Suggested in bitcoin#26933 (comment) This RPC should be safe but still experimental - interface may change, not all features (e.g. package RBF) are implemented, etc. If a miner wants to expose this to people, they can effectively use "package relay" before the p2p changes are implemented. However, please note **this is not package relay**; transactions submitted this way will not relay to other nodes if the feerates are below their mempool min fee. Users should put this behind some kind of rate limit or permissions.

**: # CodeRabbit AI Review Instructions for Dash BackportsYour Role
You are reviewing Bitcoin Core backports to Dash Core. Your ONLY job is to validate that the Dash commit faithfully represents the original Bitcoin commit with minimal, necessary adaptations.
Critical Validation Rules
1. File Operations Must Match (AUTO-REJECT if violated)
- If Bitcoin modifies an existing file → Dash MUST modify (not create new)
- If Bitcoin creates a new file → Dash creates
- If Bitcoin deletes a file → Dash deletes
- Common failure: Bitcoin modifies keys.txt, Dash creates new file with 58 keys
2. Size Ratio Check (80-150% of Bitcoin)
- Count functional lines changed (exclude comments/whitespace)
- Dash changes should be 80-150% of Bitcoin's size
- Red flag: 2-line Bitcoin fix becoming 150+ lines in Dash
3. No Scope Creep
- Reject if you see: "TODO:", "FIXME:", "while we're here", "also fix"
- No unrelated refactoring or style changes
- Only Bitcoin's intended changes + minimal Dash adaptations
4. Bitcoin-Specific Code Detection
- Auto-reject witness/segwit code:
msg_wtxidrelay,MSG_WTX, witness imports- Auto-reject RBF (replace-by-fee) functionality
- Note: PSBT is supported in Dash (don't flag)
5. Mandatory Adaptations Only
bitcoin→dashin strings/pathsBitcoin→Dashin user-facing text- Port numbers: 8332→9998 (RPC), 8333→9999 (P2P)
- Hardcoded test values specific to Dash
- No other changes unless absolutely required
6. Completeness Check
- All files changed in Bitcoin must be present
- Extra files need clear justification (Dash-specific compatibility)
- Missing files = incomplete backport
Review Process
- First: Check file operations match exactly
- Second: Calculate size ratio
- Third: Scan for scope creep patterns
- Fourth: Detect Bitcoin-specific code
- Fifth: Verify all changes are minimal adaptations

Learning: In Dash backports from Bitcoin Core, including necessary compilation fixes (such as API compatibility changes like UniValue get_int() → getInt<int>()) alongside the core backport is standard and expected practice. These compatibility fixes ensure the backported code compiles in Dash's evolved codebase while preserving Bitcoin's original functionality and intent.

🔇 Additional comments (6)
src/policy/packages.h (1)
62-65: LGTM - Clean function declaration with clear documentation.The addition of
IsChildWithParentsTreeis well-documented and serves the specific purpose of enforcing stricter package topology validation for the submitpackage RPC. The function signature and documentation are consistent with the implementation.src/test/txpackage_tests.cpp (3)
148-148: LGTM - Appropriate test coverage for simple parent-child case.The test correctly validates that
IsChildWithParentsTreereturns true for a valid tree structure with one parent and one child.
174-174: LGTM - Validates multiple parents scenario.The test appropriately checks that
IsChildWithParentsTreereturns true when there are multiple parents (24) with one child, where no parents depend on each other.
207-207: LGTM - Tests rejection of parent dependencies.The test correctly validates that
IsChildWithParentsTreereturns false when parents depend on each other, which violates the tree structure requirement. This is the key differentiator fromIsChildWithParents.src/policy/packages.cpp (1)
85-98: LGTM - Well-structured implementation with clear logic.The
IsChildWithParentsTreefunction is correctly implemented:
- Efficient validation: First validates basic child-with-parents structure before checking tree constraints
- Clear algorithm: Collects parent transaction IDs and ensures no parent depends on another parent
- Good performance: Uses
unordered_setfor O(1) lookup operations- Readable code: Clear variable names and helpful comments
The implementation faithfully enforces the tree structure requirement for package validation.
src/validation.cpp (1)
1200-1219: LGTM! Clean backport of Bitcoin Core package feerate validation.This is a faithful implementation of Bitcoin Core's aggregate package feerate checking logic. The code correctly:
- Calculates total virtual size and modified fees across all transactions in the package
- Validates the aggregate feerate against mempool minimum requirements
- Provides comprehensive documentation explaining the aggregate nature and limitations
- Uses existing
CheckFeeRatevalidation infrastructure- Returns appropriate error states for policy violations
The implementation is focused solely on the intended Bitcoin Core functionality without scope creep.

