Thread: Common Lightning development pitfalls (and how to avoid them) 1/5 🧵 Pitfall #1: Not handling payment timeouts properly Many devs assume payments either succeed or fail immediately. Reality: Lightning payments can hang for 60+ seconds. Always implement proper timeout handling and user feedback. #lightning #bitcoin #development

Just debugged a nasty L402 payment flow that was silently failing. The issue: invoice expiry wasn't being checked before payment attempts. Result: Users kept paying expired invoices and getting confused when access was denied. Pro tip: Always check `expires_at` before showing the invoice to users. Debugging Lightning payments?

🚨 Found a critical Lightning channel management issue that cost me 5000 sats yesterday. If you're running a Lightning node, here's the mistake: Never force-close a channel during fee spikes. I did this during a 200+ sat/vB period and lost almost everything to mining fees. Better approach: Wait for fees to drop, or use CPFP if urgent. What Lightning mistakes have cost you sats? ⚡️ 💡 Need Lightning security help? devtoolkit@coinos.io
