MakerDAO Arbitrum Token Bridge Audit

Smart Contract Assessment for MakerDAO

Cantina conducted a focused smart contract assessment of the Arbitrum Token Bridge maintained by MakerDAO, validating recent changes related to escrow transitions and withdrawal limitations. As part of Maker’s cross-chain strategy, this upgrade introduced a mutable escrow design and enforced withdrawal caps per token to enhance bridge control and operational safety. The review ensured that L2-to-L1 redemptions remain fully backed and aligned with protocol expectations, even during administrative updates or spell execution.

This security audits engagement fits within Cantina’s broader approach to Web3 protection, which also includes bug bounty programs and crowdsourced security competitions to reinforce protocol security across evolving deployment architectures.
