      Foundry NFT

      This is a section of the Cyfrin Foundry Solidity Course.

      ⭐️ (7:40:56) | Lesson 11: Foundry NFT

      We go through creating 2 different kinds of NFTs.

      1. An IPFS Hosted NFT
      2. An SVG NFT (Hosted 100% on-chain)

      NFT Pug NFT Happy NFT Shiba NFT Frown NFT St.Bernard


      Getting Started

      Requirements

      • git
        • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
      • foundry
        • You'll know you did it right if you can run forge --version and you see a response like forge 0.2.0 (816e00b 2023-03-16T00:05:26.396218Z)

      Quickstart

      git clone https://github.com/Cyfrin/foundry-nft-f23
      cd foundry-nft-f23
      forge install
      forge build
      

      Optional Gitpod

      If you can't or don't want to run and install locally, you can work with this repo in Gitpod. If you do this, you can skip the clone this repo part.

      Open in Gitpod

      Usage

      Start a local node

      make anvil
      

      Deploy

      This will default to your local node. You need to have it running in another terminal in order for it to deploy.

      make deploy
      

      Deploy - Other Network

      See below

      Testing

      We talk about 4 test tiers in the video.

      1. Unit
      2. Integration
      3. Forked
      4. Staging

      This repo we cover #1 and #3.

      forge test
      

      or

      forge test --fork-url $SEPOLIA_RPC_URL
      

      Test Coverage

      forge coverage
      

      Deployment to a testnet or mainnet

      1. Setup environment variables

      You'll want to set your SEPOLIA_RPC_URL and PRIVATE_KEY as environment variables. You can add them to a .env file, similar to what you see in .env.example.

      • PRIVATE_KEY: The private key of your account (like from metamask). NOTE: FOR DEVELOPMENT, PLEASE USE A KEY THAT DOESN'T HAVE ANY REAL FUNDS ASSOCIATED WITH IT.
      • SEPOLIA_RPC_URL: This is url of the goerli testnet node you're working with. You can get setup with one for free from Alchemy

      Optionally, add your ETHERSCAN_API_KEY if you want to verify your contract on Etherscan.

      1. Get testnet ETH

      Head over to faucets.chain.link and get some tesnet ETH. You should see the ETH show up in your metamask.

      1. Deploy (IPFS NFT)
      make deploy ARGS="--network sepolia"
      
      1. Deploy (SVG NFT)
      make deploySvg ARGS="--network sepolia"
      

      Scripts

      After deploy to a testnet or local net, you can run the scripts.

      Using cast deployed locally example:

      cast send <RAFFLE_CONTRACT_ADDRESS> "enterRaffle()" --value 0.1ether --private-key <PRIVATE_KEY> --rpc-url $SEPOLIA_RPC_URL
      

      or, to create a ChainlinkVRF Subscription:

      make createSubscription ARGS="--network sepolia"
      

      Base64

      To get the base64 of an image, you can use the following command:

      echo "data:image/svg+xml;base64,$(base64 -i ./images/dynamicNft/happy.svg)"
      

      Then, you can get the base64 encoding of the json object by placing the imageURI into happy_image_uri.json then running:

      echo "data:application/json;base64,$(base64 -i ./images/dynamicNft/happy_image_uri.json)"
      

      Estimate gas

      You can estimate how much gas things cost by running:

      forge snapshot
      

      And you'll see and output file called .gas-snapshot

      Formatting

      To run code formatting:

      forge fmt
