lightning-decode -- Command for decoding an invoice string (low-level) ======================================================================= SYNOPSIS -------- **decode** *string* DESCRIPTION ----------- The **decode** RPC command checks and parses: - a *bolt11* or *bolt12* string (optionally prefixed by `lightning:` or `LIGHTNING:`) as specified by the BOLT 11 and BOLT 12 specifications. - a *rune* as created by lightning-commando-rune(7). It may decode other formats in future.
