eth_newFilter

Creates a filter for logs matching the specified criteria and returns a filter ID. The filter ID is used with eth_getFilterLogs and eth_uninstallFilter. > 🚧 Response taking too long? Response time may increase with block range! > > Specifying a wide block range or including blocks with many events can cause response delays or timeouts. > > For faster responses: > > - Keep the fromBlock ~ toBlock range to 1000 blocks or less. > - When using blockTag "latest", the response may be slower since the exact block number is not known internally. In that case, use eth_blockNumber to get the latest block number and specify it explicitly.
