feat(platform-wallet): rotate a masternode's keys into the wallet - #5889
A masternode owner whose owner key is in the wallet, but whose operator or voting key is not, cannot move those keys into the wallet from the phone.
This PR carries #4519 forward onto the current v5.1-dev. It holds the 13 commits of #4519 by QuantumExplorer, cherry-picked unchanged apart from three import conflicts, plus one commit that ports them to the current base. #4519 was written against v4.2-dev and no longer merges.
An owner-signed ProUpRegTx rotates a masternode's operator key, voting key or both to wallet keys, for a wallet-owned masternode (owner key by index) and for a tracked one (owner key held by the host). Each has a broadcast form and a prepare-only form.
Rotating the operator key makes Core reset the masternode's service fields and PoSe-ban it. A second call sends a ProUpServTx that re-asserts service values the caller captured before the rotation, signed with the wallet's new operator key.
provider_key_candidates lists the wallet's operator or voting keys by index, joined against the masternode list, so a key picker can show which keys are unused network-wide.
FFI externs and Swift wrappers for all of the above.
The port commit (fix(platform-wallet): port the key rotation to v5.1-dev):
An entry whose version-3 address map still lists addresses is refused on that path: the values name one address and would replace the whole map.
The owner signature and the operator key re-encoding use the current secp256k1 0.33 and rust-dashcore BLS APIs.
Tests are updated for the current list entry and payload types. A Dash address is now always P2PKH or P2SH, so the witness payout test checks the script rule directly.
Limits that remain:
Rotating the operator key of a masternode that already has a version-3 address map is refused. The reactivation takes one address per service and cannot restore a map with several.
Whether V24 is active is read from the masternode list and, when the list cannot tell, from the coinbase of the newest masternode list diff the SPV client validated. This applies to the existing unban path too and covers the limitation tracked in fix(platform-wallet): detect Core V24 from the SPV coinbase on v5.1 when building an evonode ProUpServTx #5568. Until the SPV client has synced a diff past activation, an evonode update is still built at version 2 and Core refuses it; a retry builds version 3.
The caller must capture the service values before rotating and keep them until the reactivation. Neither the wallet nor the SDK stores them.
The four new FFI externs resolve the owner and operator keys through the helper the unban path already uses in masternode_update_service.rs. Moving that key-source choice into platform-wallet is tracked for all callers in refactor(platform-wallet): own the key-source choice natively #5740.
How Has This Been Tested?
cargo test -p platform-wallet -p platform-wallet-ffi --all-features: 2052 and 573 tests pass, none fail.
cargo clippy -p platform-wallet -p platform-wallet-ffi --all-targets --all-features -- -D warnings and cargo fmt --all -- --check are clean.
packages/swift-sdk/build_ios.sh --target sim succeeds, including the SwiftExampleApp build.
New tests cover the reactivation from values at version 2 and version 3, for evonodes and regular masternodes, and its refusals.
Not tested: the full rotate, ban, reactivate cycle against a real network. It needs a testnet run before any mainnet use. cargo check --workspace and the Kotlin JNI crate were not built locally.
Breaking Changes
No consensus or FFI break; the FFI and Swift additions are additive.
One Rust source break in platform-wallet: the public MasternodeListSummary gains the fields service_addresses and operator_key_is_legacy, so code that builds it with a struct literal or destructures it exhaustively no longer compiles. Build it with MasternodeListSummary::from_entry where a raw list entry is at hand; otherwise set service_addresses to every endpoint the entry advertises and operator_key_is_legacy to whether the entry is version 1.

