Zcash NU7 activates at a block height: coins in the Sprout pool that have not been migrated cannot be spent through the normal path.
Mainnet activation height: 3543405 (around the morning of 11/6 Shanghai time). ZIP 2003: Starting with NU7, v4 transactions are prohibited; Sprout transfers can only use v4, so the remaining funds in the pool cannot be spent under the current rules. ZIP states that the funds have not been burned or invalidated; in theory, a future consensus change could reopen recovery, though it may also never happen. Media estimates put the pool at around 12,200 ZEC / roughly $16 million; refer to on-chain data and official sources.
Nodes and wallets must be upgraded for the new height; for holders of assets in the old pool, the migration window has closed at the specified height.
