About OKX Exchange
OKX (originally OKCoin) was founded in 2013 by Star Xu. In its early days it focused on spot trading of Bitcoin and other cryptocurrencies, quickly becoming one of China’s largest crypto exchanges. To meet global demand and adapt to regulatory changes, the international site rebranded to OKEx in 2017 and began overseas expansion; it was renamed again to OKX in 2021 to better reflect its diversified and global business model.
Today, OKX has grown into a globally recognized digital‑asset trading platform, offering spot trading and derivatives for assets such as Bitcoin, Litecoin, Ethereum, and many others.

Complete Process for Creating a Web3 Wallet

- Tap Create Wallet to start the setup.

- Choose Create Now.

- Set a login password, then tap Continue.

- After creation, the system prompts you to back up the wallet. Choose Manual Backup and tap Continue.

Buying USDT on OKX
- After creating the wallet, switch back to the Exchange tab.

- On the home screen, tap C2C Buy to purchase crypto with fiat currency.

- The platform will list several merchants. It is advisable to pick a seller with high transaction volume and positive feedback, such as “Golden Trade Co.” (10,000+ trades, 99.94% positive rating). Tap the Buy button next to that merchant.

- Confirm the purchase amount again. The system will display the equivalent USDT amount (e.g., $500 ≈ 68.96 USDT) and remind you that non‑verified payments will be refunded automatically. Make sure you use a KYC‑verified personal account for the transfer. Tap Buy with 0% Fee.

- Tap Get Payment Details to retrieve the merchant’s receiving information.
