Collapsible content

What is a crypto payment gateway?

Crypto payment gateway is a system that allows you to receive, change, store and send payments in cryptocurrency. In order to receive payments in cryptocurrency, a business needs a technical system for processing crypto payments and a license allowing such activity. WhiteFlo offers its clients a technical solution for the operation of a crypto payment gateway business.

How can I launch a crypto payment gateway business?

If you want to launch your own cryptocurrency payment gateway for your existing clients in your core business, or start a cryptocurrency processing service business from zero, you will need a technical solution. WhiteFlo supports several functional modules that satisfy the requirements of various businesses interested in implementing a service related to crypto processing. Launching your own WhiteFlo-based crypto payment processing gateway will take from 2 weeks.

How do I create a crypto payment gateway?

First of all, you need to understand that the launch of such a business can be divided into two conditional parts. Technical part and operational. The technical part involves the software on which your business will run. WhiteFlo is a technical solution to ensure the operation of your own crypto payment gateway. By purchasing our solution, you will save a lot of time and will have a technically ready product within 2-4 weeks.

The operational part of the business includes registering a company, obtaining a crypto license and opening bank accounts for fiat transactions - these services can be provided by WhiteFlo partners (contact us for details). Also you need to pay attention to customer service staff, liquidity for the conversion operations, compliance and security policies and other activities necessary to conduct daily business.

How do you set up a WhiteFlo crypto payment gateway?

Setting up the environment and installing the system or individual WhiteFlo modules is done by the WhiteFlo product development team on your servers and the cost of this work is included in a fixed one-time payment.

What else needs to be done to run the software?

  • Buy Servers on Amazon Web Services.
  • Implement improvements if needed.
  • Buy a domain, connect an email provider.
  • Open an account with a KYC provider, in case you do not want to deal with the KYC procedure yourself.
  • Open Accounts on the exchange/s to get live rates and create reverse orders.
  • Open an account with a card payment provider if you intend to process cards.

I want to open a crypto processing business, how much money do I need to ensure it?

To ensure the operation of the crypto processing system, you need to have some liquidity to ensure your transactions. Please note that interacting with psp and banks you will not have instant access to funds (settlement time might be from 2 days to several weeks, depending on the provider) and if a transaction with your client involves instant processing, you will have to secure this transaction from your funds. As for cryptocurrencies, you might have the reserves on your cold wallet or connect accounts on the exchange to provide access to assets.

Instant Crypto Exchange and Business Wallet

Collapsible content

Which businesses are suitable for Instant Crypto Exchange and Business Wallet Software?

This module is suitable for businesses that provide deposit, custodial storage, exchange and withdrawal services for cryptocurrencies to their business clients. In their account, clients can go through KYC procedures, deposit and withdraw crypto and fiat, convert cryptocurrencies, as well as buy and sell (i.e. exchange) cryptocurrencies for fiat, via VISA/MasterCard cards or bank transfer. Important note: the module does not have a system for matching user buy and sell orders. This is a centralised service in which the client buys and sells assets from your site.

Is WhiteFlo exchange software?

There is no system for matching buy and sell orders in WhiteFlo. One of the WhiteFlo modules is designed to provide an instant exchange for users. But this module is NOT a CEX and therefore does not offer an order matching system, market making, spot trading and other standard CEX features.

Crypto Processing via API

Collapsible content

Which businesses is the Processing module suitable for?

This module is suitable for businesses that provide financial services to their clients and already have their own user interface. It provides an API that allows interaction between the user interface and the WhiteFlo backend, allowing cryptocurrency transactions to be made in your interface. This is ideal for neo-banks, Payment Service Providers (PSPs), Electronic Money Institutions (EMIs), or any other business that wants to add crypto transactions to their fiat services.

Fiat-to-Crypto Transactions Software

Collapsible content

What kind of businesses is Fiat-to-Crypto Transactions Software suitable for?

This module is suitable for businesses that want to offer their customers the opportunity to buy cryptocurrency with a VISA/MasterCard card payment. Unlike the business wallet functionality, when the cryptocurrency remains on the client’s balance in the system, in this case the purchased cryptocurrency is sent directly to the client’s external wallet, which is not connected to your platform in any way. The interface for card payment can be provided both as a page on the platform and as a widget on the merchant's website. Can be applied in a wide range of business cases.

What is a fiat-to-crypto transactions gateway?

WhiteFlo provides a module for purchasing crypto with Visa/Mastercard card payments. To ensure the operation of this module, you will need to sign an agreement with the card processing gateway. After integration with card processing, you will be able to accept crypto purchases through card payments and send the purchased cryptocurrency to the buyer's personal wallets.
