Parameters

OBJECT - The filter options:

Object Name	Required	Type	Detail
`fromBlock`	❌	String	A hex code of an integer that represents the block number, or "latest" that represents the last mined block.
`toBlock`	❌	String	A hex code of an integer that represents the integer block number, or "latest" that represents the last mined block.
`address`	❌	String/Array	Contract address or a list of addresses from which logs should originate.
`topics`	❌	Array	Array of 32 Bytes `DATA` topics. Topics are order-dependent. Each topic can also be an array of `DATA` with "or" options.
`blockHash`	❌	String	Restricts the logs returned to the single block with the `blockHash`. If `blockHash` is present in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.

Result

It is an array of log objects, or an empty array if nothing has changed since last poll.

For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x123456789..."].
For filters created with eth_newFilter logs are objects with the following fields.

Result Fields

Key	Type	Detail
`address`	String	Address from which this log originated.
`blockHash`	String	Hash of the block where this log was in. `null` if either the returned block is pending or the log is pending.
`blockNumber`	String	A hex code of an integer that represents the block number where this log was in. `null` if either the returned block is pending or the log is pending.
`data`	String	Contains one or more 32 Bytes non-indexed arguments of the log.
`logIndex`	String	A hex code of an integer that represents the log index position in the block. `null` if the log is pending.
`removed`	Boolean	`true` if the log was removed, due to a chain reorganization. `false` if the log is valid.
`topics`	Array	Array of 0 to 4 32 Bytes `DATA` of indexed log arguments.
`transactionHash`	String	Hash of the transactions this log was created from. `null` if the log is pending.
`transactionIndex`	String	A hex code of an integer that represents the transactions index position log was created from. `null` if the log is pending.
