class (ABIEncoding a) <= EventFilter a  where

Members

• eventFilter :: Proxy a -> Address -> Filter

  Event filter structure used by low-level subscription methods

event :: forall a e p. IsAsyncProvider p => EventFilter a => Address -> (a -> ReaderT Change (Web3 p e) EventAction) -> Web3 p e (Fiber (eth :: ETH | e) Unit)

Start listening to events eminating from the given address and caught by the filter, using the handler to process the data and decide whether to continue

class (ABIEncoding a) <= Method a  where

Class paramaterized by values which are ABIEncodable, allowing the templating of of a transaction with this value as the payload.

Members

• sendTx :: forall u e p. IsAsyncProvider p => EtherUnit u => Maybe Address -> Address -> u -> a -> Web3 p e HexString

  Send a transaction for given contract 'Address', value and input data

• call :: forall b e p. IsAsyncProvider p => ABIEncoding b => Address -> Maybe Address -> CallMode -> a -> Web3 p e b

  Constant call given contract 'Address' in mode and given input data
