# TectonicCore

The TectonicCore contract is the risk management layer of the Tectonic protocol. It determines how much collateral a user is required to maintain, and whether (and by how much) a user can be liquidated. Each time a user interacts with a tToken, the TectonicCore is asked to approve or deny the transaction.

The TectonicCore maps user balances to prices (via the [Price Oracle](/docs/developer/price-oracle.md)) to risk weights (called [Collateral Factors](/docs/protocol/money-market-parameters.md)) to make its determinations. Users explicitly list which assets they would like included in their risk scoring, by calling `Enter Markets` and `Exit Markets`.\
