# State
|
|
|
|
## Parameters and Genesis State
|
|
|
|
`Parameters` define the list of conversion pairs allowed to be converted between Kava ERC20 tokens and sdk.Coins.
|
|
|
|
```protobuf
|
|
// Params defines the evmutil module params
|
|
message Params {
|
|
// enabled_conversion_pairs defines the list of conversion pairs allowed to be
|
|
// converted between Kava ERC20 and sdk.Coin
|
|
repeated ConversionPair enabled_conversion_pairs = 4;
|
|
}
|
|
|
|
// ConversionPair defines a Kava ERC20 address and corresponding denom that is
|
|
// allowed to be converted between ERC20 and sdk.Coin
|
|
message ConversionPair {
|
|
// ERC20 address of the token on the Kava EVM
|
|
bytes kava_erc20_address = 1;
|
|
// Denom of the corresponding sdk.Coin
|
|
string denom = 2;
|
|
}
|
|
```
|
|
|
|
`GenesisState` defines the state that must be persisted when the blockchain stops/restarts in order for normal function of the evmutil module to resume.
|
|
|
|
```protobuf
|
|
message GenesisState {
|
|
repeated Account accounts = 1 [(gogoproto.nullable) = false];
|
|
Params params = 2 [(gogoproto.nullable) = false];
|
|
}
|
|
```
|
|
|
|
## Account
|
|
|
|
An `Account` is a struct representing the excess `akava` balance of an address.
|
|
|
|
Since an address's total `akava` balance is derived from its `ukava` balance and the excess `akava` balance stored by the `Account` struct, the `akava` balance here should never exceed 1 `ukava` (10^12 `akava`).
|
|
|
|
```protobuf
|
|
message Account {
|
|
bytes address = 1;
|
|
string balance = 2;
|
|
}
|
|
```
|
|
|
|
## Store
|
|
|
|
For complete implementation details for how items are stored, see [keys.go](../types/keys.go). `x/evmutil` store state consists of accounts.
