USDPAY is a crypto payment gateway that helps online businesses accept USDT payments directly on their websites.

Customers send USDT to the merchant’s own wallet. USDPAY monitors the blockchain, verifies the payment, and notifies the merchant’s website through an API or webhook. This allows the business to automatically activate a subscription, deliver a digital product, add account balance, or confirm an order after payment.

USDPAY is designed for SaaS products, online services, digital platforms, marketplaces, and other businesses that need automated crypto payment confirmation.

Key features:

  • USDT payments sent directly to the merchant’s wallet
  • Automatic blockchain payment verification
  • API and webhook integration
  • Support for TRON (TRC20), BNB Smart Chain (BEP20), and TON
  • No chargebacks
  • Suitable for subscriptions and digital products
  • No need to manually check incoming transactions

USDPAY does not hold or withdraw merchant funds. The service only verifies transactions and sends payment status updates to the connected website.

Questions & Answers

As answered by people managing USDPAY.me and Optim API.

What makes your product unique?

USDPAY.me's answer

USDPAY combines direct-to-wallet USDT payments with automatic payment verification. Funds are sent directly from the customer to the merchant’s own wallet, while USDPAY monitors the blockchain and notifies the merchant’s website through an API or signed webhook.

This allows online businesses to automate order confirmation, subscription activation, account balance updates, and digital product delivery without manually checking transactions.

Why should a person choose your product over its competitors?

USDPAY.me's answer

USDPAY is designed for businesses that want a simple way to accept USDT without transferring control of their funds to a payment provider.

Merchants receive payments directly to their own wallets, can integrate through a REST API or hosted checkout, and receive automatic payment status updates through signed webhooks. USDPAY supports USDT on TRON, BNB Smart Chain, and TON, making it suitable for customers using different networks.

There are no chargebacks, no forced conversion to fiat, and no need to manually verify incoming blockchain transactions.

How would you describe the primary audience of your product?

USDPAY.me's answer

USDPAY is primarily built for online businesses that sell digital products or provide services automatically after payment.

Typical users include SaaS products, subscription services, Telegram bots and Mini Apps, digital marketplaces, hosting and VPN services, online tools, educational platforms, and other businesses that need to confirm crypto payments through an API or webhook.

What's the story behind your product?

USDPAY.me's answer

USDPAY was created to solve a practical problem faced by online businesses accepting cryptocurrency.

Receiving USDT directly to a wallet is simple, but automatically identifying the correct payment, waiting for blockchain confirmation, updating an order, and delivering a service usually requires custom development.

USDPAY provides this missing automation layer. It monitors payments, verifies transactions, and sends payment status updates to the merchant’s system, while the funds remain in the merchant’s own wallet.

Which are the primary technologies used for building your product?

USDPAY.me's answer

USDPAY is built around blockchain transaction monitoring for TRON, BNB Smart Chain, and TON.

The platform uses blockchain APIs, a REST API, signed webhooks, hosted web checkout pages, and backend payment verification services to detect, confirm, and report USDT transactions to connected merchant systems.

Who are some of the biggest customers of your product?

USDPAY.me's answer

  • VidKeep.app — a browser-based video downloader and media tools service that uses USDPAY to accept USDT payments and automatically unlock paid access.
  • Gsim.me — travel eSIM service that uses USDPAY to accept USDT payments and automatically confirm customer orders.
