RabbyHub/Rabby MVP Feature Inventory

Reference repository inspected: https://github.com/rabbyHub/rabby at commit 69cd265.

This document records the feature/functionality classes Rabby Wallet exposes and treats them as the MVP target for this Rust/Tauri Rabby product. The current implementation keeps these as typed Rust models and unit-tested acceptance criteria first; runtime/UI implementation should then move feature-by-feature from Modeled to RuntimeImplemented.

MVP feature list

RabbyHub/Rabby architecture notes

RabbyHub/Rabby is a browser extension wallet with these major contexts:

• background: async requests, encryption, wallet/provider controllers, services.
• content-script: injected at document start, bridges dapps to background.
• pageProvider: injects window.ethereum and handles dapp requests.
• ui: notification, full tab, and popup views.

The Rust/Tauri version should map that to:

• rabby-core: wallet domain models and validation.
• rabby-runtime: persistence, keychain, network, and OS adapters.
• src-tauri: command/event boundary.
• ui: modern Rabby-like dashboard, approvals, settings, dapp requests.

Immediate product gap

The current app can open but is still a shell. The MVP work should prioritize:

1. Wallet onboarding/unlock state and local encrypted persistence.
2. Account import/watch-only flows.
3. Real portfolio dashboard state wired through Tauri.
4. Dapp permission and approval request UI.
5. Send/receive + swap/bridge request forms.
6. Settings/customization: theme, language, currency, auto-lock.

Unit test coverage added

rabby-core::wallet_mvp tests now assert:

• Every MVP feature class is represented.
• Feature keys are unique and documented.
• All Rabby account source types are covered.
• Account, chain, send, swap, and dapp permission validation works.
• Unsafe/incomplete wallet requests are rejected.
• Dashboard totals and high-risk approval counts are computed.
• Settings customization defaults validate.

Implemented runtime slices

• Encrypted local wallet dashboard vault: rabby-runtime::wallet_vault::EncryptedWalletVault writes AES-256-GCM encrypted JSON envelopes using Argon2id-derived keys, rejects blank/wrong passphrases, avoids plaintext wallet fields in storage, and is exposed to Tauri via save_demo_wallet_vault / load_wallet_vault.
