Unable to deploy Ink smart contract to the local node.

[Subway2023]

Reference link: creating-an-ink-project, hardhat-deployment Problem: unable to successfully deploy the contract following the documentation. Aim: deploy the Ink contract with a Solidity-compatible ABI and invoke it for differential testing

ink smart contract project

cargo contract new flipper

Change abi = "ink" to abi = "sol" in Cargo.toml

cargo contract build

hardhat project

mkdir hardhat-example
cd hardhat-example
npm init -y

npm install --save-dev @parity/hardhat-polkadot

npx hardhat-polkadot init
npm install

hardhat.config.js（the document does not include global.WebSocket = require("ws");, which will cause an error.）

global.WebSocket = require("ws"); 

require('@nomicfoundation/hardhat-toolbox');
require('@parity/hardhat-polkadot');

module.exports = {
  // ... other config
  networks: {
    hardhat: {
      polkavm: true,
      nodeConfig: {

start node

npx hardhat node

deploy

first error

npx hardhat run scripts/deploy.js --network localNode --no-compile

another error

if i modify url: http://127.0.0.1:8545 to url: http://127.0.0.1:8000 in hardhat.config.js, there is another error

npx hardhat run scripts/deploy.js --network localNode --no-compile

Hi! I’m the author of this tutorial https://use.ink/tutorials/ethereum-compatibility/hardhat-deployment .

I can reproduce your issue. I’m not yet sure what changed that prevents deploying an ink! contract with Solidity metadata, whether it’s in ink-node or due to recent changes in hardhat-polkadot.

Have you tried deploying the example Solidity contract from the docs? https://docs.polkadot.com/develop/smart-contracts/dev-environments/hardhat/#set-up-hardhat. I tried and hit an issue as well: https://github.com/paritytech/hardhat-polkadot/issues/306

@AlexD10S Could you try deploying the contract via e.g. polkadot-js? It's not a nice API, but this will already tell you if there's a more general error.

Deployment works with PolkadotJS on v6.0.0-alpha.4: Hardhat still fails with the same issue as @Subway2023. @davidsemakula , any suggestions on what to try next?

Alright, looking into this
