April 3, 2026 (UTC), Bitcoin.com News reported that the Linux Foundation has launched the x402 Foundation, a move to standardize how AI systems handle autonomous payments in both crypto and fiat currencies. Originally developed by Coinbase, the open-source x402 protocol allows AI programs to autonomously process payments using traditional currencies or cryptocurrencies. By overseeing this protocol, the Linux Foundation seeks to maintain a neutral standard and prevent any single entity from dominating its governance.

Major players in technology and finance—including Google, Microsoft, Amazon Web Services, Visa, Mastercard, American Express, and Circle—are backing the x402 initiative. Their involvement signifies industry-wide support to establish standardized processes for the emerging machine economy.

However, the adoption of the x402 protocol faces obstacles. Weekly transaction volumes, which peaked at over 13 million in November 2025, have plummeted in 2026 to between 29,000 and 1.1 million per week.

Competition in the autonomous AI payments sector is intensifying. Stripe and blockchain startup Tempo have collaborated to launch the Machine Payments Protocol, a competing system. Visa is contributing to this project, developing features specifically aimed at enabling AI agents to utilize credit and debit card payments.

Elsewhere, Mastercard is advancing its position by planning to acquire stablecoin infrastructure firm BVNK in a deal worth up to $1.8 billion. Former Binance CEO Changpeng Zhao has predicted that AI will eventually process payments at volumes one million times greater than human capability, with cryptocurrencies playing a central role. Meanwhile, BNB Chain unveiled new infrastructure for autonomous agent payments in February 2026.

As of April 3, 2026, 15:08 UTC, Ethereum (ETH) is trading at $2,055.19, with a -0.27% change in 24-hour trading volume, according to TradingView. Binance Coin (BNB) is valued at $588.26, showing a 2.24% increase. USD Coin (USDC) remains stable at $1, with a 0.01% fluctuation.
