Unveiling the StakingRewards Contract on BTTC 🚀
As a crypto enthusiast, you have a unique opportunity to leverage the StakingRewards contract on the BitTorrent Chain (BTTC). This contract is designed to empower users by allowing token staking and earning rewards, ensuring a user-friendly and automated process that motivates ongoing involvement.
Exploring the StakingRewards Contract: A Roadmap to Passive Earnings 🏦
The StakingRewards contract provides a framework where users can stake their tokens for rewards within a defined timeframe. This smart contract is tailored to create mechanisms that encourage long-term engagement within the BTTC ecosystem, offering a chance for passive income through participation.
Core Components: Underpinning Structures and Variables 🛠️
At the heart of the StakingRewards contract lie crucial state variables that dictate the staking and rewards process. Below are some key elements that lay the groundwork for the functionality:
IERC20 public immutable stakingToken; IERC20 public immutable rewardsToken; address public owner; uint public duration; // Rewards distribution duration (in seconds) uint public finishAt; // Timestamp when rewards conclude uint public updatedAt; // Latest reward update time uint public rewardRate; // Reward payout per second uint public rewardPerTokenStored; // Accumulated rewards per token mapping(address => uint) public userRewardPerTokenPaid; // User's reward contributions mapping(address => uint) public rewards; // Pending rewards for users uint public totalSupply; // Total amount staked mapping(address => uint) public balanceOf; // User’s stake balance
These variables form the backbone of the contract, shaping how staking and reward mechanisms operate.
Notifications and Transparency: Keeping Participants Updated 📢
Incorporating events into the contract fosters transparency and makes off-chain tracking easier. Here’s a look at suggested events:
event Staked(address indexed user, uint amount); event Withdrawn(address indexed user, uint amount); event RewardPaid(address indexed user, uint reward); event RewardDurationUpdated(uint newDuration); event RewardNotified(uint amount);
Main Functions: Powering Staking and Reward Distribution 🔑
Constructor Function
constructor(address _stakingToken, address _rewardToken) {
owner = msg.sender;
stakingToken = IERC20(_stakingToken);
rewardsToken = IERC20(_rewardToken);
}
This constructor initializes the contract by defining the staking and rewards token addresses, assigning the deployer as the owner.
Control Modifiers
modifier onlyOwner() {
require(msg.sender == owner, "not authorized");
_;
}
modifier updateReward(address _account) {
rewardPerTokenStored = rewardPerToken();
updatedAt = lastTimeRewardApplicable();
if (_account != address(0)) {
rewards[_account] = earned(_account);
userRewardPerTokenPaid[_account] = rewardPerTokenStored;
}
_;
}
These modifiers ensure that only the contract owner can execute certain critical functions and help maintain accurate reward states prior to any changes.
Reward Calculation Mechanisms
function lastTimeRewardApplicable() public view returns (uint) {
return _min(finishAt, block.timestamp);
}
function rewardPerToken() public view returns (uint) {
if (totalSupply == 0) {
return rewardPerTokenStored;
}
return rewardPerTokenStored +
(rewardRate * (lastTimeRewardApplicable() - updatedAt) * 1e18) /
totalSupply;
}
These functions are essential for determining the timing of reward accruals and computing the reward rate for each token.
Staking and Withdrawing Tokens Made Easy 💰
function stake(uint _amount) external updateReward(msg.sender) {
require(_amount > 0, "amount = 0");
stakingToken.transferFrom(msg.sender, address(this), _amount);
balanceOf[msg.sender] += _amount;
totalSupply += _amount;
emit Staked(msg.sender, _amount);
}
function withdraw(uint _amount) external updateReward(msg.sender) {
require(_amount > 0, "amount = 0");
balanceOf[msg.sender] -= _amount;
totalSupply -= _amount;
stakingToken.transfer(msg.sender, _amount);
emit Withdrawn(msg.sender, _amount);
}
These functions enable users to effectively stake and withdraw their tokens while automatically updating associated rewards.
Claiming Rewards 🏆
function earned(address _account) public view returns (uint) {
return (balanceOf[_account] * (rewardPerToken() - userRewardPerTokenPaid[_account]) / 1e18) +
rewards[_account];
}
function getReward() external updateReward(msg.sender) {
uint reward = rewards[msg.sender];
if (reward > 0) {
rewards[msg.sender] = 0;
rewardsToken.transfer(msg.sender, reward);
emit RewardPaid(msg.sender, reward);
}
}
These methods calculate a user’s rewards and facilitate the claiming of these amounts.
Setting Reward Frameworks 🗓️
function setRewardsDuration(uint _duration) external onlyOwner {
require(finishAt > block.timestamp, "reward period ongoing");
duration = _duration;
emit RewardDurationUpdated(_duration);
}
function notifyRewardAmount(uint _amount) external onlyOwner updateReward(address(0)) {
if (block.timestamp >= finishAt) {
rewardRate = _amount / duration;
} else {
uint remainingRewards = (finishAt - block.timestamp) * rewardRate;
rewardRate = (_amount + remainingRewards) / duration;
}
require(rewardRate > 0, "reward rate = 0");
require(rewardRate * duration <= _amount, "reward amount > balance");
finishAt = block.timestamp + duration;
updatedAt = block.timestamp;
emit RewardNotified(_amount);
}
These functionalities empower the owner to define the reward duration and inform the contract of the available reward allocation.
Utility Functions 🤖
function _min(uint x, uint y) private pure returns (uint) {
return x < y ? x : y;
}
