How the Trap Works

1. Data Collection:

   • The trap contract fetches the price of UNI tokens from various reliable sources, such as Chainlink, to get accurate price feeds.

2. Validation:

   • The fetched price data is compared to detect any significant discrepancies. If a substantial difference is identified, it suggests potential price manipulation.

3. Response:

   • Upon detecting a price discrepancy, the trap contract triggers measures to halt or mitigate the exploit, protecting the protocol from further damage.

Summary

The Compound UNI Exploit Trap provides a robust mechanism to detect and mitigate exploits targeting the Compound protocol. By monitoring price feeds from multiple sources and comparing them, the trap contract can identify potential manipulation attempts and take immediate action to protect the protocol.
