JavaScript code for build signed transaction and generating wallet and address

Create new address

const xels = require('/src');

Create wallet randomly

Call getWallet method of address object without passing any parameter for generating address and private key randomly

 let wallet1 = xels.address.getWalelt() //random
 console.log('Wallet(Random)',wallet1);

Create wallet from private key

Call fromPrivateKey method of address obejct by passing private key string to gererate wallet

 let wallet2 = xels.address.fromPrivateKey(private_key) //from private key
console.log('Wallet(From Private key)',wallet2);

Create wallet from random string

pass any string to generate wallet from the string

 let wallet3 = xels.address.getWalelt('Random String') //from static string
 console.log('Wallet(From String)',wallet3);

Create a raw tranaction

Require Transaction class from src folder to build a raw transaction

 const { Transaction } = require('/src')

let txobj = new Transaction()

let FEE = 10000; // in satoshi
let send_amount1 = 12*100000000; // in satoshi

Adding a input object

Call addInput method multiple times by object for multiple input or passing a array of object for multiple inputs

txobj.addInput(utxos);

Add Output

Call this addOutput method of Transaction object to add output address.you can call this method multiple times for multiple output to send xels

txobj.addOutput(xels_address,send_amount1)

//If you sent satoshi to multiple addresses the total amount will be the sum of those.
let total_send_amount = send_amount1;

Addd change address

Calculate and add chagne address by call addChange method of Transaction object to receive rest of balance amount of the address

let change_amount = txobj.balance - (total_send_amount+FEE);

if(change_amount<0){
    throw 'Insufficient Balance';
}

if(change_amount>0){
    txobj.addChange(chaneg_address,change_amount)
}

Sign Inputs

Signing all inputs by sender's private key.Call signInput method of Transaction object.

txobj.signInput(private_key);

Get hex

Call toHex method of Transaction object for getting transction hexa string

let hex = txobj.toHex() // Need to publish this transaction hex

• You will get transaction id after broadcast a transaction*

Get UTXOS from xels node

let xelsNode = new XelsNode('http://localhost:37221');

xelsNode.getUtxos(from_address).then(utxos=>{
    console.log(utxos)
})

Broadcast Signed transaction hex

xelsNode.broadcast(hex).then(resp=>{
        console.log(resp)
    }).catch(err=>{
        console.log(err);
    })
