… sync This change simplifies the SPV client by removing the separate watch manager infrastructure and directly integrating wallet functionality into the sync process. Changes: - Remove WatchManager and related test files - Remove WatchItem types from types.rs - Pass wallet reference directly to SequentialSyncManager - Simplify filter checking to use wallet's built-in check_compact_filter - Clean up client module to remove watch-related complexity - Download full filter range instead of limited recent blocks - Streamline mempool filter and filter sync logic This refactoring reduces code complexity and better leverages the wallet's existing filter checking capabilities. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

343-346: Fix underflow when computing tip heights with empty segments.If
valid_count == 0or a filter segment has zero headers,... - 1underflows (u32::MAX). Guard before subtracting and skip updating the tip in that case.Apply this diff:
- let tip_height = - segment_id * HEADERS_PER_SEGMENT + segment.valid_count as u32 - 1; - *self.cached_tip_height.write().await = Some(tip_height); + if segment.valid_count > 0 { + let tip_height = + segment_id * HEADERS_PER_SEGMENT + (segment.valid_count as u32) - 1; + *self.cached_tip_height.write().await = Some(tip_height); + } else { + tracing::debug!( + "Segment {} has zero valid headers; not updating tip height", + segment_id + ); + }- let storage_index = - segment_id * HEADERS_PER_SEGMENT + segment.filter_headers.len() as u32 - 1; + let storage_index_base = segment_id * HEADERS_PER_SEGMENT; + if segment.filter_headers.is_empty() { + tracing::debug!( + "Filter segment {} has zero headers; not updating filter tip", + segment_id + ); + return Ok(()); + } + let storage_index = + storage_index_base + (segment.filter_headers.len() as u32) - 1;Also applies to: 350-367
451-466: Avoid concurrent double-writes on eviction; don’t sync-save segments in Saving state.Evict paths save synchronously whenever state != Clean. If state == Saving, a background write may be in-flight, causing racy, interleaved writes to the same file.
Apply this diff:
- // Save if dirty or saving before evicting - do it synchronously to ensure data consistency - if oldest_segment.state != SegmentState::Clean { + // Save only if Dirty; skip if Saving to avoid concurrent double-writes + if oldest_segment.state == SegmentState::Dirty { tracing::debug!( "Synchronously saving segment {} before eviction (state: {:?})", oldest_segment.segment_id, oldest_segment.state ); let segment_path = self .base_path .join(format!("headers/segment_{:04}.dat", oldest_segment.segment_id)); save_segment_to_disk(&segment_path, &oldest_segment.headers).await?; tracing::debug!( "Successfully saved segment {} to disk", oldest_segment.segment_id ); + } else if oldest_segment.state == SegmentState::Saving { + tracing::trace!( + "Evicting header segment {} in Saving state; skipping sync save", + oldest_segment.segment_id + ); }- // Save if dirty or saving before evicting - do it synchronously to ensure data consistency - if oldest_segment.state != SegmentState::Clean { + // Save only if Dirty; skip if Saving to avoid concurrent double-writes + if oldest_segment.state == SegmentState::Dirty { tracing::trace!( "Synchronously saving filter segment {} before eviction (state: {:?})", oldest_segment.segment_id, oldest_segment.state ); let segment_path = self .base_path .join(format!("filters/filter_segment_{:04}.dat", oldest_segment.segment_id)); save_filter_segment_to_disk(&segment_path, &oldest_segment.filter_headers).await?; tracing::debug!( "Successfully saved filter segment {} to disk", oldest_segment.segment_id ); + } else if oldest_segment.state == SegmentState::Saving { + tracing::trace!( + "Evicting filter segment {} in Saving state; skipping sync save", + oldest_segment.segment_id + ); }Also applies to: 526-541

