+# Swap Feature
+
+Token-to-token exchange feature. Users select FROM and TO tokens, get quotes from providers (DEX/CEX), approve ERC-20 allowances if needed, and execute swaps.
+
+## Module Structure
+
+```
+features/swap/
+  api/          — Public contracts (SwapComponent, SwapEntryComponent, SwapFeatureToggles)
+  impl/         — UI, model, navigation, DI, token selection subfeature
+  domain/       — Business logic (SwapInteractor) + domain models
+    api/        — Domain interfaces
+    models/     — Domain model types (SwapPair, SwapProvider, SwapState, etc.)
+  data/         — Repository implementations, Retrofit APIs, Moshi DTOs
+```
+
+**Package naming:** API = `com.tangem.features.swap`, Impl = `com.tangem.feature.swap` (singular `feature`, legacy inconsistency).
+
+## Key Components
+
+### SwapComponent (API)
+Entry point. `Params` requires `currencyFrom`, `userWalletId`, `screenSource`. Optional: `currencyTo`, `isInitialReverseOrder`, `tangemPayInput`, `preselectedToToken`, `preselectedAccount`.
+
+### SwapEntryComponent (API)
+Gateway component with sealed `Params`: `Story`, `Empty`, `Selected`, `Payment`. Routes to stories or directly to swap based on input type. See `entry/SwapEntryRoute.kt` for route definitions.
+
+### DefaultSwapComponent (impl)
+Decompose component. Creates `SwapModel` via `getOrCreateModel(params)`.
+
+**Child navigation:**
+- `childStack(SwapRoute)` for screen navigation — `SwapRoute.Main`, `SwapRoute.Success`, `SwapRoute.SelectToken(isFromDirection)` rendered via `Children` composable with fade animation
+- `SlotNavigation<Unit>` for approval bottom sheet (`GiveApprovalComponent`)
+- `SlotNavigation<FeeSelectorConfig>` for fee selector block
+
+**Injected factories:** `SwapFeeSelectorBlockComponent.Factory`, `GiveApprovalComponent.Factory`, `ChooseTokenComponent.Factory`.
+
+### SwapModel (impl)
+`@ModelScoped`, extends `Model()`. The central coordinator — ~1500 lines.
+
+**Key state:**
+- `dataStateStateFlow: MutableStateFlow<SwapProcessDataState>` — reactive domain data (from/to tokens, pairs, providers, amounts, fees)
+- `uiState: SwapStateHolder by mutableStateOf()` — Compose UI state built by `StateBuilder`
+- `feeSelectorRepository: FeeSelectorRepository` — fee state management
+- `stackNavigation: StackNavigation<SwapRoute>` — stack navigation exposed from `SwapRouter`
+- `approvalSlotNavigation: SlotNavigation<Unit>` — approval bottom sheet
+
+**Navigation:**
+- `SwapRouter` wraps `AppRouter` + `StackNavigation<SwapRoute>` for screen switching and back navigation
+- `swapRouter.openScreen(SwapRoute.SelectToken(isFromDirection))` to push token selection
+- `swapRouter.openScreen(SwapRoute.Success)` replaces current with success screen
+- `swapRouter.back()` — pops local stack or exits swap via AppRouter
+
+**Initialization flow (init block):**
+1. Subscribes to `chooseTokenBridge.onCurrencyChosen` → `onTokenSelect(result)`
+2. Subscribes to `chooseTokenBridge.onClose` → pops slot navigation
+3. Checks `ShouldShowStoriesUseCase` → pushes `AppRoute.Stories` if first-time swap
+4. Resolves user country for FCA restrictions
+5. Loads primary account status, initial currencies, and starts swap pair loading
+
+**Token selection flow:**
+1. User taps FROM or TO card → `onSelectTokenClick(direction)` pushes `SwapRoute.SelectToken(isFromDirection)` to stack
+2. Stack creates `ChooseTokenComponent` with appropriate bridge (FROM or TO)
+3. `ChooseTokenBridge` communicates selection result via Channel
+4. `onTokenSelect(result)` assigns selected token to FROM or TO based on `isFromDirection`
+
+**Swap execution flow:**
+1. `onSwapClick()` — validates state, checks approval, initiates transaction
+2. If approval needed → `approvalSlotNavigation.activate(Unit)`
+3. On approval done → reloads quotes
+4. On swap success → `swapRouter.openScreen(SwapRoute.Success)`
+
+### StateBuilder (impl)
+Pure transformation class. Takes `UiActions` + providers, builds `SwapStateHolder` from `SwapProcessDataState`.
