NewJun 16, 2026

Withdraw verify — second layer for withdrawals

Two-layer (second) verification for withdrawals — before a withdrawal is created, your backend must confirm it via webhook and return 200.

NewMay 25, 2026

PromptPay fiat withdrawals

Fiat withdrawals can now target a PromptPay proxy ID with the new promptpay_id_type field.

NewMay 22, 2026

Auto-convert deposits: THB ↔ USDT

Accept a deposit in one currency and be credited in the other automatically at the Binance TH rate — both USDT → THB and THB → USDT.
