WindingTree Market Protocol MVP

This project is an MVP based on the WindingTree Market Protocol, aimed at demonstrating the potential of creating decentralized market solutions.

Tech Stack

• Smart Contracts: Solidity
• Frontend: TypeScript, React, @windingtree/sdk
• Backend: TypeScript, Node.js, tRPC.js, LevelDB, @windingtree/sdk
• Blockchain: Ethereum

Documentation

Additional documentation can be found in the /docs directory.

Repository Setup

First, you need to clone the MVP repository to your local machine or development environment. Open your terminal, and execute the following command:

git clone [email protected]:windingtree/mvp.git ./<your-project-directory>
cd <your-project-directory>

Replace <your-project-directory> with the name of your project directory.

Installing Dependencies

The project uses pnpm for managing dependencies. Install all required dependencies by running:

pnpm install

Ensure you have pnpm installed; if not, follow the installation instructions on the official pnpm website.

Configuring the Local Environment

Copy the example environment files to a new .env files, which you'll need to configure according to your setup:

cp ./packages/server/.env.example ./packages/server/.env
cp ./packages/node/.env.example ./packages/node/.env
cp ./packages/dapp-client/.env.example ./packages/dapp-client/.env
cp ./packages/dapp-supplier/.env.example ./packages/dapp-supplier/.env

Server Configuration

SERVER_PORT=33333
SERVER_ID=""
SERVER_PR_KEY=""
SERVER_PB_KEY=""

Keys generation can be started by the following command:

pnpm gen:key

As result you will get something like this:

SERVER_ID="QmXH7wT21maJx9TrAk3neP45CeD3X5E8QnPLUH6AEYFxRt"
SERVER_PR_KEY="CAISIQKx/mfSakZuFh2x9YJh276O5gI+SX8FLvMH3uC4jRvkkQ=="
SERVER_PB_KEY="CAISIJCpUNDUly32nN2HFDeYNFsqRdOXCUV5K6x9CZnnI4A2"

Important! The private key of the server is a confidential information. Do not publish this key anywhere. Compromising this key will allow evil parties to fake p2p traffic between clients, servers and supplier nodes.

Supplier Node configuration

NODE_TOPIC="<should be common between a node and client>"
NODE_CHAIN="gnosisChiado"
NODE_ENTITY_SIGNER_MNEMONIC="<will be generated during a setup procedure in the Supplier's Dapp>"
NODE_ENTITY_ID="<will be generated during a setup procedure in the Supplier's Dapp>"
NODE_ENTITY_OWNER_ADDRESS="<the supplier's entity owner>"
NODE_SERVER_ADDRESS="<see details below>"
NODE_ENTITY_OFFER_GAP=0.5
NODE_API_CORS="http://localhost:5174"
NODE_RESTART_MAX_COUNT=10
NODE_RESTART_EVERY_TIME_SEC=5
NODE_QUEUE_MAX_RETRIES=20
NODE_QUEUE_RETRIES_DELAY=2000

To get the value of NODE_SERVER_ADDRESS you have to use the following command:

1. For local environment (testing):

pnpm gen:address --env local --id QmXH7wT21maJx9TrAk3neP45CeD3X5E8QnPLUH6AEYFxRt --address 127.0.0.1 --port 33333

You will get something like this:

/ip4/127.0.0.1/tcp/33333/ws/p2p/QmXH7wT21maJx9TrAk3neP45CeD3X5E8QnPLUH6AEYFxRt

2. For production environment

pnpm gen:address --env prod --id QmXH7wT21maJx9TrAk3neP45CeD3X5E8QnPLUH6AEYFxRt --address coordinator.windingtree.com

Address of the server in production looks like:

/dns4/coordinator.windingtree.com/tcp/443/wss/p2p/QmXH7wT21maJx9TrAk3neP45CeD3X5E8QnPLUH6AEYFxRt

Supplier's Dapp configuration

VITE_CHAIN="gnosisChiado"
VITE_WC_PROJECT_ID="<see guidelines of WalletConnect project registration above>"
VITE_SERVER_IP="127.0.0.1" # 46.101.211.99 in production
VITE_SERVER_PORT=33333 # 443 in production
VITE_SERVER_ID="server id generated above"

Client's Dapp configuration

VITE_CHAIN="gnosisChiado"
VITE_NODE_TOPIC="<must be equal to NODE_TOPIC defined above>"
VITE_WC_PROJECT_ID="<see guidelines of WalletConnect project registration above>"
VITE_SERVER_ADDRESS="<must be equal to NODE_SERVER_ADDRESS defined above>"

Building the Project

Compile the project's packages with:

pnpm run build

Smart Contracts

The smart contracts are central to the MVP. Follow the specific setup instructions in the smart contracts repository.

Coordination Server

The coordination server facilitates communication between different parts of the MVP. Launch it with:

pnpm run start:server:dev

Supplier Node and Dapp

The supplier node acts as the backend for suppliers, while the supplier Dapp provides a user interface. Start these with:

pnpm run start:node:dev
pnpm run start:manager

Client Dapp

The client Dapp is the frontend for the end-users. Get it running with:

pnpm run start:client

Linting and Testing

Run linting scripts and tests using the following command:

pnpm run lint
pnpm run test

To run code test coverage use the following command:

pnpm run coverage
