# Using UpdateProposal

The UpdateProposalOperation allows for updating proposals on the Hive blockchain.

# Creating an Update Proposal

Test it yourself: src/typescript/transaction/operations/update-proposal/creating-update-proposal.ts

import { createHiveChain, UpdateProposalOperation } from '@hiveio/wax';

// Initialize hive chain interface
const chain = await createHiveChain();

// Initialize a transaction object
const tx = await chain.createTransaction();

const proposalId = 1;
const creator = "your-account";
const dailyPay = chain.hbdCoins(100); // 100.000 HBD
const subject = "Proposal Update";
const permlink = "proposal-update";

tx.pushOperation(new UpdateProposalOperation({
    proposalId,
    creator,
    dailyPay,
    subject,
    permlink
}));

// Get a transaction object holding all operations and transaction TAPOS & expiration data, but transaction is **not signed yet**
console.log(tx.transaction);

# Adding an End Date to an Update Proposal

Test it yourself: src/typescript/transaction/operations/update-proposal/update-proposal-end-date.ts

import { createHiveChain, UpdateProposalOperation } from '@hiveio/wax';

// Initialize hive chain interface
const chain = await createHiveChain();

// Initialize a transaction object
const tx = await chain.createTransaction();

const proposalId = 1;
const creator = "your-account";
const dailyPay = chain.hbdCoins(100); // 100.000 HBD
const subject = "Proposal Update";
const permlink = "proposal-update";
const endDate = '2023-03-14' // You can also give end date as a timestamp, eg. 1678917600000

tx.pushOperation(new UpdateProposalOperation({
    proposalId,
    creator,
    dailyPay,
    subject,
    permlink,
    endDate
}));

// Get a transaction object holding all operations and transaction TAPOS & expiration data, but transaction is **not signed yet**
console.log(tx.transaction);
