Proof DEX

Official Repository for the Proof Decentralized Exchange

Architecture

The proof decentralized exchange is a hybrid decentralized exchange that aims at bringing together the ease of use of centralized exchanges along with the security and privacy features of decentralized exchanges. Orders are matched through the proof orderbook. After orders are matched, the decentralized exchange operator has the sole ability to perform a transaction to the smart contract. This provides for the best UX as the exchange operator is the only party having to interact directly with the blockchain. Exchange users simply sign orders which are broadcasted to the orderbook. This enables users to cancel their orders without having to perform a blockchain transaction and pay the associated gas fees.

Development and Testing Environment Setup

Requirements :

• OSX or Linux (Windows setup is likely possible but not covered in this guide)
• Node (version 8.9.4 recommended)
• Solidity Compiler (version 0.4.18 or other)
• Ganache-cli (v6.0.3 or higher)

Testing Environment Setup :

• Clone the repository and install dependencies

git clone https://github.com/ProofSuite/proof-dex.git
cd prood-dex
npm install

• Install the latest version of truffle (Truffle v4.0.6)

npm install -g truffle

• Compile contracts

truffle compile

• Initialize testrpc (or geth)

./start_rpc.sh

• Migrate contracts to chosen network

truffle migrate --network development

• Make sure you are using the latest version of node

nvm install 8.9.4
nvm use 8.9.4

• Fill in truffle.js and deploy_contracts.js with appropriate wallet addresses. Unlock the corresponding addresses.

• Verify all tests are passing.

You need to re-migrate all contracts before running the test suite

truffle migrate --reset && truffle test

• You can interact with the contracts via the console

truffle console

• You can watch for changes on the fileystem with:

npm run watch

• Lint

npm run lint
