Zcash started the week with liquidations hitting short-term bullish ZEC positions as traders faced fresh volatility. Joao Wedson said many long and short positions opened in recent days remained exposed, and that some longs held for up to six months had not yet been liquidated, leaving the market sensitive to another sharp move without a stated price target. Parallel to the positioning stress, the Zakura cryptography stack cut private transaction proof generation from more than three seconds to under 200 milliseconds in some cases, with reported gains of more than 14 times on mobile and more than five times on desktop. Zakura Common, an open-source toolkit released around August 31, targets wallet-side proof construction, scanning and verification so developers can adopt it without a hard fork or consensus change; Zakura, led by Zcash cofounder Sean Bowe with Dev Ojha, has moved its node software to the stack for release 1.3.0, with Vizor Wallet and Project Tachyon among early movers. Broader ecosystem work continued as Josh Swihart flagged Zodl Wallet 3.10.1 through 3.10.3 for Android and iOS, including Orchard balance handling after an Ironwood migration, public Zcash Android and Swift SDK 3.0.0 releases, and Zallet v0.1.0 beta 3 updates for PCZTs and security. The Zcash Foundation opened a ZCAP poll for NU7, and Grayscale launched a Zcash ETF. ZEC had climbed about 5% to near $839 after the Zakura release before pulling back with the wider market.
