7-8: Consider grouping export statementsFor better readability and maintainability, consider grouping all
pub usestatements together. This can make it easier for developers to quickly see all the public exports in one place.Here's a suggested reorganization:
mod aggregator; mod app_config; mod ciphernode; +pub use app_config::*; pub use aggregator::*; pub use ciphernode::*; - -pub use app_config::*;tests/basic_integration/lib/ciphernode_config.yaml (1)
2-3: Consider adding more chain-specific informationWhile the current configuration is sufficient for basic functionality, consider adding more chain-specific information to enhance clarity and support future features. This could include:
chain_id: The numeric identifier for the Hardhat network (typically 31337 for local networks).currency_symbol: The native currency symbol (e.g., "ETH" for Ethereum).block_time: The average block time for the network.Example:
- name: "hardhat" chain_id: 31337 currency_symbol: "ETH" block_time: 2 rpc_url: "ws://localhost:8545"This additional information could be useful for chain-specific logic and improve the overall robustness of the configuration.
packages/ciphernode/evm/src/lib.rs (1)
1-6: Approve new module structure with a suggestion for documentation.The new module structure aligns well with the PR objective of improving maintainability through vertical slicing of the EVM module. The granular approach to handling different smart contracts (Enclave.sol, CiphernodeRegistry.sol, NaiveRegistryFilter.sol) is a good step towards better organization.
Consider adding a brief comment above each module declaration to explain its purpose and responsibilities. This will help developers understand the new structure more quickly.
Example:
/// Handles interactions with the CiphernodeRegistry smart contract mod ciphernode_registry_sol; /// Manages core Enclave contract functionality mod enclave_sol; /// Provides read operations for the Enclave contract mod enclave_sol_reader; /// Provides write operations for the Enclave contract mod enclave_sol_writer; /// Contains shared utility functions for EVM operations pub mod helpers; /// Implements filtering logic for the registry mod registry_filter_sol;packages/ciphernode/enclave/src/lib.rs (1)
4-13: LGTM: Well-structured configuration loading function.The
load_configfunction is well-implemented, using theconfigcrate effectively and providing proper error handling. It correctly loads the configuration from the specified file and deserializes it into anAppConfiginstance.Consider additional error handling for empty or malformed config files.
While the function handles the case where the config file doesn't exist, it might be beneficial to add specific error handling for cases where the file exists but is empty or malformed. This could provide more informative error messages to users.
Consider adding a custom error type that wraps
ConfigErrorand provides more context:pub enum ConfigLoadError { FileNotFound(ConfigError), EmptyFile, MalformedContent(ConfigError), DeserializationError(ConfigError), } pub fn load_config(config_path: &str) -> Result<AppConfig, ConfigLoadError> { let config_builder = Config::builder() .add_source(File::with_name(&config_path).required(true)) .build() .map_err(ConfigLoadError::FileNotFound)?; if config_builder.cache.is_empty() { return Err(ConfigLoadError::EmptyFile); } let config: AppConfig = config_builder .try_deserialize() .map_err(ConfigLoadError::DeserializationError)?; Ok(config) }Address TODO: Implement Ethereum address validation.
The TODO comment suggests that Ethereum address validation is needed. This is an important security consideration.
Would you like assistance in implementing Ethereum address validation? We could add a validation step after deserialization to ensure all Ethereum addresses in the
AppConfigare valid.packages/ciphernode/enclave/Cargo.toml (1)
16-16: LGTM! Consider using workspace-level dependency management.The addition of the
configcrate (v0.14.0) is a good choice for improving configuration management in the project. This aligns well with the PR objectives, particularly addressing the configuration needs outlined in Issue #134.Consider moving this dependency to the workspace-level
Cargo.tomlfile if it's going to be used across multiple packages. This would ensure consistent versioning across the project. You can then reference it in this file using:config = { workspace = true }This approach would be consistent with how other dependencies like
alloyandclapare managed in this file.packages/ciphernode/enclave_node/src/app_config.rs (5)
1-3: Remove unused importThe
HashMapimport fromstd::collectionsis not used in this file. Consider removing it to keep the imports clean and relevant.Apply this diff to remove the unused import:
-use std::collections::HashMap; use serde::Deserialize;
5-10: LGTM! Consider adding documentationThe
ContractAddressesstruct is well-defined and appropriate for holding contract addresses. The use ofStringtype for addresses and derivingDebugandDeserializetraits are correct choices for configuration purposes.Consider adding documentation comments to describe the purpose of this struct and its fields. This will improve code readability and maintainability. For example:
/// Holds the addresses of various contracts used in the application #[derive(Debug, Deserialize)] pub struct ContractAddresses { /// Address of the Enclave contract pub enclave: String, /// Address of the Ciphernode Registry contract pub ciphernode_registry: String, /// Address of the Filter Registry contract pub filter_registry: String, }
12-18: LGTM! Consider adding documentation and planning for future enhancementsThe
ChainConfigstruct is well-defined for chain-specific configuration. The use ofOption<bool>for theenabledfield is a good choice, allowing for explicit enable/disable or default behavior.
