DeFi Stablecoin Protocol

This project implements a decentralized stablecoin protocol with:

• Collateralized stablecoin (DecentralizedStableCoin.sol)
• Core engine for minting, redeeming, and liquidations (DSCEngine.sol)
• Chainlink price feed integration (libraries/PriceFeed.sol)

Project Structure

• contracts/ — Solidity smart contracts
• test/ — Unit, fuzz, and invariant tests
• script/ — Deployment and configuration scripts
• lib/ — Local dependencies (OpenZeppelin, Chainlink, forge-std)

cargo install --path ./crates/forge --profile release --force (imp) '' git init; forge install OpenZeppelin/[email protected]; forge install smartcontractkit/chainlink-brownie-contracts ''

clone the repository

How to Deploy

curl -L https://foundry.paradigm.xyz | iex Set-ExecutionPolicy RemoteSigned -Scope CurrentUser irm get.scoop.sh | iex scoop install foundry

1. Install Foundry dependencies (libraries are in lib/ folder):

   forge install OpenZeppelin/openzeppelin-contracts
   forge install smartcontractkit/chainlink-brownie-contracts

2. Compile contracts:

   forge build

3. Deploy contracts (example using Foundry script):

   forge script script/DeployDSC.s.sol --rpc-url <YOUR_RPC_URL> --private-key <YOUR_PRIVATE_KEY> --broadcast

How to Test

Run all tests using Foundry:

forge test

How to Use

Interact with the protocol using scripts, tests, or a frontend dApp:

• Deposit collateral tokens (WETH, WBTC)
• Mint and burn stablecoins
• Redeem collateral
• Liquidate unhealthy positions

You can use the contract ABIs in artifacts/ to build a frontend (see previous answers for React/Vite/Next.js setup).
