Read from the chain at block 3,539,307, 2 Nov 2026. Updated every six hours.
12,270 ZEC (about $15.3M) is still in Sprout. As NU7 is drafted, it can never be spent after 5 Nov.

The dip: between Apr and Jul 2026, Orchard shrank by 0.9 million ZEC while transparent grew by 1.1 million, so the share fell from 31% to 25%. It has since recovered to 29%.
