# Claiming Miner Rewards

Miners and mining pools are awarded EGL's when they produce a block with a gas limit that is within 1,000,000 of the `desiredEgl`. The reward amount is based on how close the block gas limit is to the `desiredEgl` value. 

See [Mining Pool Reward](https://docs.egl.vote/protocol-overview/miner-rewards) for details

The reward must claimed by calling the `sweepPoolRewards()` and rewards for the block it is included in. The function can be called by anyone but the reward always goes to the `block.coinbase` address so the intention is for miners to include this transaction when they produce the block

### 1.`sweepPoolRewards()`

#### Function Signature

```javascript
function sweepPoolRewards() external whenNotPaused
```

#### Web3 Example

```javascript
await eglVotingInstance.sweepPoolRewards({ from: "0x2be650ba..."})
```

#### Python Example

This example shows how to create, sign and send the raw transaction which calls `sweepPoolRewards()`

```python
import sys
from web3 import Web3

if __name__ == "__main__":
    chainId = int(sys.argv[1])
    eglContractAddress = sys.argv[2]
    accountPvtKey = sys.argv[3]
    accountNonce = int(sys.argv[4])

    w3 = Web3(Web3.HTTPProvider())
    transaction = {
        "to": eglContractAddress, 
        "value": 0, 
        "gas": 78000, 
        "gasPrice": int(10*1e9), 
        "nonce": accountNonce, 
        "chainId": chainId, 
        "data": "0x112bbd1d"
    }
    signed_tx = w3.eth.account.sign_transaction(transaction, accountPvtKey)
    print(signed_tx.rawTransaction.hex())
    w3.eth.send_raw_transaction(signed_tx.rawTransaction)
