Ether Cash Flow CLI
Ether Cash Flow is a CLI tool which allows the user to query data for given block numbers on the Ethereum Blockchain and generate meaningful reports based on this data.
Setup
Install NodeJS version 16.15.0 from https://nodejs.org/en/download/ or use NVM (Node Version Manager) to manage different node versions.
Environment Variables
Add your Infura API key to the variable INFURA_API in .env file at the root of this repo.
The ALTERNATE_RPC in .env is set to a free RPC provider from MyEtherWallet so the tool will use it instead of Infura.
To use Infura, remove the ALTERNATE_RPC variable from .env and add INFURA_API key.
Install Dependencies
npm install
Using the tool
Run node index.js at the root of project directory to run the CLI tool.
You could select to search back x number of blocks from latest block on the mainnet or you could select a block range to search between.
Note: The RPC endpoint may be slow in fetching data for large block ranges and the tool may seem unresponsive but be assured that its still working in the background and would output the reports as soon as data fetching is complete.
