Utexo, a Bitcoin-native stablecoin payment execution and settlement layer, today announced a partnership with x402 to integrate USDT compatibility into the x402 payment protocol, supporting real-time, agent-to-agent transactions with settlement speeds as fast as 50 milliseconds.
x402 is an open protocol that enables payment functionality to be directly embedded into HTTP requests using the HTTP 402 "Payment Required" status code. This allows applications, APIs, and autonomous systems to pay for services in real-time without relying on accounts or pre-funded balances.
With Utexo's integration, developers using x402 can now conduct USDT transactions, expanding beyond the initial support for USDC and increasing 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 well-suited for machine-driven payments that demand higher speed and reliability.
Viktor Ihnatiuk, Co-founder and CEO of Utexo, stated:
"x402 offers a new way for value to flow across the internet by embedding payments directly into requests. Supporting USDT within this framework significantly expands access and provides developers with the performance needed to build real-time, agent-driven systems."
Kevin Leffew, Lead for 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 improves performance and broadens asset support, which helps accelerate developer adoption of x402 for building autonomous and API-based services."
The integration supports a growing range of use cases where software systems transact independently, including paying for API calls, accessing data on-demand, and coordinating services across platforms without human intervention.
As AI systems and autonomous agents become more widely deployed, the need for fast, programmable payments continues to grow. By combining x402's protocol with Utexo's settlement infrastructure, this partnership enables a model where transactions can be as fast and efficient as the requests that trigger them.

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. Based on the long-unused HTTP 402 status code, the protocol allows servers to request payment when responding to queries, enabling instant, per-request transactions for APIs, data services, and machine-driven applications.
The early development and adoption of x402 have been closely tied to the evolving stablecoin ecosystem around USDC, including tools and infrastructure emerging alongside Coinbase-related networks and developer platforms. This has made x402 an ideal choice for developers already working with on-chain payments and API-native financial flows.
By expanding support for 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.
