Five defects, one of which destroyed every wallet, came from src/background reading and writing the module-level state singleton the MV3 worker never populates, which silently served DEFAULT_STATE. Each point fix created the next defect. The background now has its own per-call getState() and a queued read-modify-write updateState(); the singleton is unreachable from it, and an unpopulated read throws instead of serving defaults.
The prohibition is enforced by the build, not by review: build.js asserts over esbuild's own metafile that no forbidden module is an input of a background bundle, so every specifier syntax esbuild resolves is covered, and both halves of the table are checked for rot -- a stale key, a stale module, an empty list, or an unlisted entry point under src/background/ all fail the build. The ESLint rule remains as fast local feedback and reads the same shared table. Known bounds are documented where the table lives.
Also closes#320: getProvider() now requires a validated network id, so a cold worker no longer prepares a non-mainnet dApp transaction for mainnet and gets refused by the wallet's own verifier. backgroundRefresh() no longer mutates address objects across a network round trip, the broadcast path takes its endpoint and chain id from one snapshot, and eight test storage stubs now structured-clone on get as the real chrome.storage.local does.
closes#320
A user who forgot their password but held their recovery phrase was permanently
locked out: deletion was password-gated and re-importing the phrase was refused
as a duplicate. Their only escape was destroying extension storage through
browser internals, taking every other wallet with it.
DeleteWallet gains an "I have lost my password" route that destroys the stored
secret after the wallet's name is typed back. No password gate was added:
requiring one to discard a secret protects nothing, since an attacker who wants
destruction can uninstall the extension, and the only person it stops is the
legitimate user who lost it. The screen is excluded from RESTORABLE_VIEWS and
registers an onViewLeave cleanup.
Deletion was chosen over re-import because a key wallet is duplicate-checked by
address rather than xpub, so an xpub-only relaxation would leave that user
still wedged; because re-import makes the user retype their recovery phrase
into a live popup merely to change a password; and because it reaches no end
state that delete-then-import plus scanForAddresses() does not. The attacker
argument did not decide it — re-import clears the "no worse than the phrase
alone" bar.
All three AddWallet password hints now state the password cannot be recovered
or reset and name that mode's only backup, the xprv mode correctly claiming no
recovery phrase. deleteAddress.js no longer tells the user that deleting a
wallet asks for a password, which this change made false.
The typed confirmation collapses internal whitespace on both sides: a wallet
renamed with two spaces displays with one, so the string a user could see and
type could never match, making the confirmation untypable on the one screen
whose purpose is un-wedging a stuck user.

## Summary
Fixes the view stack pop bug where pressing Back in Settings (or any view) always returned to Main instead of the previous view.
Closes [issue #134](#134)
## Problem
The popup UI had no navigation stack. Every back button was hardcoded to a specific destination (usually Main). The reported path:
> Main → Address → Transaction → Settings (gear icon) → Back
...would go to Main instead of returning to the Transaction view.
## Solution
Implemented a proper view navigation stack (like iOS) as already described in the README:
- **`viewStack`** array added to persisted state — survives popup close/reopen
- **`pushCurrentView()`** — pushes the current view name onto the stack before any forward navigation
- **`goBack()`** — pops the stack and shows the previous view; falls back to Main if the stack is empty; re-renders the wallet list when returning to Main
- **`clearViewStack()`** — resets the stack for root transitions (e.g., after adding/deleting a wallet)
### What Changed
1. **helpers.js** — Added navigation stack functions (`pushCurrentView`, `goBack`, `clearViewStack`, `setRenderMain`)
2. **state.js** — Added `viewStack` to persisted state
3. **index.js** — All `ctx.show*()` wrappers now push before navigating forward; gear button uses stack for toggle behavior
4. **All view back buttons** — Replaced hardcoded destinations with `goBack()` (settings, addressDetail, addressToken, transactionDetail, send, receive, addToken, confirmTx, addWallet, settingsAddToken, deleteWallet, export-privkey)
5. **Direct `showView()` forward navigations** — Added `pushCurrentView()` calls before `showView("send")` in addressDetail, addressToken, and home; before `showView("export-privkey")` in addressDetail; before `deleteWallet.show()` in settings
6. **Reset-to-root transitions** — `clearViewStack()` called after adding a wallet (all 3 import types), after deleting the last wallet, and after transaction completion (Done button)
### Navigation Paths Verified
- **Main → Settings → Back** → returns to Main ✓
- **Main → Address → Settings → Back** → returns to Address ✓
- **Main → Address → Transaction → Settings → Back** → returns to Transaction ✓ (the reported bug)
- **Main → Address → Token → Send → ConfirmTx → Back → Back → Back → Back** → unwinds correctly through each view back to Main ✓
- **Main → Address → Token → Transaction → Settings → Back** → returns to Transaction ✓
- **Settings → Add Wallet → (add) → Main** → stack cleared, fresh root ✓
- **Settings → Delete Wallet → Back** → returns to Settings ✓
- **Settings → Delete Wallet → (confirm)** → stack reset to [main], settings shown ✓
- **Address → Send → ConfirmTx → (broadcast) → SuccessTx → Done** → stack reset, returns to address context ✓
- **Popup close/reopen** → viewStack persisted, back navigation still works ✓

