# Other concepts

Brila infrastructure enables lenders, borrowers, and portfolio managers to deploy capital via lending pools and loans.

Portfolio managers on Brila deploy lending pools (or `vaults`) which in turn can deploy capital to borrowers via loans (`instruments`).

The following smart contracts represent vaults and instruments within the Brila protocol:
