How to run the frontend:

Prerequisites

• Node.js > 12
• Yarn Classic, aka Yarn v1, you can install it using this guide. If you are using macOS a simple brew install yarn should work.

Contract

Compile

On a terminal, install all the dependencies:

cd contract
yarn install
yarn compile

Deploy on a local node

Launch a local node

On a terminal

cd contract
yarn exec hardhat node

This command launch an HTTP and WebSocket JSON-RPC server @ http://127.0.0.1:8545/, you can use it as Web3 Provider on Remix.

Deploy it

On another terminal, deploy it

cd contract
yarn deploy

Deploy on a Testnet

Prerequisites

• An Alchemy account with a valid project on a Testnet (I suggest Mumbai Polygon testnet).
• An account with some funds on the chain selected before, if you choose Mumbai you can obtain them on the official faucet
• The choosen testnet available as Network in MetaMask, you can add Mumbai Testnet from here. (You can find a longer guide here)

---

1. Rename contract/.env.example in contract/.env and put in it the API_URL that can be found in the Alchemy Dashboard.
2. Export your MetaMask private key and put it in the PRIVATE_KEY field in the .env file
3. Uncomment the mumbai part in contract/hardhat.config.js
4. Run yarn deploy:testnet

Frontend

Run

On terminal:

cd frontend
yarn install
yarn start 

You can now visit http://localhost:3000/

Run using Docker

cd frontend
docker build -t blockchain-frontend .
docker run -p 8000:80 blockchain-frontend:latest

You can now visit http://localhost:8000/

The easiest way to test Frontend + "Backend"

1. Launch a local node, as described here
2. Deploy the contract on a local node, as described before
3. Connect MetaMask to http://127.0.0.1:8545/
4. Import an Account on Metamask from the private key printed on terminal in step 1, as described here
5. Open contract\artifacts\contracts\NFTSwap.sol\NFTSwap.json and paste the content into frontend\src\contracts\contract-abi.json.
6. Edit frontend\src\utils\blockchain.js with CONTRACT_ADDRESS obtained in point 2
