eth-mempool-whale-watcher

listen for large ETH movements in the mempool.

This task will monitor pending transactions and report all movements of ETH over a given threshold. I built this as a way to play around with geth but it may be useful as a tool for certain MEV strategies or for analytics.

Usage

docker

create a .env file in the root directory and set NODE_URL to a websocket enabed geth node url. (example: wss://eth-mainnet.alchemyapi.io/)

Then run

docker-compose up

local

NODE_URL=<websocket geth node url> go run main.go

Setting the threshold

the env var MONITOR_ETH_THRESHOLD (denominated in ETH) is checked first and used for the reporting threshold if possible. If absent a default value is used.
