Quick answer: To accept USDT payments for your business, choose how you’ll receive funds — a self-custody wallet for full control, a crypto payment processor for automated checkout and fiat conversion, or an exchange tool like Binance Pay — then pick which blockchain network you’ll accept USDT on (Tron/TRC-20 is the cheapest and most popular), connect it to your store via a payment link, plugin, button, or API, and test before going live.
