secure implementation for handling token claims with merkle proofs and legal signature acknowledgement
The example contract verifies user balances through a farming contract interface before processing claims. (that got stuck)
interface IYourFarm {
function userInfo(uint256 _pid, address _user)
external
view
returns (uint256 amount, uint256 rewardDebt);
}
//update these to interface your external contract
IYourFarm public constant YOUR_FARM = IYourFarm(address);
uint256 public constant POOL_ID = yourPoolId;
function getStakedBalance(address _user) public view returns (uint256) {
//implement your balance check logic
return userBalance;
}
