Features

• Fetches current prices from Chainlink.
• Fetches current exchange rates from Uniswap V3 pools.
• Calculates the necessary swap amount to adjust Uniswap rates to match Chainlink prices.
• Executes swaps on Uniswap to adjust the rates.
• Validates the adjustment to ensure consistency.

Technologies Used

• Node.js
• TypeScript
• Hardhat
• Ethers.js
• Solidity
• Mocha (for testing)
