USDT Payment & Settlement

Purchase

Plugins are priced in USDT; orders are created through the LemPay usdt channel. The platform verifies the callback signature, merchant ID, payment type, order amount, product name and the TRADE_SUCCESS status. After a successful payment, a permanent plugin entitlement is created.

Refund Window

The refund window is configured in the admin panel. Refunds revoke the download entitlement. If developer earnings are already available, the platform must apply a corresponding reversal, so the settlement cycle should at least cover the refund risk window.

Developer Earnings

Orders record the original amount, the platform fee percentage, the platform fee and the developer earnings. After a successful payment, earnings first enter "pending settlement" and can only be withdrawn after the larger of the "settlement cycle" and the "refund window" has passed.

Withdrawal

• Settlement currency: USDT
• Network: USDT-TRC20
• Minimum amount: configurable in the admin panel, default 100 USDT
• Fee: fixed amount or percentage, configurable in the admin panel
• Payout: manual, by an administrator
• Completion: admins must fill in the TRC20 transaction hash when confirming

Withdrawal status flows as "Pending review → Approved, pending payout → Completed"; rejection releases the frozen balance.
