const LNV2_HOLD_INVOICE_CLTV_EXPIRY: u64 = 144;Expand description
Final CLTV delta of the HOLD invoices created for LNv2 receives. Left unset,
LND would use its routing bitcoin.timelockdelta, which operators may lower
to 24 (18 before v0.21), leaving only a few blocks between accepting a
payment and LND cancelling it by itself invoices.holdexpirydelta blocks
before expiry. LND rejects any HTLC expiring sooner than this many blocks
after it arrives, so it bounds every accepted HTLC, not just honest payers.
