SolidityStake v1

SolidityStake is a simple solidity scaffolding library for providing User Staking Data when Staking ERC20 or ETH to a Smart Contract

Features Include

• Staking and Unstaking

• Setting a Minimum Staking Amount

• Setting a Staking Fee

• Owner Unstake all Users

• Owner Contract Renunciation

• Custom Error Messages

• Total Staker Count

• Getting User Staking Amount

• Getting User Lifetime Staking Amount

• Getting User Joindate

• Getting User Staking Percentage

• Builtin User Yield Variables

You can also easily loop through each staker (see UnstakeAll() function)

sETH.sol (For Staking Native ETH/AVAX/BNB/MATIC etc)
sTOKEN.sol (For Staking Tokens)

NOTE: Requires OpenZeppelin Contracts
npm i @openzeppelin/contracts

Implementation Example

contract SolStakeEth is ReentrancyGuard, Ownable {
  ...
  uint256 public fees_collected;
  ...
  function Stake() external nonReentrant payable {
    ...
    uint256 fee = (eth * 1000) / 10000;
    fees_collected = fee;
    LendToAAVEorCURVEetcETC(fee);
    ...
  }
}

contract myContract is SolStakeETH {
  ...
    function FeesCollected() public view returns (uint256){
      return fees_collected;
    }
  ...
}

When calling the contract via ethers.js

await myContract.Stake({ value: ethers.utils.parseEther("1000") });
let total_fees = ethers.utils.formatEther(await myContract.FeesCollected());
let bal = ethers.utils.formatEther(await myContract.GetStakingAmount(staker.address));
console.log(bal); // 900
console.log(total_fees); // 100
