Parameters:

• uint256 _pid: pool id

• bool _withStake: withdraw the amount with or without the stake.

function viewEligibleAmount(uint256, address)

This function is basically used to view the eligible amount which needs to be withdrawn if the user deposits the amount in multiple vaults.

Parameters:

• uint256 _pid: pool id

• address _user: user address

function updateBlockReward(uint256, address)

This function is used to calculate the total block reward as defined ASTRADAO per block and the distribution will be calculated with the current user reward multiplier, total user multiplier, and total pool multiplier. After calling this function users can update their reward.

Parameters:

• uint256 _pid: pool id

• address _sender: user address

function viewRewardInfo(uint256, address)

This function is used to view the total reward (including block reward) which the user has earned on the Astra DAO platform.

Parameters:

• uint256 _pid: pool id

• address _userAddress: User address

function withdrawASTRReward(uint256 _pid, bool _withStake)

This function is used to claim the ASTRADAO rewards. Users can claim the claimable ASTRADAO reward. There are two options for claiming the reward with or without staking the Astra DAO token. If the user wants to claim 100% then he needs to stake the ASTRADAO to Astra DAO pool. Otherwise, a percentage of ASTRADAO amount would be deducted as a fee.

Parameters:

• uint256 _pid: pool id

• bool_withStake: with or without stake
