Optimism Bedrock
June 2023
Sigma Prime reviewed Optimism Bedrock components across L2 system logic, untrusted input handling, serialization boundaries, and implementation safety. The engagement is a reference point for rollup teams looking at how malformed data, type handling, and boundary checks affect protocol correctness.
Executive summary
Sigma Prime assessed Optimism Bedrock components with emphasis on handling untrusted inputs, serialization boundaries, and implementation safety. The engagement identified critical/high issues as well as medium/low weaknesses that could affect robustness under adversarial conditions. The remediation guidance improves protocol safety by tightening validation and reducing exploitability across core paths.
