packages/libcheese/src/solana.rs (7)
141-153: Distinguish 'account not found' errors from other RPC errors
In theErr(_)branch, the code immediately attempts to create the token account, but the failure cause might be something other than a missing account (e.g., network issue).
Refining this error handling or logging can prevent unintended account creation.
155-160: Robust parse handling
Using.parse::<u64>().unwrap_or(0)might silently mask parsing errors if the RPC returns unexpected data.
Consider logging or handling parse failures more explicitly to avoid confusion.Also applies to: 162-168
213-224: Simulation error logging
Capturing and printing the simulation error plus logs is helpful for debugging.
For production usage, consider upgrading to a structured logging framework rather thanprintln!.
Line range hint
415-423: Basic trade execution logs
These logs provide good at-a-glance details for debugging.
Consider adopting consistent, structured logging across the project.
Line range hint
479-480: Percentage-based target token usage
Using a fixed 10% of target liquidity is a simplistic approach.
If you need more dynamic risk management, consider refining this strategy.
Line range hint
528-529: Partial target token usage
Again, 10% is a fixed figure that may not reflect all market conditions.
Consider making this adaptive if needed.
Line range hint
587-591: Static 10% vs 5% trade size
Choosing a constant fraction of liquidity, while simple, may not be optimal.
For sophisticated trading, consider more dynamic logic.packages/cli/src/main.rs (1)
122-122: Improved error handling withanyhow!
This change provides a more direct error context for keypair file reading.
For more robust error tracking, consider structured or contextual logs.

12-12: Use of spl_token import
No issues found. This import is necessary for the new token-related logic.
112-123: Blockhash verification and signing improvements
This logic ensures the transaction is refreshed with the latest blockhash and handles signing if the transaction is not already signed.
Consider verifying multi-sig requirements if other signers are needed in certain contexts.
175-199: Creating associated token account
Implementation closely follows recommended patterns for creating an associated token account.
This looks correct and maintains clarity.
230-247: Error reporting in send_and_confirm_transaction
Fetching the transaction status on failure is valuable for diagnosing issues.
This approach is acceptable; consider structured logs for improved maintainability.
249-263: Ensuring token account creation
Similar logic to check_token_balance: a generic Err(_) from get_account triggers creation.
Distinguishing “account not found” from other errors may improve correctness.
Line range hint 431-442: Ensuring token accounts exist before trading
Sequential sanity checks on token account existence reduce failures mid-trade.
No major issues noted.
Line range hint 445-450: Sell path initialization
Clear step-by-step user-facing logs.
Verify these path details match the intended trade flow in docs or comments.
Line range hint 464-465: CHEESE amount conversion
Multiplying by 1_000_000_000.0 assumes 9 decimals for CHEESE.
Confirm the token’s decimal precision to prevent under/overfunding.
Line range hint 493-494: Final step usage
This logs the initial amount of CHEESE again. If you accumulate more (or less) CHEESE after prior steps, ensure that’s reflected.
Line range hint 500-505: Buy path initialization
Similar approach to the sell path, with consistent logging.
No immediate issues noticed.
Line range hint 513-514: CHEESE amount conversion
As above, verify 9 decimal places are correct for CHEESE to avoid mismatch.
Line range hint 542-543: Final step: CHEESE -> USDC
Re-check that the final step’s amount in CHEESE accurately reflects any preceding trades.
Line range hint 575-575: Identifying USDC pool
Using pool_token_mints.contains(...) is clear and straightforward.
packages/cli/src/main.rs (2)
1-1: Use of anyhow::Result
Imports look good. This is a convenient and flexible error type.
3-3: Added USDC_MINT import
Consistent with the code in libcheese/src/common.rs, ensuring a unified reference to USDC.
packages/libcheese/Cargo.toml (1)
15-15: Added spl-token = "4.0.0"
Aligns with new token account functionalities in solana.rs.

142-169: Good improvements in token balance verificationThe changes improve reliability by:
- Checking token account existence
- Creating missing accounts automatically
- Using raw amounts for accurate comparison
Consider extracting the power of 10 calculation to a constant or helper method for better readability:
+ const fn get_token_decimals_multiplier(decimals: u8) -> f64 { + 10f64.powi(decimals as i32) + } - amount as f64 / 10f64.powi(balance.decimals as i32) + amount as f64 / get_token_decimals_multiplier(balance.decimals)
214-225: Good enhancement of transaction simulation feedbackThe improved error reporting helps with debugging. Consider formatting the logs for better readability:
- println!("Transaction logs:"); + println!("\nTransaction logs:"); for log in logs { - println!(" {}", log); + println!(" {}", log); }

💡 Codebase verification
Missing test coverage for new token account utility methods
The codebase has a test module in solana.rs, but it currently only has a placeholder for test_trade_executor. The newly added public methods ensure_token_account and get_token_balance lack test coverage. These methods handle critical token account operations and should be thoroughly tested to ensure reliability.
Required test coverage:
ensure_token_account: Test both scenarios where token account exists and needs creationget_token_balance: Test successful balance retrieval and handling of non-existent accounts
🔗 Analysis chain
Well-designed utility methods with clear responsibilities
Good addition of utility methods with proper error handling. However, these new public methods need test coverage.
Would you like me to help generate unit tests for these new methods?

