It functions as a digital on-ramp — ideal for users entering the crypto world or platforms that want to onboard customers who don’t yet own cryptocurrency.

Key Features:

• Instant KYC/AML onboarding
• Real-time crypto pricing and execution
• Automatic wallet delivery
• Multichain and stablecoin support (BTC, ETH, USDT, etc.)
• API, SDK, or white-label integration for web and mobile apps

Top providers: MoonPay, Ramp Network, Transak, Banxa, Wert.io
