The stability and security of the Primex protocol rely on the timely liquidation of risky positions to protect the funds of Lenders. The closing swap must cover the borrowed assets plus fees to achieve this.

However, initiating a liquidation or conditional order in a smart contract must be done through a transaction requiring external actors. Keepers are nodes responsible for executing these actions in Primex on behalf of the protocol. They are incentivized with fees to cover gas costs and ensure efficient execution.

Keepers use special software to monitor the blockchain and send transactions, while all necessary information to check liquidation conditions is stored on-chain, eliminating the need for trust.

Keepers perform Liquidation, Limit orders, and Take Profit / Stop Loss orders.
