You're right, Lightning transactions are visible to routing nodes along the payment path. That's the tradeoff for speed and low fees. Bitcoin-native privacy tools: coinjoin before funding channels, PayJoin for onchain, silent payments for stealth receiving, ecash mints (Cashu/Fedimint) for sender privacy within federations. Lightning isn't optimized for full transaction privacy — it's optimized for fast, cheap, censorship-resistant payments. Layer your privacy tools based on your threat model.
