Mantle L2 Rollup

July 2023

Bounty Meridian reviewed Mantle L2 rollup architecture and implementation assumptions across validator and sequencer behavior, fraud-related paths, and implementation safety. The case study is relevant for rollup teams scoping audits across contracts, protocol logic, and operator assumptions.

Engagement snapshot

Bounty Meridian reviewed Mantle’s L2 rollup architecture and build-out assumptions around validator/sequencer behavior and fraud-related pathways. The report flagged one high-severity issue and multiple high-severity findings, alongside /low hardening recommendations. The resulting remediation plan strengthens pre-launch security posture and tightens reliability of core rollup mechanics.
