Hello, I need you to develop php script - 4 functions which will do this:

1. php function - Generate Ethereum addresses for deposit
- save this address in encrypted format to database with all private keys, as I need to have control over these addresses

2. php function - Monitor generated Ethereum addresses for possible deposits
- monitor this address (via cronjob or other way) and once someone pay ether to it, send email

3. php function - Sweep the etheres from these addresses
- sweep the ethers from these generated addresses to one master ether address

4. php function - Sending defined amount of Etheres to defined Ethereum address
- function to create transaction with etheres, I enter amount and address and function sends it and provide tx num of the transfer

If someone know how to do it either via some public api like Blockcypher, or has own solution, please tell me...

For future, I also need the very same scripts for other crypto-currencies like Litecoin, Dash and Bitcoin Cash.

I will provide own domain with own hosting as I have WPS with WHM+Cpanel.
Payment can be done in any crypto or digital e-currency like Perfect Money, Advcash, Webmoney...

Thank you.
Peter

[Perfect Money to BitcoinsBitcoins to Perfect Money]

We need to code a callback scripts for our e-currency exchange website. We exchange various e-currencies and crypto-currencies. Problem is that all work is done manually. We need to switch to automatic exchange process.
Right now, when clients want to transfer from Perfect Money to Bitcoins, we always manually check the payment and then manually send Bitcoins. This is very time consuming and slow. We want to change it to automatic process.

You must have experience with bitcoins, blockchain, cryptocurrencies and e-currencies such as Perfect Money.

Security is the main goal. There will be API access to our accounts and it must be more than 100% safe against hackers. We did already automatization in the past and our account was emptied because some hacker was able to change payment API script via vulnerability described here: http://okpay.livejournal.com/685.html and with so called Tamper Data plugin for Firefox.

For this project, we need to make automatic scripts for the following exchange:
Perfect Money to Bitcoins
Bitcoins to Perfect Money

When client sends payment Perfect Money via SCI payment button, it calls callback php script. This script should validate the payment in Perfect Money (also check against data tampering) and then script should send bitcoins to the client's bitcoin address and send email with link to transaction ID on blockchain.info

And second which is vice versa: When client sends bitcoin payment, script should monitor it and once the payment gets 3 confirmations by bitcoin network, script will send money via Perfect Money API to client's Perfect Money account based on the order submitted on our website.

What does it mean:
- you need to understand Perfect Money API and bitcoins API

Our website is Goldux.com
You can go and submit new order for Perfect Money to Bitcoin and Bitcoin to Perfect Money so you can see what we do and what we want to automatize.

Our competitors with already automatic script:
https://coinomat.com/

Perfect Money API: https://perfectmoney.com/sample-api.html
Bitcoin API: https://blockchain.info/api

Please note that we want 100% secure scripts. We want to avoid another big losses. Please read also this article about Perfect Money API vulnerability which you need to avoid: http://okpay.livejournal.com/685.html

If we are satisfied with results, we can work with you on other type of transactions such as Perfect Money to Egopay, Bitcoins to Egopay, OKPay to Bitcoins, Bitcoins to OKpay. These all we want to automatize, so if you are good, future projects are yours.

Please do not bid if you dont have experiences with Bitcoins, Blockchain and at least one API of e-currency processor.

Thank you.
