Supported Environment

Linea blockchain security review

Linea reviews cover EVM contract logic, zkEVM deployment assumptions, canonical bridge dependencies, finality expectations, and integration risk across Ethereum and L2 liquidity.

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.

Linea risks we review

  • zkEVM deployment assumptions
  • Canonical bridge dependency
  • L1/L2 message handling
  • Finality and withdrawal behavior
  • Oracle and liquidity integration
Programming Environment

Linea smart contract languages and tooling

Linea is an EVM-compatible zk-rollup, so Solidity systems should be reviewed for normal EVM issues plus zkEVM deployment, bridge, and finality assumptions.

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.

Audit Coverage

Security services for Linea teams

Focused review for financial protocols, infrastructure providers, fintech teams, custodians, asset issuers, and DeFi applications building in the Linea ecosystem.

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.

Protocol risk review

Adversarial analysis of economic assumptions, liquidity dependencies, oracle design, governance authority, upgrade controls, and operational failure modes.

Infrastructure assessment

Security review for bridges, relayers, indexers, signing flows, custody integrations, monitoring systems, and deployment processes around Linea applications.

Linea FAQ

Security review questions for Linea

Does ResearchZero support Linea?

Yes. ResearchZero supports Linea 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 Linea 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.
