3445-3460: Enhance unit test coverage forcreate_evm_inputfunctionThe current test case in
test_evm_inputconfirms the functionality for standard input values. To ensure robustness, consider adding test cases for edge conditions, such as:
- Empty strings for
denomandreceiver- Maximum string lengths
- Inputs where the length is exactly a multiple of 32 bytes
This will help verify that
create_evm_inputhandles all scenarios correctly.

53-53: LGTM: Added new EVM VM type constant
The new constant EVM: u8 = 2 is correctly defined and aligns with existing VM type constants. This addition allows for proper identification of the EVM type within the module.
1028-1028: Include EVM in VM type validation
Updating the create_pool function to include EVM in the VM type validation ensures that EVM is accepted as a valid vm_type. The logical condition is correctly extended.
2314-2316: Extended IBCMemo struct to support EVM messages
The addition of the evm: Option<MemoEvm> field in the IBCMemo struct effectively extends support for EVM messages. This change maintains consistency with existing optional fields (wasm and _move_).
2360-2375: Defined new structs for EVM message handling
The newly introduced structs MemoEvm, MemoEvmMessage, and MemoEvmAccessList are correctly defined to encapsulate EVM-specific message data. Field types and structures align with expected EVM message formats, facilitating proper communication with EVM contracts.
2393-2394: Initialized evm field in generate_ibc_message
Setting evm: option::none() during initialization ensures that the IBCMemo struct starts without EVM message data by default, maintaining consistency across different VM types.
2436-2448: Added EVM message generation in generate_ibc_message
The generate_ibc_message function now handles the EVM case by populating the memo.evm field with EVM-specific message data. The use of create_evm_input to generate the ABI-encoded input is appropriate, and assigning hook_contract as the ibc_receiver is consistent with expected behavior.

53-53: LGTM: EVM type constant follows existing pattern
The EVM constant is correctly defined with value 2, following the existing pattern of VM type constants.
1028-1031: LGTM: VM type validation properly includes EVM
The validation logic correctly checks for all supported VM types (MOVE, COSMWASM, EVM) with appropriate error handling.
2314-2315: LGTM: IBCMemo struct properly extended for EVM support
The IBCMemo struct is correctly updated to include an optional EVM field, maintaining consistency with the existing pattern.
2360-2374: LGTM: EVM message structs are well-structured
The EVM-related structs (MemoEvm, MemoEvmMessage, MemoEvmAccessList) are properly designed to handle EVM transactions with all necessary fields.
2436-2448: LGTM: EVM message generation properly implemented
The EVM message generation logic correctly constructs the message with appropriate contract address and input data.
2457-2481: LGTM: EVM input creation properly implements ABI encoding
The create_evm_input function correctly implements the EVM ABI encoding for the minitswapHook function, including proper parameter encoding and alignment.
3446-3460: LGTM: Comprehensive test case for EVM input encoding
The test case thoroughly validates the EVM input encoding with realistic data, including proper verification of the function selector and parameter encoding.

3446-3460: Consider adding more EVM-related testsWhile the basic EVM input encoding test is good, consider adding tests for:
- EVM message generation with different parameter combinations
- Edge cases in EVM input encoding
- Integration tests for the complete EVM message flow

53-53: LGTM: EVM type integration
The EVM constant is properly defined and integrated into the VM type validation alongside existing MOVE and COSMWASM types.
Also applies to: 1028-1031
2314-2315: LGTM: IBCMemo struct update
The IBCMemo struct is correctly extended to support EVM messages while maintaining compatibility with existing MOVE and COSMWASM message types through optional fields.
2360-2374: LGTM: EVM message structures
The EVM message structures are well-designed with:
- Proper separation of concerns between message and access list
- Required fields for EVM contract interaction (contract_addr, input, value)
- Support for EVM access lists to optimize gas usage
2483-2496: Fix padding logic in pad_zero function
The padding logic is now correct, handling cases where the input length is a multiple of 32 bytes properly. This matches the Ethereum ABI specification.
2436-2448: LGTM: EVM message generation integration
The EVM message generation is well-integrated into the existing message handling logic with:
- Proper contract address handling
- Correct input encoding using the EVM ABI format
- Empty access list by default for standard transactions
