Spire

UnichainRegistered

Tracks per-address "horn length" (HORN token balance weighted by holding tenure) after each swap, accumulating reward weight for a UNI distribution system. Periodically harvests LP fees from a HORN/UNI pool to burn HORN and distribute UNI to holders proportionally; includes a "monarch" mechanic where the highest horn-length holder can claim a crown pot after a cooldown.
