Bitcoin: Getting error for transferring BTC using node js code, getting error “No inputs were signed”

Processing of Bitcoin Node.js Code: “Not Signed Inputs”

As a developer working with Bitcoin, you may have encountered the scandalous mistake “No entrances”. This problem can be disappointing, especially when building a system that requires the transfer of funds from one user to another. In this article, we will deepen why this mistake arises and provide guidance on how to resolve it with the help of node.js.

Understanding the error

When requesting Bitcoin (BTC) transfer to your code, the “Bitcoinjs-RSlibrary (a popular choice for the construction of Bitcoin-based applications) is trying to create a new transaction. However, if the recipient's portfolio signature is not signed correctly .

The "No Input" error is signed **

This error occurs when sender and receiver portfolios do not match private keys or their signatures are invalid. TheBitcoinjs-RSLibrary expects both sides to provide a valid signature for each entrance to the transaction (ie the transfer of UTXOS).

When you try to create a new transaction without signed entrances, the library casts an error stating that "no entrances are signed".

node.js code example

Let's take a closer look at how your specific Node.js code can cause this problem:

javascript

const bitcoin = require (‘bitcoinjs-rs’);

// load the wallet (UTXO) from a disk

const utxos = Loadwallet ();

// Create a new transaction without signed inputs

CONST TX = {

Sender: “Expenditure”, // Sender’s address

Receiver: “Expenditure”, // Recipient’s address

};

tx.inputs = [

bitcoin.transctioninput.new ({

Address: “Expenditure”,

Scriptsig: [bitcoin.sigtype.hmac, ‘0x1234567890abcdef’],

Scriptpubkey: [Bitcoin.Scriptpubkey.new ([Bitcoin.Scriptpubkey.Assign_Script Pubkey, ‘0x1234567890ABCDEF’]]]

}),

];

// Sign in transaction entrances

tx.inputs.foreach ((input) => {

Bitcoin.signtransction;

});

// attempt to create a new transaction without signed entrances

Const result = bitcoin.createtransction (TX);

`

Decision

To resolve this problem, you must ensure that both parties provide a valid signature for each entrance to the transaction. Here are some steps to follow:

• Load and check UTXOS : Load the UTXO portfolio from the disk and check their validity by checking their balance and property.

• Sign inputs

  : Use bitcoin.signtransction () to sign any input with the sender’s private key. You can use a library as bitcoinjs-wallet-node or to create your own realization for this step.

• Create a new transaction : Create a new transaction using bitcoin.createtransaction (), passing to the signed entrances.

Here’s an updated sample code fragment:

`javascript

const bitcoin = require (‘bitcoinjs-rs’);

// load and check UTXOS

const utxos = Loadwallet ();

utxos.foreach ((txo) => {

If (! bitcoin.verifytxhash (txo.hash, txo.outpoint)) {

Console.error (Invalid Transaction hash: $ {txo.hash});

return;

}

});

// Signs Inputs

Const Sender = bitcoin.createaddress (‘consumption’);

CONST receiver = bitcoin.createaddress (‘taking’);

const sendersign = bitcoin.signtransction ({{{{

sender,

Inputs: utxos.map ((txo) => {

return bitcoin.transctioninput.new ({{{{{{

Address: txo.address,

Scriptsig: bitcoin.sigtype.hmac, // Sign with the sender’s private key

Scriptpubkey: bitcoin.Scriptpubkey.new ([Bitcoin.Scriptpubkey.Assign_Script.pubkey, ‘0x1234567890abcdef’]]

});

}),

});

// Create a new transaction

const Result = bitcoin.createtransaction ({

Inputs: utxos.map ((txo) => {

return bitcoin.transctioninput.new ({{{{{{

Address: txo.address,

Scriptsig: bitcoin.sigtype.hmac, // Sign with the sender’s private key

Scriptpubkey: Bitcoin.Scriptpubkey.new ([Bitcoin.Scriptpubkey.Assign_Script.
