GeoNFT and Spatial Data Registry Proof-of-Concept

Monorepo with two packages:

• hardhat-ts: a hardhat typescript project
  • runs and deploys the NFT contracts to a local node
  • deploys contract to Alfajores testnet
  • deploys contract to Celo mainnet
• dapp: a React, Redux web application
  • allows anyone to mint a GeoNFT
  • IPFS for metadata
  • adds a Ceramic document

TODO

• dapp
  • Add wallet mock to expand testing in Jest

Requirements

Yarn

Install

git clone https://github.com/AstralProtocol/geonft-registry-poc.git
cd geonft-registry-poc
yarn install

Setup .env file for dapp

Create an Infura Account and an Infura project with IPFS Service, copy packages/dapp/.env.sample to packages/dapp/.env and fill in the following fields:

REACT_APP_PROJECT_ID=

REACT_APP_PROJECT_SECRET=

Setup Metamask

To run locally, create a new profile in Chrome and open the Metamask plugin.

Import the test seed phrase: test test test test test test test test test test test junk

Under Networks click Show/hide test networks

Open Metamask Settings, Networks, and select Localhost 8545. Set chainId to 31337

Select Localhost 8545 network.

Notice: when running a Localhost node, you may receive this error: Nonce too high. Expected nonce to be 1 but got N. Note that transactions can't be queued when automining. As a fix, go to Settings, Advanced, and click Reset Account.

Run

Hardhat Local Node

Open a terminal and run yarn hardhat:localnode

Run dapp

Open packages/dapp/webpack.config.js and update devServer...host with your local IP Address.

Open a second terminal and run yarn dapp:start

Open your Chrome profile with test Metamask instance and go to https://YOURIPADDRESS:8080/

Wallet

1. Select Metamask and connect with the localhost node.
2. Select WalletConnect and scan the QR Code with your Alfajores wallet.

Available Scripts

In the project directory, you can run:

dapp

yarn dapp:test

Runs the React test watcher in an interactive mode. By default, runs tests related to files changed since the last commit.

Read more about testing React.

yarn dapp:webpack

Builds the dapp for production to the build folder. It correctly bundles React in production mode and optimizes the build for the best performance.

hardhat-ts

yarn hardhat:test

Run the tests in the test directory

yarn hardhat:watch

Starts a local node, deploys contracts, updates the deployments/localhost folder with contract address and abi.

On contract update, will redeploy contract and update deployments folder.

yarn hardhat:deployalfa

Deploys the contract to Alfajores and records the address in the deployments/alfajores directory

yarn hardhat:deploycelo

Deploys the contract to Celo and records the address in the deployments/celo directory
