This repo contains source contracts and testing suites for the MCAG contracts and the KUMA Protocol. Each corresponding project directory contains documentation in the /docs folder.
The src/kuma-protocol/ folder contains the contracts that comprise the decentralized KUMA protocol. See docs/kuma-protocol/ for KUMA protocol docs.
The src/mcag-contracts/ contains contracts that are managed by the centralized MCAG entity. See docs/mcag-contracts/ for MCAG contracts docs.

This repo contains relevant tests for the two source projects. To run tests:
- Make sure all git submodules are installed using
git submodule update --init - Run
forge test
Make sure forge is at least on the following version: forge 0.2.0 (1a56901 2023-02-15T00:05:20.802314Z)
To skip invariant and fuzz tests run forge test --no-match-path "{*invariant*,*fuzz*}"
Alternatively use the following quickstart command:
rm -Rf 2023-02-kuma || true && git clone https://github.com/code-423n4/2023-02-kuma.git -j8 --recurse-submodules && cd 2023-02-kuma && git submodule update --init && foundryup && forge install && forge build && forge test --gas-report
The root folder contains a slither.config.json file that can be used to run static analysis on the kuma-protocol project. Refer to the foundry docs on how to run Slither
For the following files the invariants should be run with fail_on_revert = true in the foundry.toml:
[invariant]
runs = 256
depth = 256
fail_on_revert = true
Then run the tests with forge test --match-path "*fail.on.revert*"
