JIT Channels (Just-In-Time)
Layer 2● Common

A technique where Lightning channels are opened on-demand when a payment arrives for a user without sufficient inbound liquidity. The LSP opens a channel funded with the incoming payment amount, often using zero-conf.

Technical Notes

LSPS2 defines standard. LSP wraps incoming payment, opens channel, forwards payment atomically. User receives minus channel open fee. Requires trust in LSP for zero-conf channel. Can use submarine swaps instead.
