{% hint style="success" %}
**Success Response:**\
If the OTP is enabled *(success.data.isOTP: true),* broadcasting the transaction will require an OTP to be authorized. \
Note that 1 TRX = 1000000 SUN. Amounts are denominate in SUN, for both USDT and TRX, which means you have to divide the amounts by 1,000,000 for user presentation.
