Check the verification build before paying the balance and receiving source code. If AISTIM cannot complete the agreed cracking work and delivery, the deposit is refunded in full. If the project cannot continue for reasons attributable to the customer, including customer cancellation, the paid deposit is non-refundable. Delivery is normally within 10 hours and no later than 48 hours. Elapsed hours start once the required files and information are complete, the scope is confirmed and the deposit is received. A verification build is supplied first; source code follows customer approval and receipt of the balance. Time awaiting customer verification or payment is excluded from production time. We accept Alipay, PayPal and USDT. USDT is supported on TRC-20 and ERC-20; agree any other network in advance. Contact us to confirm payment details, network and amount. Project payments follow your quote; the website support link is for voluntary support.