Consider adding documentation comments to describe the purpose of this struct and its fields, similar to the suggestion for
ContractAddresses.Regarding the comment about multiple RPC URLs:
pub rpc_url: String, // We may need multiple per chain for redundancy at a later pointIt's good to plan for future enhancements. Consider creating a GitHub issue to track this potential feature, ensuring it's not forgotten and can be properly designed when needed.
Would you like me to create a GitHub issue for tracking the potential need for multiple RPC URLs per chain?
20-23: LGTM! Consider adding documentation and potential enhancementsThe
AppConfigstruct is well-defined for holding multiple chain configurations. UsingVec<ChainConfig>allows for a flexible number of chain configurations, which aligns well with the multichain objectives of this PR.
Consider adding documentation comments to describe the purpose of this struct and its field, similar to the previous suggestions.
For future enhancements, you might want to consider:
- Adding a version field to track configuration schema versions.
- Including global application settings that are not chain-specific.
Here's an example of how you might implement these suggestions:
/// Represents the overall application configuration #[derive(Debug, Deserialize)] pub struct AppConfig { /// Version of the configuration schema pub version: String, /// Configurations for individual blockchain chains pub chains: Vec<ChainConfig>, /// Global application settings pub global_settings: GlobalSettings, } /// Global application settings #[derive(Debug, Deserialize)] pub struct GlobalSettings { // Add global settings here }Would you like me to propose these enhancements in a separate GitHub issue for future consideration?
1-23: Overall implementation aligns well with PR objectivesThe
app_config.rsfile introduces a well-structured configuration system that aligns closely with the PR objectives and addresses key points from the linked issues:
- It supports multichain functionality by allowing multiple
ChainConfiginstances inAppConfig, addressing the requirement mentioned in Issue Support multiple chains #75.- The configuration structure, using serde's
Deserialize, facilitates easy management of both sensitive and non-sensitive data, as discussed in Issue Sort out configuration #134.- The modular design with separate structs for
ContractAddressesandChainConfigcontributes to the improved maintainability goal mentioned in Issue Vertically slice evm module for better maintainability #140.This implementation provides a solid foundation for the multichain support and configuration management required by the project. It's flexible enough to accommodate future enhancements while meeting the current needs outlined in the PR objectives.
As the project evolves, consider the following architectural considerations:
- Implement a configuration validation mechanism to ensure all required fields are properly set before the application starts.
- Plan for backwards compatibility as the configuration structure evolves over time.
- Consider implementing a configuration migration system for seamless upgrades in the future.
packages/ciphernode/evm/src/enclave_sol.rs (3)
9-9: LGTM: Consider if state is needed for EnclaveSol.The
EnclaveSolstruct is defined as an empty struct, which suggests it's being used as a namespace for associated functions. This aligns with the PR objective of simplifying the evm package. However, consider if any state (e.g., configuration data) should be associated with this struct to enhance its functionality and reduce parameter passing in methods.
10-21: LGTM: Consider adding chain_id parameter and explicit error handling.The
attachmethod effectively sets up both reading and writing capabilities for the Enclave contract. The use ofArc<PrivateKeySigner>aligns well with the PR objective of securely handling sensitive data.However, consider the following improvements:
- Add a
chain_idparameter to align with the PR objective of internal handling ofchain_id.- Implement more explicit error handling to provide clearer context in case of failures.
Here's a suggested modification:
pub async fn attach( bus: Addr<EventBus>, rpc_url: &str, contract_address: &str, signer: Arc<PrivateKeySigner>, chain_id: u64, ) -> Result<()> { EnclaveSolReader::attach(bus.clone(), rpc_url, contract_address, chain_id) .await .map_err(|e| anyhow::anyhow!("Failed to attach EnclaveSolReader: {}", e))?; EnclaveSolWriter::attach(bus, rpc_url, contract_address, signer, chain_id) .await .map_err(|e| anyhow::anyhow!("Failed to attach EnclaveSolWriter: {}", e))?; Ok(()) }This modification adds the
chain_idparameter and provides more context in error messages.
1-21: Overall assessment: Good implementation with room for minor improvements.The
EnclaveSolstruct and itsattachmethod provide a clean interface for setting up Enclave contract interactions, aligning well with the PR objectives of simplifying the evm package and enhancing event handling. The implementation effectively modularizes the functionality, separating reader and writer concerns.Key strengths:
- Clear separation of concerns between reader and writer.
- Use of
Arc<PrivateKeySigner>for secure handling of sensitive data.- Asynchronous implementation for efficient I/O operations.
