# Compound cToken Event Monitor

## Description

This agent monitors Compound Finance cToken contracts for common market events like Mint, Borrow,
etc.  Monitored events are specified in the agent-config.json file, with associated Finding types
and severities for each one.

This agent also checks the Compound Finance Comptroller contract on every block to compare the most

added, the new cToken address(es) are placed into the Array for monitoring in that block and all
subsequent blocks.
