Merkle Airdrop Smart Contract

This is a smart contract that allows for the distribution of tokens to a list of addresses. The contract is designed to be used with the Merkle Airdrop CLI tool/script.

Setup and Run merkle.js Script

Prerequisites

• Node.js (v14 or later)
• yarn (v1.22 or later)
• Hardhat (for smart contract deployment)

Installation

1. Clone the repository

    git clone https://github.com/your-repo/merkle-airdrop.git
    cd merkle-airdrop

2. Install the dependencies
```bash
    yarn install

Running the Scripts

1. Create a eligible.csv file in the data directory with the list of addresses and their corresponding token amounts.
2. Run the generate script to generate merkle tree data from the eligible.csv file. This will be saved in eligible-packed.json file.

    yarn generate

3. Run the script

    yarn merkle

1. The script will generate a merkle.json file in the data directory. This file contains the Merkle root and the list of addresses and token amounts.
