Submission Details
Severity:
Unchecked Transfer in claimReward() Could Cause Loss of Reward
Description:
When a staker calls claimReward() to withdraw their reward, it is sent to them with IERC20::transfer function. However, the return value of an external transfer call in claimReward() is not checked.
Impact:
Any transaction to msg.caller that fails will fail silently, which could lead to a loss for the caller.
Tools Used:
Slither
Recommended Mitigation Steps:
Use SafeERC20, or ensure that the transfer return value is checked.
