Deploy EVM smart contract

EVM smart contract deployment also requires tokens. Moreover, you have to pay more expensive commission for such kind of action.

To deploy an EVM smart contract:

  1. Revert the index.js file to its initial state, described here.

  2. Replace the first line in the file:

    import { NetworkApi, WalletApi } from '@thepowereco/tssdk';


    import { NetworkApi, WalletApi, TransactionsApi, EvmApi } from '@thepowereco/tssdk';

    The file will look like this:

    import { NetworkApi, WalletApi, TransactionsApi, EvmApi } from '@thepowereco/tssdk';
    import {readFileSync} from 'fs';
    //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);
  3. Add the following code to the file:

    //deploy smart-contract
    const code = readFileSync("greeter_sol_Greeter.bin");
    let deployTX= TransactionsApi.composeDeployTX(importedWallet.address,code.toString(),[],'',0,importedWallet.wif,"evm",networkApi.feeSettings,networkApi.gasSettings);
    let resDeploy=await networkApi.sendPreparedTX(deployTX);
  4. Start this code from the terminal using the following command:

    node index.js

As a result you will see a deploy contract transaction:

dcloud_example % node index.js
import data {
address: 'AA100001733086414002',
wif: 'KywHx4qhG49JEms15jmgXDGMq7xKkmhQSpiZihWi5bbvL8QvjyUD'
accountData {
amount: { SK: 110100000 },
lastblk: '82C1D404FEBC267FCDE33252F9965D7836934B755BC17E6D7AB9D763BDE5A37D',
preblk: 'CC0F76855B346A53AC8FA04F033B8150D92087AF98795ADBDAE8EA4CA7A57FD5',
pubkey: '0207FE4A91CE18E398B8BF7DF7B3BF13D99712C1DB8F3FA856E43C9839452424E1'
{ txId: '3VWq91nneRZR5uXcR-c1033.gemsfinder', res: 'ok' }

The contract must be deployed on an address, specified by the first parameter of the composeDeployTX function. In the case described in these docs, the contract is now at the following address:
