AztecProtocol / aztec-v1-loan-dapp

A kitchen sink example of how to build private dApps using AZTEC

loan-dapp-starter-kit

This dapp is accompanied by a series of Medium articles to help developers get started with AZTEC.

DEMO: https://youtu.be/LRt1SKB2514

The code base is split into 3 main folders.

1. client (The frontend react code that interfaces with web3 and graph-ql)
2. contracts (The solidity contracts deployed to ganache that interact with AZTEC)
3. graph (The graph-node mappings that index the local blockchain)

This repo requires the following minimum versions installed in the developer enviroment:

Truffle v5.0.12 (core: 5.0.12)

Solidity - 0.5.4 (solc-js)

Node v11.13.0

Web3.js v1.0.0-beta.37

Yarn - 1.15

Getting started:

1. git clone [e-mail]:AztecProtocol/loan-dapp-starter-kit.git

2. cd loan-dapp-starter-kit

3. cp .env.test .env

This copies the local file to a local .env file that ganache will use to deterministically create test accounts to make local development easier.

4. yarn install

5. cd client && yarn install

6. cd .. && yarn start

The start script will do the following:

• Start ganache, importing any accounts from the .env file
• Compile and migrate both the dApp contracts and AZTEC and deploy the contracts the the local blockchain
• Start a docker container that runs the graph-node
• Build the graph-node mappings and deploy them to the graph-node
• Copy the truffle build artefacts to the client for interaction with the contracts (ABIs)

7. In a new terminal window yarn client

This command will run the create-react-app and host the client at localhost:3000

Navigate to http://localhost:3000 and click the restore account button.

Ganache has been started with 3 deterministic development accounts, each funded with 1000 ETH (Wahoo). You can restore the first account by using the seed phrase office shallow practice favorite diary review floor quote faith initial foot squeeze.
