What is Slither?

An open-source Python framework that scans smart contract source code for security issues using built-in detectors, generates visual contract analysis reports, and provides an extensible API for writing custom vulnerability checks. Enables developers to catch bugs before deployment and better understand contract behavior.

The Vioscale score: one lens on the evidence

Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Slither, not the verdict.
