Ethereum: How to do sendRawTransaction to bitcoind JSON-RPC using bitcoin-core package in nodejs
Gere is an article explaining How to send a RawTransaction in JSON-RPC format use the Bitcoin Core package in.js.
Sending Raw Transactions in JSON-RPC Format with Bitcoin Core Package in Node.js
*
In this article, we will show you to to send a RawTransaction in JSON-RPC format use the Bitcoin Core package.
Prerequisites*
Before westart, make that you have a bar installed Also, that, that you have a Bitcoin Core node on your machine without a valid address for sensaction.
Install Required Packages*
To use the Bitcoin Core in Node.js, we need to install the bitcoin-core pute npm:
npm install bitcoin-core --save
Send Raw Transaction in JSON-RPC Format
The following code snippet demonstrates how to send a RawTransaction in JSON-RPC format use the Bitcoin Core pickage:
`javascript
const BitcoinCore = require('bitcoin-core');
// Set up Bitcoin Core Connction
Const bc = new BitcoinCore({
url: ' // replace with your Bitcoin Core node URL
});
// Create a new transaction object
const tx = {
version: 1,
hash: 'your_tx_hash_here',
from_address: 'your_from_address_here',
to_address: 'to_address_here', // optional
flags: 'raw' // optional, can be one of 'ful', 'confirm', or 'send-only'
};
// Create a new raw transaction object
const rawTx = {
tx_type: 'sendrawtransaction',
raw: tx
};
// Send the raw transaction in JSON-RPC format use Bitcoin Core
bc.sendRawTransaction(rawTx, (err, response) => {
if (err) {
console.error('Error sending raw transaction:', err);
} else {
// Get the transaction hash from the response
const txHash = response.hash;
console.log(Transaction hash: ${txHash});
}
});
`
In this example, we crate a newtransactionobed the the desired properties (verbs, hash, source, to address, and flags). We are create a new raw transaction obs. Finally, we send the raw transaction in JSON-RPC format use thesendRawTransactionmethod of the Bitcoin Coreconnection.
Notes*
*
- You can take the raw transaction by providing additional flags (e.g.,confirm
,send-only) or adjustting the properties of thes.
- The response from Bitcoin Core includes ahash` field for raw transaction. This hash can be used as a reference the integrity of the transaction.
By following thees, you chand is a book to send raw transactions in JSON-RPC format use the Bitcoin Core in.
