Network audit coverage

zkSync Smart Contract Audit

Security review for zkSync projects, including account abstraction systems, DeFi protocols, wallets, bridges, and chain-specific attack paths.

zkSync audit focus

A zkSync smart contract audit should review code behavior and the execution model that surrounds it. CTDSEC checks how the protocol manages assets, state transitions, authorities, external calls, upgrades, and network-specific assumptions.

The review starts with the frozen commit and then follows the paths that can affect user funds, protocol solvency, governance execution, bridge safety, and emergency controls.

Network-Specific Security Considerations

Important zkSync review points that generic checklists often miss.

  • native account abstraction and paymaster behavior
  • bootloader and system-contract assumptions
  • L1-L2 messaging and bridge flows
  • compiler and EVM compatibility differences

Typical Audit Targets

Common zkSync systems that need manual security review.

  • account abstraction systems
  • DeFi protocols
  • wallets
  • bridges
  • token contracts

Smart Contract Audit FAQ

Short answers for teams preparing an audit scope.

What makes a zkSync audit different?

zkSync uses zkEVM with native account abstraction, so the audit needs to account for native account abstraction and paymaster behavior and bootloader and system-contract assumptions.

Which zkSync contracts can CTDSEC review?

CTDSEC can review account abstraction systems, DeFi protocols, wallets, bridges, token contracts when the codebase, documentation, tests, and deployment assumptions are available.

Does CTDSEC only audit zkSync?

No. CTDSEC audits smart contracts across many ecosystems and keeps chain-specific pages connected to the broader smart contract audit process.

Request a zkSync smart contract audit

Send the repository, target network, language, documentation, and timeline so CTDSEC can scope the review accurately.