1623-1639: Complete the wallet integration for filter matching.The
check_filters_for_matchesmethod currently returns an empty Vec with a TODO comment. This is a critical function for the wallet integration. The empty implementation could cause downstream issues where filter matches are expected.Would you like me to help implement the wallet integration for this method or create an issue to track this work?
1772-1811: Remove unnecessary TODO comment and clarify method behavior.The
download_and_check_filtermethod has a TODO comment but the implementation appears incomplete. The method always returnsfalseregardless of the filter check result, which could be misleading.Apply this diff to clarify the method's behavior:
pub async fn download_and_check_filter( &mut self, block_hash: BlockHash, network: &mut N, storage: &mut S, ) -> SyncResult<bool> { - // TODO: Will check with wallet once integrated - // Get the block height for this hash by scanning headers let header_tip_height = storage .get_tip_height() .await .map_err(|e| SyncError::Storage(format!("Failed to get header tip height: {}", e)))? .unwrap_or(0); let height = self .find_height_for_block_hash(&block_hash, storage, 0, header_tip_height) .await? .ok_or_else(|| { SyncError::Validation(format!( "Cannot find height for block {} - header not found", block_hash )) })?; tracing::info!( - "📥 Requesting compact filter for block {} at height {}", + "📥 Requesting compact filter for block {} at height {} (check will be performed when filter is received)", block_hash, - height + height ); // Request the compact filter using getcfilters self.request_filters(network, height, block_hash).await?; // Note: The actual filter checking will happen when we receive the CFilter message - // This method just initiates the download. The client will need to handle the response. + // This method just initiates the download and always returns false. + // The actual match result will be determined when the CFilter message is processed. - Ok(false) // Return false for now, will be updated when we process the response + Ok(false) // Always returns false - actual matching happens asynchronously }
2304-2336: Remove unused parameters in spawn_filter_processor.The function has unused parameters that trigger compiler warnings. Since wallet integration is pending, these parameters might be used in the future, but for now they should either be prefixed with underscore or removed.
Apply this diff to fix the warnings:
pub fn spawn_filter_processor( - network_message_sender: mpsc::Sender<NetworkMessage>, - processing_thread_requests: std::sync::Arc< + _network_message_sender: mpsc::Sender<NetworkMessage>, + _processing_thread_requests: std::sync::Arc< std::sync::Mutex<std::collections::HashSet<BlockHash>>, >, stats: std::sync::Arc<tokio::sync::RwLock<crate::types::SpvStats>>, ) -> FilterNotificationSender {dash-spv/src/sync/sequential/mod.rs (1)
1899-1899: Remove unused parameter in handle_post_sync_cfilter.The
networkparameter is unused and triggers a compiler warning.Apply this diff to fix the warning:
async fn handle_post_sync_cfilter( &mut self, cfilter: dashcore::network::message_filter::CFilter, - network: &mut N, + _network: &mut N, storage: &mut S, ) -> SyncResult<()> {dash-spv/src/client/mod.rs (2)
2178-2191: Use declarations occur after use within the same function.
Version and CompactTarget are used before they’re imported; move the imports earlier or fully-qualify.Apply either:
- Move the
use dashcore::{ block::{Header as BlockHeader, Version}, pow::CompactTarget };to the top of the function, before first usage; or- Fully-qualify here:
- version: Version::from_consensus(536870912), + version: dashcore::block::Version::from_consensus(536870912), ... - bits: CompactTarget::from_consensus( + bits: dashcore::pow::CompactTarget::from_consensus(And remove the late
useif fully-qualifying:- use dashcore::{ - block::{Header as BlockHeader, Version}, - pow::CompactTarget, - }; - use dashcore_hashes::Hash; + use dashcore_hashes::Hash;Also applies to: 2258-2263
2386-2388: Fix E0107: SequentialSyncManager now has 3 generics.
This test helper signature is the CI error source.Apply:
- pub fn sync_manager_mut(&mut self) -> &mut SequentialSyncManager<S, N> { + pub fn sync_manager_mut(&mut self) -> &mut SequentialSyncManager<S, N, W> { &mut self.sync_manager }
🧹 Nitpick comments (31)
dash-spv/src/storage/disk.rs (2)
867-871: Use storage index for periodic save cadence checks to keep cadence stable across checkpoints.Using blockchain height makes cadence dependent on sync_base_height. Prefer storage index.
Apply this diff:
- if headers.len() >= 1000 || blockchain_height % 1000 == 0 { + if headers.len() >= 1000 || final_storage_index % 1000 == 0 { self.save_dirty_segments().await?; }- if headers.len() >= 1000 || next_height % 1000 == 0 { + if headers.len() >= 1000 || final_height % 1000 == 0 { self.save_dirty_segments().await?; }- if headers.len() >= 1000 || next_blockchain_height % 1000 == 0 { + if headers.len() >= 1000 + || (next_blockchain_height.saturating_sub(sync_base_height)) % 1000 == 0 + { self.save_dirty_segments().await?; - } + }Also applies to: 1076-1080, 1247-1250
171-171: Use tracing::error! instead of eprintln! for consistency.Keep logging unified with tracing.
- eprintln!("Failed to save segment {}: {}", segment_id, e); + tracing::error!("Failed to save segment {}: {}", segment_id, e);- eprintln!("Failed to save filter segment {}: {}", segment_id, e); + tracing::error!("Failed to save filter segment {}: {}", segment_id, e);- eprintln!("Failed to save index: {}", e); + tracing::error!("Failed to save index: {}", e);Also applies to: 191-191, 209-209
dash-spv/src/client/status_display.rs (1)
88-93: Don’t swallow storage errors when reading filter tip; log and default.Currently
.ok().flatten().unwrap_or(0)hides failures. Log at least warn to aid ops.- let storage = self.storage.lock().await; - let filter_header_height = - storage.get_filter_tip_height().await.ok().flatten().unwrap_or(0); - drop(storage); + let storage = self.storage.lock().await; + let filter_header_height = match storage.get_filter_tip_height().await { + Ok(Some(h)) => h, + Ok(None) => 0, + Err(e) => { + tracing::warn!("Failed to read filter tip height from storage: {}", e); + 0 + } + }; + drop(storage);Apply the same pattern in both UI and non-UI paths.
Also applies to: 131-135, 182-186

