Frozen Markets and Reserves

Freezing and Unfreezing Reserves

In the PhoLend protocol, the state of a reserve can be altered to "frozen" through the function setReserveFreeze within the PoolConfigurator contract. This action can only be executed by user who holds the PoolAdmin role. A frozen reserve restricts the addition of new funds and the initiation of new loans, although it still permits the repayment of existing loans, withdrawals of supplied funds, and processing of liquidations.

Unfreezing a reserve reverts it back to its normal operational state, enabling typical activities such as supplying and borrowing, provided that the overarching conditions of the market permit.

Pausing Reserves

A paused reserve represents a state of complete operational lockdown within the protocol. When a reserve is paused, all interactions including supplying, borrowing, repaying loans, liquidating, and transferring tokens are prohibited. The transition to and from this state is managed through the setReservePause function, which, like freezing and unfreezing, is accessible solely to the user with the PoolAdmin role.
