## Overview
|
|
|
|
The evmutil module provides additional functionalities on top of the evm module.
|
|
|
|
### EVM `akava` Usage
|
|
|
|
evmutil stores additional state data for evm accounts and exposes an `EvmBankKeeper` that should be used by the `x/evm` keeper for bank operations.
|
|
The purpose of the `EvmBankKeeper` is to allow the usage of the `akava` balance on the EVM via an account's existing `ukava` balance. This is needed because the EVM gas token use 18 decimals, and since `ukava` has 6 decimals, it cannot be used as the EVM gas denom directly.
|
|
|
|
For additional details on how balance conversions work, see **[Concepts](01_concepts.md)**.
|
|
|
|
### ERC20 Token <> sdk.Coin Conversion
|
|
|
|
evmutil exposes messages to allow for the conversion of Kava ERC20 tokens and sdk.Coins via a whitelist.
|
|
|
|
For additional details on how these messages work, see **[Messages](03_messages.md)**.
