WalkthroughThe changes introduce new configuration options documented in the README and reflected in the configuration struct. Enhancements to transaction broadcasting include improved logging, error handling, and a new parallel broadcasting method. Transaction handling is made more robust through an error queue and advanced retry logic. Several blockchain-related modules are updated with new address prefixes, modified message types, and refined peer discovery. The application's entry point is streamlined to operate solely in registry mode, with reduced configuration complexity and improved modularity. Changes

175-175:Details
❓ Verification inconclusive
Dramatic increase in num_multisend limit (from 10 to 3000).
This change significantly increases the number of transactions in a single multisend operation from 10 to 3000, which could have substantial performance implications:
- Larger transaction sizes may exceed blockchain limits
- Higher gas costs per transaction
- Potential memory consumption issues
- Longer processing times
Consider making this value configurable or adding validation to ensure it doesn't exceed chain-specific limits. Perhaps add a comment explaining why 3000 was chosen as an appropriate value.

Attention: Verify multisend limit increase and validate its impact
The change in
lib/chainregistry/cli.go(line 175) from a multisend limit of 10 to 3000 is a significant increase that could have major performance and resource implications. There are concerns that:
- Transaction Limits: Handling 3000 transactions in one multisend could exceed blockchain-imposed limits.
- Gas Costs: A larger batch size may lead to considerably higher gas costs.
- Memory Consumption: Without explicit safeguards, processing such large batches may strain memory resources.
- Processing Time: Significantly more transactions per operation might prolong processing times.
Our initial grep searches did not reveal any specific transaction size validation or memory management logic directly related to multisend operations. Given these points, please verify that:
- The 3000-limit is intentional and acceptable within your chain’s performance and resource constraints.
- There is adequate validation or fallback logic in place to handle edge cases where the multisend batch size might be problematic.
Good-to-have: Consider making the multisend limit configurable or adding detailed documentation and validations to prevent exceeding chain-specific limits.
modules/bank/multisend_distributor.go (1)
64-67: Consider bounding frequent refresh intervals.Refetching RPC endpoints more frequently (every time
m.rpcIndex % 10 == 0) can help discover more non-registry nodes but may also increase overhead. Introduce a configurable upper bound or cooldown to avoid excessive peer lookups during periods of high throughput.broadcast/broadcast.go (1)
229-603: ParallelBroadcast function significantly increases throughput.The worker-pool approach, concurrency factor (
len(healthyNodes) * 6), and per-position batch logic can significantly boost performance. Verify that:
- The concurrency level aligns with node capabilities to avoid memory or CPU saturation.
- The node reassignment logic handles fallback nodes consistently under heavy load.
- The short (3-second) timeout on transactions is sufficient in environments with unpredictable latencies.
Beyond that, the design is consistent with high-throughput broadcasting objectives.
lib/peerdiscovery/discovery.go (3)
30-31: Ensure naming consistency across node sets and slices.You’ve introduced
registryNodesas a map andnonRegistryNodesas a slice. This is perfectly valid—just be aware that if you need to prevent duplicates of non-registry nodes in the future, using amap[string]boolfor both might simplify checks for existence.
54-60: Validate endpoints before marking them as registry nodes.Currently, each passed-in
initialEndpointis normalized, then unconditionally added toregistryNodesif not empty. Consider a more explicit or robust validation (e.g., verifying the address format). This might reduce potential edge cases of incorrectly formed endpoints being designated as “registry” ones.Also applies to: 62-62
186-193: Lock usage for concurrency is correct, but watch for duplicates in non-registry nodes.You hold
pd.resultsMutex.Lock()before appending topd.nonRegistryNodes, which is safe. However, if you want to avoid listing the same IP multiple times (should the node appear again), consider checking if it’s already innonRegistryNodesbefore appending.modes/registry/registry.go (6)
106-107: Inline messaging is helpful for user feedback.Printing the “Running chain test” message and then calling
runChainTestkeep the user informed. Consider adding details or next steps if the chain test fails for extended diagnostics.
293-293: Balancing status message.The message “Checking account balances…” is consistent with the flow. Consider enabling optional verbosity if you eventually have too many logs.
302-310: Toggling the visualizer.The conditional logic for
enableVizlooks correct, with proper initialization and logging. Potentially ensurebroadcast.InitVisualizerhandles repeated inits gracefully, although it appears safe.
1105-1108: Resource cleanup and visualizer stop.Your addition of a final message (“Cleaning up resources…”) and optional
broadcast.StopVisualizer()is a neat finishing touch. Make sure any subsequent code or goroutines referencing the distributor or visualizer handle their disposal gracefully.
1143-1169:printConfigmethod for debugging.Perfect for clarity and user support. For large or sensitive configs, you may consider toggling certain fields or redacting them.
1171-1208:RunPositioningintroduction.
- Good job generating accounts and assigning them to nodes.
- The load-balancing approach to RPCs is beneficial.
- Check if the user-specified node assignment might conflict with your round-robin logic.
All in all, a helpful new function.
broadcast/transaction.go (7)
8-10: New imports added.Imports for logging (“log”), sorting (“sort”), and additional references (e.g., signing types) are consistent with your new functionality. Consider a structured logger for more advanced introspection, especially around broadcast scenarios.
Also applies to: 16-16, 24-24
75-86:AddErrorandGetErrorStringmethods are straightforward.Appending error messages and returning them joined as a single string is fine for pattern searching. If user volumes grow, watch out for potential memory usage from concatenation, but the limit of 10 messages helps.
Also applies to: 88-95
129-179: Fallback logic for missingto_address.Automating a random “to_address” from CSV can be helpful. Just ensure:
- The CSV loading is thread-safe if multiple goroutines call this concurrently.
- The generated address is valid and not frequently repeated if you want to test broad coverage.
799-812: Robust retrieval of client context with retries.This code snippet attempts up to three times to get a valid
clientCtx. That’s a useful measure for transient network issues. Consider exponential backoff if you notice frequent short failures.
1000-1049: Multiple regex attempts for extracting sequence.You systematically try multiple patterns to parse the correct sequence. This is thorough. Just ensure you keep these patterns in sync if chain upgrades alter the error messages.
1182-1224: Performance tracking post-broadcast.Updating node performance metrics, success rates, and average latency is beneficial for load-balancing. The branching for success/failure is well laid out. Consider storing a slightly shorter rolling average if you need quicker adaptation for ephemeral network conditions.
1432-1466: Node assignment and performance metrics.Your new logic that leverages nodePerformance stats for success/failure count, average latency, and “health” flags is well-conceived. It’s a robust approach for distributing load. If your environment has flapping nodes, consider a small grace period before marking a node “unhealthy.”

