ChainSecurity performed a smart contract audit of MakerDAO’s Optimism DAI bridge smart contracts.

Amazingly, we identified no findings above low severity, which is an extremely rare occurence.

We congratulate the MakerDAO Protocol Engineering Core Unit for their excellent work.

About MakerDAO – Optimism DAI 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 throughout the audit of the Optimism Dai Bridge. 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.
