Headline: Zcash launches Zillions browser wallet — Anoma-powered, Ledger support, shielded transfers and fast client-side proving
Zcash unveiled Zillions on Oct. 27, a browser-based wallet built with Anoma technology that aims to make shielded ZEC accessible to mainstream users. The launch brings a no-install web app, a companion Keychain extension for multi-account management, and hardware-wallet support — Ledger compatibility is available at launch, with Keystone integration slated to follow the week after.
What Zillions brings
- Dual-mode balances: Zillions supports both transparent and shielded transfers and displays separate balances for each. The UI labels transaction types and offers a shielded-transfer option at send time.
- Easy onboarding: The wallet team says the browser application is designed for users without prior Zcash experience. It runs without installation in Chrome, Firefox, Brave and other Chromium-based browsers, and handles account syncing and transaction proving within the wallet software.
- Multi-account Keychain: A separate Zillions Keychain browser extension creates, imports and manages multiple Zcash accounts or seed phrases, letting users switch accounts inside the web app. The extension also coordinates signing while keeping keys isolated from the web page.
Security and UX design
Zillions’ architecture emphasizes sandboxing and minimal device access: the team says the app does not require root or administrator permissions and can run without access to local files or control over the rest of the device. Proof generation and transaction preparation happen client-side, with multicore proving used to speed up proof creation — an approach intended to deliver near-instant payments while keeping private data on the user’s device.
Ledger (and Keystone soon)
Hardware support starts with Ledger: users select an account in the wallet UI, verify outgoing transactions on their Ledger device and sign from there. Keystone compatibility was announced as coming the week after launch, with Ledger compatibility shipped in version one.
Syncing and performance
Zillions uses a “Shielded Sync” system for account synchronization. The team reports syncing older accounts in under 30 seconds on a lightweight laptop with a regular internet connection and says it continues working to shorten sync times further. The wallet’s client-side proving performance is aided by multicore proof generation.
Broader performance context
Zillions’ launch follows recent Zcash performance work. On Aug. 29, Zakura published open-source cryptography libraries and developer benchmarks showing transaction-preparation times below 200 milliseconds in many cases. Zakura reported mobile proof generation more than 14× faster and desktop proof generation more than 5× faster, with libraries released under MIT and Apache 2.0 licenses and not requiring a network upgrade.
Network upgrade timeline
The Zcash Foundation shipped Zebra 7.0.0 on Oct. 22, confirming support for NU7, which is scheduled to activate at mainnet block 3,543,405 — around Nov. 5. The upgrade will shorten target block spacing from 75 seconds to 25 seconds; daily ZEC issuance will remain unchanged because rewards per block will be divided by three. Node operators must upgrade before activation to remain on the consensus chain.
Anoma and Zconnect background
Anoma’s research forum had earlier documented work on browser-wallet connections. A July 23 proposal for “Zconnect” described an interface by which web apps could request signing operations from wallet extensions; it named Zillions as the first candidate application and the Keychain extension as an initial implementer. That proposal also discussed passing partially created Zcash transactions (PCZTx) between participants, including hardware-wallet signers, while leaving proof construction to web applications.
How Zillions fits the wallet landscape
Zillions joins other Zcash wallets such as Zodl (formerly Zashi), a self-custody mobile option that rebranded in February and supports transparent-to-shield flows, Keystone hardware integration and CrossPay payments. Zodl has also been running a macOS Vault waitlist for long-term self-custody and a desktop beta with staged invite groups.
Next steps
Zillions’ team invited users to try the web app, explore features and share feedback following the Oct. 27 announcement. With Ledger support live, Keystone imminent, client-side proving, and a focus on accessibility and sandboxed security, Zillions looks aimed at lowering the barrier to shielded ZEC for everyday users while integrating with the wider Zcash upgrade and tooling ecosystem.
