How to pay with USDT
USDT on the TRON network (TRC20). Takes about 5–10 minutes. No account is needed.
Before you start: you need a wallet or exchange account that can send USDT on TRON (TRC20). The most common mistake is sending on the wrong network (for example ERC20/Ethereum). Wrong-network transfers cannot be recovered.
Step 1 — Create your order
On the books section, click “Buy this book”, enter your email address, choose the book language, tick the refund/terms box, and press “Continue to secure payment”.
Step 2 — You are redirected to NOWPayments
Our payment partner NOWPayments opens a private checkout page for your order. It shows:
- The exact USDT amount to send
- A TRON (TRC20) deposit address and QR code
- A countdown timer (the rate is locked for a limited time)
Keep this page open until the payment is confirmed.
Step 3 — Get USDT (TRC20)
Option A — From a crypto exchange
Buy USDT on an exchange that supports TRC20 withdrawals (for example Upbit, Bithumb, Binance, Bybit, OKX — availability depends on your country). Withdraw USDT and select TRON / TRC20 as the network, then paste the deposit address from Step 2.
Option B — With Trust Wallet and a card
Trust Wallet can buy crypto with a bank card through an in-app provider. Card availability, fees and identity checks vary by country.
- Install Trust Wallet from the official app store.
- Create a new wallet and write the recovery phrase on paper. Never share it with anyone, including us.
- Tap Buy and purchase USDT with your card.
- Make sure the USDT is on the TRON (TRC20) network. If it arrived on another network, use the wallet’s swap/bridge or send it back to the exchange first.
- Tap Send, choose USDT, paste the NOWPayments TRC20 address, enter the exact amount, select the TRON network, and confirm.
Card purchase costs more. Buying USDT with a card usually adds a 2–5% provider fee plus network fees, and may require ID verification. Paying from an exchange balance is cheaper.
Step 4 — Send the exact amount
- Network: TRON (TRC20) — not ERC20, BEP20 or Polygon.
- Amount: the exact USDT amount shown on the checkout page.
- Address: copy and paste; check the first and last characters.
- No memo/tag is required for TRC20.
Step 5 — Wait for confirmation
The status moves from waiting to confirming and then finished. TRON confirmations usually take 1–5 minutes, but can take longer during network congestion. If you close the page, you can reopen the same invoice link from your browser history.
Step 6 — Receive your PDF
After the payment is verified we email the PDF in the language you selected, normally within 24 hours. If you do not receive it, email lsgsg0908@gmail.com with your order number.
Common problems
- “Waiting” for a long time: the transfer may still be unconfirmed, or it was sent on another network. Check the transaction hash in your wallet.
- Invoice expired: create a new order from the site. Do not reuse an old address.
- Sent a different amount: the order will not be marked as paid automatically. Contact us with the transaction hash.
- Sent to the wrong network: contact the receiving platform; recovery is usually impossible.
Security: we will never ask for your wallet recovery phrase, private key, or remote access to your device. Always check that you are on shop.tcpssignal.com before paying.