Summary by CodeRabbit
New Features
Added masternode operator and voting key rotation, with options to prepare transactions or broadcast them.
Added service updates with caller-specified endpoint and platform details, also available as prepare-only transactions.
Added provider key candidate lookup, including key usage and associated masternode information.
Masternode summaries now include all service endpoints and indicate whether the operator key uses legacy serialization.
Added support for looking up tracked provider-key ranges and safely handling wallets that are no longer available.
…'s keys into the wallet
execute/prepare_masternode_update_registrar builds, owner-signs, funds,
input-signs and (execute) broadcasts the provider update registrar
transaction that rotates a masternode's operator and/or voting key to
fresh wallet keys — Core's protx update_registrar — riding the same
payload-finalizer seam as the update-service path.
The owner's payload signature is the 65-byte compact recoverable ECDSA
over base_payload_hash (Core's CHashSigner form, hash signed directly),
pinned by the real testnet vector embedded in dashcore's payload tests:
the vector's base_payload_hash is asserted byte-exact and the signing
helper's output is recovered back to the owner key id.
Preflights, before any signing or network work: the owner secret must
hash to the ProRegTx's immutable keyIDOwner (fetched txid-bound); a
chosen operator key must be unused across the whole masternode list
under both serializations (consensus uniqueness); the payout address is
always required and network-checked — the payload replaces the payout
script on-chain; and rotating the operator key of a v3 extended-net-info
entry is refused, since the mandatory reactivation would replace its
endpoint map.
Because a ProUpRegTx that changes the operator key resets the entry's
service fields and PoSe-bans it until the new operator reactivates it,
this commit also adds the reactivation half: the explicit-values
update-service variant (prepare/execute_masternode_update_service_with_
values) re-asserts caller-captured service and platform values instead
of copying the reset entry, and provider_key_candidates lists the
wallet's operator/voting keys joined against the list so pickers can
default to (and enforce) network-wide-unused keys.
Shared registration-payload fetching is refactored out of the unban's
reward rule rather than duplicated.

…Swift wrappers
Additive entry points mirroring the update-service families:
- platform_wallet_manager_masternode_update_registrar and the tracked
form (host-vaulted owner key text), each with a _prepare_ sibling that
registers the signed transaction in the existing core
signed-transaction storage for the review-before-broadcast step.
- platform_wallet_manager_masternode_update_service_with_values (+
prepare): stage two of an operator rotation — no tracked form, since
the post-rotation operator key is by definition a wallet key.
- platform_wallet_manager_provider_key_candidates (+ free): the wallet's
operator/voting keys by index with network-wide usage, keyed by the
same account-type tags every provider-key FFI uses.
The unban module's derive helper generalizes to any provider kind
(owner keys included) instead of being copied, and its context resolver
and secret parsers are shared. Out-params are zeroed before any other
pointer check, per the crate contract, with tests.
Swift: masternodeUpdateRegistrar / trackedMasternodeUpdateRegistrar (+
prepare), masternodeUpdateServiceWithValues (+ prepare), and
providerKeyCandidates returning typed candidate rows.

…ral's embedded indentation, repoint a renamed doc link
- provider_key_candidates now refuses counts above a shared
MAX_PROVIDER_KEY_CANDIDATES (256) before any allocation — an arbitrary
external count fed Vec::with_capacity and could abort the process. The
FFI re-exports the bound (asserted equal in tests) and the Swift
wrapper guards against it up front.
- The values-path extended-net-info error message had the source
indentation baked into the literal (missing line continuations).
- The registration-fetch doc pointed at a function renamed in this
branch.

…legacy-key handling, values-path semantics, NUL guards, candidate tests
- Payout scripts are now gated to P2PKH/P2SH in both payout resolvers
(consensus rejects every other type as bad-protx-payee), and the
registrar refuses a P2PKH payout paid to the owner key or the
payload's final voting key (bad-protx-payee-reuse) — both hashes are
known before funding, so the doomed transaction never gets signed.
- A kept operator key is normalized by the ENTRY VERSION, not the bytes:
MasternodeListSummary gains operator_key_is_legacy (entry.version < 2,
persisted leniently), and a legacy key re-entering a version-2 payload
is parsed under Legacy and reserialized to basic. Byte-sniffing was
proven unsound in tests — legacy bytes also parse under the basic
scheme as a different flag reading.
- The explicit-values service path takes pro_tx_hash and the payout
address directly instead of MasternodeUpdateServiceParams, whose
documented platform_p2p_port semantics contradicted the values API.
- Swift wrappers guard every string parameter against embedded NUL
before C-string marshalling, matching the existing wrappers — a
truncated payout/key/service must never differ from what the caller
supplied.
- provider_key_candidates gains behavioral tests: modern- and
legacy-serialization operator joins, voting key-id joins, unused
retention, kind refusals, the zero count and the bound.

