Block Brings Bitcoin Lightning Support to x402 Payment Protocol

Block has joined forces with the x402 Foundation to bring Bitcoin Lightning payments to its payment protocol. This expansion aims to enable low-cost, high-volume transactions that are expected in agentic commerce.

The addition of Lightning support will help make Bitcoin a more viable option for everyday use, especially for AI agents and web services that rely on API access, data, and digital services.

According to Steve Lee, head of Block's Bitcoin development initiative Spiral, 'Bringing Lightning to x402 is a concrete step toward making Bitcoin everyday money for people and the agents acting on their behalf.'

This move builds on Block's participation in the Universal Commerce Protocol, an effort to enable AI-driven commerce for small businesses.
