# 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= 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.
