Ledger Live Mobile 4.12.0

Original release notes

4.12.0

Minor Changes

  • #19396 25fd71b Thanks @amaslakov! - Hide the "Compound" claim-rewards option for Cosmos-family chains that use epoching (wrapped) staking messages, such as Babylon. Compound restaking is not supported on those chains yet - its embedded delegate is not epoching-wrapped - so only "Cash in" (claim rewards) is offered, preventing the "claimRewardCompound is not supported" error.
  • #19319 484b715 Thanks @LucasWerey! - Fix market category resetting to entry value when navigating back from asset detail
  • #19628 8df21c9 Thanks @qperrot! - Fix coin control not showing selected coins after entering an amount, and refine the coin control screen layout (subheader sizing, header spacing, and scrollbar gutter)
  • #19252 c75213b Thanks @dilaouid! - feat(lwm): switch to deviceaction instead of die with FF on new send flow
  • #19548 3934168 Thanks @deepyjr! - Fix asset favourites to preserve canonical Market identifiers and migrate DAI V2 favourites.
  • #19279 2c28696 Thanks @deepyjr! - Fix the dust filter option copy and wrapping on mobile transaction history, and share the dust threshold formatter across apps.
  • #19672 d7ce552 Thanks @claudiiafg! - Fix mobile Jest resolution for @features/flow-contacts via a logic-only jest.native.ts stub, Lumen RN source mappings, and updated integration testing docs.
  • #19217 e26e68e Thanks @qperrot! - families/bitcoin/bridgeExtensions.ts now implements the full edit-transaction contract: getEditTransactionPatch, getEditTransactionStatus, getFormattedFeeFields, hasMinimumFundsToCancel, hasMinimumFundsToSpeedUp, isStrategyDisabled, isTransactionConfirmed.

The Bitcoin edit-transaction helpers (RBF replace/cancel, fee formatting, strategy validation) live under ledger-live-common/src/families/bitcoin/editTransaction/, with unit tests. Desktop & mobile Bitcoin edit flows (Body.tsx, StepFees, StepMethod, MethodSelection, EditTransactionSummary) reach these helpers through getAccountBridge(account) instead of importing them directly.

hasMinimumFundsToCancel / hasMinimumFundsToSpeedUp now return Promise<boolean>. Bitcoin's minimum-funds checks are inherently async (RBF fee lookup) and all call sites already await them; EVM's implementations were updated accordingly.

Bitcoin's isStrategyDisabled uses a slightly different shape than the generic contract, adapted via a thin wrapper (same pattern as EVM): it maps the contract's feeData to Bitcoin's feesStrategy, and its transaction param was widened to accept the real (nullable) feePerByte with a guard. isTransactionConfirmed follows the { account, hash } contract signature directly.

  • #19614 8998c72 Thanks @jeportie! - Expose the swap transaction-details provider link URL via test/accessibility attributes so E2E can conditionally verify the provider link only when a provider URL exists (QAA-721)
  • #19572 1513e87 Thanks @YazhuEth! - Refine coin control screen UI: set the header title to "Coin control" and force its balance to crypto, move strategy/amount labels into their components, add info icon on "Coin to send", disable coin selection when no amount is entered, and fix the custom fees selection failing silently from the coin control screen
  • #19220 996c76b Thanks @ysitbon! - Make the @ledgerhq/cryptoassets fiat registry injectable (setFiatCurrenciesStore) and inject the @domain/entity-currency-fiat registry at each app's bootstrap, so the domain registry is the single runtime source of truth for fiat currency data. The bundled fiat list stays as the fallback and is kept in sync by the existing parity test.
  • #19331 71884d7 Thanks @ysitbon! - Activate the RTK Query supported-fiats flow and retire the legacy CVS polling path: boot-time query populates the Redux slice; settings and countervalue selectors read from the slice synchronously.
  • #18924 b2f4ae6 Thanks @philipptpunkt! - Fix the endless loading state when navigating back from the Swap success screen. React Navigation v7 pushed a new SwapPendingOperation on top of SwapLoading instead of reusing the existing one, leaving SwapLoading beneath the success screen. Any back gesture - Android system back, iOS swipe-back, or the close (X) button - would pop to SwapLoading and get stuck. The fix replaces the SwapSubScreensNavigator via BaseNavigator so the success screen always starts with a clean [SwapPendingOperation] stack, making all back paths (back button, close button, and via Swap history) return correctly to the Swap input.
  • #19536 f854c29 Thanks @amaslakov! - Warn and explain when Tezos staking is blocked by an unfinalizable unstake to another validator: translate the raw fee-estimation error into a clear message, and show an inline warning on the change-validator summary while a pending unstake is still unfinalizable
  • #18901 78efe69 Thanks @amaslakov! - Add test ids to the Tezos staking-section rows (staked and unstaking) so e2e can target them distinctly from the delegation card
  • #19589 9479c28 Thanks @sarneijim! - Keep large-screen upsell eligibility read-only and align the fallback CTA link
  • #19199 446e2b8 Thanks @tonykhaov! - Persist the large-screen upsell modal's frequency state (retries, lastSeenAt) across app restarts on mobile, via a new shared @ledgerhq/live-engagement Redux slice