The fully-qualified ProviderRegistrationPayload return type pushed both
shared-helper signatures past rustfmt's max width, so the formatter was
skipping the lines entirely and the missing space before the brace
survived every fmt pass. Import the type instead so the signatures are
short enough for rustfmt to own.
…service values before funding
Review follow-ups on the ProUpRegTx / ProUpServTx orchestrators:
- Resolve the masternode's collateral script from the txid-bound ProRegTx
(internal collateral) or a txid-bound fetch of the external collateral
transaction, and refuse a final voting key or owner key at the
collateral's P2PKH destination (Core's bad-protx-collateral-reuse);
for a v3 entry also refuse a payout equal to the collateral script
(bad-protx-payee-reuse). Candidate discovery joins against DML voting
fields only, so a key that once funded the collateral looked unused.
- Validate explicit ProUpServTx values against MnNetInfo::ValidateService,
CheckProviderNetworkFields and the network-wide uniqueness pass: IPv4
only, non-zero routable port with the mainnet-port rule, non-null
platform node id, mainnet platform port defaults, no port collisions,
and no service endpoint or platform node id already advertised by any
other entry. MasternodeListSummary now carries every socket endpoint
of an extended entry's map so the uniqueness check sees secondary
addresses, with the snapshot format extended backward-compatibly.
- Keep the typed dash_sdk::Error when a transaction fetch fails; the
invalid-data shapes are reserved for responses that fail validation.
- Split the registrar orchestrator so the whole wiring below the network
fetches is exercised by a funded test that asserts the proTxHash,
operator key, voting hash, payout script, inputs hash and recovered
owner signature, plus the collateral preflight wired through it.

…, catch P2PK collateral reuse
Review round three on the registrar path:
- prepare_masternode_update_registrar ran the assembly (which derives
wallet keys via tokio blocking read-locks) directly in its async body,
and the candidates FFI ran provider_key_candidates inside
block_on_worker's spawned task — both a documented blocking_read panic
on an async worker, aborting across the C ABI. The orchestrator now
assembles on the blocking pool (spawn_blocking, with a regression test
driving the seam from a runtime worker), and the candidates extern
awaits only the list read, deriving on the plain FFI thread like the
per-index derive extern.
- The collateral-reuse preflight only extracted P2PKH destinations;
Core's ExtractDestination also converts a valid P2PK collateral to a
PKHash over the key's original serialization, so a P2PK collateral at
the voting or owner key slipped through to a deterministic consensus
rejection. Both forms are extracted now, tested compressed and
uncompressed.
- The owner-key and voting-key collateral collisions report separate
errors: re-choosing the voting key clears one, while the immutable
owner key's collision cannot be fixed with a ProUpRegTx at all.

…wn operator key
Core's CheckProUpRegTx duplicate-key checks both exclude the node being
updated (HasOperatorKeyUnderAnyScheme's self parameter, and the
proTxHash != otherDmn->proTxHash guard on the unique-property lookup),
so re-asserting the masternode's current operator key — a retry, or a
voting-only change re-selecting the same operator index — is consensus
valid. The wallet preflight refused it as a duplicate; it now skips the
target entry while still rejecting clashes with every other masternode.

… panicking in provider key derivation
resolve_context hands the FFI an Arc<PlatformWallet> whose underlying
key wallet the host can remove while the candidates extern awaits the
masternode list (Swift's providerKeyCandidates runs detached from the
deletion admission gate). derive_provider_key_at_index then hit the
read guard's expect("wallet exists in guard"), aborting at the
non-unwinding C boundary. The guard gains a fallible try_wallet(), and
the derivation resolves the wallet once through it, returning
WalletNotFound for the race — covering the registrar assembly path the
same way. Regression: removing the wallet after resolving the handle
makes provider_key_candidates return the error.

…t hygiene from review
Three review suggestions, each verified against Core's develop sources:
- Core's CNetAddr::IsValid runs before (and independent of) the
routability requirement, so the unspecified and broadcast IPv4
addresses are invalid on every network — the values validator now
rejects 0.0.0.0 and 255.255.255.255 even on regtest, keeping the
regtest exemption for private-but-valid addresses only.
- The temporary secp256k1 SecretKey locals in owner signing and owner
verification are Copy with no erasing destructor; both are now
scrubbed with non_secure_erase() right after use, matching the
provider-key derivation code.
- New test drives an ExtNetInfo entry with secondary IPv4 + IPv6
endpoints and domain/invalid entries through the summary conversion,
asserting every socket endpoint is lifted and non-socket entries are
skipped — then that a lifted secondary endpoint actually collides in
the service-uniqueness preflight.

