Parameters

Object - The filter options:

fromBlock: QUANTITY|TAG - (optional, default: "latest") Value:
- Integer block number
- "latest" for the last mined block
- "pending", "earliest" for not yet mined transactions.
toBlock: QUANTITY|TAG - (optional, default: "latest") Value:
- Integer block number
- "latest" for the last mined block
- "pending", "earliest" for not yet mined transactions.
address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.
topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics.
- Topics are order-dependent. Each topic can also be an array of DATA with "or" options.
- Check out more details on how to format topics in eth_newFilter.
blockHash: DATA, 32 Bytes - (optional) With the addition of EIP-234 (Geth >= v1.8.13 or Parity >= v2.1.0), blockHash is a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in the filter criteria, then neither fromBlock nor toBlock are allowed.

Returns

Array - 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. ["0x3454645634534..."].
For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].
For filters created with eth_newFilter logs are objects with following params:
- removed: TAG - True when the log was removed, due to a chain reorganization. False if its a valid log.
- logIndex: QUANTITY - Integer of the log index position in the block. Null when its pending log.
- transactionIndex: QUANTITY - Integer of the transactions index position log was created from. Null when its pending log.
- transactionHash: DATA, 32 Bytes - Hash of the transactions this log was created from. Null when its pending log.
- blockHash: DATA, 32 Bytes - Hash of the block where this log was in. Null when its pending. Null when its pending log.
- blockNumber: QUANTITY - The block number where this log was in. Null when its pending. Null when its pending log.
- address: DATA, 20 Bytes - Address from which this log originated.
- data: DATA - Contains one or more 32 Bytes non-indexed arguments of the log.
- topics: Array of DATA - Array of 0 to 4 32 Bytes DATA of indexed log arguments.
  - In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declare the event with the anonymous specifier.