lib/account.go (5)
44-44: Added "atone" to the list of known address prefixes.The addition of the "atone" prefix expands chain compatibility, specifically for AtomOne chain.
183-184: Enhanced logging for address selection.Adding this log statement improves observability when selecting addresses. This is particularly helpful for debugging and understanding the application's behavior.
188-188: Improved error message with context for random number generation.Better error message using fmt.Errorf with error wrapping provides more context about what operation failed.
197-203: Added robust error handling for address conversion.These changes properly handle errors from the Bech32ifyAddressBytes function with a descriptive error message and add a helpful success log message to improve debugging.
207-208: Enhanced error message with detailed context.The improved error message now includes the initialization state, load attempt status, and count of addresses, which provides more context for debugging when no addresses are available.
broadcast/utils.go (6)
77-91: Added robust URL cleanup for node endpoints.This enhancement removes suffixes like "(broadcaster 1)" or "(node 2)" from URLs to ensure proper format for RPC connections. The implementation correctly uses regular expressions to handle the pattern matching and provides helpful logs.
93-105: Added URL validation with descriptive error messages.This code properly validates the URL structure using the standard url.Parse function and checks for required URL components (scheme and host). The error messages are clear and include the problematic parts of the URL.
108-108: Using cleaned baseURL for RPC client creation.Consistency in using the cleaned baseURL for RPC client creation ensures proper connection handling.
123-123: Updated NodeURI to use the cleaned base URL.This change ensures consistency in the client context by using the same cleaned URL throughout.
148-152: Enhanced error message with node URI information.Including the nodeURI in the error message provides better context for troubleshooting connection errors.
157-157: Improved error message for account info retrieval.Including the nodeURI in the account info error provides better context for troubleshooting.

