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:

   callScTx.js

   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);
   console.log('accountData',accountData)
   
   //call function from smart-contract locale
   const EVM = await EvmCore.build(networkApi);
   const storageSc = await EvmContract.build(EVM,importedWallet.address, greeterAbi);
   const greetMessage = await storageSc.scGet(
   'greet',
   [],
   );
   console.log(greetMessage);
   
   //call function from smart-contract in blockchain
   const resSet = await storageSc.scSet(
   importedWallet,
   'setGreeting',
   ['New hello!'],
   );
   console.log(resSet);

The command outputs the following:
