Build a Merchant Crypto Launch Kit for Agencies

Most developers think about crypto payments as an integration problem.

Many of them do not want to become crypto payment infrastructure experts. They need a safe, repeatable, documented way to deliver crypto payment functionality without rebuilding the same operational layer for every client.

That is where a developer can create a valuable product.

This article breaks down how to build that product.

I will use creates an invoice and returns a payment URL. That is useful for a fast agency implementation where the client does not need a custom payment UI.

The allows retrieving account payments with filters such as status, type, amount, date range, network, and pagination. This is important for backfills, reports, and support workflows.
