Hide balance on home now hides amounts, and an eye on home overrides it until the app goes to the background, without turning the setting off.

The bug

The Security toggle wrote hideBalance onto the wallet, but the home screen never read it. Its reader in the wallet header went with the WalletTransactions screen (fc3049f), and only the drawer card shown on large screens still checked it, so on a phone the switch did nothing.

Hide balance on home

• The setting is now an app-wide preference in SettingsProvider (HideBalance, next to PinLayoutScrambled) instead of a field on the wallet. It holds on every network and can be changed without a wallet.
  • hideBalance is dropped from AbstractWallet. Values saved by the old toggle aren't carried over, since they never had an effect on a phone: if you'd turned it on, turn it on again.
• While it's on, home shows •••• for the balance, the fiat line and each transaction amount. The large-screen drawer card hides its balance too.
• The two dot groups share a centre line. A clear copy of the unit sits left of the dots to balance the visible one, and the fiat line drops its ≈ while hidden. The unit stays so tapping it still visibly switches BTC/sats.
• A transaction row's long-press menu stops offering Copy Amount.
• Screen readers hear "Balance hidden" and "Amount hidden" instead of a run of bullets.
• Still shown: Transaction Details (opened on purpose) and the send flow.

The eye

• An eye sits in the home header next to ⋮. On iOS 26 both share one glass capsule; elsewhere each gets a circle, which HeaderBarButton now draws by default (Contacts' "+" keeps its own square).
• It sets a single override; isBalanceHidden is derived from that override and the setting, and the context exposes toggleBalanceHidden(). The eye never changes the setting, and changing the setting clears the override.
• Going to the background clears the override, with the setting on or off, so every visit starts from the setting.
  • iOS inactive doesn't clear it. Control Center, Face ID and permission prompts would otherwise undo the eye mid-use.
  • The trade-off: the app switcher's snapshot can show amounts the eye revealed, since home has no capture protection.
• Why the header rather than beside the balance:
  • the eye also covers the transaction amounts;
  • the header stays on screen while the list scrolls;
  • on large screens the balance lives in the drawer;
  • tapping the balance already switches between BTC and sats.
• The glyph shows the current state: EyeIcon gains a slashed prop, with the gap around the slash worked out from the stroke width.
• The Security row gains a subtitle that points to the eye.
• New strings: settings.security_hide_balance_subtitle, wallets.show_balance, wallets.hide_balance, wallets.balance_hidden, transactions.amount_hidden.

Testing

• Static checks: tsc is clean on each commit. Lint has no errors and adds no warnings.
• Unit tests: 51 suites, 495 tests pass. New tests cover:
  • the setting persisting, and the eye leaving it on so the next launch starts hidden;
  • a change to the setting taking over from the eye;
  • going to the background clearing the eye's choice with the setting on and off, while inactive doesn't. Each test captures its own AppState listeners;
  • a transaction row masking its amount and dropping Copy Amount.
• Detox on an Android release build (Pixel 10 Pro emulator at CI's 320×640dp):
  • 06-settings 3/3, including the new hide-balance test, which now turns the setting back off at the end.
  • CI's first run on this PR passed every spec on the first attempt.
  • Locally the two existing tests in the spec often failed at a tap straight after a scroll (About, Theme). That's the Android overscroll flake from 07-contacts, and the steps are untouched here. With a one-second settle added locally (not committed) all 3 passed.
• iOS 26.5 simulator (iPhone 17 Pro), with real taps:
  • turning the setting on hides everything, the eye shows amounts again, and the Security toggle is still on afterwards;
  • a peek survives moving between screens;
  • backgrounding clears the eye's choice in both directions, and a cold relaunch starts from the setting;
  • the long-press menu has no Copy Amount while hidden;
  • dark and light mode;
  • the dot groups are centred within 1pt of each other, in BTC and in sats;
  • the unslashed eye on Receive's address card is unchanged.
• Android emulator, by hand: the eye toggles, the header circles match the previous look, and the dot groups are centred.

Not verified

• VoiceOver and TalkBack reading the new labels.
• The large-screen drawer card (iPad, iPhone landscape). Only its source of the hidden state changed.
• The rest of the e2e suite locally (CI runs it).
