-In order to use the EVM and be compatible with existing clients, the gas denom used by the EVM must be in 18 decimals. Since `ukava` has 6 decimals of precision, it cannot be used as the EVM gas denom directly.
-
-To use the Kava token on the EVM, the evmutil module provides an `EvmBankKeeper` that is responsible for the conversion of `ukava` and `akava`. A user's excess `akava` balance is stored in the `x/evmutil` store, while its `ukava` balance remains in the cosmos-sdk `x/bank` module.
-
-## `EvmBankKeeper` Overview
-
-The `EvmBankKeeper` provides access to an account's total `akava` balance and the ability to transfer, mint, and burn `akava`. If anything other than the `akava` denom is requested, the `EvmBankKeeper` will panic.
-
-This keeper implements the `x/evm` module's `BankKeeper` interface to enable the usage of `akava` denom on the EVM.
-
-### `x/evm` Parameter Requirements
-
-Since the EVM denom `akava` is required to use the `EvmBankKeeper`, it is necessary to set the `EVMDenom` param of the `x/evm` module to `akava`.
-
-### Balance Calculation of `akava`
-
-The `akava` balance of an account is derived from an account's **spendable** `ukava` balance times 10^12 (to derive its `akava` equivalent), plus the account's excess `akava` balance that can be accessed via the module `Keeper`.
-
-### `akava` <> `ukava` Conversion
-
-When an account does not have sufficient `akava` to cover a transfer or burn, the `EvmBankKeeper` will try to swap 1 `ukava` to its equivalent `akava` amount. It does this by transferring 1 `ukava` from the sender to the `x/evmutil` module account, then adding the equivalent `akava` amount to the sender's balance in the module state.
-
-In reverse, if an account has enough `akava` balance for one or more `ukava`, the excess `akava` balance will be converted to `ukava`. This is done by removing the excess `akava` balance in the module store, then transferring the equivalent `ukava` coins from the `x/evmutil` module account to the target account.
-
-The swap logic ensures that all `akava` is backed by the equivalent `ukava` balance stored in the module account.

-
-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.
