Why Stackfy

Crypto payments done right

Built for those who want to receive crypto without becoming a financial institution or handing custody of the money to third parties.

🔑

You hold the keys

Watch-only via xpub / public key. Stackfy only watches incoming payments — it never has access to your balance. Your private key never leaves you.

🪙

Multi-currency

Receive Bitcoin on-chain and USDT (Tron and Polygon) with automatic confirmation. More networks coming soon.

🎨

White-label

Checkout and dashboard with your brand — logo, colors and domain. Your customers see you, not us.

💸

No cut of your sales

You pay a fixed monthly subscription, not a percentage per transaction. Whether you receive R$10 or R$10k, the cost is the same.

⚡

Invoices in seconds

Create charges with the amount locked in fiat, converted to crypto on the spot. The customer pays, the system confirms and notifies.

🔔

Automatic alerts

Email and Telegram notifications at every step of the payment. Track everything from the dashboard, on mobile or desktop.

📝

Simple sign-up

A quick, non-invasive sign-up: a few steps and you're ready to charge.
