### Fee Structure

**0.1% withdrawal fee:** stays in the vault as a reward to active farmers. This is done to prevent certain vectors of attack, including [sandwich attacks and other vault share manipulation vulnerabilities](https://medium.com/coinmonks/demystify-the-dark-forest-on-ethereum-sandwich-attacks-5a3aec9fa33e).

**4.05% Performance Fee: -** Taken only from the vaults' earned profits

**0.45% gas fee -** Taken from profits earned by the vault in order to help the harvest bot pay for gas costs of harvesting.
