the Cardano community and provides demonstrable value to the ecosystem as a whole:

For ADA Holders & Stakers:

• Unlock Staked Liquidity: Mint cUSD against staked ADA without unstaking, boosting capital efficiency.
• Flexible Yield Control: Optimize risk/reward by directing staking yield towards debt reduction or separate accrual.
• Enhanced ADA Utility: Increases the incentive to hold and stake ADA.

For Cardano DeFi Users:

• Stable & Efficient Stablecoin: Access a decentralized, Cardano-native USD-pegged stablecoin (cUSD).
• Advanced DeFi Strategies: Enable leveraged staking, self-repaying positions, and new yield opportunities.

For Developers & Protocols:

• Open-Source & Composable: Provides a core, open-source, easily integrable stablecoin primitive.
• Fuel Ecosystem Innovation: Catalyzes synergy and the development of more sophisticated DeFi solutions on Cardano.

Overall Value & ROI for Cardano:

• Drive TVL & Network Activity: Increase Total Value Locked and on-chain transactions/fees.
• Boost Competitiveness: Position Cardano as a leader in innovative stablecoin design, attracting users and capital.

Strengthen Network Effects:

• Enhance the overall utility and value proposition of the Cardano blockchain.

Milestone 1: Project initiation, detailed planning, and completion of technical protocol design documentation.

Milestone 2: Implement Aiken smart contracts for core protocol components (Vault contracts, Stability Pool module, redemption mechanism, oracle integration, and tokenomics model).

Milestone 3: Deploy the initial testnet version of cUSD, including full vault functionalities, Stability Pool integration, oracle feed integration, and an MVP frontend for user interactions.

Milestone 4: Conduct a comprehensive community-driven testnet phase, actively gathering user feedback, performing iterative improvements, and conducting extensive testing.

Milestone 5: Launch the cUSD stablecoin protocol on Cardano mainnet, including DEX listings and integration within the Cardano DeFi ecosystem.

• Protocol Design & Architecture (30,000 ADA): Covers technical specification, economic modeling, and protocol design.

• Smart Contract Development (70,000 ADA): Implementation of Aiken smart contracts for vaults, Stability Pool, redemption logic, and oracle integration.

• Frontend & Infrastructure Development (20,000 ADA): Includes development of an MVP frontend, wallet integration, DEX connectivity, and testnet infrastructure setup.

• Testing & Audits (30,000 ADA): Includes internal testing, a community testnet phase, and an internal security audit.

• Mainnet Launch & Ecosystem Integration (35,000 ADA): Mainnet deployment, DEX listing, initial liquidity provisioning, and marketing/outreach efforts.

• Project Management & Community Support (15,000 ADA): Coordination, documentation, community engagement, and setup of governance-lite mechanisms.

Team Size and Duration Estimates:

• Estimated Team Size: 3 members (1 backend blockchain engineer, 2 smart contract developer)
• Duration: 9-12 months from initial development kickoff to mainnet launch.

Senary Labs possesses extensive experience in blockchain and smart contract development. The team has proven experience in financial engineering (commodities derivatives, risk management) and tech leadership (CTO, Web3 startup) to spearhead this project.

After initial development, Senary Labs will continue to maintain the solution. The code will be open-sourced and maintained on GitHub, allowing for community contributions. Continuous development and improvements will be funded by a dedicated protocol treasury sourced from fees collected from stablecoin minting and redemption activities.

• Reliable and decentralized ADA/USD oracle feed (e.g., Charli3, or other oracle providers).
• Initial liquidity provision.