modules/bank/multisend_distributor.go (4)
83-86: Extended discovery timeout appears useful.Allowing 45 seconds for more thorough peer discovery is an improvement. Ensure that any upstream callers or workflows can handle this extended blocking time.
92-110: Good prioritization of non-registry endpoints.Prioritizing non-registry nodes and updating the RPC list if new endpoints are found effectively diversifies node usage. Logging the count and a sample of non-registry nodes is helpful for diagnostics.
115-120: No issues with returning the seed counter.Incrementing and returning
m.seedCounteris straightforward. Just ensure any concurrency usage outside this lock scope does not require the seed in sync with other global counters.
123-125: Peer discovery accessor is well-structured.Providing a public getter for the
peerDiscoveryinstance is a clean approach, especially if other parts of the codebase require direct read-only access.broadcast/broadcast.go (4)
6-8: New imports are appropriate.The additions of
log,strings, andsyncare consistent with the new parallel broadcasting and enhanced logging functionality.
87-119: Enhanced logging for transaction start and errors.Capturing start times (
startTimeandtxStartTime) and logging truncated error messages reduces noise while retaining useful diagnostics. This clarity is a helpful improvement for debugging complex broadcasting failures.
126-154: Robust error handling with response codes.Detecting specific error codes (like 32 for sequence mismatch or 13 for insufficient fees) is a good step toward proactive recovery. Logging these selectively to reduce spam is also beneficial.
177-188: Batch completion metrics are well-reported.Aggregating success rates, throughput, and time aids in quickly assessing performance. This structured logging is valuable for high-volume broadcasts.
lib/peerdiscovery/discovery.go (3)
43-48: Constructor looks good.You properly instantiate the new fields in the
PeerDiscoverystruct. InitializingregistryNodesandnonRegistryNodeshere clarifies the intended usage. No issues spotted.
435-460: Prioritized endpoints approach is intuitive.Collecting and returning non-registry nodes first, then appending the rest, is straightforward. Be aware that if
nonRegistryNodesgrows large, the appended endpoints could become hidden far in the results. If you need advanced ordering logic, you might consider weighting or consolidated deduplication. For now, this is quite clear.
462-470: Straightforward retrieval of non-registry nodes.This method properly returns a copy of
pd.nonRegistryNodes, preventing external modification of the internal slice. The read-lock usage is correct.modes/registry/registry.go (8)
36-36: New parameter to toggle visualizer.Adding
enableViz booltoRunRegistryModeis clear and aligns with the rest of the updates. No issues spotted.
228-228: Expanded function signature for enhanced control.
enableViz boolinrunChainTestis a logical extension for toggling the visualizer. Double-check that all internal calls are updated accordingly if other referencing code exists.
238-245: Default channel usage is helpful, but consider user override.You provide a fallback with
"channel-0". This can prevent confusion when no channel is configured. Just ensure that the user or calling code can override this easily in future expansions.
286-287: Accounts generation logging.These lines add clarity for the user. No issues here.
299-300: Assigning chainID from config.Setting
chainID := config.Chainis straightforward. Double-check that your existing error handling covers the case whereconfig.Chainis truly invalid or missing, to avoid mismatched states.
312-316: Launcher flow is clear.Initializing the distributor and launching the “transaction broadcasters” is well structured. If
distributorinitialization fails for some reason, consider short-circuiting instead of continuing into the broadcast step.
324-324: NewlaunchTransactionBroadcastersfunction.
- Parameter grouping is logical, though you might consider consolidating them into a struct if the signature grows further.
- The call to
broadcast.ParallelBroadcastis straightforward, capturing successes/failures.
No blocking issues found.Also applies to: 326-331, 333-339
1119-1141:updateGasConfigapproach is solid.Using a switch to optimize gas settings per message type is well-organized. If new message types emerge, ensure you add a default fallback. Also watch that large batch scenarios (like massive multisends) are not under-gassed.
broadcast/transaction.go (12)
43-46: Expanded error patterns for fees and sequence.Capturing varied error message formats is helpful for robust error handling. Ensure you remain aware of potential performance overhead if the regex checks become more numerous or the error logs are large.
Also applies to: 48-53, 55-56
63-66:ErrorQueueaddition with concurrency safety.Using a RWMutex for storing and retrieving recent error messages is a good approach. The queue capacity limit helps prevent unbounded growth. Looks well-structured.
Also applies to: 70-73
218-226: Logging of bank send message.You log the newly created
MsgSenddetails, including the from/to addresses and amount. This is good for debugging. Consider adjusting the logging level if these become too verbose in production.
238-246: IBC transfer message creation.This is a clean approach for building IBC transfer messages. The fallback for the default port and channel is consistent with the new pattern you use in other parts of the code. Same caution applies: if concurrency is high, ensure no global states conflict (though it seems local).
Also applies to: 249-255, 256-275
744-765: Sequence tracking logic upon building the transaction.You override the incoming sequence with a local node’s
LastSequenceif it’s higher, then default to1if zero. This dynamic approach can reduce mismatch errors but watch for potential edge cases if the chain’s actual sequence is lower. Retries help mitigate that risk.
844-854: Apply node-specific fee buffer.Your dynamic fee adjustment can help mitigate “insufficient fee” errors. Watch that you don’t overshoot drastically if the node repeatedly returns large required fees. Logging is already in place to track it, so that’s good.
Also applies to: 858-859
959-970: Insufficient fee error detection.You capture “insufficient fee” in broadcast responses. The logic to update the local node’s minimum fee and incorporate a buffer is a solid approach. Keep an eye on potential chain-wide changes in fees that might differ from your local adjustments.
Also applies to: 977-980
965-968: Sequence mismatch handling.Your layout to “wait a bit and retry with refreshed sequence from chain” is prudent. This helps align with the node’s last known mempool state.
1055-1091: Extracting required fees from errors.All your variations—“spendable is smaller than…,” “required: …,” “fee < minimum”—are handled carefully. If your chain adds other fee errors, you can build in further patterns. Looks good for now.
1152-1174: BroadcastTx wrappers with custom error processing.Sync, async, and block modes funnel into
ProcessBroadcastResponse. This unifies your error-handling logic nicely. Great for reducing code duplication.Also applies to: 1177-1177
1227-1354:SendTxenhancements.
- The code chooses either the account’s assigned node or picks a best-performing node from
GetHealthyNodesOnly.- The fallback logic for sequence mismatch triggers
retryWithCorrectedSequence.- Overall approach is thorough, though be mindful that repeatedly incrementing sequences can eventually skip valid sequence numbers if the node reported them out of sync.
No immediate red flags, just usage caution.
1369-1421:retryWithCorrectedSequenceflow is sound.Grabbing the combined errors from the
ErrorQueueand extracting an updated sequence or fee for the retry helps reduce friction from ephemeral mismatch conditions. This approach can mask truly invalid states if the node or chain is heavily out of sync, so keep an eye on logs.main.go (3)
17-19: Minimal CLI usageUsing the standard library
flagpackage to parse the--vizflag keeps the CLI straightforward and easy to maintain.
21-22: Clear log statementLogging the zero-configuration approach explicitly communicates the new operational mode to users, minimizing confusion about the missing config file options.
24-26: Robust error handlingExiting on unexpected errors ensures that issues are reported immediately, preventing partial or undefined states in a CLI application.

