filter_id
— a single filter identifier as a hexadecimal string. This filter ID is returned by eth_newFilter
or eth_newBlockFilter
and is used to poll for changes to the filter.eth_getFilterChanges
in this page, first create a new filter using one of the following:Then use the fresh filter ID as the parameter for eth_getFilterChanges
.result
— an array of log objects. Each log object contains details about the event, including whether the log was removed (due to a chain reorganization), log index, transaction index, transaction hash, block hash, block number, address that generated the log, data associated with the log, and topics (event signatures and indexed event parameters).eth_getFilterChanges
method is essential for decentralized applications that need to monitor specific events on the blockchain. For example, a dApp might use this method to listen for token transfer events or contract interactions that trigger specific functionalities within the application.Array of log objects since last poll
The response is of type object
.
