Transaction Bot Monitoring

What is Transaction Bot Monitoring?

Transaction Bot Monitoring is primarily used for on-chain transaction monitoring.

Typical Scenarios of Transaction Bot Monitoring

1. Monitoring transactions from a specific sender

2. Monitoring transactions to a specific recipient

3. Sending alerts when ETH is greater than or less than a target threshold

4. Monitoring transactions with a specific methodId
