USDT is designed to track the US dollar and is issued across multiple blockchain networks. For a business, this makes one technical detail especially important: accepting “USDT” is not enough. The payment flow must also specify the supported network and correctly match each incoming transfer to an order. Tether officially supports USDT across several blockchain protocols.

The broader business use of stablecoins is no longer marginal. McKinsey estimated B2B stablecoin payment activity at about $226 billion annually in 2026.

For industry context, it is useful to follow Raj Dhamodharan, executive vice president of Blockchain & Digital Assets at Mastercard. He works directly on blockchain payment and settlement infrastructure at one of the world’s largest payment networks, making his expertise particularly relevant to the business use of stablecoins.

Below are five practical ways to accept USDT online, ranked by the level of automation they provide.

1. Direct wallet transfer

The simplest option is to provide a wallet address or QR code and ask the customer to send USDT directly.

Pros: almost no integration work.

Limitations: the merchant must identify the payment, verify the network and amount, and connect the transaction to the correct order.

Best for: occasional B2B payments with manual reconciliation.

2. Payment link

A payment link creates a separate payment page that can be sent by email or messenger, or placed behind a button on a website. The payment parameters can be configured before the customer opens the page.

This is a practical middle ground when a business wants more structure than a wallet transfer but does not need a full checkout integration. For example, businesses can use a crypto payment link to create a payment request and track its status without building a custom integration.

Best for: invoices, consultations, custom orders and low-volume sales.

3. Embedded payment widget

A widget adds a crypto payment button or form directly to a website. It requires less development than a custom API connection while keeping the payment flow connected to the merchant’s site.

Best for: service websites, landing pages and smaller online businesses that need an embedded payment option without custom development.

4. CMS or e-commerce plugin

For stores built on a supported CMS, a ready-made plugin can add cryptocurrency as a checkout option and synchronize payment status with the order workflow.

This provides more automation than a wallet address or basic payment link while avoiding development of a payment system from scratch.

Best for: online stores using a CMS for which a compatible crypto payment module is available.

5. API-based crypto payment gateway

An API integration provides the highest level of control. A business can create payment requests programmatically, receive status updates and connect payment data with its own checkout or back-office logic.

A crypto payment processing platform can provide this infrastructure without requiring the merchant to build blockchain payment processing from zero. Cryptadium, for example, provides API-based processing alongside simpler integration methods.

Best for: marketplaces, high-volume stores, SaaS products and businesses with custom checkout logic.

Which method is best?

For most businesses, the five methods can be ranked by their typical level of automation:

  1. API — best for maximum automation and custom payment flows.
  2. CMS plugin — best for standard e-commerce stores.
  3. Widget — best for fast website integration.
  4. Payment link — best for invoices and individual orders.
  5. Direct wallet transfer — best when payment volume is low enough for manual control.

This ranking does not mean that an API is always the right choice. A payment link can be more efficient for a company processing ten individual invoices a month, while a store handling hundreds of orders needs automatic payment-status matching.

One rule applies to every method: define which USDT networks you support. Tether lists USDT on multiple protocols, including Ethereum, TRON, Solana and TON. A business therefore needs to make the supported network clear before a customer sends funds.

The best USDT payment setup is not necessarily the one with the most features. It is the one that matches payment volume, website architecture and the level of automation the business actually needs.