Suggestions for improvement:
- Consider adding state to the
EnclaveSolstruct if it would reduce parameter passing.- Add a
chain_idparameter to theattachmethod for better multichain support.- Implement more explicit error handling for clearer debugging.
These improvements would further align the implementation with the PR objectives, particularly in terms of multichain support and error handling.
packages/ciphernode/router/src/committee_meta.rs (1)
21-31: LGTM: Proper integration ofsrc_chain_id, consider error handling.The changes correctly propagate the
src_chain_idfrom theE3Requestedevent to theCommitteeMetastruct, which is in line with the PR objectives. The implementation is consistent and maintains the existing pattern.Consider adding error handling in case the
E3Requestedevent doesn't containsrc_chain_id. This could be done by using the?operator or amatchstatement to handle potentialNonevalues. For example:let E3Requested { threshold_m, seed, src_chain_id, .. } = data else { log::error!("E3Requested event is missing required fields"); return; };This would make the code more robust against potential changes in the
E3Requestedstruct.packages/ciphernode/enclave/src/main.rs (2)
23-27: LGTM: Improved Args struct with centralized configurationThe changes to the
Argsstruct align well with the PR objectives:
- Making the struct and
addressfield public improves integration possibilities.- Adding a
configfield and removing specific contract fields centralizes configuration management, supporting the multi-chain functionality.These changes enhance flexibility and maintainability.
Consider adding a doc comment to the
Argsstruct to explain its purpose and the expected format of theconfigfield. This would improve code documentation:/// Command-line arguments for the Ciphernode application /// /// The `config` field should point to a JSON or YAML file containing /// chain-specific configurations. #[derive(Parser, Debug)] #[command(author, version, about, long_about = None)] pub struct Args { // ... existing fields ... }
37-37: LGTM: Centralized configuration loading implementedThe use of
load_config(&args.config)?successfully implements the centralized configuration loading as outlined in the PR objectives. This approach is more flexible and maintainable than the previous hardcoded contract address parsing.Consider adding a more descriptive error message to improve debugging in case of configuration loading failures:
let config = load_config(&args.config).map_err(|e| format!("Failed to load config from {}: {}", args.config, e))?;This will provide more context about which file failed to load and why.
packages/ciphernode/router/src/hooks.rs (2)
73-73: LGTM! Consider updating the method signature.The addition of
meta.src_chain_idwhen instantiatingPlaintextAggregatoris correct and aligns with the PR objectives for multichain support.Consider updating the method signature of
LazyPlaintextAggregator::createto include themetaparameter, ensuring consistency with the internal usage:pub fn create(bus: Addr<EventBus>, sortition: Addr<Sortition>, meta: &Meta) -> EventHookThis change would make the method signature more explicit about its dependencies and improve code clarity.
107-107: LGTM! Consider updating the method signature.The addition of
meta.src_chain_idwhen instantiatingPublicKeyAggregatoris correct and aligns with the PR objectives for multichain support.Similar to the suggestion for
LazyPlaintextAggregator, consider updating the method signature ofLazyPublicKeyAggregator::createto include themetaparameter:pub fn create(bus: Addr<EventBus>, sortition: Addr<Sortition>, meta: &Meta) -> EventHookThis change would make the method signature more explicit about its dependencies and improve code clarity.
tests/basic_integration/test.sh (2)
113-113: Approve config file usage for aggregator ciphernodeThe update to use a config file for launching the aggregator ciphernode is consistent with the changes made to regular ciphernode launch commands. This change supports the PR's goal of simplifying configuration management and enables multichain support.
Consider moving the
PRIVATE_KEYto the config file for better security and consistency. If this is not feasible, ensure that thePRIVATE_KEYenvironment variable is properly secured and not logged or exposed in any way.
Line range hint
114-130: Approve addition of waiton-files functionThe new
waiton-filesfunction is a valuable addition to the script. It enhances robustness by ensuring all necessary files exist before proceeding, and includes a timeout mechanism to prevent infinite waiting.Consider adding a progress indicator to provide feedback during long waits:
while true; do all_exist=true for file in "$@"; do if [ ! -f "$file" ]; then all_exist=false break fi done if $all_exist; then break fi if [ $(($(date +%s) - start_time)) -ge $timeout ]; then echo "Timeout waiting for files: $@" >&2 return 1 fi + echo -n "." >&2 # Add a progress indicator sleep 1 done +echo "" >&2 # Add a newline after the progress indicatorpackages/ciphernode/aggregator/src/plaintext_aggregator.rs (1)
41-41: Consider adding error handling forsrc_chain_idWhile the changes to include
src_chain_idare correct and consistent with the PR objectives, consider adding error handling or validation for thesrc_chain_idvalue. This could include:
- Checking if the
src_chain_idis valid or supported at the beginning of thenewmethod.- Adding a method to validate or update the
src_chain_idif needed.- Implementing error handling in case of mismatched chain IDs during event processing.
