Plu-Stan Expand Cardano Smart Contract Checks

Input Output’s Cardano High Assurance team don deliver wetin di company describe as di first stable release of Plu-Stan. Di development report for September 11, 2026, announce extra checks for common mistakes for decentralized application development, plus one updated Visual Studio Code extension.

Plu-Stan Dey Review Plinth Smart Contracts

Plu-Stan na static analysis tool for Cardano smart contracts wey dem write with Plinth, one Haskell-based language. E build on top di Stan analyzer, and e dey examine code to find patterns wey fit relate to security weakness and higher script execution costs.

Di tool dey point out specific code locations to review and e dey provide recommendations to help developers investigate potential problems before dem deploy their contracts. Im rules cover both how di contract dey behave and how efficient di code be to run am.

Checks Cover Calculations and Cardano Addresses

Di documented rule set cover data handling, address comparisons, transaction validity windows and precision loss for integer calculations.

One example na division before multiplication. Early division fit throway precision because of rounding, and e fit affect fee calculation or any other amount wey di contract calculate. Di documented alternative na to multiply first before you divide afterward.

Another check dey flag comparisons wey only involve di payment credential of one Cardano address. Such comparisons fit miss differences for staking credentials. If contract need complete match, di documentation recommend make dem compare di full address.

Performance checks still dey identify repeated passes over di same lists, wey fit increase script execution costs. These examples come from di documented rule set; di weekly report no specify which individual checks dem add for this release.

VS Code and Cursor Dey Track Findings and Fixes

Di Plu-Stan extension dey organize findings by severity, rule or module. Developers fit inspect explanations, compare problematic code with suggested alternatives and record why dem dismiss one warning.

Coverage dey vary across di rules. Some checks dey detect narrower range of patterns, while other issues no get automated coverage at all. Review wey no show warnings no fit prove say contract secure or replace audit.

Di project release information still dey inconsistent. Even though Input Output report stable release, di repository README still describe Plu-Stan as proof of concept wey never ready for production use.

During active editor review, once you save on-chain module, di analysis go run again automatically and update which findings don fix, new or still unresolved. Dismissed warnings and optional explanations go remain across sessions and teams fit share dem, to preserve review decisions as di contract dey evolve.
