Time Lock

Time Locks are a smart contract feature that states that some actions will only be performed after a certain period of time rather than immediately. 
There are critical actions that can be used for the good development of the protocol, but the same functions can be performed by malicious individuals with the intention of harming users. Time Lock protects the user from malicious actions and individuals providing time to user protects their funds in case they identify suspicious activities.
All critical contracts in TETU have a 48 hour timelock to provide greater security to users. Very instructive articles on how to check Time Lock Schedule and perform Emergency Withdraw can be read in Guides.
