Big props for diving into the Lightning-powered marketplace space #Nostr + Bitcoin is such a killer combo! Re: your question your total inbound liquidity (1.1M sats across channels) should work if the buyer’s wallet supports multi-path payments (MPP). No need to close existing channels! Pro tip: Test a small MPP transaction first. Also, bigger channels = less routing hops = happier buyers. Keep us posted – this is awesome!
