Functions

func NewQuerier

Types

type Keeper 

type Keeper struct {

	// Ethermint concrete implementation on the EVM StateDB interface
	CommitStateDB *types.CommitStateDB
	// 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
	// contains filtered or unexported fields
}

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