+# Contract Analysis
+
+We use [Slither](https://github.com/crytic/slither) to detect any potential vulnerabilities in our contracts.
+
+To run locally, simply install Slither in your conda env and run it inside the foundry directory.
+
+```
+conda create --name tycho-execution python=3.10
+conda activate tycho-execution
+
+python3 -m pip install slither-analyzer`
+cd foundry
+slither .
