🧹 Nitpick comments (5)
packages/libcheese/src/meteora.rs (1)
210-316: Use named constants for discriminators and avoid creating RpcClient frequently
Your transaction-building logic is well-structured. For clarity, store the 8-byte Anchor discriminator ([248, 198, 158, 145, 225, 117, 135, 200]) in a constant, rather than inlining. Also, be mindful of repeatedly creating newRpcClients in an async context if usage grows.packages/libcheese/src/solana.rs (1)
165-188: Ensure token account logic
This new method greatly improves user experience. However, in highly concurrent scenarios, two calls might race to create the same associated token account. The ATA program is usually idempotent, but it is advisable to handle “already in use” errors gracefully as well.packages/cli/src/main.rs (3)
427-435: Detailed trade logs
In-depth logging helps with debugging and transparency. If logs become too verbose, consider using a debug or trace level for production environments.
Line range hint
457-506: Consider refactoring repeated trade steps (sell path)
This sell path includes multiple sequences ofexecute_tradecalls, which mirror those in the buy path. A helper function could reduce this duplication and cut down on future maintenance costs.
Line range hint
512-555: Similar repeated code for the buy path
The buy path reiterates many of the same trade steps. Refactoring both paths into a shared routine would simplify updates if the trade flow changes.

packages/libcheese/src/meteora.rs (4)
2-20: Simplify your imports if possible
The newly added imports appear correct, but you might consider whether importing all of anchor_lang::prelude::* introduces unused symbols. Minimizing import namespaces can improve clarity, though it is mostly a stylistic preference.
21-22: Confirm hardcoded program IDs
If these program IDs differ between mainnet, devnet, or test environments, consider centralizing them in a config file or using environment variables to avoid accidental usage of invalid IDs.
24-27: Helper function is correct
Conversion from anchor's Pubkey to solana_sdk::pubkey::Pubkey is straightforward and accurate.
122-203: Ensure correct token count before indexing
This function assumes exactly two tokens in the pool. If future usage introduces pools with a different number of tokens, there is a risk of out-of-bounds indexing. Consider validating that the pool’s token mint list has length two before indexing.
packages/libcheese/src/solana.rs (3)
88-90: Aligned call to updated function signature
Passing the &MeteoraPool object completes the switch away from the string pool address, matching the new get_meteora_quote signature.
97-103: New swap transaction parameters verified
Providing &self.rpc_client and &self.wallet aligns with the updated get_meteora_swap_transaction requirements.
Line range hint 107-116: Enhanced step-by-step transaction flow comments
These updated comments make the high-level transaction process easier to follow.
packages/cli/src/main.rs (3)
367-376: Skipping derived pools ensures consistency
By ignoring derived pools, you minimize the chance of performing trades in incomplete or intermediate states. If future requirements change, consider how or when to handle them gracefully.
443-447: Verbose pool details
These extra print statements provide important clarity. Stay mindful about logging sensitive user data when shifting to production.
448-454: Proactive account checks
Ensuring the associated token accounts exist preemptively prevents downstream trade failures. This is an excellent practice.
packages/cli/Cargo.toml (1)
2-2: Renaming package to ‘cheese’
Renaming the package clarifies branding alignment with the rest of the codebase. Ensure build scripts and references to the old name are updated as needed.
packages/libcheese/Cargo.toml (1)
12-21: Pinning or downgrading dependencies
Lowering Solana crates to 1.14 and adding new libraries can have downstream impacts on feature compatibility and security. Confirm that no important security updates are missed in these pinned versions.
