WalkthroughThe PR adds typed provider-transaction interfaces and a shared provider transaction service. It centralizes network validation, funding, signing, consensus checks, broadcasting, and collateral locking. RPC handlers now parse typed requests and delegate operations through node and wallet interfaces. Special transaction validation uses shared network-field checks. Tests cover capabilities, network validation, wallet locks, and RPC collateral failures. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The refactor changes provider transaction funding and signing, but the current funding path may carry signatures from a non-special transaction into a special-transaction template, causing provider registrations or updates to fail unless every caller reliably re-signs. This requires fixing or explicitly accepting the signing-flow risk before merge. Sequence Diagram(s)sequenceDiagram

Final validation — Codex/Sol only (Phase 2 disabled)
The typed provider-transaction refactor appears to preserve the existing RPC boundary and transaction behavior, with no blocking correctness issue identified. One repository-maintenance omission remains: four new Dash-specific C++ files are absent from the manifest that drives Dash-specific cppcheck coverage.
Source: reviewer backend model gpt-5.6-sol; final verifier backend model gpt-5.6-sol. Orchestration-only: openclaw-agent/cliproxy/gpt-5.6-sol (not reviewer evidence).
Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

`test/lint/lint-cppcheck-dash.py` obtains its inputs exclusively by passing the patterns from `test/util/data/non-backported.txt` to `git ls-files`. Directly evaluating those patterns confirms that this new Dash-specific header is excluded, as are `src/interfaces/masternode_operator.h`, `src/wallet/masternode_operator.h`, and `src/wallet/test/masternode_operator_tests.cpp`. The new `src/evo/providertx_service.{cpp,h}` files are already covered by the existing `src/evo/*` patterns. Add the four uncovered paths, or suitable narrowly scoped patterns, so the new Dash-specific code receives the required cppcheck coverage.

Preliminary review — Codex only
The typed provider-transaction refactor has one blocking correctness issue: funded registrations can identify a same-value change output as the collateral and therefore register an output sent to the wrong destination. The previous cppcheck-manifest finding remains partially unresolved because three new Dash-specific masternode-operator files are still outside the manifest.
Source: reviewer backend model gpt-5.6-sol; final verifier backend model gpt-5.6-sol. Orchestration-only: openclaw-agent/cliproxy/gpt-5.6-sol (not reviewer evidence).

`fundTransaction()` invokes `CreateTransaction` with `RANDOM_CHANGE_POSITION`, which BIP69-sorts the resulting outputs. If the change output has the same value as the required 1000/4000 DASH collateral and sorts before the requested collateral output, this amount-only search assigns `collateralOutpoint.n` to the change output.

Fixed in 80c30b8: the funded-collateral lookup now matches both the collateral amount and the requested destination's script, so an equal-value change output can no longer be selected. (The amount-only scan was inherited verbatim from the previous rpc/evo.cpp implementation, but this service is the right place to harden it.)

Preliminary review — Codex only
The typed provider-transaction refactor still has two blocking correctness issues: funded registrations can reference a same-value change output instead of the requested collateral destination, and a persistent coin-lock failure can return FAILED while leaving the coin locked in memory. The earlier non-backported manifest concern is outdated after this PR was retargeted and the masternode-operator files were removed from the exact head.

Final validation — Codex/Sol only (Phase 2 disabled)
At the exact head, both previously blocking defects are fixed: funded collateral is matched by amount and destination script, and failed persistent coin-lock acquisition rolls back the in-memory lock. One in-scope test-coverage suggestion remains because the persistent database-failure rollback path is not exercised.
Source: reviewer backend models: gpt-5.6-sol (general), gpt-5.6-sol (dash-core-commit-history); final verifier backend model: gpt-5.6-sol. Orchestration-only: openclaw-agent/cliproxy/gpt-5.6-sol (not reviewer evidence).
Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

Issue being fixed or feature implemented
The Qt masternode registration and maintenance work needs to build, sign, and
broadcast normal/Evo provider transactions without treating the RPC server as a
GUI transport. Calling
Node::executeRpcwith method strings,UniValuearguments, and wallet URI routing would make the GUI depend on RPC parsing and
error conventions and would duplicate no domain boundary at all.
This PR extracts the existing normal/Evo ProTx implementation into a typed
service shared by RPC and future GUI callers. It is the backend prerequisite for
the registration UI extracted from PastaPastaPasta/dash#68.
This PR now targets
developdirectly and contains only its own commits; it isno longer stacked on #7594, and the GitHub diff is the full reviewable change.

Breaking Changes
No RPC method or successful result shape changes. Incompletely signed ProTx
inputs now return the existing wallet error category instead of yielding a
partial transaction or deferring failure to broadcast. This is intentional:
the typed success type guarantees a fully signed transaction. Additionally,
protx update_serviceon a masternode with no extractable default fee sourcenow returns an explicit "specify feeSourceAddress" parameter error instead of
an internal error.