These additions would enhance the robustness of the multi-chain support.
Would you like assistance in implementing these error handling suggestions?
Also applies to: 53-53, 60-60, 189-189
packages/ciphernode/tests/tests/test_aggregation_and_decryption.rs (4)
123-123: LGTM:src_chain_idfield added to events, but consider parameterizing the chain ID.The addition of the
src_chain_idfield to theE3RequestedandPublicKeyAggregatedevents aligns with the PR objective of supporting multiple chains. The test assertions have been correctly updated to include this new field.However, the
src_chain_idis hardcoded to 1 in both instances. Consider parameterizing this value to make the test more flexible and to potentially test multiple chain scenarios in the future.You could introduce a constant or a test parameter for the chain ID:
const TEST_CHAIN_ID: u64 = 1; // Then use it in the event creation and assertions src_chain_id: TEST_CHAIN_ID,This approach would make it easier to modify the chain ID for different test scenarios in the future.
Also applies to: 145-183
284-284: LGTM:src_chain_idadded toPlaintextAggregatedevents in P2P forwarding test.The
PlaintextAggregatedevents used in the P2P forwarding test have been correctly updated to include thesrc_chain_idfield, ensuring that the P2P functionality is tested with the new event structure.To improve the test:
- Consider using a parameterized value for
src_chain_idas suggested earlier.- It might be beneficial to test P2P forwarding with different
src_chain_idvalues to ensure proper handling of events from multiple chains.You could enhance the test by creating events with different
src_chain_idvalues:let evt_1 = EnclaveEvent::from(PlaintextAggregated { e3_id: E3id::new("1235"), decrypted_output: vec![1, 2, 3, 4], src_chain_id: 1, }); let evt_2 = EnclaveEvent::from(PlaintextAggregated { e3_id: E3id::new("1236"), decrypted_output: vec![1, 2, 3, 4], src_chain_id: 2, });This would help verify that the P2P actor correctly handles and forwards events from different chains.
Also applies to: 290-290
339-339: LGTM:src_chain_idadded toE3Requestedevent in P2P to bus forwarding test.The
E3Requestedevent used in the P2P to bus forwarding test has been correctly updated to include thesrc_chain_idfield, ensuring that this functionality is tested with the new event structure.To improve the test coverage:
- Consider using a parameterized value for
src_chain_idas suggested earlier.- It would be beneficial to test forwarding of events with different
src_chain_idvalues to ensure proper handling of events from multiple chains.- Consider adding assertions to verify that the
src_chain_idis correctly preserved when the event is forwarded to the bus.You could enhance the test by creating multiple events with different
src_chain_idvalues and verifying their forwarding:let chain_ids = vec![1, 2, 3]; for chain_id in chain_ids { let event = EnclaveEvent::from(E3Requested { e3_id: E3id::new(format!("1235_{}", chain_id)), threshold_m: 3, seed: seed.clone(), params: vec![1, 2, 3, 4], src_chain_id: chain_id, }); let _ = input.send(event.to_bytes()?).await; sleep(Duration::from_millis(1)).await; let history = bus.send(GetHistory).await?; assert_eq!(history.last().unwrap(), &event, "Event with src_chain_id {} was not correctly forwarded", chain_id); }This approach would verify that events from multiple chains are correctly forwarded and preserved.
Line range hint
1-353: Overall assessment: Changes align with PR objectives, but test improvements recommended.The modifications to this test file consistently implement the
src_chain_idfield across various events, aligning well with the PR objectives of supporting multiple chains and enhancing event handling. The tests cover crucial aspects of the system, including public key aggregation, decryption, and P2P event forwarding.Recommendations for improvement:
- Parameterize the
src_chain_idvalue to make tests more flexible and maintainable.- Extend test coverage to include scenarios with multiple chain IDs, ensuring robust handling of multi-chain events.
- Add specific assertions to verify the correct preservation and handling of
src_chain_idin forwarded events.These enhancements would significantly strengthen the test suite, providing greater confidence in the system's ability to handle multi-chain scenarios correctly.
packages/ciphernode/sortition/src/distance.rs (1)
28-28: Add context to the error for better debuggingWhen parsing the hexadecimal string, adding context to the error can aid in debugging if the conversion fails. Consider mapping the error to include more detailed information.
