🇳🇱 cairo-dutch

A Dutch Auction written in Cairo for StarkNet. Ported after studying a reference implementation from solidity-by-example.

A Gradual Dutch Auction has also been added for Starknet. It refers to a new type of Dutch Auction created by Paradigm Research

Allows configurable duration, discount rate, & ERC20 token type accepted as payment.

⚠️ WARNING: This is not intended for production use. The code has barely been tested, let alone audited.

Development

source venv/bin/activate
python -m pip install cairo-nile
nile install

Needs more tests, but basic coverage can be run using the following:

(venv) ~/dev/eth/starknet/cairo-dutch$ make test

VSCode DevContainers

This was required (for me, at least) to run on an M1 mac instead of my usual ubuntu box. Using the setup found in tarrencev/starknet-scaffold I was able to get it working in VSCode.

If you are using VSCode, we provide a development container with all required dependencies. When opening VS Code, it should ask you to re-open the project in a container, if it finds the .devcontainer folder. If not, you can open the Command Palette (cmd + shift + p), and run “Remote-Containers: Reopen in Container”.

In the Cairo LS shell that gets spawned, run poetry install. Then, a poetry run pytest should function as if we were on the typical linux setup.
