This is good value for money and I will discuss it with our Team to see if this is a viable option for our coin at this time. I believe the price for what you are offering seems pretty reasonable to me.  Smiley

I am very happy with your service!!

We used EcuaMobi's API service for a coin recently and wow what a professional!
This is real value for money and the service offered is really 1st class. This service comes
highly recommended by me and I do not usually recommend services on BCT.

This is a great deal, do not miss out!

I'm offering to install a gateway to allow any merchant to accept your crypto-currency as payment.

This will allow several merchants to easily accept your coin as payment, increasing the usability and price of that coin.

tl;dr

For only BTC0.85 worth you can offer a complete gateway to allow any merchant to receive your coin as payment.
I also include a fully working PHP code so merchants can implement it as easily as possible.



How it works

  • You get a server and install your coin's daemon on it.
  • I install the gateway on your server and provide a sample PHP code for the user.
  • Any user can use your gateway to accept your coin as payment. Your gateway will generate a new address for every user's transaction.
    Once a payment is received, it will automatically forward the payment to the address the user specified and will instantly notify the user's server.

The system works similarly to blockchain.info's API (https://blockchain.info/api/api_receive) so if a merchant is already implementing that to accept bitcoins
it will be extremely easy for them to start accepting your coin too.

While this system is similar to blockchain.info's, it's 100% my own code and it has an extra layer of security (added hashed signature to every notification, see Security below).

Here's the diagram of the final system:



Security

  • The code is PHP and MySQL so you can fully check it. However it's not open-source. You may not share it.
  • It has the same security measures as blockchain.info's API. For example, it allows merchants to add a security key in the URL to be called by the gateway. This prevents false calls faking a payment. This security system can fail if the attacker intercepts the communication between the gateway and the merchant.
  • Unique security: When the merchant asks for a new address, the gateways generates and sends a unique salt code which is saved by the merchant. Every call from the gateway to the merchant will be signed using that key.
  • You can set up the number of confirmations before forwarding the funds and notifying the merchant to prevent double spends.
  • The funds stay in your server only for a few minutes. It won't become the target of any hacker.


Working example

You can see a working example here:
https://api.captcoin.com/
(Note: Ticker and Address is not included.)

It allows any merchant to integrate CAPTcoin payments.

Easy to implement by the Merchants

I will include an open-source PHP sample code to allow merchants to easily implement the Gateway.

Here's an example:

https://github.com/CAPTcoin/receive_payment_php_demo

Which is running here:
https://api.captcoin.com/demo/


Requirements

  • You need to provide a server.
  • It must already run the daemon/wallet of your coin.
  • You must provide a domain or subdomain (ex: api.yourco.in).
  • Not required but highly recommended: You should have a trusted SSL certificate to enable HTTPS.


Cost

Temporarily for introduction the price is BTC0.85.
This is a small investment for a great added feature for your coin.

50% must be sent before I start working and 50% when it's done.
Or 100% can be sent to a trusted escrow before I start working.
