Describe the bug

Hello everyone, I am facing an issue while trying to upload my smart contract on the Sepolia testnet network. Although the deployment is successful and I can view the transaction on Sepolia Etherscan, the input data for the contract is empty. Also when I am trying to verify the contract I receive this error "Error: Etherscan could not detect the deployment."

I would highly appreciate it if you could help me with this.

here is my script contract code

`//SPDX-License-Identifier: MIT pragma solidity ^0.8.20;

import {Script} from "forge-std/Script.sol"; import {Chatter} from "../src/Chatter.sol";

contract ChatterScript is Script {

function run() public{
    vm.broadcast();
    new Chatter();
}

} `

Such error usually means that you have to wait a bit while Etherscan is indexing your contract. If that happens, running script with --resume flag after some time should help

I did, but unfortunately I am getting the same error again. Also the contract itself has no input data on Etherscan for Sepolia network again.

does the deployed contract has any code? can you share the deployment transaction?

No there is no code within the contract. This is the transaction hash "0x12f248de3fd27fcb7b0f03a845d8c1819860583d54271bbdbfcc68399ea5ff1a"

[klkvr]

right, so this is basically a CREATE transaction with empty data, this contract can't be verified.

Can you reproduce this reliably? Does script artifacts look correct?

Yeah everything looks fine I just double checked it.

[zerosnacks]

Marking as invalid as the deployed contract is empty (0x)

Your contract will need to be more substantial in order to be verified

Feel free to re-open with an additional minimal reproduction

[notchuks]

@zerosnacks the contract has some code. I am having the exact same issue. Here is the smart contract;

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.13;

contract Chat {
    event Message(address indexed sender, string message);

    function sendMessage(string calldata message) public {
        emit Message(msg.sender, message);
    }
}

After deploying on sepolia, the verification times out.

[klkvr]

@notchuks are you on latest nightly? thinking this might have been fixed by https://github.com/foundry-rs/foundry/pull/8532

[notchuks]

@klkvr I will run foundryup right now and retry this. Thanks for the speedy response.

[notchuks]

It times out with the same response: Etherscan could not detect the deployment. Here is the contract address: 0x470bCcb64Abce80b0618E6c8F59E610738F9AaAa

[klkvr]

do you mind sharing script artifacts from broadcast/ folder? also are you using a public RPC you could share?

[notchuks]

Hey @klkvr, sorry for the delayed response. Here is the script artifacts; and I am using a local RPC from the frame wallet. it is exposed as http://localhost:1248 on my pc.
