# Fees

**Platform fees**

**0.1 % security fee on withdrawals (old vaults only)** which is reinvested in the strategy. This is done to prevent certain attacking techniques, including [sandwich attacks and other vault share manipulation vulnerabilities](https://medium.com/coinmonks/demystify-the-dark-forest-on-ethereum-sandwich-attacks-5a3aec9fa33e)

**0.45 % bounty fee -**  taken from the users' profit and sent to the user who calls the "reinvest function" (check the Bounty section) or the script automating it

**4.05 % performance fee -** taken from the profit users earn by using our platform and sent to our treasury contract

**Deposit fees**

Each pool could have a different deposit fee. Indeed, that one doesn't depend on Matrix, but instead, it depends by the farm provider (i.e., Spookyswap).
