# Mint | Deposit

To mint **zTokens**, the user must deposit USDC as collateral. 

The user can then select how much **zUSD** they wish to mint. The user can input any value of **zUSD** capped by a minimum collateralization ratio of 150.00%.

### Depositing Collateral

If a user wants to deposit collateral without minting any **zUSD** they can simply leave the mint input box at 0.0 this qualifies a user to receive a share of the fees. Similarly, if they would like to mint **zUSD** without depositing any collateral they can leave the deposit input box at 0.0, provided that the user has sufficient headroom in their collateralization ratio to mint additional **zUSD**
