Gelato-NFT

Template project using Gelato VRF to generate randomized NFTs.

Setup

Clone the repo
Install forge modules forge install
Build the project: forge build

Test

Run forge test -vvv

Deploy

forge script ./script/DeployIceCreamNFT.s.sol --rpc-url ${rpcurl}

Verify contract

Populate ETHERSCAN_MUMBAI_API_KEY in .env or add a new network's etherscan api key in foundry.toml

mumbai = { key = "${ETHERSCAN_MUMBAI_API_KEY}" }
polygon = {key = "${ETHERSCAN_POLYGON_API_KEY}"}

In /broadcast/DeployIceCreamNFT.s.sol/${chainId}/run-latest.json, copy and note down

"contractAddress" - Deployed IceCreamNFT address.
"arguments" - Constructor argument (single address in the array).

Run the command

forge verify-contract ${contractAddress} IceCreamNFT --chain-id ${chainid} --constructor-args $(cast abi-encode "constructor(address)" "${constructor argument}")

e.g.

forge verify-contract 0xbde9e58E2D796e84502A68b8494faE1eb4c92CC2 IceCreamNFT --chain-id mumbai --constructor-args $(cast abi-encode "constructor(address)" "0xFD7089D182cB7b0005fF7dFdf8a86C828179a483")

Create VRF Task

Replace consumerAddress in CreateTask.s.sol with your consumer address.

    function run() public payable broadcast {
        address consumerAddress = address(0); // Replace this
        require(consumerAddress != address(0), "CreateTask.s.sol: Replace consumerAddress");
    }

Make sure the constructor argument for AutomateTaskCreator is correct. You can find the correct Automate address in the docs

    constructor() AutomateTaskCreator(address(0x2A6C106ae13B558BB9E2Ec64Bd2f1f7BEFF3A5E0)) {}

Run this command to create a VRF task.

forge script ./script/CreateTask.s.sol --rpc-url ${rpurl}

You can find the task id in the logs
