Introduction

Cregis Payment Engine offers a one-stop cryptocurrency payment solution for businesses. Merchants can quickly integrate the system through a simple API interface. We provide a pre-designed checkout page for immediate use, while also allowing merchants to customize their own interface based on specific needs. When a merchant initiates a payment request, the system generates a unique payment address, and funds are deposited into the Cregis wallet. Through a 10-minute automatic settlement mechanism, funds are swiftly transferred to the merchant's designated wallet. Merchants can use the Cregis desktop application to view order status, settlement data, and other transaction details at any time, making payment management effortless. We support multi-chain and multi-currency payments, ensuring efficient and flexible fund transfers, and delivering a secure and convenient cryptocurrency payment experience for our clients.