529-531: Update docstring to reflect wallet-driven matching (no “watch items”).- /// Number of compact filters that matched watch items. + /// Number of compact filters that matched wallet-tracked items.dash-spv/src/client/config.rs (2)
7-10: Remove unused imports to keep clippy clean.Address and ScriptBuf are unused and trigger warnings. Trim the import to only Network.
-use dashcore::{Address, Network, ScriptBuf}; +use dashcore::Network;
375-416: Consider using a typed error for validate().Returning Result<(), String> makes error handling brittle and violates the codebase guideline to use thiserror-based types.
I recommend introducing a ConfigValidationError (thiserror) and changing validate() to return Result<(), ConfigValidationError>, propagating it where mapped into SpvError::Config.
dash-spv/src/client/message_handler.rs (2)
27-33: Tighten W bounds to match downstream requirements.SequentialSyncManager stores Arc<RwLock> and its methods often require Send + Sync + 'static. Add these bounds here to avoid surprising compile errors when calling sync_manager methods.
-impl< - 'a, - S: StorageManager + Send + Sync + 'static, - N: NetworkManager + Send + Sync + 'static, - W: WalletInterface, - > MessageHandler<'a, S, N, W> +impl< + 'a, + S: StorageManager + Send + Sync + 'static, + N: NetworkManager + Send + Sync + 'static, + W: WalletInterface + Send + Sync + 'static, + > MessageHandler<'a, S, N, W>
353-369: Avoid double-awaiting should_fetch_transaction().The current code awaits should_fetch_transaction twice. Compute once and reuse.
- if self.config.fetch_mempool_transactions - && filter.should_fetch_transaction(&txid).await - { + let should_fetch = self.config.fetch_mempool_transactions + && filter.should_fetch_transaction(&txid).await; + if should_fetch { tracing::info!("📥 Requesting transaction {}", txid); // Request the transaction let getdata = NetworkMessage::GetData(vec![item]); if let Err(e) = self.network.send_message(getdata).await { tracing::error!("Failed to request transaction {}: {}", txid, e); } } else { tracing::debug!("Not fetching transaction {} (fetch_mempool_transactions={}, should_fetch={})", txid, self.config.fetch_mempool_transactions, - filter.should_fetch_transaction(&txid).await + should_fetch ); }dash-spv/src/client/block_processor.rs (4)
3-3: Drop unused HashMap import (clippy warning).HashMap is unused after removing watch-item logic.
-use std::collections::{HashMap, HashSet}; +use std::collections::HashSet;
9-11: Prune unused AddressBalance import.AddressBalance is only referenced by an unused method below. Removing both keeps warnings at zero.
-use crate::types::{AddressBalance, SpvEvent, SpvStats}; +use crate::types::{SpvEvent, SpvStats};
577-587: Remove unused get_address_balance() helper.This method is unused and triggers warnings. Remove it (or gate with #[cfg(test)] if kept for tests).
- /// Get the balance for a specific address. - async fn get_address_balance(&self, _address: &dashcore::Address) -> Result<AddressBalance> { - // WalletInterface doesn't expose per-address balance - // Return empty balance for now - Ok(AddressBalance { - confirmed: dashcore::Amount::from_sat(0), - unconfirmed: dashcore::Amount::from_sat(0), - pending: dashcore::Amount::from_sat(0), - pending_instant: dashcore::Amount::from_sat(0), - }) - }
615-619: Stat name likely incorrect (requested vs processed).Updating blocks_requested after processing a block is confusing; consider a separate counter (e.g., blocks_state_updated) or increment blocks_requested only on request dispatch.
dash-spv/src/main.rs (2)
397-442: Disable --add-example-addresses on mainnet to avoid privacy/UX surprises.Currently it logs mainnet example addresses. Guard this flag to non-mainnet networks.
- if matches.get_flag("add-example-addresses") { - let network = config.network; + if matches.get_flag("add-example-addresses") { + let network = config.network; + if network == dashcore::Network::Dash { + tracing::warn!("--add-example-addresses is disabled on mainnet; ignoring."); + } else { let example_addresses = match network { dashcore::Network::Dash => vec![ // Some example mainnet addresses (these are from block explorers/faucets) "Xesjop7V9xLndFMgZoCrckJ5ZPgJdJFbA3", // Crowdnode ], dashcore::Network::Testnet => vec![ // Testnet addresses "yNEr8u4Kx8PTH9A9G3P7NwkJRmqFD7tKSj", // Example testnet address "yMGqjKTqr2HKKV6zqSg5vTPQUzJNt72h8h", // Another testnet example ], dashcore::Network::Regtest => vec![ // Regtest addresses (these would be from local testing) "yQ9J8qK3nNW8JL8h5T6tB3VZwwH9h5T6tB", // Example regtest address "yeRZBWYfeNE4yVUHV4ZLs83Ppn9aMRH57A", // Another regtest example ], _ => vec![], }; for addr_str in example_addresses { // ... } - } + } + }
