Allow Hardhat to deploy smart contracts

[pathornteng]

Problem

Currently, users will get Internal error when using Hardhat to deploy a smart contract. The transaction contains INVALID_SOLIDITY_ADDRESS error as shown in https://hashscan.io/#/testnet/transaction/0.0.46030734-1655918065-252797715?t=1655918078.085442000

Please feel free to use the following script to reproduce the problem

Note: I can use Truffle to deploy a smart contract to Hedera network just fine.

Solution

Hardhat might be using different formats or values. Further investigation is required.

Let's investigate why truffle works fine, does it just not check for a valid contract id?

As far as I can see, you are using a contract with console.logs in it.

That's not supported in Hedera, and the thrown error is INVALID_SOLIDITY_ADDRESS. Remove console.log lines and import statement from the head.

👇 Here is an example of a clean contract 👇

//SPDX-License-Identifier: Unlicense
pragma solidity ^0.8.0;

contract Greeter {
    string private greeting;

    constructor(string memory _greeting) {
        greeting = _greeting;
    }

    function greet() public view returns (string memory) {
        return greeting;
    }

    function setGreeting(string memory _greeting) public {
        greeting = _greeting;
    }
}

@natanasow You are right. I removed the console.log and it works!

Thanks for the answer :)
