# What's Hermes?

Hermes - Our keeper program monitors the APY for each lending protocol every 1 hour, and sends rebalance cranks to re-distribute liquidity in the different platforms. There are factors that affect allocation in a platform:

  <Card title="APY" icon="percent" iconType="solid">
    The annual percentage yield offered by each lending protocol.
  </Card>

  <Card title="Total Deposit" icon="building-columns" iconType="solid">
    The total amount of assets currently deposited in the platform.
  </Card>

  <Card title="Deposit Limit" icon="block-brick" iconType="solid">
    The maximum amount of assets that can be deposited into the platform.
  </Card>

  <Card title="Pool Utilization Rates" icon="wave-pulse" iconType="solid">
    The ratio of borrowed assets to total assets in the pool, indicating how much of the pool is being used.
  </Card>

  <Card title="Pool Reserve Levels" icon="piggy-bank" iconType="solid">
    The amount of liquidity available in the pool's reserves.
  </Card>
</CardGroup>

Rebalance cranks are sent every few minutes, so user will get yield just after few minutes depositing in vault
