  • 1 notes.

No critical security issues were found.

2.1 High Gas spending

Severity: note.


The function massUpdatePools() updates every existing pool. It will use many gas if will be many pools.
This function is calling from others functions: add()set() (it’s possible not update pools from them), updateRewardPerBlock()setRewardsValue()updateRewardsValue(), so Gas usage will be high i those functions too.

However, using massUpdatePools() in the functions setRewardsValue()updateRewardsValue() is not required and may be removed from them.

3. Conclusion

The audited smart contract can be deployed. The issues pointed in the previous report are fixed.
