Multi-mortgage Dai security audit results announced

Runtime Verification, Trail of Bits, PeckShield, and Certora have completed security audits for multi-mortgage Dai. The audit successfully found some vulnerabilities in the system, including high severity and major seriousness. The Maker development team has evaluated and resolved these vulnerabilities and will continue to work with the audit firm to ensure that the multi-mortgage Dai is fully resolved before the release. Next, the Maker development team will focus on the following aspects: 1. Multi-mortgage Dai's phased deployment; 2. Instant access module scalability, including components that have restricted changes to the Dai credit system directly, without DS-Chief All unanimous authorization; 3. Emergency shutdown module and redeployed test run.
