  • 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)

git clone https://github.com/Miguer-dev/smart_contract_nft
cd smart_contract_nft
forge install
forge build

make anvil

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

make deploy-puppy
make deploy-star

See below

forge test

or

forge test --fork-url $GOERLI_RPC_URL

forge coverage

1. Setup environment variables

You'll want to set your GOERLI_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.
  • You can learn how to export it here.
• GOERLI_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.

2. Deploy (IPFS NFT)

make deploy-puppy ARGS="--network goerli"

3. Deploy (SVG NFT)

make deploy-star ARGS="--network goerli"

4. Mint

make min-puppy ARGS="--network goerli"
make min-star ARGS="--network goerli"

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

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

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

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

You can estimate how much gas things cost by running:

forge snapshot

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

To run code formatting:

forge fmt
