1. Deposit or Purchase USDT
1. On‑Chain Deposit
- Open BiyaPay, tap Transfer In → On‑Chain Deposit.
- Select the coin USDT and the protocol type (we recommend TRC20), then generate a deposit address and QR code.

2. Buy Coins via a Third‑Party Exchange (Example: OKX)
Purchase Steps
- Visit the OKX website and download the official app (registration link).
- Complete account registration, login, and identity verification.
- Go to Quick Buy, enter the purchase amount, select USDT, and pay with WeChat, Alipay, or a bank card.

Withdraw to BiyaPay
- In BiyaPay, follow the On‑Chain Deposit steps above to obtain a USDT‑TRC20 address.
- In OKX → Assets → Withdraw, choose USDT‑TRC20, paste the address, enter the amount, and submit the withdrawal.
- After on‑chain confirmation, the USDT will appear in your BiyaPay account.

3. Use BESTOTC for Quick Purchase
- In BiyaPay go to Buy & Sell, select Quick Buy USDT → BEST.
- Enter a CNY amount (we suggest ≥ 1,000 CNY) or a USDT quantity, then click Quick Buy USDT.
- Choose Alipay or WeChat Pay, confirm, and an order will be generated.
- After payment, click I Have Completed the Transfer; once the counter‑party confirms, the USDT will be credited to your account.


2. Sell or Withdraw USDT
1. Withdraw to Another Exchange or Wallet
- BiyaPay → Transfer Out → On‑Chain Withdrawal.
