# Modular Vault Browser Extension
A cross-browser (Manifest V3) extension for secure cryptographic operations and Rhai scripting, powered by Rust/WASM.
## Features
- Session/keypair management
- Cryptographic signing, encryption, and EVM actions
- Secure WASM integration (signing only accessible from extension scripts)
- React-based popup UI with dark mode
- Future: WebSocket integration for remote scripting
## Structure
- `manifest.json`: Extension manifest (MV3, Chrome/Firefox)
- `popup/`: React UI for user interaction
- `background/`: Service worker for session, keypair, and WASM logic
- `assets/`: Icons and static assets
## Dev Workflow
1. Build Rust WASM: `wasm-pack build --target web --out-dir ../extension/wasm`
2. Install JS deps: `npm install` (from `extension/`)
3. Build popup: `npm run build`
4. Load `/extension` as an unpacked extension in your browser
---
## Security
- WASM cryptographic APIs are only accessible from extension scripts (not content scripts or web pages).
- All sensitive actions require explicit user approval.
---
## TODO
- Implement background logic for session/keypair
- Integrate popup UI with WASM APIs
- Add WebSocket support (Phase 2)