444-459: Avoid logging full wallet addresses on mainnet (privacy).Suppress or redact addresses on mainnet to prevent PII leakage in logs.
- if !monitored.is_empty() { - tracing::info!("Wallet monitoring {} addresses:", monitored.len()); - for (i, addr) in monitored.iter().take(10).enumerate() { - tracing::info!(" {}: {}", i + 1, addr); - } + if !monitored.is_empty() { + tracing::info!("Wallet monitoring {} addresses:", monitored.len()); + if config.network == dashcore::Network::Dash { + tracing::info!(" (address list suppressed on mainnet for privacy)"); + } else { + for (i, addr) in monitored.iter().take(10).enumerate() { + tracing::info!(" {}: {}", i + 1, addr); + } + }dash-spv/src/client/filter_sync.rs (2)
72-75: Derive earliest height from wallet state.Defaulting to last 100 blocks is fine short-term, but integrating wallet birth height or creation time (ClientConfig.wallet_creation_time) will avoid missing early matches.
97-117: Clamp requested count to available tip range.When count overshoots the available range from start to tip, clamp it to prevent unnecessary queueing and confusing logs.
- let start = start_height.unwrap_or(filter_tip_height.saturating_sub(99)); - let num_blocks = count.unwrap_or(100); + let start = start_height.unwrap_or(filter_tip_height.saturating_sub(99)); + let num_blocks = count.unwrap_or(100); + let available = filter_tip_height.saturating_sub(start).saturating_add(1); + let num_blocks = num_blocks.min(available);dash-spv/src/sync/filters.rs (3)
325-327: Simplify redundant blockchain-to-storage height conversions.There are multiple instances where
blockchain_to_storage_heightis called and the result is immediately stored in a variable that's only used once. Consider inlining these conversions for better readability.For example, simplify this pattern:
-let storage_height = - self.blockchain_to_storage_height(next_batch_end_height); -match storage.get_header(storage_height).await { +match storage.get_header(self.blockchain_to_storage_height(next_batch_end_height)).await {Also applies to: 409-411, 420-422, 523-525, 681-692, 746-752, 802-806
1990-1993: Improve code formatting for better readability.The checkpoint filter header storage code has poor formatting that makes it harder to read.
Apply this diff to improve formatting:
if self.sync_base_height > 0 && start_height == self.sync_base_height + 1 && current_filter_tip < self.sync_base_height { // Store the previous_filter_header as the filter header for the checkpoint block let checkpoint_header = vec![cfheaders.previous_filter_header]; - storage.store_filter_headers(&checkpoint_header).await.map_err( - |e| { - SyncError::Storage(format!( - "Failed to store checkpoint filter header: {}", - e - )) - }, - )?; + storage + .store_filter_headers(&checkpoint_header) + .await + .map_err(|e| { + SyncError::Storage(format!("Failed to store checkpoint filter header: {}", e)) + })?;Also applies to: 1996-2003
2338-2473: Consider removing large commented-out code blocks.There are extensive commented-out code sections for wallet integration. These should either be removed and tracked in an issue, or converted to proper documentation explaining the future integration plan.
Consider either:
- Remove the commented code and create a GitHub issue with the implementation details
- Convert to a documentation comment explaining the planned wallet integration approach
This will keep the codebase cleaner while preserving the implementation strategy.
dash-spv/src/sync/sequential/mod.rs (1)
1917-1920: Track wallet integration TODO appropriately.The TODO comment indicates incomplete wallet integration for post-sync filter checking. This should be tracked properly.
The post-sync filter checking is currently disabled. Would you like me to:
- Help implement the wallet integration for this path?
- Create a GitHub issue to track this work?
- Add more detailed documentation about what needs to be done?
dash-spv/src/client/mod.rs (11)
