refactor(interfaces): expose typed provider transaction operations#7600PastaPastaPasta wants to merge 14 commits into
Conversation
WalkthroughThe PR introduces typed provider-transaction interfaces and a shared service for registration, updates, submission, and revocation. RPC commands now parse typed requests and delegate transaction handling through node and wallet interfaces. Provider network validation is centralized. Wallets can derive, reserve, recover, and persist mnemonic-backed masternode operator BLS keys. Wallet funding, signing, and coin-lock results are exposed through interfaces. Tests cover provider validation, operator-key lifecycle behavior, persistence, concurrency, and collateral-lock failures. Estimated code review effort: 5 (Critical) | ~120 minutes Mergeability Score: 🟡 Moderate · up to The refactor introduces typed provider transaction paths, but funded collateral selection can choose a same-value change output instead of the requested destination, potentially producing an incorrect or rejected provider transaction. Merge readiness therefore requires fixing or explicitly accepting this bounded correctness risk, with localized validation-message and repository-tracking follow-ups.

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.

gpt-5.6-sol— general (completed) - Verifier:
gpt-5.6-sol— verifier - Sonnet/Opus: not run (Phase 2 disabled — temporary Codex/Sol-only final)

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).
Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] src/evo/providertx_service.cpp:488-491: Match funded collateral by destination and amount
`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. The transaction can then register collateral paid to the fee-source change destination rather than the destination in `FundProviderCollateral`.

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 is stacked on #7594. Until that PR merges, GitHub's aggregate diff also
contains its wallet-derived operator-key commits. The P-specific change is
commit
348958f6d080and can be reviewed directly with thestack-only comparison.

How Has This Been Tested?

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.
