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.
ZKsync Security
ZKsync Smart Contract Audit Services
ResearchZero provides ZKsync smart contract audits, blockchain security reviews, protocol risk analysis, and infrastructure security for teams building on ZKsync. ZKsync supports scalable Ethereum applications with native account abstraction, zk rollup settlement, and evolving developer tooling.
Supported Environment
ZKsync blockchain security review
ZKsync reviews account for EVM-like code, EraVM differences, account abstraction behavior, paymaster logic, bridge flows, and contract deployment patterns that differ from Ethereum mainnet.
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.
ZKsync risks we review
- Account abstraction logic
- Paymaster abuse paths
- EraVM compatibility assumptions
- Bridge and withdrawal flows
- Deployment and factory controls
Programming Environment
ZKsync smart contract languages and tooling
ZKsync supports EVM-oriented development with EraVM differences, native account abstraction, paymasters, custom deployment behavior, and rollup bridge flows.
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.

ZKsync FAQ
Security review questions for ZKsync
Does ResearchZero support ZKsync?
Yes. ResearchZero supports ZKsync security reviews for smart contracts, protocol logic, infrastructure, and institutional financial applications.
What code and systems can be reviewed?
We review Solidity, EraVM, and account abstraction patterns, protocol architecture, privileged operations, deployment controls, integrations, custody flows, and chain-specific assumptions.
When should a ZKsync 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.