…ardown, refuse zero platform ports
The execute forms of the registrar and service updates signed and then
broadcast directly, without the generation lifecycle protection the
prepare-then-broadcast flow gets from
core_wallet_broadcast_signed_transaction — so a wallet removed (or
re-created) between signing and the send could still publish its
transaction (#4185's shape). All three execute paths
now broadcast through a shared helper that holds
generation_payment_guard across the liveness check and the send,
abandoning and refusing when the generation is no longer live, with a
regression that removes the wallet after signing and asserts nothing
reaches the broadcaster.
The explicit-values validator also refuses Some(0) for either platform
port before funding. Not a consensus mirror: Core's
CheckProviderNetworkFields accepts a single zero platform port in a v2
payload off mainnet (only both-zero collides in its dup-ports
equality) — but no node can serve on port 0, so a supplied zero is an
input error caught before money moves.

… window, unblock Swift's cooperative executor
Three review suggestions:
- Candidate discovery derives up to 256 indices, but the managed
provider pool — and provider_masternode_txs_blocking's
derive-and-compare ownership scan with it — tracks only through
max(highest_generated + 1, 20). A rotation to a beyond-window index
would broadcast a valid key the wallet could never attribute back to
itself. The registrar assembly now refuses untracked indices before
funding, via a shared PlatformWallet::provider_operator_tracked_window
(the window constant is now shared with the ownership scan), with a
beyond-window regression test.
- Swift's providerKeyCandidates ran its synchronous FFI call in
Task.detached, which still executes on the cooperative pool and parks
a cooperative worker behind the wallet-manager lock. It now runs on a
dedicated GCD queue and resumes through a continuation — the pattern
pollQueue and the DPNS active-contests queue document.
- provider_key_candidates documents its blocking-only contract: a
Panics section for async-context callers and spawn_blocking guidance,
matching wallet_masternodes_blocking's warning.

…keep rotation externs off Swift's cooperative executor
Voting-key ownership joins against the managed provider-voting pool's
ACTUAL entries — key-wallet's voting matcher walks the pool's address
index, and hosts join persisted address rows; there is no
derive-and-compare scan like the operator side — so rotating to an
unregistered index would sign and broadcast fine and then always show
as an external voting key. The registrar assembly now refuses indices
at or beyond PlatformWallet::provider_voting_tracked_window() before
funding, with a beyond-pool regression test.
The six registrar/service prepare and execute Swift wrappers also move
off Task.detached (whose closures still run on the cooperative pool)
onto a dedicated serial GCD queue behind a shared continuation helper,
like providerKeyCandidates — kept on its own queue so a long-parked
transaction never delays a picker refresh. Resolver and buffer
lifetimes are unchanged: each body runs entirely on the queue.

The rotation commits were written against v4.2-dev. Since then the
update-service path learned Dash Core v24's version-3 payloads and
rust-dashcore moved to secp256k1 0.33 and its own BLS types.
The reactivation built from caller-supplied values now follows the same
version rules as the entry-copy path: version 3 for an evonode once V24
is active and for an entry a registrar update left with an emptied
version-3 address map, version 2 otherwise. An entry whose address map
still lists addresses is refused, since the values name one address.
The owner signature and the operator key re-encoding use the current
secp256k1 and BLS APIs. A Dash address is now always P2PKH or P2SH, so
the witness payout test checks the script rule directly.

This change adds provider-key candidate discovery, masternode registrar key rotation, and explicit service-value updates. It exposes these operations through Rust FFI and Swift APIs, and adds service endpoint and operator-key serialization metadata to masternode summaries.
Masternode summaries and tracked snapshots now include service endpoints and operator-key serialization metadata. Provider-key candidate lookup supports operator and voting keys. The wallet exposes tracked key windows and returns an error when a wallet is no longer available.
Registrar update preparation and signing packages/rs-platform-wallet/src/masternode/update_registrar.rs, packages/rs-platform-wallet/src/masternode/mod.rs
Adds registrar update preparation and execution. The flow validates owner authorization, payout address, key reuse, and collateral; signs the payload; and returns a prepared transaction or broadcasts it.
Adds preparation and execution with caller-supplied service values. The flow validates service and platform fields, checks for duplicate endpoints and node IDs, verifies fetched registration transactions, and guards broadcast against wallet-generation changes. V24 payload selection uses the latest available SPV coinbase.
Rust FFI entry points and ownership packages/rs-platform-wallet-ffi/src/masternode_update_registrar.rs, packages/rs-platform-wallet-ffi/src/masternode_update_service.rs, packages/rs-platform-wallet-ffi/src/lib.rs, packages/rs-platform-wallet-ffi/src/masternode_locator.rs
Adds FFI operations for registrar and service updates, candidate queries, and candidate memory release. Shared provider-key handling now accepts a key kind.
Swift manager APIs packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletManagerMasternodeRotation.swift
Adds candidate-query, registrar-update, and service-update methods, including prepare-only variants and input validation.
Rotating a masternode's operator key could, in a corrupted wallet state, leave the node banned until a usable operator key is provided. A caller could also submit an unusable multicast service address during reactivation. Both cases are narrow and recoverable, so the change is mergeable with owner awareness.

