rg "\.IsEqual\(" --type go

# Search for Equal usage pattern to verify consistency
echo -e "\nVerifying Equal usage:"
rg "\.Equal\(" --type go

Line range hint 60-64: Verify module initialization order

The changes to genesisModuleOrder look correct as they:

1. Maintain the required ordering (genutils after staking and auth)
2. Remove the capability module (which is expected as part of cosmos-sdk v0.50.10)
3. Add the new modules in a logical order

However, let's verify that this order is consistent with other cosmos-sdk v0.50.10 applications.

#!/bin/bash
# Description: Search for similar module initialization patterns in the codebase

# Look for other files that might define module initialization order
rg -l "genesisModuleOrder.*=.*\[" --type go

# Look for any documentation about module ordering
fd -t f "README.md" | xargs rg -l "module.*order"

27-29: Verify the necessity of newly added imports

The addition of evidence, feegrant, and upgrade type imports aligns with the cosmos-sdk v0.50.10 upgrade. However, let's verify that these modules are actually used in the codebase.

#!/bin/bash
# Description: Check if the newly added modules are used in the codebase

echo "Checking usage of evidence module..."
rg -l "evidencetypes\." --type go

echo "Checking usage of feegrant module..."
rg -l "feegrant\." --type go

echo "Checking usage of upgrade module..."
rg -l "upgradetypes\." --type go

#!/bin/bash

# Check for evidence module configuration and usage
echo "Checking evidence module configuration..."
rg -A 5 "evidence" modules/service/keeper/depinject_test.go

# Check for feegrant module configuration and usage
echo "Checking feegrant module configuration..."
rg -A 5 "feegrant" modules/service/keeper/depinject_test.go

# Check for upgrade module configuration and usage
echo "Checking upgrade module configuration..."
rg -A 5 "upgrade" modules/service/keeper/depinject_test.go

# Check if these modules are part of the module initialization order
echo "Checking module initialization order..."
rg "genesisModuleOrder.*=.*\[.*\]" modules/service/keeper/depinject_test.go

215-226: ⚠️ Potential issue

Critical: Incomplete modification of transaction query logic

The changes to the query logic raise several concerns:

1. The event filtering logic has been commented out without providing an alternative filtering mechanism
2. The QueryTxsByEvents call now uses empty strings for both parameters, effectively removing all filtering
3. This could lead to:
   • Performance degradation due to querying all transactions without filters
   • Incorrect results by potentially returning unrelated transactions
   • Unnecessary exposure of transaction data

Consider one of these approaches:

-	//events := []string{
-	//	fmt.Sprintf(
-	//		"%s.%s='%s'",
-	//		types.EventTypeRespondService,
-	//		types.AttributeKeyRequestID,
-	//		[]byte(fmt.Sprintf("%d", requestID)),
-	//	),
-	//}
-	result, err := authtx.QueryTxsByEvents(cliCtx, 1, 1, "", "")

+	// Option 1: Update event query format for SDK v0.50.x
+	events := []string{
+		fmt.Sprintf("%s='%s'", 
+			sdk.EventTypeMessage,
+			types.EventTypeRespondService,
+		),
+		fmt.Sprintf("%s.%s='%s'",
+			types.EventTypeRespondService,
+			types.AttributeKeyRequestID,
+			requestID.String(),
+		),
+	}
+	result, err := authtx.QueryTxsByEvents(cliCtx, 1, 1, strings.Join(events, " AND "), "")

+	// Option 2: Use the new query API if available in SDK v0.50.x
+	query := client.NewEventQueryBuilder().
+		AddEvent(types.EventTypeRespondService).
+		AddAttribute(types.AttributeKeyRequestID, requestID.String())
+	result, err := authtx.QueryTxsByEvents(cliCtx, 1, 1, query.Build(), "")

Let's verify the correct event query format in Cosmos SDK v0.50.x:

#!/bin/bash
# Search for examples of QueryTxsByEvents usage in the codebase
rg "QueryTxsByEvents.*\".*\".*\"" --type go -A 2 -B 2

# Search for event query construction patterns
rg "EventTypeMessage|AddEvent|NewEventQueryBuilder" --type go -A 2 -B 2
