# Harvester/Compound Events

How Often Do the Vaults Compound Rewards?

Our harvester bots are hosted in the highly reliable AWS cloud for nearly 100% uptime and operate on a regular schedule. Here's how they work:

**Frequency:** The bots run every 5 minutes, scanning for the profitability of the vault's harvest event.

**Execution:** If the 0.5% harvester dedicated reward fee is greater than the gas cost to compound the pool, the bots will execute. This means the upper bound for harvesting is approximately every 5 minutes but scales on the reward rate and total value of the vault (TVL).

**Harvest on Deposit Events:** We also harvest on every deposit into the vault to protect against any existing user-earned rewards being distributed to new depositors.

**Baseline Harvest Period:** Our baseline harvest period is every 2 hours for vaults that have over $200 TVL, ensuring we do not drop below this frequency. Vaults below this TVL may not be picked up by the bot and may require a longer wait between harvest events. If users do not wish to wait for the next event, there is a manual harvest interaction option on the vault as described below.

## How to Manually Harvest a Vault

**Manual Harvest:** There is a manual harvest button available in the vault info for users who do not want to wait for the next harvest event or would like to trigger a harvest event before they withdraw their tokens.
