StakeHolder Contract

The StakeHolder contract serves as a secure holding space, acting as an intermediary or escrow for the Ethereum (ETH) staked by individual users. Here's an overview of its functions:

Functions

1. Constructor:

   This function sets up the StakeHolder contract with essential initializations. It requires the addresses of the staker and the master contract (presumably the contract managing the staking system) and initial ETH value sent along with the deployment transaction. It emits a DepositReceived event indicating the initial deposit.

constructor(address _staker, address _masterContract) payable {
       require(msg.value > 0, "Must send ETH to create a stake");
       staker = _staker;
       masterContract = _masterContract;
       emit DepositReceived(_staker, msg.value);
   }

2. releaseFunds(uint256 amount):

This function releases a specified amount of ETH to the staker. It can only be called by the masterContract, ensuring controlled access. The contract verifies the available balance and transfers the specified amount of ETH to the staker, emitting a FundsReleased event upon successful release.

//Function to release funds to the staker
   function releaseFunds(uint256 amount) external {
       require(msg.sender == masterContract, "Only the master contract can release funds");
       require(amount <= address(this).balance, "Insufficient balance to release");
       payable(staker).transfer(amount);
       emit FundsReleased(staker, amount);
   }

3. deposit():

This function allows the staker to add more ETH to the StakeHolder contract. Only the staker can call this function, and any ETH sent along with the transaction increases the staked amount. It emits a DepositReceived event, acknowledging the additional deposit made by the staker.

// Function to allow the staker to add more funds to the StakeHolder
   function deposit() external payable {
       require(msg.sender == staker, "Only the staker can deposit more funds");
       emit DepositReceived(msg.sender, msg.value);
   }

4. receive() external payable:

This function acts as a fallback to accept ETH sent directly to the contract. It ensures that the contract can receive ETH and emits a DepositReceived event for any incoming ETH transactions.

// Ensure that the contract can receive ETH
   receive() external payable {
       emit DepositReceived(msg.sender, msg.value);
   }
