Backend implements the functionality shared within namespaces. Implemented by EVMBackend.

type EVMBackend 

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

EVMBackend implements the Backend interface

func NewEVMBackend 

func NewEVMBackend(ctx *server.Context, logger log.Logger, clientCtx client.Context) *EVMBackend

NewEVMBackend creates a new EVMBackend instance

func (*EVMBackend) BlockBloom 

func (e *EVMBackend) BlockBloom(height *int64) (ethtypes.Bloom, error)

BlockBloom query block bloom filter from block results

func (*EVMBackend) BlockNumber 

func (e *EVMBackend) BlockNumber() (hexutil.Uint64, error)

BlockNumber returns the current block number in abci app state. Because abci app state could lag behind from tendermint latest block, it's more stable for the client to use the latest block number in abci app state than tendermint rpc.

func (*EVMBackend) BloomStatus 

func (e *EVMBackend) BloomStatus() (uint64, uint64)

BloomStatus returns the BloomBitsBlocks and the number of processed sections maintained by the chain indexer.

func (*EVMBackend) ChainConfig added in v0.6.1 

func (e *EVMBackend) ChainConfig() *params.ChainConfig

ChainConfig return the ethereum chain configuration

func (*EVMBackend) CurrentHeader added in v0.6.1 

func (e *EVMBackend) CurrentHeader() *ethtypes.Header

CurrentHeader returns the latest block header

func (e *EVMBackend) EthBlockFromTendermint(
	block *tmtypes.Block,
	fullTx bool,
) (map[string]interface{}, error)

EthBlockFromTendermint returns a JSON-RPC compatible Ethereum block from a given Tendermint block and its block result.

func (*EVMBackend) GetBlockByHash