104-107: Return an Arc clone instead of &Arc to avoid leaking the field’s reference type.
Returning a cloned Arc is idiomatic and more ergonomic for callers (can be moved into tasks).Apply:
- pub fn wallet(&self) -> &Arc<RwLock<W>> { - &self.wallet - } + pub fn wallet(&self) -> Arc<RwLock<W>> { + self.wallet.clone() + }
211-214: Remove unnecessary mut; address clippy warning.
Variable is never mutated after initialization.Apply:
- let mut sync_manager = - SequentialSyncManager::new(&config, received_filter_heights, wallet.clone()) - .map_err(SpvError::Sync)?; + let sync_manager = + SequentialSyncManager::new(&config, received_filter_heights, wallet.clone()) + .map_err(SpvError::Sync)?;
270-279: MempoolFilter initialized with empty address set – likely ineffective.
Until wallet integration populates addresses, filtering won’t match anything.Consider centralizing via update_mempool_filter() and wiring it to wallet address updates. Minimal change now:
- if self.config.enable_mempool_tracking { - // TODO: Get monitored addresses from wallet - self.mempool_filter = Some(Arc::new(MempoolFilter::new( + if self.config.enable_mempool_tracking { + // Initialize from wallet (will be empty until wallet integration is complete) + self.update_mempool_filter().await; + if self.mempool_filter.is_none() { + self.mempool_filter = Some(Arc::new(MempoolFilter::new( self.config.mempool_strategy, Duration::from_secs(self.config.recent_send_window_secs), self.config.max_mempool_transactions, self.mempool_state.clone(), - vec![], // Will be populated from wallet's monitored addresses + vec![], self.config.network, - ))); + ))); + }Follow-up: does WalletInterface expose a read-only “monitored_addresses() -> Vec
”? If yes, we can implement it inside update_mempool_filter().
451-459: Same as above: enable_mempool_tracking initializes filter with empty addresses.
Call update_mempool_filter() instead for a single source of truth.Apply:
- if self.mempool_filter.is_none() { - // TODO: Get monitored addresses from wallet - self.mempool_filter = Some(Arc::new(MempoolFilter::new( + if self.mempool_filter.is_none() { + self.update_mempool_filter().await; + if self.mempool_filter.is_none() { + self.mempool_filter = Some(Arc::new(MempoolFilter::new( self.config.mempool_strategy, Duration::from_secs(self.config.recent_send_window_secs), self.config.max_mempool_transactions, self.mempool_state.clone(), - vec![], // Will be populated from wallet's monitored addresses + vec![], self.config.network, - ))); + ))); + }
556-569: update_mempool_filter() still builds an empty filter.
Wire this to wallet as soon as WalletInterface exposes addresses; otherwise, document the limitation explicitly.Proposed structure when wallet API is available:
let addresses = { let w = self.wallet.read().await; // e.g., w.monitored_addresses(self.config.network) Vec::<dashcore::Address>::new() }; self.mempool_filter = Some(Arc::new(MempoolFilter::new( self.config.mempool_strategy, Duration::from_secs(self.config.recent_send_window_secs), self.config.max_mempool_transactions, self.mempool_state.clone(), addresses, self.config.network, )));
1191-1193: Balance reporting TODO.
Once wallet integration lands, use wallet’s address set and balances to report changes.I can wire this to the wallet interface once the address/balance APIs are confirmed.
1218-1221: Returning Ok(empty) may mask missing wallet integration.
Prefer a clear error to avoid silent misbehavior.Apply:
- // TODO: Get balances from wallet instead of tracking separately - // Will be implemented when wallet integration is complete - Ok(std::collections::HashMap::new()) + Err(SpvError::Config( + "get_all_balances is handled by the external wallet; call the wallet API instead" + .to_string(), + ))
14-14: Remove unused import (HashSet).
Cleans clippy warning.Apply:
- use std::collections::HashSet;
939-951: Duplicate timeout checks share the same last_timeout_check timer.
Both blocks gate on the same Instant; only the second resets it. Consider consolidating to a single check to avoid skewed cadence.
1234-1245: Downcast to MultiPeerNetworkManager ties API to a concrete impl.
If possible, expose a disconnect_peer on NetworkManager to avoid downcasting.
1235-1238: Two peer count APIs (peer_count and get_peer_count).
Redundant; consider keeping only one to simplify public surface.

