Functions

func BlockMaxGasFromConsensusParams 

func BlockMaxGasFromConsensusParams(ctx context.Context, clientCtx client.Context) (int64, error)

BlockMaxGasFromConsensusParams returns the gas limit for the latest block from the chain consensus params.

func ContextWithHeight 

func ContextWithHeight(height int64) context.Context

ContextWithHeight wraps a context with the a gRPC block height header. If the provided height is 0, it will return an empty context and the gRPC query will use the latest block height for querying.

EthHeaderFromTendermint is an util function that returns an Ethereum Header from a tendermint Header.

func EthTransactionsFromTendermint
