No Event Emit on Snow::earnSnow

Description

  • The Snow::earnSnow function does not emit any events.

function earnSnow() external canFarmSnow {
if (s_earnTimer != 0 && block.timestamp < (s_earnTimer + 1 weeks)) {
revert S__Timer();
}
_mint(msg.sender, 1);
s_earnTimer = block.timestamp;
​
@> not emit the event
}

Risk

Impact:

  • No event is emitted, making it difficult to track the rewards.

Proof of Concept

​

Recommended Mitigation

Emit an event when the reward is claimed to track the progress of the protocol.

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