developer-tools // SDKs
Early-stage Lightning Labs toolkit for self-custodial Bitcoin payments in apps and AI agents, built on Ark.
Build: Agent Payments
overview
Wavelength combines an Ark client, a Lightning swap engine, and an on-chain wallet behind one daemon with gRPC and REST APIs, plus Go and TypeScript SDKs and an MCP server for AI agents. Users keep sole custody and can exit to the chain at any time. It's young (v0.2, October 2026), so expect APIs to change.
