Zcash NU7 upgrade could render remaining Sprout pool funds unspendable
Zcash plans to activate the NU7 network upgrade, which would reject all version‑4 transactions used by the legacy Sprout privacy pool. The Sprout pool still contains roughly 22,309 ZEC, and after activation holders would be unable to move those coins even with valid private keys. A final decision on main‑net activation is scheduled for Oct. 20, with Nov. 5 as the conditional target date. Migration to the newer Sapling pool is possible but requires users to act before activation.
Why it matters
The company warns that Sprout holders must migrate their funds to avoid losing the ability to spend them, which could affect ZEC liquidity and holder sentiment. The upgrade would keep the stranded coins in supply calculations but render them effectively unusable.
