Infura doesn't open this method unfortunately. You will need to run your own node or use something like https://www.quiknode.io/ if you need traces, contracts or tokens with stream

To build a node, do I have to use parity,Why do you need to use the trace_block method to get the token

[kdoda]

@sunysen did you ever find a solution to your issue?

[theweilu]

Is streaming contracts only possible through using a parity node? It seems so by looking at the Traceback.
