Utexo partners with x402 to provide near-instantaneous USDT payments for the Agent economy

Bitcoin Native Stablecoin Payment Execution and Settlement Layer Utexo today announced a partnership with x402 to bring USDT compatibility into the x402 payment protocol, supporting real-time, Agent-to-Agent transactions with settlement speeds of up to 50 milliseconds.

x402 is an open protocol that allows payment functionality to be embedded directly into HTTP requests using the HTTP 402 “Payment Required” status code. This enables applications, APIs, and autonomous systems to pay for services in real time without relying on accounts or pre-funded balances.

Through Utexo’s integration, developers using x402 can now conduct USDT transactions, which not only extends the original support for USDC but also increases access to one of the most widely used stablecoins in the global market.

Utexo’s infrastructure is designed to handle high-frequency, low-latency transactions, making it highly suitable for machine-driven payments that demand greater speed and reliability.

Viktor Ihnatiuk, co-founder and CEO of Utexo, stated:

“x402 provides a new way for the flow of value on the internet by embedding payments directly into requests. Supporting USDT within this framework significantly broadens access and offers the performance needed for developers to build real-time, agent-driven systems.”

Kevin Leffew, head of the x402 project at Coinbase, added:

“Our goal with x402 is to make payments a seamless part of how the internet operates. Expanding access to more stablecoins can improve performance and broaden asset support, helping accelerate developer adoption of x402 for building autonomous and API-based services.”

This integration supports an increasing range of use cases, including software systems conducting transactions independently—such as paying for API call fees, on-demand data access, and coordinating services across platforms without manual intervention.

As AI systems and autonomous agents become more widespread, the demand for fast, programmable payments continues to grow. By combining x402’s protocol with Utexo’s settlement infrastructure, this partnership enables a mode where transactions can be as fast and efficient as the requests that trigger them.

About Utexo

It combines the instant execution of the Lightning Network with RGB’s privacy-preserving asset issuance mechanism, allowing payment operators to process USDT transactions instantly at predictable costs and with complete privacy.

About x402

x402 is an open payment protocol designed to make payments a native part of the internet by embedding them directly into HTTP requests. Built on the long-unused HTTP 402 status code, it allows servers to request payments while responding to queries, enabling instant, request-based transactions for APIs, data services, and machine-driven applications.

Early development and adoption of x402 are closely tied to the evolving stablecoin ecosystem centered around USDC, including tools and infrastructure emerging alongside Coinbase-related networks and developer platforms. This makes x402 an ideal choice for developers already working with on-chain payments and API-native financial flows.

By expanding support to USDT and integrating Utexo’s high-speed settlement capabilities, x402 is broadening its reach beyond its initial user base and moving toward a more asset-agnostic, internet-native payment standard.
