How to Set Up Cryptocurrency Acceptance with OpenCart?

There are two ways to accept cryptocurrencies. OpenCart CRM integration supports manual method and automated plugins.

1. Manual Method

The owner gives customers a static wallet address.
The customer transfers funds manually and sends a transaction screenshot by email.
The owner checks receipt in a blockchain explorer and confirms the order manually.

Disadvantages of the manual method:

• Processing time: 30–60 minutes per order.
• Human errors: 12% of transactions require additional verification.
• Impossible to track payment–order correspondence under high load.
• Customers may transfer inaccurate amounts due to exchange rate fluctuations.

2. Automated Plugin

The module creates a unique address for each order.
The system tracks receipts through the blockchain API and automatically confirms the order upon receiving the required amount.

Advantages of automation:

• Processing in 2–15 minutes without human involvement.
• Support for 15+ cryptocurrencies simultaneously.
• Automatic exchange rate recalculation every 30 seconds.
• Integration with inventory management system.
• Customer notifications via email/SMS.