680-711: I/O offloading is solid; error mapping looks good.Blocking file I/O is correctly offloaded with spawn_blocking and mapped to domain errors.
Also applies to: 713-744, 746-759
1951-1997: Great coverage for checkpoint indexing and index rebuild.The tests validate storage-index mapping, reverse index, and rebuild behavior across instances.
1303-1327: get_filter_header semantics are already aligned across backendsBoth implementations interpret the
heightparameter as the blockchain height, internally mapping it to whatever storage index is appropriate:
- MemoryStorageManager stores every header starting at genesis (height 0), so calling
get_filter_header(h)simply doesself.filter_headers[h as usize](vector index = blockchain height).- DiskStorageManager must account for a non-zero
sync_base_height, so it converts the blockchain height into an internal index viablockchain_height – sync_base_heightand then reads the entry at that index.Because both treat the argument as a blockchain height—and simply perform the necessary offset only within the disk backend—there is no mismatch in the public API. Renaming the parameter or changing the trait signature to “storage_index” would break or confuse clients that expect to pass a blockchain height.
If anything, you may optionally clarify the trait documentation to explicitly state “height is the blockchain height; implementations map to internal storage indices as needed.” Beyond that, no code changes are required here.
Likely an incorrect or invalid review comment.

178-183: Avoid holding write lock across await if possible.wallet.check_compact_filter is awaited while a write lock is held. If that method awaits internally or re-enters wallet locks, this can deadlock or reduce concurrency.

