Quick proof of concept for my boi @codyb and all the cryptokeepers at Definitely Crypto
-
It's @dhof's beautiful little LOOT contract
-
But with the flattened OpenZeppelin contracts extracted back into their original
imports, for cleanliness -
Then a healthy dose of
npx hardhatboilerplate (Advanced Example) which is A Pretty Great Way To Write Solidity -
And then this brilliant README
-
Good luck, we're all counting on you
Checkout this repo and install dependencies
git clone https://github.com/jamiew/loot-fork
cd loot-fork
npm install
compile the contract and deploy to the internal hardhat network
npx hardhat compile
npx hardhat run scripts/deploy.js
a real example requires you to run a local Ganache blockchain simulator (AKA the localhost network, chainId 31337):
# in one terminal, run a lil blockchain
npx hardhat node --show-stack-traces
# in another terminal, deploy the contract and copy the deployed address
npx hardhat run --network localhost scripts/deploy.jsthen start npx hardhat console and you can interact with said contract
npx hardhat console --network localhostin the console, connect to our newly deployed LootFork:
const Contract = await ethers.getContractFactory('LootFork');
const contract = await Contract.attach("ADDRESS_FROM_DEPLOYMENT_GOES_HERE");then let's call some contract methods:
(await contract.name()).toString()
// 'LootFork'
(await contract.totalSupply()).toString();
// '0'
// (because we haven't minted anything yet)
(await contract.getWeapon(1)).toString();
// '"Grim Shout" Grave Wand of Skill +1'if you want some loots, mint them to one of the default accounts setup by hardhat node (ganache). they cryptorich, they got like 10k ETH each
let tokenId = 1;
let account = (await ethers.getSigners())[0];
let txn = (await contract.connect(account).claim(tokenId));
let receipt = (await txn.wait());
console.log(receipt.events[0].args)
/*
[

to: '0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266',
tokenId: BigNumber { _hex: '0x03', _isBigNumber: true }
]
*/did it work though?
(await contract.totalSupply()).toString();
// '1'
(await contract.tokenURI(1));

congratulations jeffrey bezos u did it
or perhaps start with rinkeby, my favorite testnet
This largely requires funding a wallet and registering API keys with Alchemy and Etherscan
Copy .env.sample to .env and edit in your keys
Then:
npx hardhat run scripts/deploy.js --network rinkebyyou can interact with this contract via npx hardhat console the same way as above, just substitute --network rinkeby for --network localhost
You can also use the hardhat-etherscan-verify plugin to verify the contract on Etherscan, which is required to be truly eleet
npx hardhat verify --network rinkeby <YOUR_CONTRACT_ADDRESS>
Substitute mainnet for rinkeby to deploy for realsies. good luck
