from the changs in #2086, this pull request implements a new `JournalChange`
struct that saves a deep copy of the state multi store before each
state-modifying, Nibiru-specific precompiled contract is called (`OnRunStart`).
Additionally, we commit the `StateDB` there as well. This guarantees that the
non-EVM and EVM state will be in sync even if there are complex, multi-step
Ethereum transactions, such as in the case of an EthereumTx that influences the
`StateDB`, then calls a precompile that also changes non-EVM state, and then EVM
reverts inside of a try-catch.

This line's required to appease the module manager when it does a type assertion on an object of type bankkeeper.Keeper (an interface), asserting that it's actually a bankkeeper.BaseKeeper struct. I didn't see a simple way to force x/bank to use the NibiruBankKeeper struct without editing the Bank module directly, so I opted for what's written here, which is quite simple.

Edit: Moved the NibiruBankKeeper to #2095. The rationale behind these lines are in that PR

capability.NewAppModule(appCodec, *app.capabilityKeeper, false),
feegrantmodule.NewAppModule(appCodec, app.AccountKeeper, app.BankKeeper, app.FeeGrantKeeper, app.interfaceRegistry),

💡 Codebase verification

Direct statedb.New usage needs to be migrated to EvmKeeper.NewStateDB

Found inconsistent StateDB creation patterns that should be standardized:

  • app/evmante/evmante_can_transfer.go: Uses direct statedb.New instead of EvmKeeper.NewStateDB
  • x/evm/statedb/statedb_test.go: Uses direct statedb.New in tests

The only legitimate direct usage is in x/evm/keeper/statedb.go which implements the NewStateDB method itself.

🔗 Analysis chain

LGTM! Improved StateDB creation pattern.

This change properly delegates StateDB creation to EvmKeeper, ensuring test scenarios use the same state management path as production code. This alignment strengthens test reliability and supports the PR's goal of safer state handling.

Let's verify consistent StateDB creation patterns across the codebase:

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for any direct statedb.New calls that should use EvmKeeper.NewStateDB
# Expected: Only EvmKeeper should directly call statedb.New

# Search for direct statedb.New usage
echo "Checking for direct statedb.New usage..."
rg "statedb\.New\(" -A 3

# Search for EvmKeeper.NewStateDB usage
echo "Checking for EvmKeeper.NewStateDB usage..."

🛠️ Refactor suggestion

Consider adding input validation and refactoring common field assignments.

The function is well-documented and handles different transaction types correctly. Consider these improvements:

  1. Add validation for the value parameter to prevent potential issues with nil or negative values.
  2. Extract common field assignments to reduce code duplication.

Here's a suggested refactoring:

 func NewEthTxMsgFromTxData(
     deps *TestDeps,
     txType GethTxType,
     innerTxData []byte,
     nonce uint64,
     to *gethcommon.Address,
     value *big.Int,
     gas uint64,
     accessList gethcore.AccessList,
 ) (*evm.MsgEthereumTx, error) {
+    if value == nil {
+        return nil, fmt.Errorf("value cannot be nil")
+    }
+    if value.Sign() < 0 {
+        return nil, fmt.Errorf("negative value not allowed")
+    }
+
     if innerTxData == nil {
         innerTxData = []byte{}
     }
 
+    // Common fields for all transaction types
+    commonFields := struct {
+        nonce uint64
+        data  []byte
+        to    *gethcommon.Address
+        value *big.Int
+        gas   uint64
+    }{nonce, innerTxData, to, value, gas}
+

         innerTx := TxTemplateLegacyTx()

-        innerTx.Data = innerTxData
-        innerTx.To = to