You can modify the code as follows to add context:
let z = BigInt::from_str_radix(without_prefix, 16) .map_err(|e| anyhow!("Failed to parse BigInt from hex '{}': {}", without_prefix, e))?;packages/ciphernode/enclave_node/src/ciphernode.rs (1)
68-68: Confirm default behavior for enabled chainsUsing
unwrap_or(true)means that chains without an explicitenabledflag are treated as enabled by default. Ensure this aligns with the intended configuration behavior. If the default should be to disable chains whenenabledis unspecified, consider usingunwrap_or(false)instead.packages/ciphernode/enclave_node/src/aggregator.rs (1)
55-55: Security Consideration: Hardcoded Environment VariableUsing a hardcoded environment variable name
"PRIVATE_KEY"may limit flexibility and could pose a security risk if not managed correctly.Consider parameterizing the environment variable name, perhaps by adding it to the
AppConfigorChainConfig. This allows for better configuration management and aligns with best practices for handling sensitive information.packages/ciphernode/core/src/eventbus.rs (1)
119-122: Add documentation comments to public trait and methodTo enhance code maintainability and readability, please add documentation comments to the
BusErrortrait and itserrmethod.Apply this diff to include the documentation:
+/// Trait to send errors directly to the event bus. pub trait BusError { + /// Sends an error event to the event bus. fn err(&self, err_type: EnclaveErrorType, err: anyhow::Error); }packages/ciphernode/evm/src/enclave_sol_writer.rs (2)
86-90: Avoid unnecessary cloning of variablesIn the
handlemethod forPlaintextAggregated(lines 86-90), several variables are cloned:let e3_id = msg.e3_id.clone(); let decrypted_output = msg.decrypted_output.clone(); let contract_address = self.contract_address.clone(); let provider = self.provider.clone(); let bus = self.bus.clone();Cloning can be expensive, especially for large data structures. If possible, consider borrowing references or moving ownership if the variables are not needed elsewhere.
Possible refactoring:
- let e3_id = msg.e3_id.clone(); - let decrypted_output = msg.decrypted_output.clone(); - let contract_address = self.contract_address.clone(); - let provider = self.provider.clone(); - let bus = self.bus.clone(); + let e3_id = msg.e3_id; + let decrypted_output = msg.decrypted_output; + let contract_address = self.contract_address; + let provider = self.provider.clone(); // Clone if needed elsewhere + let bus = self.bus.clone(); // Clone if needed elsewhereEnsure that this change does not affect other parts of the code where these variables are used.
25-30: Document all fields in theEnclaveSolWriterstructWhile there is a brief module-level comment, the fields within the
EnclaveSolWriterstruct (lines 25-30) lack individual documentation.Providing documentation comments for each field improves code readability and aids future maintenance.
Example:
pub struct EnclaveSolWriter { + /// Provider with signer capabilities to interact with the blockchain provider: SignerProvider, + /// Address of the Enclave smart contract contract_address: Address, + /// Event bus for handling enclave events bus: Addr<EventBus>, }packages/ciphernode/evm/src/enclave_sol_reader.rs (3)
105-110: Derive traits forEnclaveSolReaderas neededThe
EnclaveSolReaderstruct may benefit from deriving standard traits likeDebugto aid in logging and debugging. Ensure that necessary traits are derived to facilitate these activities.Consider adding
#[derive(Debug)]:+#[derive(Debug)] pub struct EnclaveSolReader { provider: ReadonlyProvider, contract_address: Address, bus: Recipient<EnclaveEvent>, }
147-147: Consider starting from a configurable block numberCurrently, the filter uses
BlockNumberOrTag::Latestto start listening for events from the latest block. Depending on the application requirements, it might be necessary to start from a specific block number (e.g., the block when the contract was deployed) to capture all relevant events.Consider making the starting block number configurable:
let filter = Filter::new() .address(self.contract_address) - .from_block(BlockNumberOrTag::Latest); + .from_block(starting_block_number);You can pass
starting_block_numberas a parameter or fetch it from the configuration.
44-44: Add documentation forE3RequestedWithChainIdstructThe
E3RequestedWithChainIdstruct combines anE3Requestedevent with achain_id, but it lacks documentation. Adding a doc comment will improve code readability and maintainability.Add a doc comment:
+/// A wrapper struct combining `E3Requested` event data with the `chain_id`. struct E3RequestedWithChainId(pub E3Requested, pub u64);packages/ciphernode/core/src/ordered_set.rs (1)
213-229: Adjust test to avoid relying on element orderThe
OrderedSetuses aBTreeSet, which orders elements based on their natural ordering. While your test passes because the elements are sorted lexicographically, relying on this order might lead to brittle tests if the ordering criteria change.Consider verifying the set contents without assuming order:
assert_eq!(set.len(), 3); assert!(set.contains(&"apple".to_string())); assert!(set.contains(&"banana".to_string())); assert!(set.contains(&"cherry".to_string())); let expected: BTreeSet<&String> = ["apple", "banana", "cherry"].iter().map(|s| s).collect(); let actual: BTreeSet<&String> = set.iter().collect(); assert_eq!(actual, expected);packages/ciphernode/aggregator/src/publickey_aggregator.rs (1)
33-37: Add documentation for the newNotifyNetworkmessageThe
NotifyNetworkstruct has been introduced to handle network notifications. To maintain code clarity and assist other developers, consider adding Rust doc comments explaining the purpose and usage of this message.Apply this diff to add documentation:
#[derive(Message)] #[rtype(result = "anyhow::Result<()>")] struct NotifyNetwork { + /// The aggregated public key to be notified to the network pub pubkey: Vec<u8>, + /// The identifier for the E3 protocol instance pub e3_id: E3id, }packages/ciphernode/core/src/events.rs (2)
48-53: Consider enhancing error handling inTryFrom<E3id> for U256implementation.The implementation correctly attempts to convert
E3idtoU256usingfrom_str_radix. However, adding context to theParseErroror logging the error may improve debugging in case of conversion failures.
