# eth\_getLogs

Returns an array of all logs matching a given filter object.

This method will use `80` [Compute Units](../../about/billing).

***

## Reference: [Here](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getlogs)

## **Parameters**

1. `Object` - The filter options:

* `fromBlock`: `QUANTITY|TAG` - (optional, default: `"latest"`) Integer block number, or `"latest"` for the last mined block or `"pending"`, `"earliest"` for not yet mined transactions.
* `toBlock`: `QUANTITY|TAG` - (optional, default: `"latest"`) Integer block number, or `"latest"` for the last mined block or `"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.
* `blockhash`: `DATA`, 32 Bytes - (optional, **future**) With the addition of EIP-234, `blockHash` will be 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 in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.

```bash
params: [
  {
    topics: [
      "0x000000000000000000000000a94f5374fce5edbc8e2a8697c15331677e6ebf0b",
    ],
  },
]
```

## Returns

See [eth\_getFilterChanges:](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getfilterchanges)

`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 declared the event with the `anonymous` specifier.)