336-338: Good improvement to filter download range calculation.Using
header_sync.get_sync_base_height().max(1)ensures proper handling of checkpoint-based sync and prevents downloading filters for blocks before the sync base.
1307-1330: Excellent wallet integration for filter checking!The implementation properly:
- Acquires a write lock on the wallet
- Calls the wallet's filter checking method with appropriate parameters
- Drops the lock after use
- Requests the full block when a match is found
The use of
deref_mut()to get the mutable reference is correct.
1445-1470: Well-implemented wallet-based block processing.The block processing correctly:
- Gets the block height from storage
- Calls
wallet.process_blockwith all necessary parameters- Logs relevant transaction information appropriately
- Properly manages the wallet lock lifecycle

25-26: Import of SyncProgress looks good.
Aligns with new return type usage.
75-75: SequentialSyncManager now requires 3 generics (S, N, W).
Good change; remember to fix the test helper signature below (see Line 2386 comment).

read the mnemonic from an environment variable (DASH_SPV_MNEMONIC) using a

Do not write filter headers “below” sync_base_height; current code misindexes.
When next_blockchain_height < sync_base_height, the code warns but still uses next_blockchain_height as a storage index, corrupting layout. Skip storing that header (or return an error) to avoid out-of-range writes.
Apply this restructuring:
- // Convert blockchain height to storage index
- let storage_index = if sync_base_height > 0 {
- // For checkpoint sync, storage index is relative to sync_base_height
- if next_blockchain_height >= sync_base_height {
- next_blockchain_height - sync_base_height
- } else {
- // This shouldn't happen in normal operation
- tracing::warn!(
- "Attempting to store filter header at height {} below sync_base_height {}",

396-419: Confirm wallet block‐processing pathIt appears that
handle_block_messageis only invoked while the sync manager is in theDownloadingBlocksphase—but inexecute_current_phasethis phase immediately transitions out with the “No blocks to download” reason, before any blocks are requested or downloaded. As a result, the wallet’sprocess_block(inhandle_block_message) may never be called, and all block processing would instead fall through to the client’s block processor.Please verify and adjust as needed:
- In

transition_to_next_phase(..., "No blocks to download")immediately- In the same file around lines 402–418,

handle_block_message(lines 1437–1500) invokeswallet.process_blockbut never forwards the block to the client processor- Block requests (

In dash-spv/src/sync/sequential/mod.rs around lines 1917 to 1920, replace the
placeholder debug and TODO with a real wallet-based compact-filter check: call
the wallet's check_compact_filter (or equivalent) to match filters against the
wallet state instead of using watch items, wire any necessary wallet reference
into this sync context, and handle the wallet response (match/miss) to include
matching transactions in post-sync processing; remove the debug message and
ensure proper error handling and tests cover cases where wallet matching changes
which txs are considered relevant.
