My main concern is not a difference, but the different execution of these functions doesn't allow me to procceed. My code where I have a problem: const { network, ethers } = require("hardhat")
const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")
const VRF_SUB_FUND_AMOUNT = ethers.parseEther("1")
const BASE_FEE = ethers.parseEther("0.25")
const GAS_PRICE_LINK = 1e9
module.exports = async function ({ getNamedAccounts, deployments }) {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const chainId = network.config.chainId
let vrfCoordinatorV2Address, subscriptionId, vrfCoordinatorV2Mock
if (chainId == 31337) {
vrfCoordinatorV2Mock = await ethers.getContractAt("VRFCoordinatorV2Mock", deployer)
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target
console.log(vrfCoordinatorV2Address)
const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
const transactionReceipt = await transactionResponse.wait()
subscriptionId = transactionReceipt.logs[0].args.subId
await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
} else {The main concern is that (vrfCoordinatorV2Mock.createSubscription()) doesn't emit an event when executed, so logs[] and args are undefined. On the other hand, fcc script runs just fine with .getContract(""), which takes only 1 param. Another guy uses deployments.get to get his MockV3Aggregator address. But as far as I have tested, the deploymends.get will give you not the contract instance, but the address. I think so, because it doesn't allow me to call any function: vrfCoordinatorV2Mock = await deployments.get("VRFCoordinatorV2Mock", deployer)
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
console.log(vrfCoordinatorV2Address)
const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()And I am stuck in this position for 4 days, trying to figure out a way with this new cool hardhat update. In case you need it: {

deployments.get doesn't give you contract instance, it contains address, abi, bytecode and other stuff related to contract. vrfCoordinatorV2Mock = await deployments.get("VRFCoordinatorV2Mock")
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
vrfCoordinatorInstance = await ethers.getContractAt("VRFCoordinatorV2Mock", vrfCoordinatorV2Address, deployer)And you can use vrfCoordinatorInstance to call the functions on the contract. |
