You can find runnable example in the following link

Prerequisites

Before we get started we need to make sure that all of the required dependencies are installed.

We recommend the usage of Yarn, but you can choose any other package manager you want!

yarn add @arkecosystem/crypto
yarn add @protokol/voting-crypto
yarn add @protokol/client
pnpm add @arkecosystem/crypto
pnpm add @protokol/voting-crypto
pnpm add @protokol/client
npm install @arkecosystem/crypto
npm install @protokol/voting-crypto
npm install @protokol/client

How To Create And Broadcast Nameservice Transactions

Create Proposal - Creating and Broadcasting

import { Identities, Managers, Transactions, Utils } from "@arkecosystem/crypto";
import { ProtokolConnection } from "@protokol/client";
import { Builders, Transactions as VotingTransactions } from "@protokol/voting-crypto";

export const CreateProposal = async (): Promise<void> => {
	// Configure our API client
	const client = new ProtokolConnection("http://localhost:4003/api");
	const passphrase = "clay harbor enemy utility margin pretty hub comic piece aerobic umbrella acquire";

	// Configure manager and register transaction type
	const configs = await client.api("node").crypto();
	const {
		body: {
			data: {
				block: { height },
			},
		},
	} = await client.get("blockchain");

	Managers.configManager.setConfig({ ...configs.body.data } as any);
	Managers.configManager.setHeight(height);
	Transactions.TransactionRegistry.registerTransactionType(VotingTransactions.CreateProposalTransaction);

	// Step 1: Retrieve the nonce of the sender wallet
	const senderWallet = await client.api("wallets").get(Identities.Address.fromPassphrase(passphrase));
	const senderNonce = Utils.BigNumber.make(senderWallet.body.data.nonce).plus(1);

	// Step 2: Create the transaction
	const transaction = new Builders.CreateProposalBuilder()
		.createProposal({
			duration: {
				blockHeight: 123456,
			},
			content: "QmPfdpTRbhGVZZWKZDzNT5T4NB6C7fFo5wM9Xe8qmLCXWt",
		})
		.nonce(senderNonce.toFixed())
		.sign(passphrase);

	// Step 3: Broadcast the transaction
	const broadcastResponse = await client.api("transactions").create({ transactions: [transaction.build().toJson()] });

	// Step 4: Log the response
	console.log(JSON.stringify(broadcastResponse.body, null, 4));
};

CreateProposal()
	.then(() => process.exit(0))
	.catch((error) => {
		console.error(error);
		process.exit(1);
	});
	

Cast Vote - Creating and Broadcasting

import { Identities, Managers, Transactions, Utils } from "@arkecosystem/crypto";
import { ProtokolConnection } from "@protokol/client";
import { Builders, Transactions as VotingTransactions } from "@protokol/voting-crypto";

export const CastVote = async (): Promise<void> => {
	// Configure our API client
	const client = new ProtokolConnection("http://localhost:4003/api");
	const passphrase = "clay harbor enemy utility margin pretty hub comic piece aerobic umbrella acquire";

	// Configure manager and register transaction type
	const configs = await client.api("node").crypto();
	const {
		body: {
			data: {
				block: { height },
			},
		},
	} = await client.get("blockchain");

	Managers.configManager.setConfig({ ...configs.body.data } as any);
	Managers.configManager.setHeight(height);
	Transactions.TransactionRegistry.registerTransactionType(VotingTransactions.CastVoteTransaction);

	// Step 1: Retrieve the nonce of the sender wallet
	const senderWallet = await client.api("wallets").get(Identities.Address.fromPassphrase(passphrase));
	const senderNonce = Utils.BigNumber.make(senderWallet.body.data.nonce).plus(1);

	// Step 2: Create the transaction
	const transaction = new Builders.CastVoteBuilder()
		.castVote({
			proposalId: "c8f3fff0df73f1125d15a467b4f9401a7967e2915c93612737b7761cde7ada29",
			decision: "yes",
		})
		.nonce(senderNonce.toFixed())
		.sign(passphrase);

	// Step 3: Broadcast the transaction
	const broadcastResponse = await client.api("transactions").create({ transactions: [transaction.build().toJson()] });

	// Step 4: Log the response
	console.log(JSON.stringify(broadcastResponse.body, null, 4));
};

CastVote()
	.then(() => process.exit(0))
	.catch((error) => {
		console.error(error);
		process.exit(1);
	});
