MakerDAO – DAI Wormhole

Security Audit

Download Audit Report
Summary

The most critical subjects covered in our audit are functional correctness and access control. Security regarding all the aforementioned subjects is high. General subjects covered were code complexity and gas efficiency. All the aforementioned subjects were of high quality.

In summary, we find that the codebase in its current state provides a high level of security.

It is important to note that security audits are time-boxed and cannot uncover all vulnerabilities. They complement but don’t replace other vital measures to secure a project.

About MakerDAO – DAI Wormhole

The current version of the DAI Wormhole allows fast withdrawal (called “teleport” in the project’s terminology) of DAI from a supported L2 solution onto L1 Ethereum. Using trusted oracles, the DAI can be issued on the receiver domain based on the promise that the amount will eventually be settled through the default bridge.

“The Maker Protocol, also known as the Multi-Collateral Dai (MCD) system, allows users to generate Dai by leveraging collateral assets approved by “Maker Governance.” Maker Governance is the community organized and operated process of managing the various aspects of the Maker Protocol. Dai is a decentralized, unbiased, collateral-backed cryptocurrency soft-pegged to the US Dollar. Resistant to hyperinflation due to its low volatility, Dai offers economic freedom and opportunity to anyone, anywhere.”

It was a pleasure working with ChainSecurity. They maintained clear and direct dialogue with us and we look forward to working with them on future Layer 2 solutions to help us scale and grow the DAI ecosystem.
