Question 1

How do I reduce false positives when using Mythril?

Accepted Answer

Adjust the transaction limit with -t flag and set execution timeouts to control path exploration. Manually review reported issues against the SWC registry for context-specific validation.

Question 2

Mythril vs Slither: which is better for smart contract security?

Accepted Answer

Mythril uses symbolic execution on bytecode for deep path analysis, while Slither analyzes Solidity source code statically for faster results. Choose Mythril for comprehensive vulnerability detection and Slither for quicker, incremental checks during development.

Question 3

Can Mythril analyze contracts on Polygon or BSC?

Accepted Answer

Yes, since Polygon and Binance Smart Chain are EVM-compatible, Mythril can analyze contracts on these networks by providing the contract address or bytecode, similar to Ethereum.

Question 4

How to integrate Mythril into a GitHub Actions workflow?

Accepted Answer

Use the Docker image or pip installation in a GitHub Actions YAML file, then run myth analyze commands. The pre-commit hook option also simplifies integration for code commit stages.

Question 5

What common vulnerabilities does Mythril miss?

Accepted Answer

Mythril might miss logic errors or business logic flaws not covered by symbolic execution patterns, and it relies on predefined vulnerability detectors, so novel attack vectors may go undetected.

Question 6

Is Mythril suitable for auditing large, complex DeFi contracts?

Accepted Answer

Yes, but expect longer analysis times and potential resource constraints; use transaction limits and timeouts to manage performance, and combine with other tools for a thorough audit.
