Smart contract deployment

[antoniopucciarelli]

Hello community,

I got this problem when I run this in my console yarn hardhat run scripts/printoutData.js after the hardhat node is deployed with yarn hardhat node.

The contract is related to the YouTube lectures. You can find all the contract/files here: https://github.com/antoniopucciarelli/smartContract-test

Okay, so:

To deploy contracts on a local network, we SHOULD be using Mocks as Patrick explains in the video. I have given my version of the code for your interpretation of how it works to get a rough idea as to what to establish in your project.

Hope this helps!

My code:

if (chainId == 31337) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    // When going for a local network such as hardhat or localhost we should use a mock
    const args = [ethUsdPriceFeedAddress]
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: args, // Pricefeed address
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1, // If no blockConfirmations given in hardhat.config
    })

Hi @krakxn, thanks for the response.

As I got the MockV3Aggregator is related to the establishment of the price, so ETH/USD.

In my code I don't need this price setup because it's just a printout (contract/printout.sol).

The problem is with the deployment; it's like the node deploys the contract but then I cannot interact with it using the .js script.

Thank you for your help.

Try this in hardhat-config.js and let me know how it goes:

namedAccounts: {
        deployer: {
            default: 0, // here this will by default take the first account as deployer
            1: 0, // similarly on mainnet it will take the first account as deployer. Note though that depending on how hardhat network are configured, the account 0 on one network can be different than on another
        },
        player: {
            default: 1,
        },
    },

Sorry mate, still having the same issue.

1. Deploying node: yarn hardhat node
2. Running script: yarn hardhat run scripts/printroutData.js

[krakxn]

Change this to your liking and let me know if it helps. (in the file: printoutData.js)

const contractX = await deploy("ContractX", {
        from: deployer,
        args: args, // Pricefeed address, comment it out if not required
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1, // If no blockConfirmations given in hardhat.config
    })

Also, should wait 1 block - 6 blocks depending on the network for the back-end to process.

[antoniopucciarelli]

It doesn't work with this change either.

I got the same error message.

[antoniopucciarelli]

I searched on the web and I tried to run this time:

1. yarn hardhat node -> for node deployment -> the contract was already deployed when I called the node function.
2. yarn hardhat run scripts/01-deploy.js --network localhost and it successfully run.

@antoniopucciarelli You are not deploying the contract in the script.

Check out the hardhat-simple-storage-fcc repo or that part from the video.

[antoniopucciarelli]

I deployed the contract in the with a deploy script: deploy/01-deploy.js.

It's deployed on the local blockchain at the beginning.

[antoniopucciarelli]

My script follows the hardhat-FundMe lecture.

It should deploy the contract when yarn hardhat node is called, as you can see, but I cannot interact with the contract later on.

The hardhat-simple-storage-fcc you're talking about is also good but you need to deploy it with the script. I wanted to deploy it when the blockchain node is generated.

[alymurtazamemon]

@antoniopucciarelli yes --network localhost was the solution. Actually I thought that you are only running scripts, so you probably are on lesson 6 simple storage.

[antoniopucciarelli]

Ok, thanks for the help in any case.
Cheers.
