Thank a lot

Answer 1

You'll need the withdrawFunds method from the Kraken API (https://www.kraken.com/help/api#withdraw-funds).

Using the Poloniex API, you'll need to get your deposit address using returnDepositAddresses. If you don't have a deposit address for the given cryptocurrency, use generateNewAddress.

Kraken API Documentation: https://www.kraken.com/help/api

Poloniex API Documentation: https://poloniex.com/support/api/

1. create new API key with "Withdraw funds" right on kraken

   • Go to account settings then click on "api" to go to settings api page, then click on "generate new key"

   • Fill all field and tick the box "Withdraw Funds", then validate.

2. add the poloniex deposit address in kraken (assuming deposit address already created)

   • Go to funding deposit page then click on "withdraw" to go to funding withdraw page

   • Select the currency on the left side (here we assume that you want withdraw BTC) so you have to click on "Bitcoin (XBT)" on the left panel

   • Then click on "add address" then fill both "Description" & "Bitcoin address" field.

     Write down "Description" field because it will be required later when you will send API request to withdraw from Kraken to Poloniex.

3. Create the API request which will be sent to Kraken

Use the following code (re-use this example python library):

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import time
import requests
import urllib
import urllib2
import json
import hashlib
import httplib
import hmac
import random
import string
import base64

def _query( urlpath, req = {}, conn = None, headers = {}):
 """Low-level query handling.

 Arguments:
 urlpath -- API URL path sans host (string, no default)
 req     -- additional API request parameters (default: {})
 conn    -- kraken.Connection object (default: None)
 headers -- HTTPS headers (default: {})

 """
 uri = 'https://api.kraken.com'
 url = uri + urlpath

 if conn is None:
    conn = Connection()

 ret = conn._request(url, req, headers)
 return json.loads(ret)


def query_private( method, req={}, conn = None):

 #secret data
 key = "123456789_my_api_key"
 secret = "123456798_my_api_secret"

 apiversion='0'

 uri='https://api.kraken.com'
 urlpath = '/' + apiversion + '/private/' + method

 req['nonce'] = int(1000*time.time())
 postdata = urllib.urlencode(req)
 message = urlpath + hashlib.sha256(str(req['nonce']) +
                                   postdata).digest()
 signature = hmac.new(base64.b64decode(secret),
                     message, hashlib.sha512)
 headers = {
    'API-Key': key,
    'API-Sign': base64.b64encode(signature.digest())
 }

 return _query(urlpath, req, conn, headers)



withdraw_params={
    'asset': 'xbt',
    'key': "Withdrawal address Description",
    'amount': 0.25,

}

res=query_private('Withdraw', withdraw_params)
