Missing SnowEarned event emission in earnSnow
Description: The earnSnow function mints a token but does not emit the corresponding SnowEarned event, making it difficult to track on-chain free token claims.
Impact: The absence of event emission for free token claims creates an inconsistency in the contract's event logging pattern, as purchases emit events but free claims do not. This makes it difficult for off-chain systems to track token distribution comprehensively and complicates user activity monitoring.
Recommended Mitigation:
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);
}
