Functions

func NewQuerier

Types

type BlockInnerData

type BlockInnerData = interface{}

type GovKeeper

type GovKeeper interface {
	GetDepositParams(ctx sdk.Context) govtypes.DepositParams
	GetVotingParams(ctx sdk.Context) govtypes.VotingParams
}

GovKeeper defines the expected gov Keeper

type Keeper

type Keeper struct {

	// Transaction counter in a block. Used on StateSB's Prepare function.
	// It is reset to 0 every block on BeginBlock so there's no point in storing the counter
	// on the KVStore or adding it as a field on the EVM genesis state.
	TxCount int
	Bloom   *big.Int
	Bhash   ethcmn.Hash
	LogSize uint
	Ada     types.DbAdapter

	LogsManages *LogsManager

	UpdatedAccount []ethcmn.Address

	Watcher *watcher.Watcher
	// contains filtered or unexported fields
}

Keeper wraps the CommitStateDB, allowing us to pass in SDK context while adhering to the StateDB interface.
