This is a simple on-chain OTC market for MKR. You can either pick an order from the order book (in which case delivery will happen instantly), or submit a new order yourself.

Maker Market is undergoing alpha testing: Proceed at your own risk, and use only small amounts of ETH and MKR.

Overview

This dapp uses Meteor as frontend; the contract side can be tested and deployed using dapple.

Usage (for Users)

Ensure you have a locally running ethereum node.

Installation (for Developers)

Requirements:

• geth brew install ethereum (or apt-get for ubuntu)
• solidity https://solidity.readthedocs.org/en/latest/installing-solidity.html
• meteor curl https://install.meteor.com/ | sh
• Global dapple, npm install -g dapple meteor-build-client

Clone and install:

git clone https://github.com/MakerDAO/maker-market
cd maker-market
git submodule update --init --recursive
npm install
npm run build

Usage (for Developers)

You need to build the JS wrappers for the Dapple contracts:

npm run build

To run the frontend, start meteor:

cd frontend && meteor

If you got the error message File not found: build/meteor.js, then you forgot to run the build step from above.

You can access the user interface on http://localhost:3000/

To deploy the frontend to Github Pages:

gulp deploy
