Functions ¶
func AllTxLogsFromEvents ¶
AllTxLogsFromEvents parses all ethereum logs from cosmos events
func ParseTxLogsFromEvent ¶
ParseTxLogsFromEvent parse tx logs from one event
Types ¶
type Backend ¶
type Backend struct {
// contains filtered or unexported fields
}
Backend implements the BackendI interface
func NewBackend ¶
NewBackend creates a new Backend instance for cosmos and ethereum namespaces
func (*Backend) BaseFee ¶
BaseFee returns the base fee tracked by the Fee Market module. If the base fee is not enabled globally, the query returns nil. If the London hard fork is not activated at the current height, the query will return nil.
func (*Backend) BlockBloom ¶
BlockBloom query block bloom filter from block results
func (*Backend) BlockByHash ¶
BlockByHash returns the block identified by hash.
func (*Backend) BlockByNumber ¶
BlockByNumber returns the block identified by number.
func (*Backend) BlockNumber ¶
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 (*Backend) BloomStatus ¶
BloomStatus returns the BloomBitsBlocks and the number of processed sections maintained by the chain indexer.
func (*Backend) ChainConfig ¶
func (b *Backend) ChainConfig() *params.ChainConfig

CurrentHeader returns the latest block header
func (*Backend) EstimateGas ¶
func (b *Backend) EstimateGas(args evmtypes.TransactionArgs, blockNrOptional *types.BlockNumber) (hexutil.Uint64, error)
EstimateGas returns an estimate of gas usage for the given smart contract call.
func (*Backend) EthBlockFromTendermint ¶
func (b *Backend) 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 (*Backend) EthBlockFromTm ¶
func (*Backend) FeeHistory ¶
func (b *Backend) FeeHistory( userBlockCount rpc.DecimalOrHex, lastBlock rpc.BlockNumber, rewardPercentiles []float64, ) (*types.FeeHistoryResult, error)
FeeHistory returns data relevant for fee estimation based on the specified range of blocks.
func (*Backend) GetBlockByHash ¶
GetBlockByHash returns the block identified by hash.
func (*Backend) GetBlockByNumber ¶
func (b *Backend) GetBlockByNumber(blockNum types.BlockNumber, fullTx bool) (map[string]interface{}, error)
GetBlockByNumber returns the block identified by number.
func (*Backend) GetCoinbase ¶
func (b *Backend) GetCoinbase() (sdk.AccAddress, error)
GetCoinbase is the address that staking rewards will be send to (alias for Etherbase).
func (*Backend) GetEthereumMsgsFromTendermintBlock ¶
func (b *Backend) GetEthereumMsgsFromTendermintBlock(block *tmrpctypes.ResultBlock, blockRes *tmrpctypes.ResultBlockResults) []*evmtypes.MsgEthereumTx
GetEthereumMsgsFromTendermintBlock returns all real MsgEthereumTxs from a Tendermint block. It also ensures consistency over the correct txs indexes across RPC endpoints
func (*Backend) GetLogs ¶
GetLogs returns all the logs from all the ethereum transactions in a block.
func (*Backend) GetLogsByHeight ¶
GetLogsByHeight returns all the logs from all the ethereum transactions in a block.

GetTransactionByHash returns the Ethereum format transaction identified by Ethereum transaction hash
func (*Backend) GetTransactionCount ¶
func (b *Backend) GetTransactionCount(address common.Address, blockNum types.BlockNumber) (*hexutil.Uint64, error)
GetTransactionCount returns the number of transactions at the given address up to the given block number.
func (*Backend) GetTxByEthHash ¶
GetTxByEthHash uses `/tx_query` to find transaction by ethereum tx hash TODO: Don't need to convert once hashing is fixed on Tendermint https://github.com/tendermint/tendermint/issues/6539
func (*Backend) GetTxByTxIndex ¶
GetTxByTxIndex uses `/tx_query` to find transaction by tx index of valid ethereum txs
