Lightning Labs opens Wavelength for autonomous AI agent payments on Bitcoin

The shift here is less about Lightning itself than about who initiates a payment: removing per-transaction human approval turns agent-to-agent commerce from a demo into an operating assumption, and the sub-cent economics are what make machine-scale API and data purchases viable at all. The self-custodial design with unilateral on-chain exits addresses the custody objection that has slowed institutional comfort with agent-held funds, though the Alpha label and the 300,000-sat wallet cap signal that risk tolerances are still being tested. Developers no longer needing to run a node or manage liquidity lowers the integration barrier considerably. The open question is whether agent-driven payment volume materializes before stablecoin support arrives, since most machine commerce is still priced in dollars.
