Locking certain tokens

Question

I have a smart contract, and I would like to send tokens to my holders, however I would like to put a time lock on these tokens, as the holder to keep them for 2 months in their wallet, before they will be able to swap, send or even sell them.

Is there any function to do this ?

1. Any tokens coming from this wallet address, 2)To be locked for this time, 3)before they are unlocked)

Any one can advise me please?

Regards

You could use a vested dapp website, add modifier, or write a function. uint256 numbers are initialized to zero so the following code should work:

mapping(address => uint256) lockedAddress;
uint256 launch = block.timestamp;

modifier isLocked() {
     require(lockedAddress[msg.sender] < block.timestamp + 5184000);
}
