Lightning Service Providers

What does an LSP do when it sets up a just-in-time channel for you?

• It sends you an on-chain payment that you later move into a channel
• It opens a channel to your wallet when your first payment arrives and takes its fee from that payment
• It holds your first payment in an account until you open a channel yourself

Your wallet's LSP is your only channel peer. Which of these can it see?

• Nothing, because Lightning payments are onion-routed
• The amount and timing of every payment that passes through it
• Only payments larger than its minimum fee
