| `setup` is invoked once, in the beginning when the tracer is being constructed by Geth for a given transaction. It takes in one argument `config`. `config` allows users to pass in options to the tracer. `config` is to be JSON-decoded for usage and its default value is `"{}"`. |

@s1na Can you please explain what these new config options are?
There was a problem hiding this comment.
These configs are meant to be tracer-specific. I.e. each JS or native tracer can now define which options it accepts. Let's say the callTracer has the following option to only collect data about the top-level call:
debug.traceTransaction('<txhash>, { tracer: 'callTracer', tracerConfig: { onlyTopCall: true } })
Or we're contemplating adding the following option to the prestateTracer to also collect the state of each account after tx execution:
debug.traceTransaction('<txhash>, { tracer: 'prestateTracer': tracerConfig: { collectPostState: true } })
But passing collectPostState to callTracer will have no effect because callTracer doesn't parse/understand it.
