Requirements

• Python 3.6+
• installed Python dependencies (pip install -r requirements.txt)

Usage

python3 main.py

The script:

• retrieves balance data from an ETH2 beacon node, using the parameters specified in config.yml . If you're running a Prysm beacon node, make sure to set the PRYSM_API config option to True. If you're running a Nimbus beacon node, make sure to set the NIMBUS_API config option to True.
• pulls corresponding price data from CoinGecko
• combines and writes these into a CSV file called rewards_{VALIDATOR_INDEX}_{ETH2_ADDRESS}.csv

Tested with

• Lighthouse v1.1.0
• Prysm v1.2.1 (set PRYSM_API to True in the config file)
• Teku v21.1.1
  • Teku prunes chain data by default - if you're getting 404 errors, make sure you are running Teku in archive mode to be able to retrieve balances for finalized epochs (--data-storage-mode=archive)
• Nimbus v1.0.7 (set NIMBUS_API to True in the config file)
