# eth\_getLogs (BSC)

**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.**

```javascript
params: [
  {
    "address": "0x0000000000000000000000000000000000001000",
    "topics": [
      "0x627059660ea01c4733a328effb2294d2f86905bf806da763a89cee254de8bee5"
    ],
    "blockHash": "0xcacbb341933a9ad7a62b2024a6bbc69c74152363262b159fb0ef77b28effdc8b"
  }
]
```

**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.
