## When will I receive my Hidden Hand rewards? 

Once a protocol's voting epoch concludes, rewards, also known as bribes, are typically distributed within a day to all active participants. This delay is due to a built-in security feature—a three-hour time lock on the rewards distributor. If you've opted to use the Yield Harvester, there's an *additional* three-hour time lock, totaling to at least six hours before you receive your rewards.

## Can I use a contract wallet on Hidden Hand? 

Yes! However, it's important that you set reward forwarding in order to prevent any issues. Please refer to [Reward Forwarding](https://learn.hiddenhand.finance/reward-forwarding) for a tutorial.

## What is the 'efficiency' metric?

Efficiency is a metric for those who deposit incentives for gauges. It represents the rewards distributed to the gauge per $1 of incentives.
