Functions

func MessageEventsForTransaction 

func MessageEventsForTransaction(
	ctx context.Context,
	ethConn Connector,
	contract eth_common.Address,
	chainId vaa.ChainID,
	tx eth_common.Hash) (uint64, []*common.MessagePublication, error)

MessageEventsForTransaction returns the lockup events for a given transaction. Returns the block number and a list of MessagePublication events.

func PadAddress 

func PadAddress(address common.Address) vaa.Address

PadAddress creates 32-byte VAA.Address from 20-byte Ethereum addresses by adding 12 0-bytes at the left
