eth_newFilter

Creates a filter object, based on filter options, to notify when the state changes (logs). To check if the state has changed, call eth_getFilterChanges.

A note on specifying topic filters:

Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:

[] “anything”

[A] “A in first position (and anything after)”

[null, B] “anything in first position AND B in second position (and anything after)”

[A, B] “A in first position AND B in second position (and anything after)”

[[A, B], [A, B]] “(A OR B) in first position AND (A OR B) in second position (and anything after)”
