Syscall Heartbeat serves as an autonomous "pulse" for the blockchain, solving the fundamental limitation that smart contracts are passive and cannot execute themselves. By default, contracts lie dormant until a user interacts with them; this stack "gives them life" by enabling fully automated, recurring execution.
Users simply deploy a Job specifying a target contract, a function signature, and a time interval (e.g., every 60 seconds), funded with a gas deposit. The off-chain Relayer then acts as a reliable clock, monitoring the network and triggering the logic exactly when scheduled. This transforms static code into dynamic, self-sustaining agents capable of performing maintenance, updating oracle prices, or managing game loops without any manual human intervention.
