Diamond Tutorial

1) Clone the hardhat-1-diamond repo from Nick Mudge

git clone [https://github.com/mudgen/diamond-1-hardhat](https://github.com/mudgen/diamond-1-hardhat)

2) Change to the new directory

cd diamond-1-hardhat

3) Install dependencies

npm install

💡

Automatically verify your smatcontracts on etherscan by installing the extension with-

npm install --save-dev @nomiclabs/hardhat-etherscan

4) Edit hardhat.config

add Etherscan plugin import to allow for automatic smart contract verification
```
require("@nomiclabs/hardhat-etherscan");
```

add module exports

networks: {
    goerli: {
        url: "YOUR_QUICKNODE_HTTP_ENDPOINT",
        accounts: ["YOUR_PRIVATE_KEY"]
    }
},
etherscan: {
// Your API key for Etherscan
// Obtain one at [https://etherscan.io/](https://etherscan.io/)
    apiKey: "YOUR_ETHERSCAN_API_KEY"
}

5) Deploy Diamond

Compile code
```
npx hardhat compile
```

Deploy Diamond

npx hardhat run scripts/deploy.js --network goerli

6) Create script for facet deployment

// Deploy facets and set the `facetCuts` variable
console.log('')
console.log('Deploying facets')
const FacetNames = [
'DiamondCutFacet',
'DiamondLoupeFacet',
'OwnershipFacet'
]
// The `facetCuts` variable is the FacetCut[] that contains the functions to add during diamond deployment
const facetCuts = []
for (const FacetName of FacetNames) {
    const Facet = await ethers.getContractFactory(FacetName)
    const facet = await Facet.deploy()
    await facet.deployed()
    console.log(`${FacetName} deployed: ${facet.address}`)
    facetCuts.push({
        facetAddress: facet.address,
        action: FacetCutAction.Add,
        functionSelectors: getSelectors(facet)
    })
}

7) Deploy Facet

npx hardhat run scripts/deploy.js --network goerli

8) Verify Contract

Run the following command with your Facet smart contract address:
```
npx hardhat verify --network goerli DEPLOYED_CONTRACT_ADDRESS
```
