eth_getLogs

Returns an array of all logs matching a given filter object.
Parameters
Object - The filter options:
fromBlock: QUANTITY|TAG - (optional, default: "latest") Value:
Integer block number
"latest" for the last mined block
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.
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.
params: [
  {
    "address": "0xb59f67a8bff5d8cd03f6ac17265c550ed8f33907",
    "topics": [

  }
]
Returns
Array - Array of log objects, or an empty array if nothing has changed since last poll.
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.
