🚀 Decentralized Stablecoin (DSC) - Your Gateway to Stability!

🌟 Overview

The Decentralized Stablecoin (DSC) is a next-gen, overcollateralized stablecoin inspired by DAI but with zero governance fees!

Powered by ETH & BTC collateral, it ensures price stability using an advanced minting and burning mechanism.

The system is secured by Chainlink oracles and includes fail-safe liquidation protections to keep everything running smoothly. 💪

🔥 Features

• Overcollateralized Stability: Backed by ETH & BTC for a robust peg.
• Smart Minting & Burning: Fully algorithmic & trustless.
• Rock-Solid Price Feeds: Chainlink-powered oracles ensure reliable data.
• Failsafe Mechanisms: No risky trades—only secure transactions!
• Bulletproof Testing: Unit tests, fuzz testing, and mocks for complete reliability.

🏦 How to Use DSC

💰 Minting DSC (Get Your Stablecoins!)

• Deposit WETH or WBTC as collateral.
• Ensure you meet the overcollateralization ratio.
• Call depositCollateralAndMintDsc() in DSCEngine.

🔄 Redeeming Collateral (Get Back Your Assets!)

• Burn DSC equal to the collateral value.
• Call redeemCollateralForDsc() in DSCEngine.

⚠️ Liquidation Protection

• If a user’s health factor falls below 1.0, liquidation kicks in to protect the system.
