Lightning Labs launches Ark-style Bitcoin payment platform Wavelength

Lightning Labs announced on the X platform that it has launched Wavelength, a self-hosted Bitcoin payment toolkit designed to make integrating Bitcoin into applications as simple as calling an API.

The platform is built on a layer similar to Ark, supporting developers, AI agents, and vibe coders to access Lightning payments for any application without the need to run nodes, manage channels, or acquire liquidity. It also supports AI agents using Bitcoin payment APIs, data sources, and other services through MCP tool calls. Wavelength is currently available in alpha version on signet and testnet, with mainnet access requiring an invitation.
