How to generate a signature after successful transfer?

[prodigaLaugh]

After the transfer is successful, how to generate the signature. Use the generated signature to request the interface to be chained.

I don't understand your question. Please re-phrase it, and maybe paste some code if you're having problems.

What do you mean "generate"? Do you mean "retrieve the signature from inside the successful transaction"?

I don't understand.

Tell us what you want to do and we can help you find out what to do to accomplish that goal.

Transfer required parameters：

{
  "address": "string",//coin address
  "value": 12//transfer amount
}

and then data returned in the backend：

"data": [
    [
      {
        "hash": "string",
        "n": 0,
        "value": 10//coin amount
      },
     {
        "hash": "string",
        "n": 0,
        "value": 1//coin amount
      },
     {
        "hash": "string",
        "n": 0,
        "value": 1//coin amount
      },
    ]
  ]

transfer amout = data[0].value+data[1].value+data[2].value;

Then use the private key to encrypt the transaction to generate the signature, and then use the generated signature to request an interface, the data is wound.

I don't know how to process the returned data after the transfer. Then generate signatures, winding.

After the transfer is successful, I don’t know how to get it or generate a signature.

Here are some examples to help you learn how to use the TransactionBuilder object.

I am using a private node with two coinbase wallet

Wallet1.dat Wallet2.dat

with the help of rpc client, I am able to generate blocks and even get the mining reward in my coinbse account (Wallet1.dat) from it

now I have a hot wallet address like hw0 = 'mxxxxxxxxxxxxxxxxxxxxxxfdkajdkjxxxx'

I also have

privKeyWIF = 'afdhjafjkaxxxjjkajkdlxxjkflad' // assumed

I am able to transfer the amount from coinbase account(Wallet1.dat) to my hot wallet (hw0)

and now I want to transfer the amount from hot wallet(hw0) to wallet address like recever_wallet_address = 'mdfdxxxxxxmxxxxxxxxxmxxx'

can you help me to find out how I have to send it to

I have the amount and to address like below

const receiver = { to : 'm__recever_bitcoin_address', amount : 2 }

I have to broadcast this receiver transaction on my private node

how should I have to ... please help me with it

I am using

const Rpc_client = require('bitcoin-core'); to create my client // which had the coinbase address

now I want to use

const bitcoin_lib = require('bitcoinjs-lib');

to send the transaction from hot wallet to another address (recever_wallet_address)

(i am in a running project and not able to find out how I have to perform my action and this is the only place where I am getting a response from you guys)
