Is there a way to deploy pure bytecode with hardhat?

Question

Is there a way to deploy pure bytecode with hardhat or remix?

Thanks

Yes, this is possible.

Given that you have the bytecode and the ABI, you can create a script like this at scripts/deploy.js:

const hre = require("hardhat");
const fs = require("fs")
const path = require("path")

async function main() {
  
  var abi = require('/path/to/your/abi.json');
  var bytecode = require('/path/to/your/bytecode.json');

  const Contract = await hre.ethers.getContractFactory(abi, bytecode);
  const deployed = await Contract.deploy("test string");

  await deployed.deployed();

  console.log(
    `🚢 done. Contract deployed to ${deployed.address}!`
  );
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Where your abi.json contains the ABI (standard JSON format). The bytecode.json is in the following form from using solc (under say another script ./compile.sh):

const output = JSON.parse(solc.compile(JSON.stringify(input)));
const bytecode = output.contracts['Contract.sol'].Contract.evm.bytecode.object;

Where input is obtained from something like (where yourCodeFile.sol is the name of your Solidity file, the one you are compiling):

const thePath = path.resolve(__dirname, '../', 'contracts', 'yourCodeFile.sol');
const source = fs.readFileSync(thePath, 'utf-8');

var input = {
    language: 'Solidity',
    sources: {
        'yourCodeFile.sol' : {
            content: source
        }
    },
    settings: {
        outputSelection: {
            '*': {
                '*': [ "*" ]
            }
        }
    }
};

Then you export that to the JSON file. And replace Contract with your relevant name of course.

I used the above, e.g., to deploy pure Yul code via Hardhat.

Also note that, with this method, you can put whatever bytecode you want in the /path/to/your/bytecode.json file and pass to Hardhat!

These two resources discuss how to deploy bytecode using Remix (might be dated):

Answer 3

Using ethers you can deploy a contract just from its bytecode using sendTransaction:

const [wallet] = await ethers.getSigners()
const txReceipt = await wallet.sendTransaction({ data: bytecode })
await txReceipt.wait()

Answer 4

This solution did not work for me--at least on Polygon Mumbai. The tx succeeds but no contract or bytecode is displayed, and there's an error stating that the contract doesn't have an address.
