Decentralized StableCoin (DSC): A Secure and Reliable Endogenously Backed StableCoin

Objective:
Developed a decentralized stablecoin named DSC, backed by Ethereum and Bitcoin, ensuring reliability and security in the crypto market. This stablecoin provides stability by maintaining a peg to USD and incorporates advanced DeFi mechanisms.

Technical Skills and Tools Used:

  • Languages: Solidity
  • Frameworks/Libraries: OpenZeppelin Contracts, Forge-Std
  • Technologies/Tools: Ethereum Blockchain, Chainlink Oracles, Foundry

Functionality Overview:

DeFi and Stablecoins:
Explored decentralized finance (DeFi) and the critical role of stablecoins in providing consistency in the crypto world.

DSCEngine Development:

  • Collateral Management: Implemented features for depositing collateral (Ethereum and Bitcoin) and minting DSC tokens.
  • Health Factor Calculations: Ensured system stability by calculating health factors and implementing collateral redemption.
  • Liquidation Mechanism: Provided a liquidation mechanism with a 10% bonus for liquidating undercollateralized positions, ensuring system solvency.

Dynamic Minting and Burning:
Enabled dynamic minting and burning of DSC to maintain a healthy system, allowing users to mint DSC when their health factor is above the minimum threshold and burn DSC to redeem collateral.

Project Insights and Achievements:

  • Security: Ensured the contract's security by implementing thorough testing and verifiable randomness.
  • Efficiency: Demonstrated efficiency in developing and deploying a stablecoin backed by multiple assets.
  • Interoperability: Achieved seamless interoperability through a helper configuration that enables deployment to mainnet, testnet, and local environments.
  • Streamlined Deployment: Included a Makefile to streamline the deployment process across different networks.

Testing and Deployment:

  • Foundry Testing: Conducted comprehensive testing using Foundry, focusing on fuzz testing and invariant testing to ensure robust contract functionality.
  • Fuzz Testing: Enhanced the robustness of the DSC project by using fuzz testing to randomly generate inputs and test the system against unexpected behaviors.
  • Deployment: Deployed the contract on local and test networks using Foundry and a streamlined Makefile for efficient deployment.

Detailed Breakdown:

Smart Contract Features:

  • Collateral Management: Handled the deposit and redemption of Ethereum and Bitcoin as collateral.
  • Minting and Burning: Implemented dynamic minting and burning of DSC tokens based on health factors.
  • Liquidation Mechanism: Provided a mechanism for liquidating undercollateralized positions with a 10% bonus.

Overall, the Decentralized StableCoin project showcased my ability to integrate complex DeFi mechanisms, providing a stable and reliable cryptocurrency backed by Ethereum and Bitcoin.
