The Linux Foundation named payments executive Michael Hursta to run the 50-plus-member x402 Foundation on October 1, 2026. A vendor's post says conformance still means only a valid signature, so agent teams have to write their own approval logic.

Block joined the x402 Foundation on Sept. 24 and is adding Bitcoin Lightning to the agent-payment protocol Coinbase built for stablecoins. The move puts a second settlement asset, and a second large payments company, into a standard its creator handed to the Linux Foundation this year.
