1-124: Overall, the changes look good and address the PR objectives.The implementation of the singleton pattern for
StoreKeyshould effectively resolve the issues mentioned in the PR objectives. The changes are minimal and focused, which reduces the risk of introducing new problems.A few points to consider for future improvements:
- Document the rationale behind the singleton pattern in a comment, as suggested earlier.
- Consider adding unit tests to verify the singleton behavior of
StoreKey.- If not already done, update any documentation that might reference the old
StoreKeyimplementation.
34-36: LGTM! Verify usage across the codebase.The modification to
ProvideKVStoreKeyfunction effectively implements the singleton pattern forStoreKey. This change addresses the issue mentioned in the PR objectives where multiple calls to this function were causing problems.To ensure this change doesn't introduce any unexpected behavior, let's verify the usage of
ProvideKVStoreKeyacross the codebase:This script will help us ensure that:
- All usages of
ProvideKVStoreKeyare still valid with the new implementation.- There are no remaining direct instantiations of
storetypes.NewKVStoreKeythat should be replaced withProvideKVStoreKey.Verification successful
Verified! All usages of
ProvideKVStoreKeyare correctly updated, and there are no direct instantiations ofstoretypes.NewKVStoreKeyremaining in the active codebase.Scripts executed
The following scripts were executed for the analysis:

LGTM! Consider adding a brief comment explaining the singleton pattern.
The introduction of a global storeKey variable aligns well with the PR objective of making StoreKey a singleton. This change should effectively prevent issues arising from multiple instantiations of the key.
Consider adding a brief comment explaining why the singleton pattern is used here. This can help future maintainers understand the rationale behind this design decision. For example:
//nolint:gochecknoglobals // storeKey is a singleton.
+// Using a singleton pattern ensures that only one instance of the StoreKey is used
+// throughout the application, preventing issues with multiple instantiations.
var storeKey = storetypes.NewKVStoreKey("beacon")Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

StoreKeyis used as index in cosmos sdk DB code. Notably the whole struct is used as index, not its content; this means that if we callProvideKVStoreKeytwice (thus currently re-instantiating a key with the same content), the lookup by storeKey fails and its store may not be found, even if the store key content is the very same.This is hardly an issue in beaconKit but it costed me some debugging time while trying wiring miniAvalanche in.
The change I propose here makes the storeKey a singleton and guards against nasty issue which would happen if