The title "feat(platform-wallet): rotate a masternode's keys into the wallet" matches the main change. The PR adds broadcast and prepare-only ProUpRegTx flows that rotate operator and voting keys to wallet keys, plus the follow-up service update path and provider-key candidate listing. The title names the primary change and the affected crate, and it is specific enough for a teammate scanning history. It omits the service-reactivation and candidate-listing parts, which is acceptable for a title.

The candidates query listed the first `count` provider keys, while a
registrar update refuses an operator index outside the wallet's tracked
window and a voting index outside its registered pool. A picker could
therefore offer a key the rotation then refused.
The query now stops at that window, so `count` only caps the listing.
The Swift wrapper no longer picks a window size of its own: its default
is the most one call returns.

Final validation — Phase 1 + Phase 2
Verified against head 0b581ad: three transaction-construction gaps can prevent registrar updates or required reactivation, and two new FFI workflows retain orchestration assigned to platform-wallet. Rust wallet tests and Kotlin checks pass; Swift build/tests remain pending, and the full Rust workspace suite was skipped. This was a static review; no local builds or tests were run.
Triage: critical by gpt-6.1-sol (effort low) — This large, intricate change modifies masternode key handling, owner signatures, transaction construction, and reactivation protocol-version selection in platform-wallet and its FFI/Swift boundaries, directly affecting cryptography and key management.
These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

- [BLOCKING] packages/rs-platform-wallet/src/masternode/update_registrar.rs:604-607: Ensure registrar updates have an output independently of change
This builder supplies no outputs and relies entirely on change. In pinned key-wallet, a special payload bypasses the initial NoOutputs check, and sub-dust change is omitted. A fee-covering small UTXO can therefore produce a signed ProUpRegTx with no outputs; branch-and-bound can select it even when larger UTXOs are available. Neither this finalizer nor CoreWallet::finalize_transaction rejects that shape, while Core's CheckTransaction rejects it with bad-txns-vout-empty. The sibling update-service builder already supplies a zero-value OP_RETURN and checks the invariant before signing. Apply the same protection here and cover both lone-small-UTXO and mixed-UTXO funding, including reservation release on refusal.
- [SUGGESTION] packages/rs-platform-wallet/src/masternode/update_registrar.rs:604-625: Track reusable provider-transaction construction in key-wallet
This module introduces the Core registrar construction recipe, including inputs_hash finalization and the compact owner-signature envelope; the new service-values path also implements Core payload-version and address-representation rules. The book's ownership table assigns Core transaction construction to dashpay/rust-dashcore/key-wallet, leaving platform-wallet to orchestrate. Both the pinned and current upstream revisions expose the generic payload-finalizer seam, but not a typed registrar builder that consumers can reuse. Add or link an upstream issue or PR for provider-specific construction, signing, and reusable preflight helpers. Keep wallet-key selection, network reads, lifecycle protection, and submission orchestration here. No linked tracking item in the supplied evidence covers this extraction, so it needs one before being deferred.

