Poem

🐰 I hopped through code with a keen little eye,
Found a typo asleep in a Makefile nearby.
I nudged in middleware, tidy and neat,
Fixed a small word and kept builds upbeat.
Hooray for small fixes — a carrot-sized feat! 🥕

x/cronos/rpc/api.go (1)

29-36: Add missing doc comment and fix grammar in ReplayBlock function.

The codebase's golangci-lint configuration explicitly excludes exported comment warnings, so these are not lint failures. However, adding a doc comment for the exported constant ExceedBlockGasLimitError and correcting the grammar in the ReplayBlock function's comment would improve code quality and consistency.

 const (
 	// CronosNamespace is the extension RPC namespace of cronos module.
 	CronosNamespace = "cronos"

 	apiVersion = "1.0"

+	// ExceedBlockGasLimitError is a substring used to detect block gas limit exceed errors from tx logs.
 	ExceedBlockGasLimitError = "out of gas in location: block gas meter; gasWanted:"
 )

-// ReplayBlock return tx receipts by replay all the eth transactions,
+// ReplayBlock returns tx receipts by replaying all the eth transactions,
 // if postUpgrade is true, the tx that exceeded block gas limit is treated as reverted, otherwise as committed.
 func (api *CronosAPI) ReplayBlock(blockNrOrHash rpctypes.BlockNumberOrHash, postUpgrade bool) ([]map[string]interface{}, error) {

188-212: Comment tweak is clear and accurate (sender/receiver addresses).
No behavioral impact; this improves readability around the receipt fields.

---

321-345: Same readability win in ReplayBlock receipt construction.
Keeps the receipt field intent obvious; no functional change.