323-327: Address the TODO comments or remove if obsolete.The
E3Requestedstruct contains several TODO comments for fields likethreshold,computation_type,execution_model_type,input_deadline, andavailability_duration. Consider implementing these fields if they are required for future functionality, or remove the comments to keep the codebase clean.Would you like assistance in defining and implementing these fields?

25-25: LGTM: Addition ofpreciphernode:buildscript improves build process.The new
preciphernode:buildscript is a great addition that ensures the EVM is compiled before building theciphernode. This aligns well with the PR objectives by improving the build process and handling dependencies correctly.Consider adding a comment in the
package.jsonfile to explain the purpose of this script, especially its relationship withciphernode:build. This would improve maintainability for future developers.

28-58: LGTM: RegistryFilterSolWriter implementation with a minor suggestion.The implementation of RegistryFilterSolWriter is well-structured with appropriate new and attach methods. The new method correctly initializes the struct, and the attach method properly sets up the actor and event subscription.
Consider adding error handling for the bus.send() call in the attach method:
- let _ = bus - .send(Subscribe::new("PublicKeyAggregated", addr.clone().into())) - .await; + bus.send(Subscribe::new("PublicKeyAggregated", addr.clone().into())) + .await + .map_err(|e| anyhow::anyhow!("Failed to subscribe to PublicKeyAggregated event: {}", e))?;This change ensures that any subscription errors are properly propagated and handled.
64-77: LGTM: Handler implementation with a suggestion for improved logging.The implementation correctly handles PublicKeyAggregated events and checks for matching chain IDs. This ensures that only relevant events are processed.
As suggested in a previous review, consider adding a warning log when chain IDs don't match:
if self.provider.get_chain_id() == data.src_chain_id { ctx.notify(data); +} else { + log::warn!( + "Received PublicKeyAggregated event with mismatched chain IDs: provider_chain_id={}, data_src_chain_id={}", + self.provider.get_chain_id(), + data.src_chain_id + ); }This will improve visibility into potential issues with mismatched chain IDs.

146-152: Consider Consolidating or RenamingattachMethods for ClarityThe
CiphernodeRegistrySolReaderandCiphernodeRegistrySolstructs both have anattachmethod. This could lead to confusion and potential misuse.Suggestion: Unify or Clearly Differentiate the
attachMethods
If both methods serve the same purpose, consider removing one to avoid redundancy.
Alternatively, rename one of the methods to more accurately reflect its role. For example:
pub struct CiphernodeRegistrySol; impl CiphernodeRegistrySol { - pub async fn attach(bus: Addr<EventBus>, rpc_url: &str, contract_address: &str) -> Result<()> { + pub async fn register(bus: Addr<EventBus>, rpc_url: &str, contract_address: &str) -> Result<()> { CiphernodeRegistrySolReader::attach(bus.clone(), rpc_url, contract_address).await?; Ok(()) } }This improves code readability and helps prevent confusion between methods.

packages/ciphernode/evm/src/enclave_sol_writer.rs (9)
1-21: LGTM: Well-structured imports and contract interface definitionThe imports are comprehensive and logically organized. The use of the
sol!macro to define theIEnclavecontract interface is a good practice for working with Ethereum contracts in Rust.
23-42: LGTM: Well-designed struct and constructorThe
EnclaveSolWriterstruct and itsnewmethod are well-designed. The use ofResultfor error handling in the constructor is a good practice, allowing for proper error propagation.
61-78: LGTM: Proper implementation of Actor and Handler traitsThe implementation of the
Actortrait and theHandler<EnclaveEvent>forEnclaveSolWriteris well-done. The chain ID check in thehandlemethod aligns with the multichain objectives mentioned in the PR summary, ensuring that operations match on chain_id when writing to the chain.
96-97: Use a logging framework instead ofprintln!As mentioned in the previous comment, it's recommended to use a logging framework instead of
println!for better control over logging levels and outputs. Consider using thelogcrate:- println!("tx:{}", receipt.transaction_hash) + log::info!("Transaction hash: {}", receipt.transaction_hash);Ensure that the logging framework is properly initialized in your application.