- [BLOCKING] packages/rs-platform-wallet/src/masternode/update_service.rs:399-401: Connect reactivation to the available V24 activation evidence
The dependency limitation stated here is false at this head: pinned rust-dashcore c9aeac0d0dcb exposes DashSpvClient::latest_coinbase() in dash-spv/src/client/queries.rs. Passing None disables the fallback already implemented in update_service_placeholder. After V24 activates, while the list still has no version-3 entries, a version-2 operator rotation can succeed and ban the node, but this required second stage builds version 2, which Core rejects with bad-protx-version-disallowed. Expose the existing observation through SpvRuntime and connect both prepare flows to the shared selection path. Respect the upstream query's freshness caveats and fail retryably when sufficient evidence is unavailable. Add production-wiring coverage for an all-legacy list with a V24 coinbase. Issue #5568 tracks the existing unban limitation, but does not resolve its introduction into this new reactivation workflow.
- [BLOCKING] packages/rs-platform-wallet/src/masternode/update_service.rs:692-700: Check every proposed version-3 endpoint for network collisions
The preflight compares only the proposed Core P2P service against other masternodes. On the version-3 evonode path, legacy_evonode_net_info also constructs Platform P2P and HTTPS endpoints at that IP. A testnet request with Core port 19999 and Platform P2P port 29999 passes this check when another masternode advertises that IP at port 29999, but the generated map contains the occupied endpoint. Core's CheckProUpServTx iterates every submitted net-info entry and rejects it with bad-protx-dup-netinfo-entry. Validate all endpoints of the final version-3 map against the other summaries before funding, preserving the exclusion of the target itself. Add tests for collisions involving each proposed platform endpoint, not just the proposed Core endpoint.
In `packages/rs-platform-wallet-ffi/src/masternode_update_registrar.rs`:
- [BLOCKING] packages/rs-platform-wallet-ffi/src/masternode_update_registrar.rs:194-207: Move wallet-index key resolution into the Rust rotation operation
This binding implements the wallet-owned rotation workflow rather than merely marshalling it. wallet_provider_secret inspects resident/watch-only/external-signable state, decides whether to invoke the mnemonic resolver, and derives the owner key; the extern then supplies the compressed-key policy. The prepare sibling repeats this assembly, and the new service-with-values externs similarly resolve operator keys themselves. The native operations accept only resolved secrets, so other consumers must reconstruct those wallet decisions. The book's 'Where code goes' and 'FFI and mobile SDKs hold no business logic' sections assign this orchestration to platform-wallet. Add library-owned wallet-index prepare/execute entry points and shared key-source resolution, accepting a Rust resolver capability whose FFI adapter only invokes the host callback. Keep resolver callbacks outside wallet guards. Reusing the pre-existing unban helper does not make its extension into these new workflows an allowed binding responsibility.
- [BLOCKING] packages/rs-platform-wallet-ffi/src/masternode_update_registrar.rs:726-732: Expose live candidate discovery as a platform-wallet operation
The new candidate-discovery workflow is completed only in this binding: it obtains the live list, decides that an unavailable list must fail rather than imply unused keys, and then invokes the derivation/join helper. The native provider_key_candidates API accepts an ordinary summary slice and does not expose that snapshot-and-derive operation or its availability precondition. Consequently, native consumers must reproduce the unknown-versus-unused decision promised by the Swift API. The book assigns mobile orchestration to platform-wallet and limits FFI to calling library operations and marshalling their results. Keep the pure slice-based helper, but add a library entry point taking the wallet and SPV context that obtains the snapshot, returns MasternodeListUnavailable when necessary, and runs blocking derivation off the async worker. The extern should call that operation.

- [SUGGESTION] packages/rs-platform-wallet/src/masternode/list.rs:32-38: Document the Rust source-compatibility break in summary construction
MasternodeListSummary is publicly exported and exhaustively constructible. Adding service_addresses and operator_key_is_legacy breaks downstream struct literals and exhaustive destructuring, even though the JSON snapshot decoder supplies compatibility defaults. The PR's Breaking Changes section currently says 'None' and discusses only the additive FFI/Swift surface. Record the Rust source break and migration guidance in that section and the maintained API documentation, including use of from_entry when a raw list entry is available and correct population of both fields otherwise. Account for this in the crate's release compatibility decision; it does not require a PlatformVersion change or the consensus-breaking '!' marker.
- [NITPICK] packages/rs-platform-wallet/src/masternode/list.rs:105: Reuse the upstream legacy-BLS predicate
The pinned MasternodeListEntry::use_legacy_bls_keys() defines legacy serialization as version == 1, while this duplicates it as version < 2. These agree for live entries today, but differ for version 0 and leave two definitions of the same property. Calling the upstream helper keeps the summary aligned with its owner without changing current network behavior.

