Anza contributed the following description of BPF Stake Program:

The BPF Stake Program is a port of the existing Native Stake Program to run as a true onchain program instead of a component of the validator client.

Zellic conducted a security assessment for Anza from February 21th to March 7th, 2025. During this engagement, Zellic reviewed BPF Stake Program's code for security vulnerabilities, design issues, and general weaknesses in security posture.
