9-9: Import added for feemarket store key deletion.

This import is necessary to reference the feemarket module's store key that will be deleted during the v11 upgrade.

---

29-31:

✅ Verification successful

Properly marking feemarket store for deletion during upgrade.

The feemarket store key is correctly added to the list of stores to be deleted during the v11 upgrade, which ensures proper cleanup of the module's state as part of the module removal.

---

🏁 Script executed:

#!/bin/bash
# Verify that there are no remaining references to the feemarket store key in new code
# that might attempt to access a store that will be deleted

rg -i "feemarket.(Store|Module)" --type go --glob "!app/upgrades/**"

I’ll perform a broader search for any remaining feemarket references outside the upgrade code:

This will help confirm that no code still depends on the feemarket store being present.

#!/bin/bash
# Search for any references to 'feemarket' outside the app/upgrades directory

v11 upgrade: Remove feemarket store

The feemarkettypes.StoreKey is now correctly included in the Deleted slice in app/upgrades/v11/constants.go, ensuring the fee-market module’s KV store is cleaned up during migration. A code-wide search confirms there are no remaining references to feemarket outside the upgrade logic.

app/keepers/keepers.go (2)

31-32: Import reorganization after feemarket removal.

These import lines have been reorganized after removing feemarket-related imports. The imports are now properly sorted and maintained.

Also applies to: 37-37, 45-45, 61-64

---

108-177: FeeMarketKeeper field removed from AppKeepers struct.

The AppKeepers struct no longer contains a FeeMarketKeeper field, which is consistent with the removal of the feemarket module.

ante/ante.go (4)

4-4: Standard bank keeper import replaces feemarket imports.

The feemarket imports have been replaced with the standard Cosmos SDK bank keeper import, which is appropriate since the ante handler will now use the standard fee handling mechanisms.

---

35-37: HandlerOptions struct simplified.

The HandlerOptions struct now uses the standard account and bank keepers instead of feemarket-specific options. This simplifies the ante handler interface and removes dependency on the feemarket module.

---

44-56: Simplified AnteHandler validation.

The AnteHandler validation logic remains robust with appropriate error checking for the required keepers. The removal of feemarket-specific validation maintains code quality while simplifying the implementation.

---

67-82:

✅ Verification successful

Removed feemarket decorators from ante handler chain.

The ante decorator chain has been simplified by removing the feemarket-specific decorators. Transaction fee validation and deduction will now use the standard Cosmos SDK mechanisms.

---

🏁 Script executed:

#!/bin/bash
# Check if there are any remaining references to feemarket decorators in the codebase
# This helps verify that all usage points have been cleaned up

rg "feemarket.(NewMinGasPriceDecorator|NewDeductFeeDecorator)" --type go

Length of output: 74

---

🏁 Script executed:

#!/bin/bash
# Search for any remaining references to 'feemarket' across the repository
rg "feemarket" -n .

Length of output: 437

---

Confirmed: Feemarket decorators fully removed

• No occurrences of NewMinGasPriceDecorator or NewDeductFeeDecorator remain in the codebase.
• The only remaining feemarket references are in app/upgrades/v11/constants.go (for upgrade constants) and in go.mod/go.sum, which are expected for the v11 upgrade.

All feemarket-specific ante decorators have been cleaned up—approving these changes.
