Adrastia contributed the following description of Adrastia PID Controller:

Adrastia is a blockchain data and automation platform that increases the economic and technical security of DeFi platforms through robust oracles and data controllers.

Adrastia’s PID controller system automatically optimizes the output to minimize the input error. The primary use case is managing interest rates — input is a pool utilization rate, the error is the difference between the utilization rate and the target, and the output is the interest rate. It updates upon a fixed period and reads from Adrastia’s Time-Weighted Value and Error Oracles whose averaging period matches the controller period.

Zellic conducted a security assessment for Adrastia from April 29th to May 3rd, 2024. During this engagement, Zellic reviewed Adrastia PID Controller's code for security vulnerabilities, design issues, and general weaknesses in security posture.
