Go to **Profile → Mode**.

* **Testnet** (default): buys settle on BSC testnet with tUSDT against test stock tokens, at the live mainnet price. Tap **Get 10,000 tUSDT** on Profile; no cooldown.
* **Mainnet**: real USDT and real stock tokens on BNB Chain.

See [Testnet and mainnet](/learn/testnet-and-mainnet) for what runs where.
