63-63: Consider using only the necessarytokiofeatures.The addition of
tokioas a development dependency is reasonable for testing asynchronous code. However, the "full" feature set might not be necessary and could increase compile times.Please verify if all the features in the "full" feature set are being used. If not, consider specifying only the necessary features to reduce compile times. You can refer to the
tokiodocumentation for the list of available features: https://docs.rs/tokio/latest/tokio/#feature-flags

8-8: LGTM!The addition of the
sr25519module is a valid way to extend the functionality of the library to support the SR25519 signature scheme. The module name is clear and follows the naming convention of the other modules in the library.packages/kos-sdk/src/chains/mod.rs (2)
6-6: LGTM!The declaration of the
polkadotmodule aligns with the existing pattern and the PR objective. The naming is clear and follows the convention used for other blockchain modules.
14-14: LGTM!The re-export of the
DOTsymbol from thepolkadotmodule aligns with the existing pattern and the PR objective. The symbol name follows the convention used for other blockchain symbols and matches the common abbreviation for Polkadot.packages/kos-sdk/Cargo.toml (2)
35-38: LGTM!The formatting changes to the
web3dependency improve readability without affecting functionality.
43-47: LGTM!The formatting changes to the
reqwestdependency improve readability without affecting functionality.packages/kos-sdk/src/chains/polkadot/address.rs (1)
1-69: LGTM!The
Addressstruct and its associated methods are well-implemented and provide the necessary functionality for handling Polkadot addresses. The code follows best practices and includes appropriate error handling.Some key points:
- The struct is defined with a fixed-size array of 32 bytes, ensuring the correct address length.
- The
from_publicandfrom_keypairmethods allow creating an address from a public key or a keypair, respectively.- The
as_bytes,from_bytes, andto_hex_addressmethods provide convenient ways to convert between different representations of the address.- The
FromStrandDisplaytrait implementations enable parsing and formatting the address in the SS58 format, which is commonly used in Substrate-based chains.- The use of
wasm_bindgenattribute allows the struct to be exposed to JavaScript, enhancing interoperability.Overall, the code is well-structured, follows best practices, and provides a solid foundation for working with Polkadot addresses in the SDK.
packages/kos-crypto/src/sr25519.rs (5)
11-13: LGTM!The
Sr25519KeyPairstruct is correctly defined with a privatekeypairfield to encapsulate the internal state. The struct is also annotated with#[wasm_bindgen]to enable interoperability with JavaScript.
41-80: LGTM!The
Sr25519KeyPairstruct implements essential methods for generating key pairs from random seeds, mnemonic phrases, and derivation paths. The methods are correctly implemented and provide the necessary functionality.
83-86: LGTM!The
public_keymethod is correctly implemented and returns the public key associated with the key pair as a byte vector.
89-92: LGTM!The
sign_digestmethod is correctly implemented and signs the provided message using the key pair. The signature is obtained and returned as a byte vector.
94-101: LGTM!The
verify_digestmethod is correctly implemented and verifies the provided signature against the message and public key. The method converts the public key and signature to their respective types and calls theverifymethod from thesr25519::Pairmodule to perform the verification.packages/kos-crypto/src/keypair.rs (6)
3-3: LGTM!The import of the
sr25519module is necessary to support the newSr25519key type.
15-15: LGTM!The addition of the
Sr25519variant to theKeyTypeenum is necessary to support the new key type in theKeyPairstruct.
24-24: LGTM!The addition of the
sr25519field to theKeyPairstruct is necessary to store theSr25519key pair.
60-66: LGTM!The addition of the
new_sr25519method to theKeyPairstruct is necessary to create aKeyPairinstance specifically forSr25519keys.
79-79: LGTM!The updates to the
sign_digestandverify_digestmethods to handle theSr25519key type are necessary to ensure that the appropriate signing and verification processes are invoked forSr25519key pairs.Also applies to: 101-106
131-131: LGTM!The update to the
public_keymethod to handle theSr25519key type is necessary to ensure that the public key is correctly retrieved forSr25519key pairs.packages/kos-sdk/src/chain.rs (1)
138-138: Approve addition of DOT chain with a note on assumptions.The addition of the
DOTchain identifier to thecreateChains!macro invocation is a valid change that will generate the necessary code for supporting the DOT chain within theChainenum and its associated methods.However, it's important to note that this change assumes the existence of a
DOTmodule that implements the required methods and types, following the pattern of the other chain identifiers. The provided code does not show the implementation of theDOTmodule.To verify the existence and correctness of the
DOTmodule, you can run the following script:This script checks for the existence of the
DOTmodule file and verifies that it implements the required methods. If any of the checks fail, the script will output an error message and exit with a non-zero status code.Please ensure that the
DOTmodule is implemented correctly to support the integration of the DOT chain into theChainenum and its associated functionality.Verification successful
This script will help us verify if there are any DOT-related files in the project and check the structure of other chain module files. This information will allow us to determine if the DOT implementation is truly missing or if it's located in an unexpected place.
This script will help us inspect the contents of the 'polkadot' subdirectory, check for Rust files, and verify the presence of required methods if any Rust files are found. This information will allow us to determine if the DOT implementation exists and is complete.
DOT implementation verified and complete
The DOT (Polkadot) chain implementation has been successfully verified. All required methods are present in the Rust files (
address.rsandmod.rs) within thepackages/kos-sdk/src/chains/polkadot/directory. The implementation follows the project's structure for chain implementations and includes all necessary functionality.The addition of DOT to the
createChains!macro is fully supported by the existing implementation, ensuring proper integration with the rest of the codebase.Scripts executed

