Usage

chainaudit scan contract.sol               # single file
chainaudit scan ./contracts --recursive    # directory
chainaudit scan contracts.zip              # zip archive
chainaudit scan contract.sol --json        # JSON output
chainaudit scan contract.sol --ml-only     # skip simulation
chainaudit --version                       # show version

Exit code 1 if CRITICAL vulnerabilities found — blocks deployments in CI.

What It Detects

EVM (Ethereum, Polygon, BNB Chain...)

Severity	Examples
CRITICAL	Reentrancy, Controlled Delegatecall
HIGH	Unchecked Token Transfer, Weak Randomness, tx.origin Auth
MEDIUM	Timestamp Dependence, Unchecked Send
LOW	Missing Zero Check, Missing Events

L2 / Arbitrum / Optimism — auto-detected

Severity	Examples
CRITICAL	Cross-Chain Replay Attack, Bridge Reentrancy
HIGH	L2 Block Number Assumption, Sequencer Dependence, Address Aliasing
MEDIUM	Force-Include Griefing, Gas Price Assumption

L2 rules activate automatically when the scanner detects Arbitrum/Optimism identifiers (ArbSys, xDomainMessageSender etc.) in the contract source.

---

ML Predictions

Each finding includes an ML-predicted exploitability score trained on the SmartBugs dataset (143 contracts, 88% accuracy).

  "title": "Reentrancy",
  "severity": "CRITICAL",
  "ml_exploitability": "CRITICAL",
