Episode notes
Lightning Labs built Wavelength to deliver self-custodial Lightning payments without forcing users to run nodes, manage channels, or handle liquidity.
Olaoluwa Osuntokun, CTO and co-founder of Lightning Labs, and Michael Levin, VP of Product, join me to detail the design choices behind their Ark implementation.
They explain why Ark was selected, how hop hints let every payment use ordinary Lightning invoices, and why the four-endpoint SDK targets AI agents and vibe coders. The conversation covers sub-dust vouchers, unilateral exits, offline payment delivery, and one-basis-point alpha pricing.
Wavelength shows that self-custodial Lightning can match the integration ease of custodial services while preserving Bitcoin sovereignty.
