See what our customers have to say about CoinPay
āCoinPay made integrating crypto payments into our e-commerce platform incredibly simple. The API is well-documented and the support team is responsive.ā
āWe switched from a custodial solution and couldn't be happier. Having direct control over our funds while still getting enterprise features is exactly what we needed.ā
āThe automatic fee handling alone saves us hours every week. No more manual calculations or surprise gas fees eating into margins.ā
āSetup took less than 30 minutes. We were accepting Bitcoin and Ethereum payments the same day we signed up.ā
āThe webhook system is rock solid. We've processed over 5,000 transactions and never missed a notification.ā
āFinally, a payment gateway that doesn't hold our funds hostage. Transactions go directly to our wallet with full transparency.ā
