 This contract acts as an escrow that locks and holds an owner's tokens for a lockup period.

 A lockup period starts from the specified timestamp and lasts for the specified duration.
 Tokens will be unlocked linearly.
 
 Vesting is an additional mechanism. It also locks the tokens, and it allows to configure 2 more options:
+
 1. Ability to terminate tokens vesting and refund non-vested tokens back.
 2. Cliff vesting period.
 
 The owner can add a full access key to the account if all conditions are met:

 - The termination process is ended (if applicable). If there’s a termination process started, it has to finish;

 ### Guarantees
 
 With the guarantees from the staking pool contracts, whitelist, and voting contract, the lockup contract provides the following guarantees:
+
 - The owner can not lose tokens or block contract operations by using methods under the staking section.
 - The owner can not prevent the foundation from withdrawing the unvested balance in case of termination.
 - The owner can not withdraw tokens locked due to lockup period, disabled transfers, or vesting schedule.
