Static Analysis

Static analysis examines a smart contract's source code or bytecode without running it, looking for known-risky patterns, unsafe constructs, and code-quality issues. It is fast, deterministic, and repeatable, which makes it ideal for continuous checks in CI.

What It Catches

• Known vulnerability patterns (e.g. unchecked external calls, tx.origin auth, unsafe delegatecall).
• Code-quality and best-practice violations.
• Suspicious control-flow and data-flow paths.

Because it doesn't execute the contract, static analysis is quick but can produce false positives and cannot confirm exploitability on its own.

Static vs Dynamic

Static analysis reasons about all code paths at once; dynamic techniques like fuzzing and symbolic execution explore behavior by executing the contract with many inputs. The strongest reviews combine both. Slither is the most widely used Solidity static analyzer.

Frequently Asked Questions

Q: Is static analysis enough to secure a contract?

A: No. It quickly surfaces known patterns but produces false positives and misses logic bugs. Combine it with fuzzing, symbolic execution, and expert manual review.

Q: Where does static analysis fit in a workflow?

A: It is well suited to run automatically on every change in CI, giving fast feedback before deeper, slower analysis and manual audit.
