eth_getFilterChanges - Poll filter for changes

Polling method for a filter, which returns an array of events that have occurred since the last poll on the Neuroweb network.

Implementation Example

Notes

• This method only returns changes that occurred since the last poll
• Filters timeout if not accessed within a certain time period (typically 5 minutes)
• The first call to eth_getFilterChanges returns all events since filter creation
• Subsequent calls return only new events since the previous call
• Use eth_getFilterLogs to retrieve all accumulated logs regardless of polling
