 ### Added
 
+- Add `RampsController:sendPix` orchestration for Money Account Pix offramp: register Pix destination, exact-out autoramp quote, create autoramp, persist via `addAutoramp`, then `TransactionPayController:submitMoneyAccountVaultWithdraw` (confirmation sheet is a side effect of withdraw; result resolves after approval). Requires a stable `clientRequestId` for NeoBank idempotency + sendPix in-flight dedupe. Pix key metadata stays out of the slim withdraw request. Depends on NeoBank Pix methods (#9851) and vault withdraw (#9849).
+- Populate `AutorampRemoteSnapshot.walletAddress` from the first usable Iron `deposit_rails` Crypto Hex when top-level wallet fields are absent (`extractIronCryptoDepositAddress`), so crypto→Pix create responses keep a deposit address for vault withdraw / `addAutoramp`.
 - Add NeoBankService Pix / autoramp quote client methods and messenger actions, targeting the neobank-proxy `/neobank` prefix on the Ramp API host: `registerPixAddress`, `getAutorampQuote`, `createAutoramp`, `getAutorampQuoteForAutoramp`, `attachAutorampQuote`, and `getCustomerByExternalId`. Pix/quote helpers return parsed proxy JSON; `createAutoramp` maps autoramp-shaped responses via `mapNeoBankAutorampToRemoteSnapshot` (same as `getAutoramp`). Optional `Idempotency-Key` is supported on mutating calls.
 - Export `TERMINAL_ORDER_STATUSES` and `isTerminalOrderStatus()` so consuming clients can share the controller's terminal order status set instead of maintaining duplicate copies. ([#9679](https://github.com/MetaMask/core/pull/9679))
