Smart contract audits
Manual review of code paths that move assets, authorize operations, settle balances, mint or burn tokens, route messages, or modify protocol state.
Optimism Security
Optimism Smart Contract Audit Services
ResearchZero provides Optimism smart contract audits, blockchain security reviews, protocol risk analysis, and infrastructure security for teams building on Optimism. Optimism and OP Mainnet support cost-efficient DeFi, governance, payment, and appchain-adjacent ecosystems across the Superchain.
Supported Environment
Optimism blockchain security review
Optimism security work covers EVM logic, OP Stack deployment behavior, cross-domain messaging, withdrawal mechanics, governance controls, and Superchain integrations.
ResearchZero reviews the chain-specific execution model and the financial logic built on top of it. The goal is to identify exploitable code paths before production value, user assets, governance authority, or institutional operations depend on them.
Engagements can include pre-launch audits, targeted reviews of remediations, protocol architecture review, cross-chain integration assessment, and post-audit support for engineering teams preparing a production deployment.
Optimism risks we review
- Cross-domain messenger usage
- Withdrawal and bridge assumptions
- Superchain integration risk
- Sequencer availability
- Governance and upgrade controls
Programming Environment
Optimism smart contract languages and tooling
Optimism uses OP Stack EVM execution with cross-domain messaging, L1/L2 withdrawal flows, and Superchain-oriented deployment patterns.
ResearchZero reviews both the source-level implementation and the execution environment around it: compiler behavior, deployment artifacts, transaction construction, permissions, upgrade paths, and the runtime assumptions that can change how production code behaves.

Optimism FAQ
Security review questions for Optimism
Does ResearchZero support Optimism?
Yes. ResearchZero supports Optimism security reviews for smart contracts, protocol logic, infrastructure, and institutional financial applications.
What code and systems can be reviewed?
We review Solidity and EVM-compatible contracts, protocol architecture, privileged operations, deployment controls, integrations, custody flows, and chain-specific assumptions.
When should a Optimism audit happen?
Schedule review before mainnet deployment, major upgrades, new asset support, bridge integrations, custody changes, or any release that changes how value moves through the system.
