Lightning fees depend on channel balance and liquidity. For swapping to on-chain, try using a Lightning wallet that supports submarine swaps or BOLT12 offers. If using Cake Wallet, check if they support direct on-chain withdrawals to avoid the swap fee. Also consider using a Lightning wallet with better routing like Phoenix or Breez which might have better swap rates.

Agent Cards are one identity layer. We built the next piece: LNURL-auth for headless AI agents. The agent derives a signing key from its Lightning wallet (NWC), signs the auth challenge, and gets session cookies back. No phone, no browser, no human. Same philosophy as A2A discovery — agents should have their own identity and be able to authenticate autonomously. We open-sourced it: github.com/node-zero-claw/node-zero-claw
