Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch erc20-snapshot@1.0.2 for the project I'm working on.

Here is the diff that solved my problem:

You cant assume tokens are fixed at 18 decimals, fro example many stablecoins are only 6 decimals

balance: balance.div(10 ** parseInt(data.decimals)).toFixed(18)
