#### `vote`[](https://docs.kyberswap.com/Legacy/api-abi/core-smart-contracts/api_abi-ikyberdao#vote)
Votes for an option of a campaign, where options are indexed from 1 to N number of options.
***
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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.kyberswap.com/reference/legacy/api-abi/core-smart-contracts/ikyberdao.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
