var ConversionMultiplier = sdk.NewInt(1_000_000_000_000)

ConversionMultiplier is the conversion multiplier between akava and ukava

Functions

func AllInvariants 

func AllInvariants(bankK types.BankKeeper, k Keeper) sdk.Invariant

AllInvariants runs all invariants of the swap module

func FullyBackedInvariant 

func FullyBackedInvariant(bankK types.BankKeeper, k Keeper) sdk.Invariant

FullyBackedInvariant ensures all minor balances are backed by the coins in the module account.

The module balance can be greater than the sum of all minor balances. This can happen in rare cases where the evm module burns tokens.

func RegisterInvariants 

func RegisterInvariants(ir sdk.InvariantRegistry, bankK types.BankKeeper, k Keeper)

RegisterInvariants registers the swap module invariants

func SmallBalancesInvariant 

func SmallBalancesInvariant(_ types.BankKeeper, k Keeper) sdk.Invariant

SmallBalancesInvariant ensures all minor balances are less than the overflow amount, beyond this they should be converted to the major denom.

func SplitAkavaCoins 

func SplitAkavaCoins(coins sdk.Coins) (sdk.Coin, sdk.Int, error)

SplitAkavaCoins splits akava coins to the equivalent ukava coins and any remaining akava balance. An error will be returned if the coins are not valid or if the coins are not the akava denom.

func ValidateEvmCoins 

func ValidateEvmCoins(coins sdk.Coins) error

ValidateEvmCoins validates the coins from evm is valid and is the EvmDenom (akava).

Types

type EvmBankKeeper 

type EvmBankKeeper struct {
	// contains filtered or unexported fields
}

EvmBankKeeper is a BankKeeper wrapper for the x/evm module to allow the use of the 18 decimal akava coin on the evm. x/evm consumes gas and send coins by minting and burning akava coins in its module account and then sending the funds to the target account. This keeper uses both the ukava coin and a separate akava balance to manage the extra percision needed by the evm.

func NewEvmBankKeeper 

func NewEvmBankKeeper(akavaKeeper Keeper, bk types.BankKeeper, ak types.AccountKeeper) EvmBankKeeper

func (EvmBankKeeper) BurnCoins 

func (k EvmBankKeeper) BurnCoins(ctx sdk.Context, moduleName string, amt sdk.Coins) error

BurnCoins burns akava coins by burning the equivalent ukava coins and any remaining akava coins. It will panic if the module account does not exist or is unauthorized.

func (EvmBankKeeper) ConvertAkavaToUkava 

func (k EvmBankKeeper) ConvertAkavaToUkava(ctx sdk.Context, addr sdk.AccAddress) error

ConvertAkavaToUkava converts all available akava to ukava for a given AccAddress.

func (EvmBankKeeper) ConvertOneUkavaToAkavaIfNeeded 

func (k EvmBankKeeper) ConvertOneUkavaToAkavaIfNeeded(ctx sdk.Context, addr sdk.AccAddress, akavaNeeded sdk.Int) error

ConvertOneUkavaToAkavaIfNeeded converts 1 ukava to akava for an address if its akava balance is smaller than the akavaNeeded amount.

func (EvmBankKeeper) GetBalance 

func (k EvmBankKeeper) GetBalance(ctx sdk.Context, addr sdk.AccAddress, denom string) sdk.Coin

GetBalance returns the total **spendable** balance of akava for a given account by address.

func (EvmBankKeeper) GetModuleAddress 

func (k EvmBankKeeper) GetModuleAddress(moduleName string) sdk.AccAddress

func (EvmBankKeeper) MintCoins 

func (k EvmBankKeeper) MintCoins(ctx sdk.Context, moduleName string, amt sdk.Coins) error

MintCoins mints akava coins by minting the equivalent ukava coins and any remaining akava coins. It will panic if the module account does not exist or is unauthorized.

func (EvmBankKeeper) SendCoinsFromAccountToModule 

func (k EvmBankKeeper) SendCoinsFromAccountToModule(ctx sdk.Context, senderAddr sdk.AccAddress, recipientModule string, amt sdk.Coins) error

SendCoinsFromAccountToModule transfers akava coins from an AccAddress to a ModuleAccount. It will panic if the module account does not exist.

func (EvmBankKeeper) SendCoinsFromModuleToAccount 

func (k EvmBankKeeper) SendCoinsFromModuleToAccount(ctx sdk.Context, senderModule string, recipientAddr sdk.AccAddress, amt sdk.Coins) error

SendCoinsFromModuleToAccount transfers akava coins from a ModuleAccount to an AccAddress. It will panic if the module account does not exist. An error is returned if the recipient address is black-listed or if sending the tokens fails.

type Keeper 

type Keeper struct {
	// contains filtered or unexported fields
}

Keeper of the evmutil store. This keeper stores additional data related to evm accounts.

func NewKeeper 

func NewKeeper(cdc codec.Codec, storeKey sdk.StoreKey) Keeper

NewKeeper creates an evmutil keeper.

func (Keeper) AddBalance 

func (k Keeper) AddBalance(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Int) error

AddBalance increments the akava balance of an address.

func (Keeper) GetAccount 

func (k Keeper) GetAccount(ctx sdk.Context, addr sdk.AccAddress) *types.Account

GetAccount returns the account for a given address.

func (Keeper) GetAllAccounts 

func (k Keeper) GetAllAccounts(ctx sdk.Context) (accounts []types.Account)

GetAllAccounts returns all accounts.

func (Keeper) GetBalance 

func (k Keeper) GetBalance(ctx sdk.Context, addr sdk.AccAddress) sdk.Int

GetBalance returns the total balance of akava for a given account by address.

func (Keeper) IterateAllAccounts 

func (k Keeper) IterateAllAccounts(ctx sdk.Context, cb func(types.Account) bool)

IterateAllAccounts iterates over all accounts. If true is returned from the callback, iteration is halted.

func (Keeper) RemoveBalance 

func (k Keeper) RemoveBalance(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Int) error

RemoveBalance decrements the akava balance of an address.

func (Keeper) SendBalance 

func (k Keeper) SendBalance(ctx sdk.Context, senderAddr sdk.AccAddress, recipientAddr sdk.AccAddress, amt sdk.Int) error

SendBalance transfers the akava balance from sender addr to recipient addr.

func (Keeper) SetAccount 

func (k Keeper) SetAccount(ctx sdk.Context, account types.Account) error

SetAccount sets the account for a given address.

func (Keeper) SetBalance 

func (k Keeper) SetBalance(ctx sdk.Context, addr sdk.AccAddress, bal sdk.Int) error