64-64: Consider optimizing tokio features for developmentWhile the change is acceptable, consider specifying only the required tokio features instead of using "full" to potentially improve compilation times during development.
-tokio = { version = "1", features = ["full"] } +tokio = { version = "1", features = ["rt-multi-thread", "macros"] }packages/kos-sdk/src/chain.rs (2)
158-158: Document chain codes for new additions.While the placement of DOT, KSM, and AVAIL preserves existing chain codes, it would be helpful to document their assigned codes explicitly. Consider adding comments or constants to make the chain codes clear and maintainable.
-createChains!(NONE, KLV, TRX, BTC, ETH, MATIC, DOT, KSM, AVAIL); +// Chain codes: +const NONE_CODE: u8 = 0; +const KLV_CODE: u8 = 1; +// ... existing chains ... +const DOT_CODE: u8 = 6; +const KSM_CODE: u8 = 7; +const AVAIL_CODE: u8 = 8; + +createChains!(NONE, KLV, TRX, BTC, ETH, MATIC, DOT, KSM, AVAIL);
Line range hint
160-213:⚠️ Chain code mismatch with historical values.The commented enum shows different historical chain codes:
- DOT was previously code 21
- KSM was previously code 27
- AVAIL is not listed
The current implementation assigns different codes to these chains, which could break compatibility with existing systems or stored data.
Please verify if this change is intentional and ensure it won't impact existing systems. Consider:
- Using the historical chain codes
- Documenting the reason for the change
- Adding migration steps if needed
packages/kos-sdk/src/models.rs (1)
73-73: Consider completing Substrate implementation before merging.The current changes introduce Substrate chain support but leave critical parts unimplemented:
- The
get_rawimplementation for Substrate transactions is missing- The transaction parsing methods use inconsistent naming
- There's no clear documentation about the differences between JSON and raw transaction formats
Consider:
- Completing the Substrate transaction implementation
- Adding documentation about the transaction format differences
- Adding tests to verify the new chain implementations

52-67: Enhance error handling in theFromStrimplementationReturning
&'static stras an error type provides limited context. Consider using a custom error type orStringfor more informative error messages.Apply this diff to improve error reporting:
impl FromStr for Address { - type Err = &'static str; + type Err = String; fn from_str(s: &str) -> Result<Self, Self::Err> { let decoded = Public::from_ss58check_with_version(s) - .map_err(|_| "Invalid address")?; + .map_err(|e| format!("Invalid address: {:?}", e))?; if decoded.0.len() != ADDRESS_LEN { - return Err("Invalid address length"); + return Err(format!( + "Invalid address length: expected {}, got {}", + ADDRESS_LEN, decoded.0.len() + )); } let mut raw = [0u8; ADDRESS_LEN]; raw.copy_from_slice(&decoded.0); Ok(Address(raw)) } }This provides clearer error messages, aiding in debugging and user feedback.

