Submission Details
Severity:
Useless `addReward` function
Summary
This function is supposed to add rewards to rewardPoolarray and it does it perfectly.
function addReward(string memory _name, uint256 _value) public {
require(msg.sender == owner, "Only owner can add rewards");
rewardPool.push(Reward(_name, _value));
}
But players will never have a chance to get this rewards as openBoxfunction has hardcoded rewards and its algorithm does not add new rewards.
if (randomValue < 75) {
// 75% chance to get Coal (0-74)
rewardsOwned[msg.sender].push(Reward("Coal", 0 ether));
} else if (randomValue < 95) {
// 20% chance to get Bronze Coin (75-94)
rewardsOwned[msg.sender].push(Reward("Bronze Coin", 0.1 ether));
} else if (randomValue < 99) {
// 4% chance to get Silver Coin (95-98)
rewardsOwned[msg.sender].push(Reward("Silver Coin", 0.5 ether));
} else {
// 1% chance to get Gold Coin (99)
rewardsOwned[msg.sender].push(Reward("Gold Coin", 1 ether));
Impact
Broken contract logic.
Recommendations