🧩 Analysis chain
Significant configuration change from bank_send to ibc_transfer.
This change alters the default transaction type from local transfers to cross-chain transfers. Make sure this is an intentional change as it has several implications:
- Not all chains may support IBC transfers
- IBC transfers require specific channel configuration
- Gas costs and requirements differ between message types
🏁 Script executed:
#!/bin/bash
# Verify if this change is properly documented and if other parts of the code handle IBC transfer correctly
# Check if IBC transfer requirements are documented in README
echo "Checking for IBC documentation..."
grep -i "ibc" README.md
# Check if channel configuration is properly handled for IBC transfers
echo "Checking for channel handling in code..."
grep -r "source_channel" --include="*.go" .
grep -r "destination_channel" --include="*.go" .Length of output: 551
Action Required: Confirm IBC Transfer Channel Configuration
It’s been noted that the default transaction type has switched from bank_send to ibc_transfer, which has significant implications. While we found handling for source_channel (in types/types.go and broadcast/broadcast.go), there’s no evidence of any configuration or usage of a destination_channel. Additionally, the README only briefly references IBC (in the context of "IBC Security Testing") without detailing channel setup.
- Verify that the omission of a
destination_channelconfiguration is intentional. - Ensure that any necessary IBC channel configurations (including destination channels) are implemented where required.
- Update documentation to clearly explain the new IBC transfer requirements, including any adjustments for gas costs and channel configurations.

Added new BalanceFunds configuration option.
This change adds a new boolean configuration option to automatically balance funds between accounts. This is a useful feature for managing funds across multiple accounts in testing or operational scenarios.
Consider adding clear documentation about what "automatically balance funds" means in practice - does it distribute funds equally? Is there a threshold? How frequently does the balancing occur?
🏁 Script executed:

# Verify that this new configuration option is properly documented and implemented
# Check if the new option is documented in README

BalanceFunds option verified; improve documentation clarity
The new BalanceFunds configuration option is correctly defined in types/types.go, documented in the README, and its usage is evident in modes/registry/registry.go. However, please consider expanding the README documentation to clarify what "automatically balance funds" entails (e.g., whether it distributes funds equally, what thresholds apply, and how often the balancing occurs).
