0xdavinchee / uniswap-interaction

My first foray into interacting with some of Uniswap's smart contracts, the contracts in here allow naive swaps and flash swaps for arbitrage.

Uniswap Interaction

The Swapper contract allows you to run a simple flash swap arbitrage or just a simple regular swap arbitrage between Uniswap and Sushiswap.

About The Project

Built With

• Solidity
• Hardhat
• TypeScript
• Tenderly
• Uniswap

Getting Started

To get a local copy up and running follow these simple steps.

Installation

1. Clone the repo

   git clone https://github.com/0xdavinchee/uniswap-interaction.git

2. Install NPM packages

   npm install

3. Create a .env file and add the two following values:

• INFURA_API_KEY: You can get this from https://infura.io by signing up for a free account.
• RINKEBY_PRIVATE_KEY (if you want to deploy to testnet).
• ALCHEMY_MAINNET_URL: You can get this from https://alchemyapi.io by signing up for a free account.

Usage

To compile: npx hardhat compile.

To run tests: npx hardhat test.

Run npx hardhat node to start up a local node.

Open up another terminal window and run npx hardhat deploy --network localhost to deploy your project to localhost. You can similarly deploy to other networks like so: npx hardhat deploy --network <NETWORK>.

To execute an arbitrage you would have to open another terminal window and run npx hardhat console --network <NETWORK> and then attach the contract and execute the desired function. This simply executes the arbitrage, but does not actually scope out profitable opportunities nor protect against frontrunning or other adversarial possibilities.