+
+Key methods: `createInitialLoadingState`, `createQuotesLoadedState`, `createSuccessState`, `loadingPermissionState`, `updateSwapAmount`, `addNotification`, `dismissBottomSheet`.
+
+### SwapRouter (impl)
+Wraps `AppRouter` + `StackNavigation<SwapRoute>`. Handles `openScreen(SwapRoute)` to push/replace stack entries and `back()` with special logic: SelectToken pops local stack, Success exits to screen before SwapCrypto in app stack, Main pops AppRouter. `openTokenDetails()` navigates to `AppRoute.CurrencyDetails`.
+
+## Token Selection Subfeature (impl)
+
+Self-contained within `choosetoken/` package:
+- `ChooseTokenComponent` — API with `Params(bridge, settings, analyticsPayload)`
+- `ChooseTokenBridge` — Channel-based communication: `onCurrencyChosen`, `onClose`, `onTokenSelected` (legacy), `onNewTokenAdded` (legacy). Has `settingsStateFlow` for dynamic settings.
+- `ChooseTokenComponent.Settings` — `SwapFrom` (no market block) vs `SwapTo` (with market block)
+- `ChooseTokenResult` — Contains `CryptoCurrencyStatus`, `AccountStatus`, `UserWallet`
+- `DefaultChooseTokenComponent` — Has its own `ChooseTokenModel` and optional `AddToPortfolioComponent` bottom sheet slot
+
+## Domain Layer
+
+### SwapInteractor
+Central domain interface. Methods:
+- `getPair(from, to, filterProviderTypes)` → `Either<ExpressError, List<SwapPairLeast>>`
+- `findBestQuote(from, to, providers, amount, ...)` → `Map<SwapProvider, SwapState>`
+- `onSwap(from, to, provider, swapData, amount, fee, ...)` → `SwapTransactionState`
+- `loadFeeForSwapTransaction(...)` → `Either<GetFeeError, TransactionFee/TransactionFeeExtended>`
+- `getInitialCurrencyToSwap(accountStatusList, fromUserWallet, isReverse)` → `AccountCryptoCurrencyStatus?`
+- `getTokenBalance(token)` → `SwapAmount`
+
+### Key Domain Models
+- `SwapPairLeast` — from/to token info + providers list
+- `SwapProvider` — providerId, name, type (DEX/CEX/DEX_BRIDGE), rates, slippage, TOS links
+- `SwapState` — sealed: `QuotesLoadedState`, `SwapError`, `EmptyAmountState`
+- `SwapCurrencyStatus` — wraps `CryptoCurrencyStatus` + `UserWallet` + `Account`
+- `SwapAmount` — value + decimals pair
+- `SwapDataModel` — quote result with transaction data
+
+## DI Modules
+
+| Module | Scope | Bindings |
+|--------|-------|----------|
+| `SwapFeatureModule` | Singleton | `SwapComponent.Factory`, `SwapFeatureToggles` |
+| `SwapModelModule` | ModelComponent | `SwapModel` into model map |
+| `SwapEntryModule` | Singleton + Model | `SwapEntryComponent.Factory`, `SwapEntryModel` |
+| `ChooseTokenModule` | Singleton + Model | `ChooseTokenComponent.Factory`, `ChooseTokenBridge.Factory`, `ChooseTokenModel` |
+| `SwapSingletonModule` | Singleton | `AmountFormatter` |
+
+## UI Layer
+
+- `SwapScreen` — main swap composable (send card, receive card, swap button, provider, notifications, fee)
+- `SwapSuccessScreen` — post-swap success with transaction details
+- `SwapScreenContent` — layout with `ConstraintLayout` for card positioning
+- `TransactionCard` / `TransactionCardEmpty` — token cards with amount input
+- Token cards pass `TokenSelectionDirection.FROM` / `.TO` to `onSelectTokenClick`
+
+## Navigation Summary
+
+```
+AppRouter (global)
+  └─ AppRoute.Swap → DefaultSwapComponent
+       ├─ childStack(SwapRoute)
+       │    ├─ SwapRoute.Main → SwapMainChild (renders SwapScreen)
+       │    ├─ SwapRoute.Success → SwapSuccessChild (renders SwapSuccessScreen)
