I was inspired to do this because, when disabling the slither check for the delegatecall when calling the swap executor, I realized it's not clear from the same contract that we have already checked for contract code existence when setting the executor. This made me feel uneasy, as this contract can then not stand alone and must rely on the higher level contract to safely check for code existence, otherwise the delegatecall is unsafe. Keeping this logic in a separate contract seems error-prone to me, as we may remove the check for code existence without immediately realizing the implications of doing so. For this reason I have organized it as follows: - Logic/tests relating to proper roles/access control in the main TychoRouter. - Lower-level logic/tests that checks contract validity before setting the executor in the SwapExecutionDispatcher
Tycho Execution
TODO: add banner
Tycho Execution makes it easy to trade on different DEXs by handling the complex encoding for you. Instead of creating custom code for each DEX, you get a simple, ready-to-use tool that generates the necessary data to execute trades. It’s designed to be safe, straightforward, and quick to set up, so anyone can start trading without extra effort.
Contract Analysis
We use 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 .
