Zavigator

Zavigator is a private-by-design Zcash explorer: the backend serves only public chain data, while the browser downloads encrypted transactions, decrypts them locally with a Unified Full Viewing Key (UFVK), and renders a personal finance–like dashboard. The viewing key never leaves the user’s device.

Quick start

pnpm install
pnpm dev

Visit http://localhost:3000 to confirm the WASM runtime spins up and the UI shell loads.

WASM workflow

1. Core logic lives in rust/crates/indexer/indexer-core.
2. rust/crates/web/wasm wraps it with wasm-bindgen and exports decrypt_history.
3. Run just wasm-build target=web whenever Rust changes; the generated package is imported via the @wasm/rust_wasm alias.
4. src/components/wasm-provider.tsx instantiates the module once per session and exposes decryptHistory, readiness state, and reload through useWasm().

Repository map

• src/ – Next.js app router, providers, and upcoming shielded UX.
• rust/crates/indexer – shared parsing/indexer logic.
• rust/crates/web/wasm – browser-facing bindings compiled with wasm-pack.

Future work focuses on wiring UFVK input, encrypted data retrieval, and decrypted history visualizations that stay entirely client-side.
