Off-chain keepers are automated bots or services that monitor specific conditions in decentralized finance protocols and execute transactions when those conditions are met. These keepers perform critical maintenance tasks, such as initiating liquidations, updating price feeds, or rebalancing collateral pools. By operating off-chain, they reduce the computational burden on the main blockchain and ensure timely execution of time-sensitive operations. This automation is essential for maintaining the stability and functionality of complex derivatives protocols.
Mechanism
The mechanism of off-chain keepers involves a decentralized network of actors competing to execute transactions for a fee. When a condition for execution is met, such as a position becoming undercollateralized, multiple keepers may attempt to submit the required transaction. The protocol’s design must incentivize efficient execution by rewarding the first successful keeper while preventing redundant or malicious actions. This competition ensures that critical functions are performed reliably without relying on a single centralized entity.
Execution
The execution performed by off-chain keepers is vital for managing risk in derivatives markets. For example, in a lending protocol, keepers execute liquidations to ensure that undercollateralized loans are closed before the collateral value drops below the loan amount. The speed and reliability of this execution directly impact the solvency of the protocol. The design of the keeper network must account for potential network congestion and MEV to ensure timely and fair execution.
