Quick start

Get up and running with Hive TX in minutes

1

Install the package

Install Hive TX using your preferred package manager:
npm install hive-tx
Requires Node.js 20 or higher
2

Import and create a transaction

Import the required classes and create your first transaction:
import { Transaction, PrivateKey } from 'hive-tx'

const tx = new Transaction()
await tx.addOperation('vote', {
  voter: 'your-username',
  author: 'post-author',
  permlink: 'post-permlink',
  weight: 10000 // 100%
})
3

Sign and broadcast

Sign the transaction with your private key and broadcast it to the network:
const key = PrivateKey.from('your-private-posting-key')
tx.sign(key)
const result = await tx.broadcast()
console.log('Transaction ID:', result.tx_id)

{
  "tx_id": "abc123...",
  "status": "unknown"
}
