Questions & Answers

As answered by people managing CoinPayGateway and Diffyn.

What makes your product unique?

CoinPayGateway's answer

CoinPayGateway is non-custodial by design. Payments go straight from the customer's wallet to a wallet you control, so no one ever holds your money, there is no balance to freeze, and there are no chargebacks.

  • 0% transaction fees, with no percentage cut of any sale
  • No KYC and no application, you add your wallet and start selling
  • Supports BTC, ETH, USDT, USDC, LTC, SOL and XRP, with stablecoins on both Ethereum and Tron
  • HD wallets give every order its own receiving address
  • Built-in safety, including address-tampering protection and wallet-change alerts

Most gateways make you choose between control and convenience. This one gives you both.

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.

Why should a person choose your product over its competitors?

CoinPayGateway's answer

Most crypto gateways are custodial, which means they hold your money, can freeze it, and take a percentage of every sale. CoinPayGateway holds nothing and charges 0%, so you keep full control and every cent.

Compared to self-hosted options like BTCPay Server, you get the same non-custodial model without running your own node or server. Compared to hosted processors like Cryptomus or Coinbase Commerce, you keep custody of your funds and never pay a per-transaction fee. Setup takes minutes with no KYC.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Which are the primary technologies used for building your product?

CoinPayGateway's answer

  • PHP, as a native WordPress and WooCommerce plugin
  • JavaScript for the checkout and payment page
  • A REST API so any platform can integrate it
  • Server-side blockchain watching across Bitcoin, Ethereum, Tron, Solana and the XRP Ledger
  • BIP84 HD-wallet derivation for unique per-order addresses

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

CoinPayGateway's answer

Independent WooCommerce merchants who want to accept crypto without handing control to a processor. They care about keeping custody of their funds, avoiding KYC and paperwork, and not paying a cut on every sale. This includes sellers of digital goods, subscriptions and privacy-conscious stores, as well as merchants who are underserved or turned away by mainstream payment processors.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

CoinPayGateway's answer

It grew out of frustration with custodial crypto processors that held merchants' money, demanded KYC, and took a percentage of every sale. The goal was a gateway that does the opposite: settle payments straight to the merchant's own wallet, ask for no identity checks, and charge nothing per transaction. The result is a thin, non-custodial plugin backed by a service that watches the blockchain for you, offered free for small stores and with a flat yearly plan for larger ones.

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.