98-99: LGTM: Proper error handling using the event busThe error handling approach aligns with the PR objective of sending unrecovered errors to the bus for logging or recovery. This is a good practice for centralized error management in a distributed system.
105-118: LGTM: Well-implementedpublish_plaintext_outputfunctionThe
publish_plaintext_outputfunction is well-implemented. It correctly prepares the transaction data and sends it to the Enclave contract. The use ofResultfor error handling is a good practice, allowing for proper error propagation.
53-55:⚠️ Potential issueImplement error handling for event bus subscription
The previous comment about handling potential errors during event bus subscription has not been addressed. It's important to handle any errors that may occur during the subscription to ensure robustness.
Consider modifying the code to handle errors appropriately:
- let _ = bus - .send(Subscribe::new("PlaintextAggregated", addr.clone().into())) - .await; + bus + .send(Subscribe::new("PlaintextAggregated", addr.clone().into())) + .await + .map_err(|e| anyhow::anyhow!("Failed to subscribe to PlaintextAggregated event: {}", e))?;This change will propagate any subscription errors, allowing for proper error handling and logging.
113-113:⚠️ Potential issueReplace hardcoded proof with actual proof data
The previous comment about replacing the hardcoded proof with actual proof data has not been addressed. Using a placeholder value for the proof may not be appropriate for production code.
Consider implementing a function to generate or fetch the actual proof:
- let proof = Bytes::from(vec![1]); + // TODO: Generate or fetch the actual proof required by the contract + let proof = generate_actual_proof(e3_id, decrypted_output).await?;Implement the
generate_actual_prooffunction to provide the correct proof data required by the smart contract.
1-118: Overall implementation meets PR objectives with minor improvements neededThe
EnclaveSolWriterimplementation successfully addresses the PR objectives of simplifying the evm package, allowing for direct sending of unrecovered errors to the bus, and introducing internal handling of the chain_id. The code structure and error handling practices are generally good.However, there are a few minor issues that should be addressed to improve code quality and robustness:
- Implement error handling for the event bus subscription in the
attachmethod.- Replace
println!with a proper logging framework.- Replace the hardcoded proof with actual proof data in the
publish_plaintext_outputfunction.Addressing these issues will further enhance the reliability and maintainability of the code.
To ensure that the logging framework is properly initialized and used throughout the codebase, run the following script:
packages/ciphernode/evm/src/registry_filter_sol.rs (4)
1-20: LGTM: Imports and smart contract interface definition.The imports cover all necessary modules and types for the implementation. The smart contract interface for NaiveRegistryFilter is correctly defined using the sol! macro, referencing the appropriate JSON artifact.
22-27: LGTM: RegistryFilterSolWriter struct definition.The RegistryFilterSolWriter struct is well-defined with appropriate fields for interacting with the smart contract and event bus. The use of SignerProvider, Address, and Addr types is correct for their intended purposes.
60-62: LGTM: Actor implementation for RegistryFilterSolWriter.The Actor trait is correctly implemented for RegistryFilterSolWriter, setting the appropriate Context type. This implementation is necessary for the struct to function as an actor in the Actix system.
1-134: Overall assessment: Well-structured implementation with room for improvements.The RegistryFilterSol functionality is generally well-implemented, with appropriate use of Actix actors, smart contract interactions, and event handling. However, several improvements can be made to enhance the code's robustness, maintainability, and adherence to best practices:
- Implement proper error handling for the event subscription in the
attachmethod.- Add warning logs for mismatched chain IDs in the
Handler<EnclaveEvent>implementation.- Replace
println!with structured logging in theHandler<PublicKeyAggregated>implementation.- Enhance error handling with more context in the
Handler<PublicKeyAggregated>implementation.- Handle parsing errors explicitly when processing node addresses in the
publish_committeefunction.- Consider removing the redundant
RegistryFilterSolstruct and itsattachmethod.Implementing these suggestions will significantly improve the overall quality and maintainability of the code.
packages/ciphernode/evm/src/enclave_sol_reader.rs (8)
1-15: Imports and contract bindings look good.The imports cover all necessary modules and types for interacting with Ethereum and handling events. The
sol!macro usage for generating Rust bindings from the IEnclave contract JSON ABI is correct and follows the project's conventions.
17-36: New struct and implementations align with multichain support objective.The introduction of
E3RequestedWithChainIdand its implementations for conversion toenclave_core::E3RequestedandEnclaveEventsuccessfully incorporate thesrc_chain_idfield. This change aligns well with the PR objective of supporting multiple chains and ensures that the chain ID is properly propagated through the event system.
79-97: EnclaveSolReader struct looks good, but improve error handling in the new method.The EnclaveSolReader struct and its new method align well with the PR objective of simplifying the evm package. However, the error handling in the new method could be improved to provide more context, especially for input parameter validation.
