arguments:

contract parameter can be one of:

  • keyword :some-contract
  • tuple of keyword and address [:some-contract 0x1234...]

returns:

function returns a Promise resolving to a transaction-hash (state-altering calls) or method return value (read-only calls).

This function installs event filter

arguments:

contract parameter can be one of:

  • keyword :some-contract
  • tuple of keyword and address [:some-contract 0x1234...]
  • instance SomeContract

event : camel_case keyword corresponding to the smart-contract event

filter-opts : a map of indexed return values you want to filter the logs by e.g. {:valueA 1 :valueB 2}

opts : specifies additional filter options, can be one of:

  • string 'latest' to specify that only new observed events should be processed
  • map {:from-block 0 :to-block 100} specifying earliest and latest block on which the event handler should fire

on-event : event handler function
