Calling EVM smart contract function locally

You can call EVM smart contract function locally to get the data from contract. To do this:

  1. Ensure you are in dcloud_example directory.

  2. Start callScTx.js by running the following command:

    node callScTx.js

    Code example and comments:

    import { NetworkApi, WalletApi, EvmCore, EvmContract } from '@thepowereco/tssdk';
    import {readFileSync} from 'fs';
    import greeterAbi from './greeter_sol_Greeter.json' assert { type: "json" };

    //load account data from file
    const importNetworkApi = new NetworkApi(1025);
    const importWalletApi = new WalletApi(importNetworkApi);
    let password='111';
    const importedData = readFileSync("example.pem");
    const importedWallet = await importWalletApi.parseExportData(importedData.toString(), password);
    console.log('import data',importedWallet);

    //load balance for account
    const letNetworkApi = new NetworkApi(1025);
    await letNetworkApi.bootstrap();
    let subChain = await letNetworkApi.getAddressChain(importedWallet.address);
    const networkApi = new NetworkApi(subChain.chain);
    await networkApi.bootstrap();
    const walletApi = new WalletApi(networkApi);
    const accountData= await walletApi.loadBalance(importedWallet.address);

    //call function from smart-contract locale
    const EVM = await;
    const storageSc = await,importedWallet.address, greeterAbi);
    const greetMessage = await storageSc.scGet(

    //call function from smart-contract in blockchain
    const resSet = await storageSc.scSet(
    ['New hello!'],

The command outputs the following:

   % node callScTx.js
