How to accept Bitcoin and USDT in your business?
What you need
- A wallet whose keys you control: an xpub for Bitcoin; a USDT address on Tron (TRC-20) or Polygon.
- A Stackfy account (signup is quick).
You don't need to become a financial institution or hand over custody of the money: just register the public key and you're set.
Why accept crypto — especially in Brazil?
Brazil is one of the largest crypto markets in the world, and stablecoins like USDT play a central role in the flows.
Stablecoins drive this: in the same period (Jul 2024–Jun 2025), more than half of exchange purchases made in reais (BRL) were stablecoins (Chainalysis). Accepting Bitcoin and USDT puts you where that volume already is — without relying on cards or paying a slice of every sale.
Step by step with Stackfy
- Create the account and set up your store.
- Register the wallet (BTC xpub and/or a USDT address on Tron/Polygon).
- Create a charge in the dashboard (amount in reais, converted to crypto on the spot) or integrate via API in your site/e-commerce.
- The customer pays in a ready-made checkout (QR + address) and you get the confirmation by email, Telegram and webhook.
Bitcoin, USDT-Tron or USDT-Polygon?
Bitcoin is the best-known and most globally recognized asset. USDT (a dollar-pegged stablecoin) avoids volatility — ideal for prices in a stable value. Among networks, Tron and Polygon have low fees; you can offer both and let the customer choose at checkout.
Frequently asked questions
Do I need technical knowledge to start?
No. From the dashboard you create charges without code. To automate on your site, there's a REST API with ready documentation.
Is there a per-transaction fee?
No. The model is a fixed monthly subscription, so the cost is the same whether you receive R$10 or R$10k.
Where does the money land?
Straight in the wallet you registered (non-custodial). Stackfy never holds the funds.
Which USDT networks are supported?
USDT on the Tron (TRC-20) and Polygon networks, with automatic on-chain confirmation.
