Basic Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts.

Try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
node scripts/sample-script.js
npx hardhat help

npm run generateContractsArtifacts ( generate abi etc for smart contract ) // configuration overrided in hardhat to create artifact into src and be accessible from react npm run start ( start GUI ofc)

Using another network

    const provider:any = await detectEthereumProvider();
    // const chainId = await provider.request({ method: 'matic_chainId' });
    // const chainName = (ChainIdsEnum as any)[chainId];
    
    let accounts = await provider.request({ method: 'eth_accounts' });
    let c = await provider.request({
        "method": "wallet_switchEthereumChain",
        params: [{"chainId": "0x13881"}]
    })
    console.log(c);
    if ( accounts.length === 0 ) {
      accounts = await metamaskLoginModel(provider)
    }
};