🧹 Nitpick comments (11)
packages/libcheese/src/meteora.rs (7)
35-37: Potentially verbose or sensitive debug logging
Printing the entire raw response is great for debugging but may be verbose and could include sensitive data. Consider limiting the length or adding log levels.
38-38: Parse error handling
When parsing JSON, consider adding more contextual information to the error message to aid in debugging.
69-71: String-based token amount fields
Storing token amounts as strings could lead to repeated parsing. Consider storing them as numeric types to improve usability.
86-90: Flags for unknown and permissioned pools
Adding boolean flags is a neat approach, but clarify how or when these fields are enforced to maintain consistent behavior across the codebase.
94-96: Fee percentage stored as string
While storing the fee as a string can work, using a numeric type avoids extra parse steps and potential conversion errors.
197-206:MeteoraQuoteResponsestoring amounts as strings
Maintaining amounts asStringmay require frequent runtime parsing. Consider numeric fields to simplify calculations.
298-343: Hard-coded vault program string
While this may be correct for now, refactoring to consistently useget_vault_program()might reduce duplication and potential mismatches.packages/libcheese/src/solana.rs (4)
49-54: Detailed logs inexecute_trade
In-depth logging is beneficial, but consider using a structured logger if you find logs too verbose.
96-127: Enhanced debugging of accounts
Logging each account is extremely helpful but can be dense. For large-scale production, consider grouping logs or using structured data.
143-156: InlinedMeteoraSwapAccountsconstruction
Manually building the struct is fine. However, reusing the existingget_swap_accountsfromMeteoraPoolmight reduce code duplication.
224-247: Creating the token account with minimal error details
Consider improved error messages if account creation fails, possibly adding logs or context.

packages/libcheese/src/meteora.rs (9)
5-6: New imports for JSON and Pubkey
Importing serde_json::json and solana_sdk::pubkey::Pubkey looks standard and necessary for upcoming enhancements.
73-76: Defaulting token decimals and prices
Using #[serde(default)] ensures missing fields won't break deserialization. Verify that these defaults match the real-world data.
91-93: Fee volume default
Ensure that initializing fee_volume to 0.0 is intentional if the API doesn’t provide a fee volume.
97-108: Vault address fields as String
All vault fields are stored as strings and converted to Pubkey later. This can be fine for external JSON but might fail if an incorrect address is supplied. Make sure to validate or handle exceptions.
148-168: Parsing addresses in get_swap_accounts
Multiple .parse() calls on strings. Consider adding more context or using a utility to handle malformed addresses gracefully.
174-188: MeteoraSwapAccounts struct
The structure is consistent and straightforward, facilitating organized handling of swap-related accounts.
208-218: Request/response struct definitions
Using dedicated structs for requests and responses is a clean design choice, making the code more expressive.
243-250: Fee percentage fallback
Defaulting the fee to 0.3% hides parse errors. Consider explicitly handling unexpected values for easier debugging.
289-295: Ensuring pools exist before initialization
The check for Pool not found is good. Confirm that init_vault_fields() remains valid even with minimal pool data.
packages/libcheese/Cargo.toml (1)
15-18: Added dependencies: spl-token and lazy_static
Both additions look appropriate for token handling and static references.
packages/libcheese/src/common.rs (4)
1-4: Imports for lazy_static and HashSet
No issues with introducing lazy_static and HashSet, these are standard solutions for static references.
7-8: USDC_MINT constant
Defining USDC_MINT here is convenient for referencing in other modules, ensuring consistency throughout the codebase.
9-16: BLACKLISTED_MINTS static reference
Using lazy_static! for a set of blacklisted mints is a simple way to keep them accessible and immutable at runtime.
45-47: is_blacklisted function
This helper cleanly checks membership in the blacklist. Straightforward and effective.
packages/libcheese/src/solana.rs (7)
12-13: Importing token account utilities
get_associated_token_address and spl_token are essential for the new token operations.
17-17: Re-exporting Meteora references
No concerns. The link to MeteoraPool and MeteoraSwapAccounts is clear.
23-24: Making rpc_client and wallet public
Double-check the rationale for exposing these fields. It might be required for integration, but consider potential security or concurrency implications.
47-47: Switch from u64 to u16 for slippage
A narrower type for basis points is typically safer and more conventional.
160-173: Blockhash update & manual signing
Updating the blockhash and signing logic ensures transactions remain valid. This is a robust approach.
190-217: On-demand token account creation
Automatically creating the token account if it doesn’t exist is convenient, but watch for possible race conditions in concurrent trades.
298-320: Missing test coverage for account utility methods
Unit tests for ensure_token_account and get_token_balance remain essential.

🛠️ Refactor suggestion
Placeholder fields in init_vault_fields
Storing "placeholder" in production code can lead to confusion or runtime errors. Prefer more definitive logic for setting these vault fields or remove them if unused.
