We are trying to implement a Utility NFT where subscription, royalty for the creator, and rental facilities are available, the NFT will be disclosed on the closing date, and the wallet address will be whitelisted prior to that. Utility non-fungible tokens (NFTs) are digital assets that represent a right or access to a service or product. They are similar to traditional NFTs in that they are unique and cannot be exchanged for other tokens on a one-to-one basis, but they differ in that they have a specific use beyond being a collectible or piece of artwork.

- git
- You'll know you did it right if you can run
git --version
and you see a response likegit version x.x.x
- You'll know you did it right if you can run
- Nodejs
- You'll know you've installed nodejs right if you can run:
node --version
and get an output like:vx.x.x
- You'll know you've installed nodejs right if you can run:
- Yarn instead of
npm
- You'll know you've installed yarn right if you can run:
yarn --version
and get an output like:x.x.x
- You might need to install it with
npm
orcorepack
- You'll know you've installed yarn right if you can run:
git clone https://github.com/soumalya340/erebrus-contracts
cd erebrus-contracts
yarn
yarn hardhat
Deploy:
npx hardhat run scripts/deploy.js
npx hardhat test
npx hardhat coverage
You can estimate how much gas things cost by running:
npx hardhat test
And you'll see and output file called gas-report.txt
If you'd like to run your own local hardhat network, you can run:
npx hardhat node
And then in a different terminal
npx hardhat run scripts/deploy.js --network localhost
And you should see transactions happen in your terminal that is running npx hardhat node
If you use metamask with a local network, everytime you shut down your node, you'll need to reset your account. Settings -> Advanced -> Reset account. Don't do this with a metamask you have real funds in. And maybe don't do this if you're a little confused by this.
- 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
- Get testnet ETH
Head over to faucets.chain.link and get some tesnet ETH. You should see the ETH show up in your metamask.
- Deploy
=======
npx hardhat run scripts/deploy.js --network maticmum
>>>>>>> (goerli update)
If you deploy to a testnet or mainnet, you can verify it if you get an API Key from Etherscan and set it as an environment variable named ETHERSCAN_API_KEY
. You can pop it into your .env
file as seen in the .env.example
.
However, you can manual verify with:
npx hardhat verify --constructor-args arguments.js DEPLOYED_CONTRACT_ADDRESS
To check linting / code formatting:
yarn lint
or, to fix:
yarn lint:fix
