Tech Stack

• Node
• Ethers (Blockchain Interaction)
• Truffle (Development Framework)
• Ganache-cli (For Local Blockchain)
• Alchemy (For forking the Ethereum mainnet)

Requirements For Initial Setup

• Install NodeJS, I recommend using node version 16.5.0 to avoid any potential dependency issues
• Install Truffle, In your terminal, you can check to see if you have truffle by running truffle --version. To install truffle run npm i -g truffle.
• Install Ganache-cli. To see if you have ganache-cli installed, in your command line type ganache-cli --version. To install, in your command line type npm install ganache-cli --global

Setting Up

1. Clone/Download the Repository

2. Install Dependencies:

$ npm install

3. Start Ganache CLI

You will need to fork the Ethereum Mainnet onto your local machine. The command below will do just this, while unlocking the account address which you provide.

• Please note, whichever address you choose to unlock, must be cooresponding to the UNLOCKED_ACCOUNT variable in 1inch_Swap.js

In your terminal run:

ganache-cli -f wss://eth-mainnet.alchemyapi.io/v2/<Your-App-Key> -u <UNLOCKED_ACCOUNT_ADDRESS> -p 7545

4. Start the Script to See the Swap in Action

The script will run using UNLOCKED_ACCOUNT. Must match whichever account you chose to unlock when forking.

$ truffle exec ./scripts/1inch_Swap.js`
