# Asset Parameters

Each asset within zkLend is evaluated based on their risk, which influences how they are supplied and borrowed within the protocol. Once Governance has been setup, assets will be added or removed through a governance proposal or via Asset listing admins selected by zkLend Governance.

### For Borrow/Lend

### Caps

Borrow caps are implemented at the pool level, which means that once the aggregate limit has been reached, users will not be able to borrow that asset until either repayments are made.
