Used to adjust reward calculation
uint256 public lastUpdatedBlock
This is the number of last block in which function update() is called
uint256 public rewardPerBlock
Used to adjust staking APY
uint256 public scale
Used for math calculations
uint256 public particleCollector
When users call claim(),sum of daoShare and earlyFoundersShare is added to this variable
uint256 public daoShare
Denotes the share of DAO
uint256 public earlyFoundersShare
Denotes the share of early founders
address public daoWallet
Denotes the wallet of DAO
address public earlyFoundersWallet
Denotes the wallet of early founders

Struct
User {uint256 depositAmount; uint256 paidReward;}
Modifier
onlyTrusty()
Restricts actions to the trusty wallet( DAO agent/multisig wallet), e.g. set variables
View Function
pendingReward(address _user) external view returns (uint256 reward)
Returns the amount of reward which user can claim until the current block
Public Functions
update() public
Updates reward variables of the pool to be up-to-date. It is called when someone deposit or withdraw his/her LP tokens
deposit(uint256 amount) external
Called when user wants to stake his/her LP tokens
depositFor(address _user, uint256 amount) public
Called when user wants to stake his/her LP tokens for a specific address
withdraw(uint256 amount) external
It is called for two purposes: 1. Claiming reward (if amount = 0) 2. Withdrawing LP tokens + Claiming reward (if amount > 0)
withdrawParticleCollector() public
Transfers daoShare and earlyFoundersShare to daoWallet and earlyFoundersWallet. It can be called by anyone
emergencyWithdraw() external
Withdraws LP tokens without caring about rewards. EMERGENCY ONLY
Restricted functions
withdrawAllStakedtokens(address to) external onlyTrusty
Add temporary withdrawal functionality for owner(DAO) to transfer all tokens to a safe place.
setStakedToken(address _stakedToken) external onlyTrusty
Sets stakedToken address
setWallets(address _daoWallet, address _earlyFoundersWallet) external onlyTrusty
Sets daoWallet and earlyFoundersWallet
setShares(uint256 _daoShare, uint256 _earlyFoundersShare) external onlyTrusty
Sets daoShare and earlyFoundersWallet
setRewardPerBlock(uint256 _rewardPerBlock) external
Sets rewardPerBlock
