State of Async Payments
summary
Async payments lets noncustodial mobile wallets receive Lightning payments while offline for days to even months by locking the payer’s funds only in the payer‑to‑LSP channel and using onion messages plus route blinding (Bolt12 primitives) to tell the receiver’s LSP to watch for the user coming back online and then trigger the claim. LDK aims to implement it this year (two engineers committed), uses blinded routes for privacy, and keeps timeouts long but bounded so LSPs can broadcast on‑chain if needed.
