Submit Network Proposal using the icon-sdk-js

The process of submitting a network proposal requires signing a transaction calling the registerProposal method of the governance contract using your node validator wallet. The following section will describe how to use the icon-sdk-js to submit a network proposal.

The first step would be to initiate a nodejs project in a folder of your choice and install the icon-sdk-js by running the following command:

npm init -y && npm install icon-sdk-js

Add the keystore file to the root folder and edit the index.js file with the following code.

const IconService = require("icon-sdk-js");
const fs = require("fs");
 
const {
  IconWallet,
  IconBuilder,
  SignedTransaction,
  IconConverter,
  HttpProvider
} = IconService.default;

const rpcNodeUrl = "https://ctz.solidwallet.io/api/v3";
const keystorePath = "./keystore.json";
const keystorePassword = "password";
 
const httpProvider = new HttpProvider(rpcNodeUrl);
const iconService = new IconService(httpProvider);

 * @param {string} path - path to keystore file
 * @return {object} keystore object

  const keystore = fs.readFileSync(path, "utf8");
  return keystore;
}
 
/*

 * @param {object} params - proposal parameters

 * @return {string} transaction hash

 */
async function submitNetworkProposal(params, amount) {
  try {
    const wallet = IconWallet.loadKeystore(
      getKeystore(keystorePath),
      keystorePassword
    );
 
    const txObj = new CallTransactionBuilder()
      .from(wallet.getAddress())
      .to("cx0000000000000000000000000000000000000001")
      .stepLimit(IconConverter.toBigNumber("2000000"))

      .amount(amount)
      .build();
 
    const signedTransaction = new SignedTransaction(txObj, wallet);
    return await iconService.sendTransaction(signedTransaction).execute();
  } catch (err) {
    console.log(err);
  }
}
 
async function main() {
