Fuel Network Security Scanner

To audit Fuel Network smart contracts written in Sway, you can execute a security scanner workflow that analyzes UTXO handling, predicate logic, and multi-asset transfers to identify vulnerabilities and misconfigurations across FuelVM projects.

A FuelVM audit detects common Sway security issues including UTXO double-spend risks, mis-specified AssetId handling, and storage access pitfalls within contracts, scripts, and predicates.

Yes, you need the forc toolchain, fuels-rs, and access to a local or remote Fuel core node to execute the scanner, load metadata, and perform end-to-end security reviews of your Sway project.

Yes, this Sway scanner performs UTXO-aware audits across contracts, scripts, predicates, and libraries within your Fuel projects to identify risky patterns and security vulnerabilities.

The best way to integrate Sway security reviews is to execute the Fuel audit workflow against your project in development, CI, and security review stages to generate comprehensive security reports.

Auditing UTXO handling in Sway specifically targets FuelVM risks like double-spend vulnerabilities and multi-asset transfer misconfigurations, whereas standard checks often focus on broader reentrancy or overflow issues.