Consider applying this diff to improve error handling:
- let provider = create_readonly_provider(rpc_url).await?; + let provider = create_readonly_provider(rpc_url).await.map_err(|e| { + anyhow::anyhow!("Failed to create provider for RPC URL '{}': {}", rpc_url, e) + })?;This change will provide more context in case of an error, making it easier to diagnose issues during initialization.
1-127: Summary: EnclaveSolReader implementation aligns well with PR objectivesThe
enclave_sol_reader.rsfile successfully implements multichain support and simplifies the evm package, addressing the objectives outlined in the PR and linked issues. Key achievements include:
- Introduction of the
E3RequestedWithChainIdstruct to support multiple chains.- Simplified and modular structure of the
EnclaveSolReaderactor.- Implementation of event extraction and conversion logic.
To further improve the code, consider implementing the suggested enhancements to error handling and logging throughout the file. These improvements will significantly increase the robustness, maintainability, and debuggability of the system.
Overall, this implementation is a solid step towards achieving the project's multichain capabilities and improving its architecture.
54-76:⚠️ Potential issueImprove error handling and logging in the extractor function.
The extractor function's logic for decoding log data and converting it to EnclaveEvent is correct. However, there are some improvements needed:
- Replace
println!statements with proper logging using a library likelogortracing. This aligns with a previous review comment and is more suitable for production code.- Provide more detailed error information as indicated by the TODO comments.
- Consider using
log::warn!for unknown events instead ofprintln!.Apply this diff to improve error handling and logging:
- println!("Error parsing event E3Requested"); // TODO: provide more info + log::error!("Error parsing E3Requested event: {:?}", data); - println!("Error parsing event CiphertextOutputPublished"); // TODO: provide more info + log::error!("Error parsing CiphertextOutputPublished event: {:?}", data); - println!("Unknown event"); + log::warn!("Unknown event with topic: {:?}", topic);
99-111:⚠️ Potential issueImprove logging and error handling in the attach method.
The attach method successfully creates and starts a new EnclaveSolReader instance. However, there are some improvements needed:
- Replace
println!with proper logging using a library likelogortracing. This aligns with a previous review comment and is more suitable for production code.- Improve error handling to provide more context, similar to the suggestion for the new method.
Apply these changes to improve logging and error handling:
- let addr = EnclaveSolReader::new(bus.clone(), contract_address.parse()?, rpc_url) + let contract_addr = contract_address.parse().map_err(|e| { + anyhow::anyhow!("Failed to parse contract address '{}': {}", contract_address, e) + })?; + let addr = EnclaveSolReader::new(bus.clone(), contract_addr, rpc_url) .await? .start(); - println!("Evm is listening to {}", contract_address); + log::info!("EVM is listening to contract address: {}", contract_address);These changes will provide better error context and use proper logging, improving the overall robustness of the code.
113-127:⚠️ Potential issueImprove error handling in the spawned future within the started method.
The Actor implementation for EnclaveSolReader correctly sets up a stream to listen for events from the Ethereum network. However, the error handling in the spawned future could be improved to prevent silent failures.
Consider modifying the code to handle errors explicitly:
ctx.spawn( - async move { helpers::stream_from_evm(provider, filter, bus, extractor).await } + async move { + if let Err(e) = helpers::stream_from_evm(provider, filter, bus, extractor).await { + log::error!("Error in stream_from_evm: {}", e); + // Consider implementing a retry mechanism or notifying a supervisor + } + } .into_actor(self), );This change ensures that any errors occurring in the
stream_from_evmfunction are logged and not silently ignored, improving the reliability and debuggability of the system.
38-52: CiphertextOutputPublished event handling looks correct, but verify chain ID requirement.The implementations for converting
IEnclave::CiphertextOutputPublishedtoenclave_core::CiphertextOutputPublishedandEnclaveEventare logically correct. However, unlike the E3RequestedWithChainId struct, there's no chain ID included in these conversions.Could you confirm if the chain ID is not required for CiphertextOutputPublished events? If it is needed, we should update these implementations to include it.
packages/ciphernode/evm/src/ciphernode_registry_sol.rs (3)
1-13: Imports and Module Setup Are CorrectThe necessary crates and modules are imported, and the code is well-organized. The use of the
solmacro is appropriate for interfacing with Solidity contracts.
20-65: Trait Implementations for Event Conversion Are CorrectThe
Fromtrait implementations for converting Solidity events to Rust structures are correctly defined, facilitating seamless data transformation between the EVM and the enclave.
93-113: Struct Initialization andnewMethod Are Properly DefinedThe
CiphernodeRegistrySolReaderstruct and itsnewmethod correctly initialize the provider, contract address, and event bus. The use of asynchronous initialization with proper error handling is appropriate.