Bitcoin-specific RBF constant imported
MAX_BIP125_RBF_SEQUENCE is a Bitcoin-specific constant for Replace-By-Fee functionality. RBF is not supported in Dash.
🏁 Script executed:
#!/bin/bash
# Check if RBF constants or functionality exists in Dash
rg -i "rbf|bip125|replace.by.fee" src/ test/Length of output: 6564
Use Dash’s BIP125_SEQUENCE_NUMBER in rpc_packages.py instead of MAX_BIP125_RBF_SEQUENCE
The constant MAX_BIP125_RBF_SEQUENCE is Bitcoin-specific and not defined in Dash. Dash already defines BIP125_SEQUENCE_NUMBER in test_framework/messages.py, so update the import and usages accordingly.
• In test/functional/rpc_packages.py:
- Remove the import of
MAX_BIP125_RBF_SEQUENCE - Add
from test_framework.messages import BIP125_SEQUENCE_NUMBER - Replace every occurrence of

**: # CodeRabbit AI Review Instructions for Dash BackportsYour Role
You are reviewing Bitcoin Core backports to Dash Core. Your ONLY job is to validate that the Dash commit faithfully represents the original Bitcoin commit with minimal, necessary adaptations.
Critical Validation Rules
1. File Operations Must Match (AUTO-REJECT if violated)
- If Bitcoin modifies an existing file → Dash MUST modify (not create new)
- If Bitcoin creates a new file → Dash creates
- If Bitcoin deletes a file → Dash deletes
- Common failure: Bitcoin modifies keys.txt, Dash creates new file with 58 keys
2. Size Ratio Check (80-150% of Bitcoin)
- Count functional lines changed (exclude comments/whitespace)
- Dash changes should be 80-150% of Bitcoin's size
- Red flag: 2-line Bitcoin fix becoming 150+ lines in Dash
3. No Scope Creep
- Reject if you see: "TODO:", "FIXME:", "while we're here", "also fix"
- No unrelated refactoring or style changes
- Only Bitcoin's intended changes + minimal Dash adaptations
4. Bitcoin-Specific Code Detection
- Auto-reject witness/segwit code:
msg_wtxidrelay,MSG_WTX, witness imports- Auto-reject RBF (replace-by-fee) functionality
- Note: PSBT is supported in Dash (don't flag)
5. Mandatory Adaptations Only
bitcoin→dashin strings/pathsBitcoin→Dashin user-facing text- Port numbers: 8332→9998 (RPC), 8333→9999 (P2P)
- Hardcoded test values specific to Dash
- No other changes unless absolutely required
6. Completeness Check
- All files changed in Bitcoin must be present
- Extra files need clear justification (Dash-specific compatibility)
- Missing files = incomplete backport
Review Process
- First: Check file operations match exactly
- Second: Calculate size ratio
- Third: Scan for scope creep patterns
- Fourth: Detect Bitcoin-specific code
- Fifth: Verify all changes are minimal adaptations

Learning: During multiple verification attempts of Bitcoin Core commit 06d469c26b backport to Dash PR #566, DashCoreAutoGuix consistently identified scope creep in interface_usdt_utxocache.py where additional pruning test functionality was added beyond the original Bitcoin commit. The user provided comprehensive fixes including both scope creep removal and missing mempool test file additions, but couldn't push due to authentication restrictions. The scope creep fix was identified as the priority to resolve CI failures.

Learning: In Dash backports from Bitcoin Core, including necessary compilation fixes (such as API compatibility changes like UniValue get_int() → getInt<int>()) alongside the core backport is standard and expected practice. These compatibility fixes ensure the backported code compiles in Dash's evolved codebase while preserving Bitcoin's original functionality and intent.

471-598: LGTM! Submitpackage RPC properly adapted for DashThe implementation correctly:
- Uses
GetHash()instead ofGetWitnessHash()throughout- Keys transaction results by txid instead of wtxid
- Removes BIP 141 references from documentation
- Properly notes that effective-feerate is not available in Dash implementation
The backport faithfully preserves the submitpackage functionality while adapting it to Dash's transaction model.
