# Mint

To mint ***zTokens***, the user must deposit Celo USD (***cUSD***) 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%. 

If a user wants to deposit collateral without minting any ***zUSD*** they can simply leave the mint input box at 0.0. 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**.*