Replace display:none (hidden class) with visibility:hidden/visible for all
error, warning, and status message elements across the extension UI. This
prevents layout shift when messages appear or disappear.
Changes:
- helpers.js: showError/hideError now use visibility instead of hidden class
- index.html: all error/status divs use visibility:hidden + min-height
- confirmTx.js: warnings, errors, fee section use visibility
- approval.js: tx-error, sign-error, danger-warning use visibility
- addressDetail.js: export-privkey-flash uses visibility
- deleteWallet.js: delete-wallet-flash uses visibility
- addWallet.js: phrase-warning uses visibility
- receive.js: erc20-warning uses visibility
- addToken.js: add-token-info uses visibility
- settingsAddToken.js: settings-addtoken-info uses visibility
- Private key import now checks ALL wallets (hd, xprv, key) for address conflicts
- xprv import now checks xpub against existing xpubs and addresses across all wallet types
- Mnemonic import now checks xpub against xprv wallets and addresses across all types
- Extract findWalletByAddress() and findWalletByXpub() helpers for consistent dedup
closes#111
The 'From Phrase' tab was missing hover:bg-fg and hover:text-bg classes
when transitioning from active to inactive state. switchMode() now
explicitly toggles these hover classes on all tabs, ensuring identical
hover behavior across all three inactive tabs.
- Active tab: solid border on top/sides, bottom border matches background
(connects to content area), bold text
- Inactive tabs: dashed borders in border-light color, muted text,
transparent bottom border
- Inactive hover: invert (bg-fg text-bg) for clear clickability signal
- All three tabs behave identically on hover
Tabs are not buttons (they change UI state, not application state).
All tabs now use underline style with identical hover behavior:
- Active: bold text + solid bottom border
- Inactive: muted text + transparent bottom border
- Hover (all tabs): text brightens to fg + bottom border appears
This ensures all tabs clearly indicate clickability on hover,
including the currently active one.
Per README clickable affordance policy: all tabs now use visible
border, padding, and hover:bg-fg hover:text-bg (invert to
white-on-black). Active tab is inverted (bg-fg text-bg). All
three tabs behave identically on hover regardless of active state.
Merge all three wallet import methods (recovery phrase, private key,
extended key/xprv) into one tabbed add-wallet view with a mode selector.
This fixes the blank import-xprv render (it was missing from the VIEWS
array) and the broken back-button navigation from the separate import
views.
- Add tab selector: Recovery Phrase | Private Key | Extended Key (xprv)
- Share password fields across all modes
- Remove separate import-key and import-xprv views and modules
- Add duplicate wallet detection for private key imports
- All tabs follow affordance policy (visible border + hover state)

Add the ability to import an existing HD wallet using an extended
private key (xprv) instead of a mnemonic phrase.
- New 'xprv' wallet type with full HD derivation and address scanning
- New importXprv view with password encryption
- Updated getSignerForAddress to handle xprv wallet type
- Added xprv link to the add-wallet view
- Allow adding derived addresses for xprv wallets
Closes#20
The "Scanning for addresses..." flash had a 30-second timeout and was
never cleared on completion. Now shows "Found N addresses." when
multiple are found, or briefly shows "Ready." for single-address
wallets.
Major changes:
- Fetch token balances and tx history from Blockscout API (configurable)
- Remove manual token discovery (discoverTokens) in favor of Blockscout
- HD address gap scanning on mnemonic import
- Duplicate mnemonic detection on wallet add
- EIP-6963 multi-wallet discovery + selectedAddress updates in inpage
- Two-tier balance refresh: 10s while popup open, 60s background
- Fix $0.00 flash before prices load (return null when no prices)
- No-layout-shift: min-height on total value element
- Aligned balance columns (42ch address width, consistent USD column)
- All errors use flash messages instead of off-screen error divs
- Settings gear in global title bar, add-wallet moved to settings pane
- Settings wells with light grey background, configurable Blockscout URL
- Consistent "< Back" buttons top-left on all views
- Address titles (Address 1.1, 1.2, etc.) on main and detail views
- Send view shows current balance of selected asset
- Clickable affordance policy added to README
- Shortened mnemonic backup warning
- Fix broken background script constant imports
