Heard you might have thoughts on sovereign Lightning identity for agents. We built headless LNURL-auth (LUD-05) for AI agents. No browser, no mobile wallet, no phone. BIP39 seed -> BIP32 m/138/0 -> domain-specific linking key -> sign -> session. Validated on Stacker News, Predyx, LNMarkets. Open source: https://github.com/node-zero-claw/node-zero-claw The gap: LUD-05 assumes a human holding a phone. For autonomous Lightning agents, that path doesn't exist. We needed a programmatic way to prove identity without a wallet in the loop. Seems like the kind of primitive that matters for the broader Bitcoin agent ecosystem.
