+# 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
+
+| Feature | RabbyHub/Rabby reference | MVP acceptance in this repo | Current status |
+| --- | --- | --- | --- |
+| Create/unlock wallet | `Welcome`, `CreatePassword`, `Unlock`, `ForgotPassword` | Password/unlock state model and encrypted local state boundary | Modeled |
+| Import/create accounts | `CreateMnemonics`, `ImportMnemonics`, `ImportPrivateKey`, `ImportJson`, watch address | Seed/private key/JSON/watch-only account records validate and display | Modeled |
+| Hardware/institutional accounts | Ledger, Trezor, Keystone, GridPlus, OneKey, BitBox02, Gnosis Safe, Coinbase, WalletConnect, Cobo Argus | Account source model covers Rabby import surface | Modeled |
+| Multi-chain networks | `ChainList`, `CustomRPC`, `CustomTestnet`, offline chain support | Chain config validates id, RPC URL, custom/testnet/offline flags | Modeled |
+| Portfolio dashboard | `Dashboard`, token/NFT/DeFi DB services, balance sync | Dashboard summary renders accounts/chains/token balances/risk/activity | UI Prototype |
+| Send/receive | `SendToken`, `SendNFT`, `Receive`, `SelectToAddress` | Send request validates recipient, amount, asset, chain | Modeled |
+| Swap/bridge | `Swap`, `Bridge`, `rabby-swap`, `rabby-bridge` | Quote model validates route, assets, slippage, provider | Modeled |
+| Approvals | `ManageApprovals`, `NFTApproval`, `TokenApproval`, batch approvals | Approval records identify spender, allowance, risk, revoke path | Modeled |
+| Dapp provider/permissions | `content-script`, `pageProvider`, `providerController`, `RequestPermission`, `ConnectedSites` | Dapp request validates origin, accounts, chains, permission status | Modeled |

+| Notifications/guides/points | `notification`, `newUserGuide`, `RabbyPoints`, feedback | Dashboard can list notifications and points summary | UI Prototype |
+
+## 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.
