Summary

Implements the masternode (evonode) identity credit withdrawal that platform_wallet_manager_masternode_withdraw had stubbed out ("pending verified signer"), with both keys Platform accepts for it, plus the preflight a UI needs to offer it correctly:

  • Owner key (ProviderOwnerKeys, identity purpose OWNER): may withdraw, but Platform pays the registered payout address — an output script signed with it is rejected (signature_purpose_matches_requirements). The claim therefore carries no output script.
  • Transfer key (the pubkey behind the registered P2PKH payout script, identity purpose TRANSFER): may withdraw to any destination.

platform-wallet

  • PlatformWallet::masternode_withdrawal_keys (sync, seedless, no network): which of the two keys this wallet holds — owner via account-xpub derive-and-compare over the ProviderOwnerKeys pool depth (same approach as the operator ownership check), transfer via the funding accounts' address-pool lookup (same lookup as sign_message) — plus the payout address.
  • PlatformWallet::masternode_withdraw (async): fetch the owner identity (id = display-order proTxHash), select the matching OWNER / TRANSFER identity key (refuses to broadcast if the identity doesn't carry it), sign through a key-wallet Signer at the resolved derivation path via a DerivedKeyIdentitySigner adapter (binds the derived pubkey to the identity key hash before emitting the 65-byte recoverable signature, dashcore::signer::sign format), then withdraw_credits_with_signer.
  • select_transfer_withdrawal_key next to the existing select_owner_withdrawal_key; both are now used in production (dead-code allow removed).

platform-wallet-ffi

  • New platform_wallet_manager_masternode_withdrawal_keys preflight.
  • platform_wallet_manager_masternode_withdraw now takes a MnemonicResolverHandle + use_owner_key + optional dest_address and runs the claim through MnemonicResolverCoreSigner — the same resolver-backed signing as core_wallet_sign_message / core_wallet_tx_builder_finalize (seed never resident; handle-storage guard not held across the network/resolver round-trip). The masternode is resolved from the same aggregation platform_wallet_manager_list_masternodes renders.

Outcome typing / owner-index hint (review follow-ups)

  • Broadcast and result wait are split: a definitive rejection stays an ordinary retryable error; an ambiguous outcome is the new PlatformWalletError::MasternodeWithdrawalUnconfirmed → FFI code 42 ErrorMasternodeWithdrawalUnconfirmed → Swift .masternodeWithdrawalUnconfirmed / Kotlin MasternodeWithdrawalUnconfirmed (do NOT retry until the claimable balance is re-read — the nonce was consumed). The broadcast-outcome classifiers move out of the shielded-gated module into broadcast_outcome.
  • masternode_withdrawal_keys and both FFIs take an optional owner-key index hint (persisted ownerKeyIndex / host address join), verified by derivation before the pool-depth scan.

swift-sdk

  • PlatformWalletManager.masternodeWithdrawalKeys(walletId:proTxHash:)MasternodeWithdrawalKeys (ownerKeyIndex, transferKeyInWallet, payoutAddress, canChooseDestination, preferredSigningKey).
  • masternodeWithdraw(walletId:proTxHash:amountCredits:signingKey:destinationAddress:) is now async (detached — the FFI blocks on the Platform round-trip) and returns the remaining balance.
  • SwiftExampleApp: the Claim button is no longer gated off and calls the new API.

Consumer: dashpay/dashwallet-ios#1035 (evonode "Withdraw" screen).

Test plan

  • cargo test -p platform-wallet --lib -- masternode_withdrawal withdrawal::masternode_withdrawal_tests (8 tests: key selectors incl. decoys, signer adapter signature verifies via verify_hash_signature, refuses foreign keys / mismatched derived key, DIP-3 owner path, flags)
  • cargo test -p platform-wallet-ffi --lib -- masternode_withdrawal (owner-key + destination rejected before touching handles; invalid handle paths)
  • cargo clippy -p platform-wallet -p platform-wallet-ffi --all-targets -- -D warnings, cargo fmt
  • ./build_ios.sh --target sim (xcframework + SwiftExampleApp, warnings-as-errors)
  • Testnet claim from the iOS wallet (see app PR)

Summary by CodeRabbit

  • New Features

    • Added masternode reward withdrawals supporting owner and transfer keys.
    • Added preflight checks showing available signing keys, payout addresses, and destination options.
    • Added support for custom withdrawal destinations when using a transfer key.
    • Updated the example app with an enabled claim flow and clearer signing-key information.
  • Bug Fixes

    • Added explicit handling for withdrawals whose final outcome cannot be confirmed. These withdrawals are not safe to retry.
    • Improved broadcast outcome classification for failed and ambiguous transactions.

…out key
Implements the masternode (evonode) identity credit withdrawal that
`platform_wallet_manager_masternode_withdraw` had stubbed out, and adds
the preflight the UI needs to offer it correctly.
platform-wallet:
- `PlatformWallet::masternode_withdrawal_keys` (sync, seedless): which of
the two keys that may sign a masternode withdrawal this wallet holds —
the ProviderOwnerKeys owner key (account-xpub derive-and-compare over
the pool depth, like the operator check) and the payout-script key
(funding-account address-pool lookup) — plus the registered payout
address.
- `PlatformWallet::masternode_withdraw` (async): fetch the owner identity
(id = display-order proTxHash), select the matching OWNER or TRANSFER
identity key (refusing to broadcast when the identity doesn't carry
it), and sign through a key-wallet `Signer` at the resolved path via a
`DerivedKeyIdentitySigner` adapter that binds the derived pubkey to the
identity key hash before emitting the 65-byte recoverable signature.
Owner-key withdrawals carry no output script (Platform pays the payout
address; `signature_purpose_matches_requirements` rejects anything
else); transfer-key withdrawals take any destination.
- `select_transfer_withdrawal_key` next to the existing owner selector;
both now re-exported crate-wide and used in production.
platform-wallet-ffi:
- `platform_wallet_manager_masternode_withdrawal_keys` (new preflight).
- `platform_wallet_manager_masternode_withdraw` now takes a
`MnemonicResolverHandle` + `use_owner_key` + optional destination and
runs the claim through `MnemonicResolverCoreSigner`, the same
resolver-backed signing every other wallet-key path uses. The
masternode is resolved from the same aggregation the list renders.
swift-sdk:
- `masternodeWithdrawalKeys(walletId:proTxHash:)` and an async
`masternodeWithdraw(walletId:proTxHash:amountCredits:signingKey:destinationAddress:)`
wrapper (detached — the FFI blocks on the network round-trip).
- Example app: Claim is no longer gated off; it calls the new API.

Adds masternode credit withdrawal support with owner and transfer keys. The change includes wallet signing, broadcast outcome classification, FFI bindings, Kotlin and Swift error mappings, Swift manager APIs, and example-app claim UI updates.

Changes

Masternode withdrawal

Layer / File(s)Summary
Withdrawal key contracts and resolution
packages/rs-platform-wallet/src/wallet/masternode_withdrawal.rs, packages/rs-platform-wallet/src/wallet/identity/network/*, packages/rs-platform-wallet/src/wallet/core/*, packages/rs-platform-wallet/src/manager/accessors.rs
Adds withdrawal request and key types. Resolves owner and transfer keys. Exposes wallet helpers and validates key matches.

Builds and signs identity credit withdrawal transitions. Classifies definitive and ambiguous broadcast results. Reports unconfirmed execution without recommending resubmission.
FFI withdrawal bridge and result codes
packages/rs-platform-wallet-ffi/src/masternode_withdrawal.rs, packages/rs-platform-wallet-ffi/src/error.rs, packages/rs-platform-wallet-ffi/src/lib.rs
Adds key preflight and withdrawal FFI functions. Validates handles, pointers, destinations, networks, and key availability. Maps ambiguous withdrawals to result code 42.
SDK and claim UI integration
packages/kotlin-sdk/.../DashSdkError.kt, packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/*, packages/swift-sdk/SwiftExampleApp/.../MasternodeDetailView.swift
Maps the unconfirmed error in Kotlin and Swift. Adds Swift preflight and withdrawal APIs. Updates the claim view for transfer or owner signing, destination input, and balance reconciliation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟡 Moderate · up to fbdcf

The PR adds masternode credit withdrawal and UI support, but the current implementation can freeze the app while resolving keys, allow a retry using a stale balance after an ambiguous withdrawal, and accept a foreign-network destination through the Rust API. Merge should wait for these issues to be fixed or explicitly accepted by the owners.

Requesting changes for one post-broadcast safety issue and two functional regressions. The focused platform-wallet and platform-wallet-ffi tests pass locally; the macOS wallet CI job was canceled by its 30-minute timeout rather than a test assertion.

Comment threadpackages/rs-platform-wallet/src/wallet/masternode_withdrawal.rs Outdated
…x hint for masternode withdrawals
Review follow-ups on the masternode credit withdrawal:
- Split broadcast from the result wait so an ambiguous post-broadcast
outcome is preserved as `PlatformWalletError::MasternodeWithdrawalUnconfirmed`
(FFI code 42 `ErrorMasternodeWithdrawalUnconfirmed`, Swift
`.masternodeWithdrawalUnconfirmed`, Kotlin `MasternodeWithdrawalUnconfirmed`)
instead of an ordinary retryable error: the identity nonce was consumed,
so a blind retry could execute a second withdrawal. Definitive outcomes
(consensus rejection, transport verdict) keep their ordinary codes. The
broadcast-outcome classifiers move out of the `shielded`-gated module
into `broadcast_outcome` so both paths share one source of truth.
- `masternode_withdrawal_keys` / the two FFIs / Swift wrappers take an
optional owner-key index hint (the persisted ownership row or the host's
address join). Rust VERIFIES it by derivation before the pool-depth scan,
so restored wallets whose in-memory pool has no watermark still resolve
an owner key above the default 20-index window.
- SwiftExampleApp: Claim is gated on the SDK preflight (`canWithdraw`),
signs with its preferred key, lets a transfer-key wallet pick the
destination, passes the persisted owner index as the hint, and holds
Confirm disabled after an unconfirmed outcome until the balance is
refreshed.

…index hint for evonode withdrawals
Follows dashpay/platform#4451 review:
- An ambiguous claim outcome (`PlatformWalletError.masternodeWithdrawalUnconfirmed`
— broadcast accepted, result unconfirmed, identity nonce consumed) is a
terminal `.submittedUnconfirmed` phase: the sheet explains it may have
gone through, offers only Close (no Try again), and the detail screen
re-reads the claimable balance as the reconciliation step.
- The owner-key index from the masternode list's address join is passed to
the SDK preflight and the claim as a hint that Rust verifies by
derivation, so restored wallets whose in-memory pool has no watermark
still resolve an owner key above the default scan window.

Add unit tests for the shared classifiers.

carries_consensus_rejection and broadcast_definitely_failed now gate the retry decision for two money-moving paths: shielded spends and masternode withdrawals. The module carries no tests. A table test over the gRPC codes, AlreadyExists, NoAvailableAddresses, and the NoAvailableAddressesToRetry recursion would pin the contract at the point of definition instead of at each caller.

283-370: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a test that pins the code-42 mapping.

The tests cover early rejection and invalid handles. They do not cover the mapping that matters most for safety: PlatformWalletError::MasternodeWithdrawalUnconfirmedPlatformWalletFFIResultCode::ErrorMasternodeWithdrawalUnconfirmed. That numeric value is mirrored by hand in Swift (PlatformWalletResultCode.errorMasternodeWithdrawalUnconfirmed = 42) and Kotlin (42 -> PlatformWallet.MasternodeWithdrawalUnconfirmed), and there is no compile-time check across the ABI. A regression there turns a do-not-retry outcome into a generic error and permits a blind second withdrawal.

Add a network check at the wallet API boundary.

The FFI validates dest_address, but the public Rust API does not validate an explicit destination. A caller can pass a foreign-network address marked NetworkChecked with assume_checked(). Apply require_network(self.network()) before using the destination script.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win

Move the withdrawal-key preflight off the main actor.

loadWithdrawalKeys() is synchronous and .task (line 264) runs it on the main actor. masternodeWithdrawalKeys is a blocking FFI call: it takes the wallet-manager read lock and then runs a seedless derive-and-compare loop. When the persisted ownerKeyIndexHint is absent or stale, Rust falls back to scanning 0..owner_scan_max, deriving a key at each index. That blocks the UI while the view appears.

Every other FFI call in this view already hops off the main actor (fetchClaimableBalance uses Task.detached at line 470). Apply the same pattern here.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

prepareClaim() clears the unconfirmed latch without a balance refresh.

Line 308 resets claimOutcomeUnconfirmed = false. After an ambiguous outcome the sheet stays open with Confirm disabled, but the user can Cancel and tap Claim again. prepareClaim() then clears the latch and re-enables Confirm against a stale claimableCredits. That is the blind retry the code comments say the latch prevents.

Refresh the balance instead of clearing the flag, so only fetchClaimableBalance() owns the reset.

🛡️ Proposed fix
 private func prepareClaim() {
claimError = nil
- claimOutcomeUnconfirmed = false
claimAmountText = Self.creditsAsDash(defaultClaimCredits)
.replacingOccurrences(of: " DASH", with: "")
claimDestinationText = withdrawalKeys?.payoutAddress ?? ""
showClaimSheet = true
}

fetchClaimableBalance() already clears the latch at line 459, so a Refresh remains the single reconciliation path.

* feat(masternodes): withdraw an evonode's claimable balance
Adds a Withdraw flow to the evonode detail screen for the identity credits
that accrue on a masternode's owner identity (the "claimable balance" the
screen already showed read-only).
Two wallet keys can sign the claim, and Dash Platform treats them
differently, so the UI is driven by an SDK preflight
(`PlatformWalletManager.masternodeWithdrawalKeys`):
- payout (transfer) key in this wallet → the destination is editable
(defaults to the registered payout address; paste / QR scan / reset);
- only the owner key in this wallet → the destination is locked to the
registered payout address, with the reason explained inline;
- neither → no Withdraw button, one-line explanation instead.
`EvonodeWithdrawalScreen` (SwiftUI + `EvonodeWithdrawalViewModel`): DASH /
fiat keypad with Max (keeps a 0.005 DASH reserve — Platform's minimum
credit-withdrawal fee is 0.004 DASH), Platform minimum-withdrawal and
ceiling validation, a "How it works" card (credits → DASH on the Core
chain, fee taken from the evonode balance), and a confirmation sheet that
runs the auth gate and then `masternodeWithdraw` (all orchestration —
identity fetch, key selection, resolver-backed signing, broadcast — is in
the SDK). Success reports the remaining claimable balance back to the
detail screen.
Requires dashpay/platform `feat/masternode-withdraw` (the FFI was a stub
before it).

* fix(masternodes): non-retryable unconfirmed outcome + verified owner-index hint for evonode withdrawals
Follows dashpay/platform#4451 review:
- An ambiguous claim outcome (`PlatformWalletError.masternodeWithdrawalUnconfirmed`
— broadcast accepted, result unconfirmed, identity nonce consumed) is a
terminal `.submittedUnconfirmed` phase: the sheet explains it may have
gone through, offers only Close (no Try again), and the detail screen
re-reads the claimable balance as the reconciliation step.
- The owner-key index from the masternode list's address join is passed to
the SDK preflight and the claim as a hint that Rust verifies by
derivation, so restored wallets whose in-memory pool has no watermark
still resolve an owner key above the default scan window.

* refactor(wallet): detail view model, unit-preserving amount switch, block claims during reconciliation
CodeRabbit follow-ups on the evonode withdrawal:
- SDK-backed loading (claimable balance, withdrawal-key preflight) moves out
of `MasternodeDetailScreen` into `MasternodeDetailViewModel`; the view
only renders and forwards actions.
- Switching the typing unit (DASH/fiat) now converts the displayed amount
via `EvonodeWithdrawalViewModel.setUnit`, so the amount the user meant is
preserved; a pinned Max stays pinned to the exact credit figure.
- After an unconfirmed claim outcome the stale balance is cleared
synchronously (hiding Withdraw) before the reconciling re-read, so a
second claim can't be started on a figure that may no longer exist.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(wallet): no "credits" in evonode withdrawal copy — everything is DASH
User-facing strings never mention Platform credits: the detail screen shows
the claimable balance as a single DASH row, and the withdrawal screen /
confirmation talk about the balance and the payout in DASH only.

Brings the branch up to date with upstream after #4451 (masternode
credit withdrawals), #4452, #4453, #4456, and #4461 landed on v4.2-dev.
One conflict, in packages/rs-platform-wallet/src/wallet/core/mod.rs:
a module-registration collision where this branch adds
'pub mod spend_observer;' and upstream adds
'pub(crate) use sign_message::is_signable_funding_account;' at the same
spot. Resolved as the union — both lines kept, no semantic overlap.
Auto-merged overlaps verified by hand: both error.rs files and
DashSdkError.kt gained disjoint additions (upstream's
MasternodeWithdrawalUnconfirmed / FFI code 42 alongside this branch's
StaleReservation reusing code 34 — codes distinct, both mapping arms
present). generation.rs (the broadcast-fence redesign) was touched by
this branch only.
Verified: cargo check -p platform-wallet -p platform-wallet-ffi clean;
cargo test -p platform-wallet wallet::core::generation — 15/15 passed,
including the settle-boundary and handoff tests.

Brings the shielded-invite branch up to date with upstream v4.2-dev
(#4451 masternode credit withdrawals, #4452, #4453, #4456, #4461).
One conflict, in rs-platform-wallet/src/wallet/shielded/operations.rs:
upstream #4451 moved carries_consensus_rejection() and
broadcast_definitely_failed() out of operations.rs into the new shared
crate::broadcast_outcome module (so masternode withdrawals can reuse
them), while this branch had inserted its one-time-key claim machinery
(NullifierSpentStatus, claim-evidence resolution) directly after those
functions. Resolved by dropping the now-local duplicate of
broadcast_definitely_failed() — its body is byte-identical to the moved
copy, and the file already imports both helpers from
crate::broadcast_outcome via upstream's auto-merged use line — and
keeping this branch's one-time-key claim block in place. No semantic
changes to either side.
Verified: cargo check -p platform-wallet -p platform-wallet-ffi
-p rs-unified-sdk-jni clean; cargo test -p platform-wallet
--features shielded wallet::shielded = 205 passed, 0 failed
(includes the one_time_claim_evidence and note_selection suites).

…4356 must renumber
42: merged #4451 took the number active #4356 had claimed for
ErrorAssetLockInputConflict — merged ABI wins, the open PR renumbers via
the frontier. 46: #4465 initially minted 43 (held by #4313), was flagged
in review, and renumbered to the frontier before merging — Rust and Swift
together. Frontier moves to 47.

Reconciles the branch with the protocol-14 shielded fee rebalance
(#4467) and the broadcast-outcome extraction (#4451).
The one textual conflict was packages/rs-dpp/src/shielded/mod.rs: this
branch adds the wire-cost model (SHIELDED_ACTION_WIRE_BYTES,
SHIELDED_PROOF_WIRE_BYTES_PER_ACTION, envelope helpers) in the same
region where #4467 deletes SHIELDED_STORAGE_BYTES_PER_ACTION (replaced
by the versioned event constant `shielded_storage_bytes_per_action`
beside the compute fees). Resolution keeps both changes: the wire-cost
block stays, the storage constant goes. No other reference to the
deleted constant existed on this branch.
No fee numbers needed recalibrating: the output-aware predictor
(ShieldedFeeKind::compute / select_notes_with_fee) reads exclusively
through dpp's compute_* fee functions, which #4467 rewired to the
versioned constants, and every test on this branch derives its
expectations from compute_minimum_shielded_fee(n, version) rather than
hardcoding magnitudes - including the strict-change exact-fit boundary
test and the u64::MAX overflow boundary test, whose inputs are
expressed relative to fee_2/fee_3 and rescale automatically. The FFI
fee-estimate goldens carry upstream's v14 values (114,140,000 /
120,222,800 / 226,480,000 = 40M proof + n x 22M processing +
n x 550B x 27,400/B + flat extras), which merged cleanly.
Verified: cargo check -p platform-wallet -p platform-wallet-ffi
-p rs-unified-sdk-jni clean; 158 wallet::shielded platform-wallet
tests, 233 dpp shielded tests, 16 platform-wallet-ffi shielded_send
tests all pass.
