Functions

func DiscoverAddresses

func DiscoverAddresses(chainID int64) (postageStamp common.Address, startBlock uint64, found bool)

DiscoverAddresses returns the canonical contracts for this chainID

func New

func New(
	logger logging.Logger,
	ev BlockHeightContractFilterer,
	postageStampAddress common.Address,
	blockTime uint64,
	shutdowner Shutdowner,
) postage.Listener

Types

type BlockHeightContractFilterer

type BlockHeightContractFilterer interface {
	bind.ContractFilterer
	BlockNumber(context.Context) (uint64, error)
}

type Shutdowner

type Shutdowner interface {
	Shutdown(context.Context) error
}

Shutdowner interface is passed to the listener to shutdown the node if we hit error while listening for blockchain events.
