As answered by people managing MakePay and Diffyn.
MakePay's answer
MakePay is built around direct self-custody settlement instead of holding merchant funds. Businesses can accept major cryptocurrencies through hosted payment links, embedded checkout, subscriptions, POS flows, webhooks, APIs, and official plugins while receiving payments directly to their own wallet.
That combination makes it practical for merchants that want crypto checkout without building payment infrastructure from scratch, and without relying on a custodial processor for settlement.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
MakePay's answer
MakePay combines merchant-friendly crypto checkout with direct self-custody settlement, broad platform coverage, and simple integration options. Merchants can use branded payment links, embedded checkout, subscriptions, POS flows, signed webhooks, APIs, and plugins without building their own payment gateway.
It is especially useful for businesses that want crypto payments to settle into their own wallet, and that want 0% merchant fees by default when customers cover the payment fee.

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
MakePay's answer
MakePay was created to make crypto payments usable for everyday merchants, not only developers or crypto-native teams. The product focuses on the practical pieces a business needs: checkout, payment links, wallet settlement, payment status tracking, webhooks, APIs, and ready-made plugins.
The goal is to let merchants add crypto as a payment option quickly while keeping control of their own funds through self-custody settlement.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
