var UseiToSweiMultiplier = big.NewInt(1_000_000_000_000)

UseiToSweiMultiplier Fields that were denominated in usei will be converted to swei (1usei = 10^12swei) for existing Ethereum application (which assumes 18 decimal points) to display properly.

Functions

func GetCoinbaseAddress 

func GetCoinbaseAddress(txIdx int) sdk.AccAddress

func SplitUseiWeiAmount 

func SplitUseiWeiAmount(amt *big.Int) (sdk.Int, sdk.Int)

func TransferWithoutEvents

Types

type DBImpl 

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

Initialized for each transaction individually

func NewDBImpl 

func NewDBImpl(ctx sdk.Context, k EVMKeeper, simulation bool) *DBImpl

func (*DBImpl) AddAddressToAccessList
