Prestashop plugin needed

General Idea: To create a plugin to accept cryptocurrencies as a payment method on a website. Where the store manager has the option to decide about the payments, exchange it for EUROS or keeping in crypto. Cryptocurrencies to accept: BTC, BCH, BTG, ETH, DASH, LTC, XMR, TUSD The exchange rate showed to the client has to include an extra X% (our fees). And this % has to be easy to change in a future. Client’s process: Choose the cryptocurrency to use on the payment. The amount in EUROS from the shopping cart is converted to crypto (exchange rate from Coin Marked Cap) + X % A QR code is generated with our address, so the client can send the payment. E-commerce Admin: After loged in, he can set up the payments as he want. He can decide to exchange 100% of the payments into EUROs, or keep 100% of crypto, or X %. The plugin we want is very similar to this open source plugin: [login to view URL] So you can create a new one, or just modify that one, it's up to you.
