Cryptocurrencies are changing the way people send, receive, and store value—and at the core
of crypto adoption for businesses is the crypto payment gateway. As the global economy
becomes more digital, accepting crypto payments is no longer just a trend—it’s a competitive
edge.
At FLLTECH, we help startups and enterprises integrate powerful blockchain solutions. Here’s
everything you need to know about crypto payment gateways and how they’re reshaping digital
commerce.
What Is a Crypto Payment Gateway?
A crypto payment gateway is a technology solution that enables merchants to accept
cryptocurrency payments from customers. Just like Stripe or PayPal does for fiat, crypto
gateways serve as the bridge between merchants and blockchain networks.
Popular supported cryptocurrencies include Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and
others like BNB, TRX, or stablecoins.
Gateways can:
●
●
●
●
Accept payments in multiple coins
Convert crypto to fiat in real-time
Process transactions with minimal fees
Generate blockchain invoices and transaction history
How Does It Work?
1. Checkout Integration – The gateway is integrated into a website or app.
2. User Pays in Crypto – At checkout, the customer selects a crypto payment option.
3. Blockchain Confirmation – The transaction is validated on the blockchain.
4. Payment Processed – The merchant receives crypto or equivalent fiat in their wallet.
Gateways can operate in two modes:
●
●
Custodial – The gateway handles wallet management (more centralized)
Non-Custodial – Users interact directly with the blockchain (more secure and
decentralized)
