Functions ¶

func FindSingleEvent ¶

func FindSingleEvent(abi *abi.ABI, receipt *types.Receipt, contractAddress common.Address, event abi.Event, out interface{}) error

FindSingleEvent will find the first event of the given kind.

func IsSynced ¶

func IsSynced(ctx context.Context, backend Backend, maxDelay time.Duration) (bool, error)

IsSynced will check if we are synced with the given blockchain backend. This is true if the current wall clock is after the block time of last block with the given maxDelay as the maximum duration we can be behind the block time.

func NewService ¶

func NewService(logger logging.Logger, backend Backend, signer crypto.Signer, store storage.StateStorer, commonService chain.Common, chainID *big.Int) (chain.Transaction, error)

NewService creates a new transaction service.

func ParseABIUnchecked ¶

func ParseABIUnchecked(json string) abi.ABI

ParseABIUnchecked will parse a valid json abi. Only use this with string constants known to be correct.

func ParseEvent ¶

func ParseEvent(a *abi.ABI, eventName string, c interface{}, e types.Log) error

ParseEvent will parse the specified abi event from the given log

func WaitSynced ¶

func WaitSynced(ctx context.Context, backend Backend, maxDelay time.Duration) error

WaitSynced will wait until we are synced with the given blockchain backend, with the given maxDelay duration as the maximum time we can be behind the last block.

Types ¶

type Backend ¶

type Backend interface {
	bind.ContractBackend
	TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
	TransactionByHash(ctx context.Context, hash common.Hash) (tx *types.Transaction, isPending bool, err error)
	BlockNumber(ctx context.Context) (uint64, error)
	HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
	BalanceAt(ctx context.Context, address common.Address, block *big.Int) (*big.Int, error)
}

Backend is the minimum of blockchain backend functions we need.