166-177: Enhance Test Coverage for Keypair GenerationThe
test_keypair_from_mnemonicfunction uses a fixed mnemonic and path. To ensure robustness, consider adding tests with varying mnemonics, derivation paths, and passwords.Expanding test cases will help in catching edge cases and potential bugs related to keypair generation.
#[test] fn test_keypair_from_mnemonic_with_different_paths() { let mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"; let paths = vec!["//0", "//1", "//hard/0", "//soft/0"]; for path in paths { let kp = AVAIL::keypair_from_mnemonic(mnemonic, path, None).unwrap(); let address = AVAIL::get_address_from_keypair(&kp).unwrap(); assert!(!address.is_empty()); } }
199-207: Use a Random Keypair intest_sign_digestIn the
test_sign_digestfunction, the keypair is generated from a private key consisting of 32 zeros. While acceptable for testing purposes, using a randomly generated keypair better simulates real-world scenarios.Modify the keypair generation to use the
randommethod:fn test_sign_digest() { - let kp = AVAIL::keypair_from_bytes(&[0u8; 32]).unwrap(); + let kp = AVAIL::random().unwrap(); let digest = b"hello".to_vec(); let signature = AVAIL::sign_digest(&digest, &kp).unwrap(); assert_eq!(signature.len(), 64);packages/kos-sdk/src/chains/kusama/mod.rs (1)
148-158: Add Documentation fortx_from_jsonMethodThe
tx_from_jsonfunction lacks documentation. Adding a doc comment will improve code readability and help other developers understand its purpose and usage.Suggestion:
/// Constructs a `Transaction` object from a JSON string specific to Kusama. /// /// # Arguments /// /// * `raw` - A JSON string representing the transaction data. /// /// # Returns /// /// A `Result` containing the `Transaction` object or an `Error`. pub fn tx_from_json(raw: &str) -> Result<Transaction, Error> { // existing implementation }

Based on the verification results, I can now provide a final response:
All required chain functions are properly implemented
The verification shows that:
- All three chains (DOT, KSM, AVAIL) are properly registered in the
createChains!macro- All required functions are implemented for each chain:
- KSM and AVAIL reuse DOT's implementations where appropriate
- Each chain has its own SS58_PREFIX for address generation
- Core cryptographic operations are properly delegated to the base implementation
- The implementations include proper error handling and type safety

7-7: LGTM: Import changes align with new chain support.The addition of AVAIL, DOT, and KSM imports is consistent with the PR's objective of adding Polkadot ecosystem support.
216-218: Verify chain-specific transaction parsing methods.The implementation uses different method names (
tx_from_json) compared to other chains (tx_from_raw). Let's verify:
- The methods exist in their respective modules
- The naming difference is intentional
Consider aligning method names across all chains for consistency:
- Either rename all to
tx_from_raw- Or rename all to
tx_from_json- Or document why different methods are needed
✅ Verification successful
Let me gather more information about the
tx_from_rawmethods to understand the full context.
Method naming differences are intentional and correct
The verification reveals that the method naming differences are intentional and reflect different transaction encoding formats across chains:
tx_from_jsonis used by Substrate-based chains (DOT, KSM, AVAIL) which share common transaction parsing logic viaSubstrateTransaction::from_jsontx_from_rawis used by chains with binary/hex formats:
- TRON: Uses protobuf encoding
- Klever: Uses protobuf encoding
- Ethereum: Uses RLP encoding
The different method names actually improve clarity by indicating the expected input format for each chain family.

Let me gather more information about the implementation details of the Substrate transaction type.
Let me try one more search to locate the transaction implementation:
SubstrateTransaction implementation is properly defined and used
The SubstrateTransaction (aliased from polkadot::transaction::Transaction) is well-implemented with:
- Complete struct definition with all necessary fields for Substrate-based transactions
- Proper serialization/deserialization support via serde
- Implementation of
from_jsonfor parsing transaction data- Comprehensive ExtrinsicPayload handling for transaction signing
The type is correctly used across DOT, KSM, and AVAIL chains, maintaining consistency in the codebase.

68-75:⚠️ Potential issueVerify the key derivation method to ensure compliance with standard practices
The current implementation concatenates the mnemonic phrase with the path to derive the seed:
let seed = format!("{}{}", m.to_phrase(), path);This approach may not align with standard sr25519 key derivation practices and could lead to security vulnerabilities. Consider using established methods or libraries for key derivation, such as
sp_core::Pair::from_phraseor implementing the standard BIP32/BIP44 derivation.Would you like assistance in updating the key derivation method to follow standard practices?

