Easy to use merkle generator for token airdrops

Merkle Proof Generator

Given a decimals count for a token and list of airdrop recipients, outputs:

1. A merkle root for use in a Merkle tree verification in smart contracts.
2. A merkle tree for use in a front-end / or merkle proofs per user for Smart contract inputs

Run locally

# Navigate to generator directory, if not already there
cd merkle_generator/

# Install dependencies
npm install

# Edit config.json
vim config.json

# Run script
npm run start

Outputs a merkle.json, in the following format if generator file used:
