FluxAggregator Ledger Withdraw script

This script will help you automatically withdraw from FluxAggregator contracts using a Ledger hardware wallet.

The script will query the withdrawable amount for the node address on the list of FluxAggregator contracts provided. If there's a LINK balance, it will prompt to withdraw. A transaction proposal is made to withdraw the full amount from node address to the Ledger's PATH address (admin address).

Note: This script is only meant as a helper. Maintain proper security on your system and always review the transactions before approving.

Configuration

Before starting, a set of environment variables has to be set:

Env var	Description
RPC_URL	An HTTP(s) RPC URL for yourEthereum node. Infura works fine for this.
LEDGER_PATH	Your Ledger path for your account with the address index appended (e.g. m/44'/60'/0'/0/0)
NODE_ADDRESS	The node address in the FluxAggregator contracts. This is the address that writes results to the FA contract.
GAS_PRICE	Gas price in Gwei. Max value is 250. Defaults to 50.

You also need to create a contracts.txt file with a list of FluxAggregator contracts to use. Place one address per line.

Running

Install dependencies with yarn:

yarn

Make sure your Ledger HW wallet is connected, unlocked and the Ethereum application is started.

Always verify the transaction params before approving the transaction!

Simply run the script with Node:

node ./index.js

Note: If you are getting errors about not being able to connect to the device, try running with sudo: sudo -E node ./index.js

The script will now check the withdrawable amounts in the FluxAggregator contracts, and prompt you to withdraw!
