Slither

Slither is a static analysis tool for Solidity contracts.

How to run it

pip3 install slither-analyzer
cd origin-dollar/contracts
yarn install
yarn run slither

Updating Slither DB

yarn run slither --triage

Running this command will open an interactive console where you can select the errors/warning that you want to be excluded. Once done, commit and push the updated Slither DB file. Note: make sure you are running the latest version of slither on your local.

Echidna

Echidna is a test fuzzer for Solidity contracts.

The Echnida tests for the OUSD contracts are under contracts/contract/crytic.

How to run it

On MacOS and Linux, download the latest pre-compiled binaries from here. Untar the files in a directory and add the path where the echidna-test binary was extracted to your shell's PATH.

To run the tests:

cd origin-dollar/contracts
yarn run echidna

Note that the tests take about ~30min to run.
