# ⏳Timelock

What is **Timelock?**

* Timelocks prevent any unseen and immediate changes to the PolyFund smart contracts. Changes are locked for a period of time and can be monitored publicly, alerting users to any changes.
* Without timelocks, malicious parties can modify smart contracts immediately, giving no warning to the users.

**Timelock has been added to the MasterChef contract before launch. Our timelock delay is at 24h.**
