New Fuzzer!
The Recon Extension now supports the Recon Fuzzer, a 10x faster Rust rewrite of Echidna.

Features:

• Show ETA when fuzzing

  

• You can now toggle a property to be ignored, ignored properties do not show in the report and CryticToFoundry

  

• One click Canary generation

  

• Code now uses Start and Stop Prank

• Echidna’s Symbolic mode is now enabled by default

Bug Fixes:

• Contracts are now separated by path, therefore contracts with the same name will show

• The Extension will now properly generate a Report and Repro for Optimization Properties

Nice to have:

• Warns if you echidna or medusa is not installed

• Use git submodules for the Recon Dependencies

• Threads are automatically detected to set recommended default Workers
