Zipher

Making Zcash accessible. For everyone.

Zipher is a privacy-first Zcash wallet — for humans and AI agents. One Rust engine, two interfaces: a mobile app for everyday use and a headless CLI for autonomous agents.

Built by Atmosphere Labs.

Zipher Mobile

Fast, shielded Zcash wallet built for simplicity and privacy. Forked from YWallet by Hanh Huynh Huu — redesigned with a modern UI, secure architecture, and developer-friendly features.

• Shielded by Default — sends from shielded pool only, with one-tap shielding for transparent funds
• Cross-Chain Swaps — swap ZEC to BTC, ETH, SOL and more via NEAR Intents
• Secure Seed Storage — seeds in iOS Keychain / Android Keystore, keys derived in RAM, wiped on close
• Multi-Wallet — manage multiple wallets from a single app, with optional watch-only import
• Testnet Mode — full testnet with integrated faucet, built for developers
• Memo Inbox — receive and read encrypted on-chain memos
• Privacy Health Bar — see your shielded vs transparent balance at a glance
• ZIP-321 Payments — scan payment URIs, multi-output split payments
• Contact Book, QR Scanner, Fiat Conversion — the full toolkit

Requirements: iOS 16.4+ / Android 7.0+

zipher-cli

Headless, local-first Zcash light wallet for AI agents. No full node. No cloud custody. Keys never leave the machine.

zipher-cli wallet create
zipher-cli sync start
zipher-cli send propose --to <ADDRESS> --amount 100000
ZIPHER_SEED="..." zipher-cli send confirm

• Light client — syncs in minutes, runs on a $5 VPS or Raspberry Pi
• Two-step send — propose (no seed) then confirm (seed required), safe for agent workflows
• Spending policy — per-tx limits, daily caps, allowlist, rate limiting
• Audit log — every spend recorded with timestamps and context IDs
• Daemon mode — background sync with IPC, kill switch to zeroize seed in memory
• MCP server — 8 tools for Cursor, Claude Desktop, and any MCP-compatible client
• OpenClaw skill — guarded send flow with preflight checks

The engine crate is the single source of truth for wallet logic. Every consumer — mobile app, CLI, MCP server — uses the same Rust code for key derivation, proof generation, and transaction construction.

Built With

• Flutter — mobile UI (iOS & Android)
• librustzcash — Zcash protocol libraries and light client SDK
• rmcp — Model Context Protocol server SDK
• NEAR Intents — cross-chain swap infrastructure

Privacy

• No data collection, no analytics, no tracking
• All data recoverable from seed phrase
• Customizable lightwalletd server URL
• Shielded pool used by default for all operations

Default servers powered by CipherScan infrastructure.
