[invoices]
; If a hold invoice has accepted htlcs that reach their expiry height and are
; not timed out, the channel holding the htlc is force closed to resolve the
; invoice's htlcs. To prevent force closes, lnd automatically cancels these
; invoices before they reach their expiry height.
;
; Hold expiry delta describes the number of blocks before expiry that these
; invoices should be canceled. Setting this value to 0 will ensure that hold
; invoices can be settled right up until their expiry height, but will result
; in the channel they are on being force closed if they are not resolved before
; expiry.
;
; Lnd goes to chain before the expiry for a htlc is reached so that there is
; time to resolve it on chain. This value needs to be greater than the
; DefaultIncomingBroadcastDelta set by lnd, otherwise the channel will be force
; closed anyway. A warning will be logged on startup if this value is not large
; enough to prevent force closes.
