⚠️ Important Notice: Wallet Address Usage Restrictions

Due to the platform's use of a shared wallet address pool (polling mode), the wallet address allocated to each order is only valid during the current order's validity period:

• The wallet address is valid for 2 hours;
• Once the address expires, it will be reclaimed and may be reassigned to another order;
• Do not cache, save, or reuse this address for payment operations;
• If users repeatedly send payments to an expired address, the funds cannot be identified and assigned, which may result in loss, and the platform will not bear responsibility.

Developer Recommendations

• On the checkout page or next to the payment QR code, clearly remind users: "The address is only valid for this payment. Please complete the payment within 2 hours and do not save or reuse it."
• Merchants' backends should avoid caching addresses and should refer to the cashierExpireTime field returned when the order is generated to actively control the frontend countdown or disable payments after expiration.

Sample Message (for frontend display)

⚠️ This payment address is for this transaction only. Please complete the payment within 2 hours. The address will be reclaimed after expiration, and repeated payments to this address may result in the risk of lost funds!
