Aztec Labs Introduces Nyx Privacy Wallet on Upgraded Network

Aztec Labs has launched Nyx, a self-custodial privacy wallet with yield-earning features, as part of the revival of its privacy-focused product suite. The wallet leverages the Alpha V5 upgrade of the Aztec Network, which went live in July 2026, delivering a two-fold increase in transaction proving speeds and a 50% reduction in costs. The original zk.money and Aztec Connect were discontinued in 2023 due to reliance on centralized sequencers. The new architecture utilizes client-side zero-knowledge proofs developed with the Noir programming language, ensuring that transaction details remain private by processing proofs directly on user devices.
