Facet Protocol contributed the following description of Facet Bridge:

Facet Protocol is an EVM-compatible rollup that offers a novel approach to scaling Ethereum without introducing new dependencies or trust assumptions. As a fork of Optimism’s OP Stack, the framework behind many of the largest Layer 2 rollups, Facet differentiates itself by eliminating all sources of centralization and privilege, resulting in the first rollup that preserves Ethereum’s liveness, censorship resistance, and credible neutrality.

Facet Bridge, the focus of this audit, is a trust-minimized bridge built as a fork of OP Bridge. Given the Facet Protocol itself does not force the use of any enshrined (built-in) contracts, Facet Bridge is a third-party application developed to demonstrate how trust-minimized architecture can operate on Facet.

Zellic conducted a security assessment for Facet Protocol from October 17th to October 23rd, 2024. During this engagement, Zellic reviewed Facet Bridge's code for security vulnerabilities, design issues, and general weaknesses in security posture.
