MooMaker Offchain Services

This repository contains the offchain services that MooMaker uses to connect the COW solver with marketmakers via the MooMaker auction system.

The offchain services consists of 2 parts:

• REST API with a single POST endpoint, which the solver accesses to publish a new COW batch auction.
• A websocket which:
  • Publishes the COW batch auction to the market makers.
  • Receives bids from market makers.
  • Informs market makers when a bid has been accepted.

Usage

Running main.py will start the websocket and REST API on 2 different servers.

• REST API: http://127.0.0.1:5000/cow
• websocket: ws://localhost:8765/

Use the files in the examples directory to test the flow as follows:

1. Open the websocket connection
2. Send the single_order_instance1_input.json in the body (as json) with a POST request to the REST endpoint. A copy of this file should now appear on the websocket.
3. Within 5 seconds, send the content of market_maker-response.json via the websocket.
4. The auction is closed and the winning bid is announced [NOT IMPLEMENTED YET]
