Project Description

The MEV Protection System is a DeFi tool that makes life harder for MEV bots by making swap fees unpredictable. Think of it as a dynamic bouncer for your trades - every time someone makes a swap, it rolls a random dice (using Pyth Network) and checks current market prices (via Chronicle) to set a unique fee. These fees go to a locked wallet that bots can't interact with.

By making it impossible to know the exact cost upfront, we prevent those annoying sandwich attacks where bots squeeze extra profit from your trades. It's like changing the locks every time someone opens the door - the bots never know what they're going to get!

The best part? If you're just a regular trader, you can swap as usual. The system only makes life difficult for those trying to game the system.

How it's Made

Our MEV Protection System is built on several cutting-edge blockchain technologies. The core logic runs on Scroll, a promising new Layer 2 where we've been exploring and testing our solution. We're using Uniswap v4's new hooks feature to catch trades as they happen, Chronicle's data feeds to get real market prices, and Pyth Network for generating random numbers we can trust.

The frontend is built with React and Next.js to keep things smooth and fast, with Tailwind making it look clean. We've got MetaMask integration to make it easy to connect and trade, and everything's tied together with ethers.js to talk to the blockchain.

It's like building a high-tech security system - each piece plays its part in making trades safer, with Scroll giving us the speed and low costs we need to make it practical.
