# No migrator code

The PancakeSwap Masterchef contract, for all its advantages, has a critical vulnerability - the so-called Migrator code, which allows the contract owner to withdraw the funds blocked in it at his discretion. As a result of the fact that most of the PancakeSwap forks retained the Migrator code, dozens of projects created by outright scammers just to steal farmers' funds appeared on the market.<br>

The GREENBEAN Masterchef contract does not have this vulnerability - the Migrator code is completely removed from it, so that no one can steal user funds.

You see the following code still present in the following link :

```
Migrate lp token to another lp contract. Can be called by anyone. We trust that migrator contract is good.
    function migrate(uint256 _pid) public {
        require(address(migrator) != address(0), "migrate: no migrator");
        PoolInfo storage pool = poolInfo[_pid];
        IBEP20 lpToken = pool.lpToken;
        uint256 bal = lpToken.balanceOf(address(this));
        lpToken.safeApprove(address(migrator), bal);
        IBEP20 newLpToken = migrator.migrate(lpToken);
        require(bal == newLpToken.balanceOf(address(this)), "migrate: bad");
        pool.lpToken = newLpToken;
```
