How to make a payment processor like Bitpay?

See the website: https://bitpay.com

1. The easiest way > run an instance of bitcoind: https://en.bitcoin.it/wiki/Bitcoind
With this then programmatically control the creation of wallets, addresses, and send/verify transactions.

2. Or, stronger, similar to bitpay: libbitcoin (used also by DarkWallet) >> http://libbitcoin.dyne.org/

3. When it comes to computer security, running these on an unsecured server could result in a hacker stealing all funds.

4. We need to be able to trade crypto and fiat currencies – BTL, EUR, LEU, BTC.

5. To set up a bitcoind server, and send JSON-RPC commands to it using the API: https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list
Once we know how these commands work, we’ll be able to build software that will accept payments.

6. For fiat currencies involved we have to deal with legal/regulatory concerns.

Possible to use this:
