…vate keys Adds wallet-independent masternode tracking on top of the SwiftDashSDK locator/registry (platform feat/tracked-masternodes): Masternodes → + finds any node on the network from one field — IP, proTxHash (explorer hex), or a private key (owner/voting/payout WIF or hex, operator BLS hex, Tenderdash node key). A key match pre-fills that key's field so it is never typed twice; owner/payout keys are located via an opt-in "Search Platform too" toggle (the lookup reveals the key's public fingerprint to a DAPI node, so it is off by default). Tracking is in ADDITION to the wallet-derived masternode feature: tracked nodes render in their own "Tracked" list section with the same row/detail components, carry an optional label, and enrich themselves from the masternode list, the node's Platform identities and its ProRegTx (registration height, collateral, owner/voting/payout references). Keys the user attaches live in the app keychain only (TrackedMasternodeKeyVault; this-device-only, never synced), verified against the node before saving — a key that can't be verified yet is stored as "can't verify yet", never claimed valid. Actions light up by attached keys through the SDK's shared capability gating: withdraw the evonode's claimable balance with the owner or payout key (authenticate → read vault → one-shot SDK signing call, nothing retained), and contested- resource voting picks up tracked nodes whose voting key is attached (MasternodeVoterRegistry key source enum). Tracked evonodes join the Nodes-shortcut epoch-blocks tally. Reset-all removes tracked masternodes and their vaulted keys; deleting one wallet of several leaves them (they belong to no wallet).

…ative path The feature was built against a temporary absolute path to the platform feat/tracked-masternodes worktree; the committed project file must reference ../platform/packages/swift-sdk like every other checkout. Building this branch requires ../platform on dashpay/platform feat/tracked-masternodes (or its merge) with a rebuilt DashSDKFFI xcframework.

118-166: 🎯 Functional Correctness | 🔴 Critical | ⚡ Quick winTracked nodes are unreachable when the wallet has no masternodes.
votableNodes()returns early in two places before line 164:
- Line 119-122 requires a loaded wallet and
walletId.- Line 126 returns
.emptywheneligibleis empty.Tracked masternodes are wallet-independent. A user who tracks a node and attaches its voting key, but owns no wallet-registered masternode, hits the line 126 early return.
trackedVotableNodesnever runs, so the node is not votable. That is the common case for this feature and it removes the contested-resource voting capability the PR adds.Resolve tracked nodes first, then merge, so neither early return can drop them.

cleanup completes before SwiftDashSDKHost.shared.stop() tears down its
dependencies. Remove the trailing unawaited Task and preserve the existing wipe
flow.

Masternodes/AddMasternodeViewModel.swift:
- Around line 203-238: Update revalidateKeys() to populate non-empty key fields
with .unverifiable when SwiftDashSDKHost.shared.manager is unavailable, rather
than returning with an empty keyStates dictionary. Preserve empty fields as
.empty so canSaveKeys continues allowing track-only saves while displaying the
unverifiable caveat for entered keys.

Masternodes/TrackedMasternodeDetailScreen.swift:
- Around line 392-395: Move the credits-to-DASH conversion and display
formatting out of MasternodeDetailScreen into TrackedMasternodeDetailViewModel.
Expose formatted credit strings using the existing
formattedDashAmountWithoutCurrencySymbol formatter and the view model’s
creditsAsDash value, then update both Balance rows to consume those view-model
properties without protocol constants, arithmetic, or String formatting in the
SwiftUI View.
- Around line 155-170: Update withdrawAmountCredits to validate the scaled
Decimal against Decimal(UInt64.max) before converting it with
NSDecimalNumber.uint64Value; return nil for values above the UInt64 limit, while
preserving the existing positive-amount validation and normal conversion path.
- Around line 116-122: Update setLabel to re-read and assign the tracked
masternode record after manager.setTrackedMasternodeLabel completes, so
viewModel.record.label immediately reflects the saved value and remains
consistent with the refreshed list.

Platform dependency merged — dashpay/platform#4465 landed on |
QuantumExplorer
changed the title
…t hygiene CodeRabbit round on #1049 — all five confirmed against the code: * MasternodeVoterRegistry resolves tracked votable nodes BEFORE the empty-eligible early return: a wallet with no masternodes of its own — the common case for tracking — could never vote with an attached voting key. Exclusion is by the wallet's eligible set so a wallet-registered node never doubles into the tracked list. * The reset-all tracked-state cleanup runs synchronously on the main actor BEFORE `handleWalletWiped()` tears down the host manager and model container the cleanup needs; the unawaited trailing task raced that teardown. * `revalidateKeys()` marks non-empty fields "can't verify yet" when the SDK manager isn't up, instead of leaving `keyStates` empty — which let `saveKeys()` store unverified keys with no badge and no caveat. * The DASH→credits conversion rejects amounts past `UInt64.max` before `NSDecimalNumber.uint64Value` (undefined past the range) can wrap an absurd input into a small value that passes the max-withdrawal check. * `setLabel` re-reads the record (local registry call) so the detail title updates with the list; credits→DASH formatting moved off the Views onto the view model, deriving 1 DASH = 1e11 credits from `EvonodeWithdrawalViewModel.creditsPerDuff` per the repo guardrails.

Adds wallet-independent masternode tracking, in ADDITION to the existing wallet-derived feature. Masternodes → + finds any node on the network from one field — an IP (
1.2.3.4,1.2.3.4:9999, a DAPI URL), a proTxHash (explorer hex), or any of its private keys (owner / voting / payout WIF or hex, operator BLS hex, Tenderdash node key in dashmate's base64 or hex). When a key finds the node, it is pre-filled into that key's field so it never has to be entered twice.Depends on dashpay/platform#4465 — MERGED to
v4.2-devas3cf5e665fc, so this PR is unblocked: all non-UI logic (input parsing, list lookups, key→role matching, verification, the tracked registry + enrichment, withdraw-with-key signing, capability gating) lives inplatform-walletbehind the FFI so Android reuses it unchanged. Build../platformatv4.2-devhead (≥3cf5e665fc) and rebuild the xcframework.What's in the flow
TrackedMasternodeKeyVault, this-device-only, not synced); the SDK receives a key per signing call and retains nothing.Screenshots
Verification
Clean
dashpayscheme build (arm64 sim) against platformfeat/tracked-masternodes. Mainnet smoke on a live wallet sim: located31.220.91.60by IP and a second node, tracked both, enrichment filled registration + payout data, claimable balance fetched (0.00295865 DASH), Request status answered live (DAPI 4.1.1 / Drive 4.1.1 / Tenderdash 1.7.0), and both nodes survived an app reinstall (SwiftData persistence round-trip). Key fields use a plain monospaced text field on purpose — a SecureField triggers iOS's strong-password AutoFill sheet over masternode keys.🤖 Generated with Claude Code
