A full smart contract security workflow involves running Slither scans, checking upgradeability and ERC conformance, generating security diagrams, documenting properties for fuzzing, and performing a manual review. This structured approach identifies vulnerabilities and ensures standards compliance.

Slither scans Solidity codebases to identify static analysis vulnerabilities and triage findings. It detects issues like unused variables, uninitialized storage, and reentrancy paths, serving as the foundational automated security check before deeper manual review.

Documenting smart contract security properties for formal verification involves defining invariants and expected behaviors of the contract. Generating visual security diagrams and detailed property documentation provides the necessary specifications for fuzzing and formal verification tools.

The secure development workflow applies to various Solidity projects, but it specifically includes checks for upgradeability patterns. For non-upgradeable contracts, you can still use the workflow for Slither scans, ERC conformance checks, and manual security review, skipping upgrade-specific validations.

The best way to visualize security structures in smart contracts is by generating dedicated security diagrams. These diagrams map out contract interactions, access controls, and data flows, helping developers understand the architecture and identify potential attack vectors.

A manual security review is necessary because automated tools like Slither cannot catch all logic flaws, business logic vulnerabilities, or complex systemic risks. A structured manual review checklist catches issues automated tools miss, ensuring comprehensive contract security.
