Description

  • best to do block.timestamp <= time instead of block.timestamp <= time

  • if user call spot on time , tranzact will be revert

function earnSnow() external canFarmSnow {
i@> f (s_earnTimer != 0 && block.timestamp < (s_earnTimer + 1 weeks)) {
revert S__Timer();
}
_mint(msg.sender, 1);
​
s_earnTimer = block.timestamp;
}

Risk

Likelihood:

  • if user call spot on time anf s_EarnTimer != 0 , tranzact will be revert

Proof of Concept

Recommended Mitigation

- if (s_earnTimer != 0 && block.timestamp < (s_earnTimer + 1 weeks)) {
revert S__Timer();
}
+ if (s_earnTimer != 0 && block.timestamp <= (s_earnTimer + 1 weeks)) {
revert S__Timer();
}
