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.

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.
