## Heartbeat Update Mechanisms

Heartbeat update mechanisms are a protocol feature that forces an oracle to update its price feed at regular intervals, regardless of market volatility. This ensures that the smart contract always has access to a relatively fresh price, even if the market is quiet.

If a price does not move significantly, the heartbeat ensures that the system does not rely on a stale price for too long. It acts as a safety net against the risks of outdated information.

This is particularly important for lending protocols that need to check collateral values periodically. The heartbeat interval is a tunable parameter that balances the cost of updates against the need for data freshness.

It is a simple but effective way to improve the reliability of oracle feeds. When combined with volatility-based updates, it creates a robust data management strategy.

It is a standard component of modern oracle architectures.