AVAIL::get_address_from_keypairand updating the test accordingly.
148-158: Review AVAIL Transaction Construction intx_from_jsonThe

While this may be efficient, it's crucial to ensure that AVAIL's cryptographic and address derivation mechanisms are fully compatible with Polkadot's (DOT). Any discrepancies could lead to incorrect behavior or security vulnerabilities.To confirm compatibility, please verify that AVAIL and DOT share the same key derivation paths, address formats, and cryptographic algorithms.

198-205: Confirm Correctness of Signature Length and VerificationIn
test_sign_digest, the length of the signature is asserted to be 64 bytes. While SR25519 signatures are typically 64 bytes, it's good to confirm that this aligns with the expected behavior for Kusama.Action:
- Double-check that the signature length of 64 bytes is correct for SR25519 on Kusama.
- Ensure that the verification step is reliable and handles edge cases.
142-146: Validate Address Verification Logic for KusamaThe
validate_addressmethod delegates toDOT::validate_address. Since Kusama and Polkadot addresses may have different prefixes or validation rules, ensure that the validation logic is appropriate for Kusama addresses.Action:
- Review the validation logic in
DOT::validate_addressto confirm it accounts for Kusama's SS58 prefix and address format.- Adjust the validation logic if necessary to accurately validate Kusama addresses.
Verification Script:

- Confirm that
2is the correct SS58 prefix for Kusama by checking the official documentation or reliable sources.Verification Script:
✅ Verification successful
SS58 Prefix for Kusama is Correctly Set to 2
The verification is successful based on several pieces of evidence from the codebase:
- The SS58 prefix is correctly set to 2 for Kusama in
packages/kos-sdk/src/chains/kusama/mod.rs- The test case in the same file successfully validates address generation using this prefix, specifically verifying that the address "Etp93jqLeBY8TczVXDJQoWNvMoY8VBSXoYNBYou5ghUBeC1" is generated correctly from a known mnemonic

✅ Verification successful
No Issues with DOT::get_balance Usage in KSM Implementation
The implementation is correct. Looking at the codebase:
- The
DOT::get_balanceimplementation inpolkadot/mod.rsis a generic Substrate-based balance retrieval method.- Both Kusama and Polkadot are Substrate-based chains that share the same underlying architecture and balance retrieval mechanism.
- The only difference is the node URL, which is correctly handled by passing the KSM-specific node URL:
crate::utils::get_node_url("KSM").This pattern is also used by other Substrate-based chains in the codebase (e.g., AVAIL), indicating it's an intentional design choice to reuse the common Substrate balance retrieval logic.

Avoid using transmute to eliminate unsafe code
The use of std::mem::transmute is unsafe and can lead to undefined behavior. Consider a safer alternative to convert bytes into an Address.
Apply this diff to safely construct Address from bytes:
- pub fn from_bytes(raw: &[u8]) -> &Address {

Implement the send Method
The send method currently contains a todo!() macro, indicating it's not yet implemented. This method is essential for enabling transactions on the Kusama network.
Recommendation:
- Implement the
sendmethod to allow users to send transactions. - Ensure it correctly handles Kusama-specific transaction construction and submission.
Offer:
Do you need assistance in drafting the implementation for the send method? I can help create a skeleton or full implementation based on Kusama's transaction requirements.

Enhance Test Coverage and Robustness
The test suite covers basic functionality but can be improved to ensure code robustness.
Recommendations:
-
Add Edge Case Tests:
- Test with invalid mnemonics in
test_keypair_from_mnemonic. - Validate behavior when providing incorrect paths.
- Test with invalid mnemonics in
-
Assert Error Handling:
- In
test_validate_address, include tests for invalid addresses and assert that the method returnsfalseor an appropriate error.
- In
-
Consistency in Test Data:
- Ensure that test data used across different tests are consistent or clearly defined to avoid confusion.
Example:
#[test]
fn test_validate_invalid_address() {
let invalid_address = "InvalidKusamaAddress123";
let valid = KSM::validate_address(invalid_address, None).unwrap_or(false);
assert_eq!(valid, false);
}Implementing these suggestions will strengthen the test suite and help catch potential issues early in development.
