Functions

func EthBlockFromTendermint 

func EthBlockFromTendermint(clientCtx clientcontext.Context, block *tmtypes.Block, transactions []common.Hash) (map[string]interface{}, error)

EthBlockFromTendermint returns a JSON-RPC compatible Ethereum blockfrom a given Tendermint block.

Types

type Account 

type Account struct {
	Nonce     *hexutil.Uint64              `json:"nonce"`
	Code      *hexutil.Bytes               `json:"code"`
	Balance   **hexutil.Big                `json:"balance"`
	State     *map[common.Hash]common.Hash `json:"state"`
	StateDiff *map[common.Hash]common.Hash `json:"stateDiff"`
}

Account indicates the overriding fields of account during the execution of a message call. NOTE: state and stateDiff can't be specified at the same time. If state is set, message execution will only use the data in the given state. Otherwise if statDiff is set, all diff will be applied first and then execute the call message.

type BlockNumber 

type BlockNumber int64

BlockNumber represents decoding hex string to block values

func NewBlockNumber 

func NewBlockNumber(n *big.Int) BlockNumber

func (BlockNumber) Int64 

func (bn BlockNumber) Int64() int64

Int64 converts block number to primitive types

func (BlockNumber) TmHeight 

func (bn BlockNumber) TmHeight() *int64

TmHeight is a util function used for the Tendermint RPC clients. It returns nil if the block number is "latest". Otherwise, it returns the pointer of the int64 value of the height.

func (*BlockNumber) UnmarshalJSON