Full checklist in the description.
…om the SPV coinbase, check every v3 endpoint
A ProUpRegTx funded by a UTXO whose surplus is below the dust limit was
built with no outputs, which Core refuses (bad-txns-vout-empty). The
builder now adds the zero-value data output the update-service builder
already carries, and the finalizer refuses an output-less transaction
before signing, releasing the reservation.
The pinned dash-spv exposes the coinbase of the newest validated
masternode list diff, so both update-service paths now read V24 from it
when the list alone cannot tell. Right after activation, while every
entry is still legacy, a reactivation after an operator rotation is
built at version 3 instead of a version 2 Core refuses.
A version-3 evonode address map registers the Platform P2P and HTTPS
endpoints next to the Core one. The values path now checks every
endpoint of the map it built against the other masternodes, not only
the Core address.
Listing key candidates against the live masternode list is now a
platform-wallet operation the FFI calls, and the legacy-BLS flag uses
the upstream predicate.

Reject service addresses that cannot identify a unicast host.
For example, 224.0.0.1:19999 passes ipv4_is_routable: none of its listed checks excludes multicast. A caller can therefore submit an unusable service endpoint during reactivation. Reject multicast and reserved 240/4 addresses before funding. Rust identifies multicast separately; the inspected Core routability predicate also does not exclude it, so Core rejection is not a safe fallback. (doc.rust-lang.org)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Verify the new operator key can sign before rotating it.
If the operator account’s stored xpub disagrees with the available seed, this public-only derivation can select and broadcast its key while funding-input signing still succeeds. The later service update requests the operator private key and rejects that mismatch. The rotation then leaves the masternode PoSe-banned without a usable stage-two key. Check private-key availability and agreement before authorizing the rotation. The provider-key derivation contract explicitly checks this mismatch only on its private-key path.

Re-review — Final validation — Phase 1 + Phase 2
At e888922, the registrar output invariant, complete endpoint preflight, live candidate discovery, legacy-BLS predicate reuse, and Rust compatibility disclosure are addressed. Static verification also confirms that the new registrar funding path can spend masternode collateral, so changes are required. Rust workspace CI remains pending; Kotlin SDK build/tests and the Swift frozen-schema check passed, and no local builds or tests were run.

Triage: critical by gpt-6.1-sol (effort low) — The large, intricate changes in packages/rs-platform-wallet/src/masternode/update_registrar.rs and update_service.rs implement key rotation and owner/operator-signed transactions, directly changing key handling and signature-critical behavior.
These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

- [BLOCKING] packages/rs-platform-wallet/src/masternode/update_registrar.rs:657-659: Keep masternode collateral out of registrar fee selection
This new operation funds registrar fees from SEND_FUNDING_SOURCES without collateral protection. In pinned rust-dashcore c9aeac0d0dcb, TransactionBuilder::fund_from offers every unreserved funding-account UTXO, and processing a ProRegTx does not automatically lock its collateral. CoreWallet::finalize_transaction adds no exclusion. A wallet whose only funding coin backs masternode A can therefore spend it to rotate tracked masternode B, returning change but ending A's registration. The target's collateral-script preflight checks key/script reuse, not funding inputs belonging to other registrations. The owning-layer fix is already merged in dashpay/rust-dashcore#1391 and present in the supplied default checkout; dashpay/platform#5890 supplies persistence and tracked-registration integration. Make this funding path depend on that protection rather than introducing another local selector, and add a registrar regression case where only collateral is available: funding must fail without spending it.

Issue being fixed or feature implemented
A masternode owner whose owner key is in the wallet, but whose operator or voting key is not, cannot move those keys into the wallet from the phone.
This PR carries #4519 forward onto the current
v5.1-dev. It holds the 13 commits of #4519 by QuantumExplorer, cherry-picked unchanged apart from three import conflicts, plus one commit that ports them to the current base. #4519 was written againstv4.2-devand no longer merges.What was done?
From #4519 (unchanged in behaviour):
provider_key_candidateslists the wallet's operator or voting keys by index, joined against the masternode list, so a key picker can show which keys are unused network-wide.The port commit (
fix(platform-wallet): port the key rotation to v5.1-dev):Limits that remain:
v5.1-dev. feat(platform-wallet): keep masternode collateral out of coin selection #5890 adds that protection for all of them; this path funds through the same call and inherits it.masternode_update_service.rs. Moving that key-source choice intoplatform-walletis tracked for all callers in refactor(platform-wallet): own the key-source choice natively #5740.How Has This Been Tested?
