***

function **vote**(uint256 campaignID, uint256 option) external | Parameter | Type | Description | | --------- |:-----:|:-----------:| | `campaignID` | uint256 | ID of campaign | | `option` | uint256 | ID of option |

\
\### \`getLatestNetworkFeeData\` Returns the latest network fee data and expiry timestamp. \_\_\_ function \_\_getLatestNetworkFeeData\_\_() external view returns (uint256 feeInBps, uint256 expiryTimestamp)\ \*\*Returns:\*\*\ feeInBps - network fee in BPS expiryTimestamp - the timestamp when the fee will expire and needs to be updated\
\### \`shouldBurnRewardForEpoch\` Since some epochs have rewards but no one can claim it, return true if those rewards should be burned. \_\_\_ function \_\_shouldBurnRewardForEpoch\_\_(uint256 epoch) external view returns (bool) | Parameter | Type | Description | | --------- |:-----:|:-----------:| | \`epoch\` | uint256 | epoch number to check | \*\*Returns:\*\*\ \`true\` if rewards should be burned for the epoch, \`false\` otherwise\
\### \`getPastEpochRewardPercentageInPrecision\` Returns the staker's reward percentage in precision for a past epoch only. \_\_\_ function \_\_getPastEpochRewardPercentageInPrecision\_\_(address staker, uint256 epoch) external view returns (uint256) | Parameter | Type | Description | | --------- |:-----:|:-----------:| | \`staker\` | address | staker's address | | \`epoch\` | uint256 | past epoch number | \*\*Returns:\*\*\ Past epoch reward percentage in precision for the staker\
\### \`getCurrentEpochRewardPercentageInPrecision\` Returns the staker's reward percentage in precision for the current epoch. Reward percentage is not finalized until the current epoch has ended. \_\_\_ function \_\_getCurrentEpochRewardPercentageInPrecision\_\_(address staker) external view returns (uint256) | Parameter | Type | Description | | --------- |:-----:|:-----------:| | \`staker\` | address | staker's address | \*\*Returns:\*\*\ Current epoch reward percentage in precision for the staker
