# Migrator Code Removed

From the original SushiSwap fork, the migrator function has been a staple of many forks, including PancakeSwap ([https://github.com/pancakeswap/pancake-farm/blob/a61313bf107c7f82e1a0f5736d815041fbf8cdff/contracts/MasterChef.sol#L170 ](<https://github.com/pancakeswap/pancake-farm/blob/a61313bf107c7f82e1a0f5736d815041fbf8cdff/contracts/MasterChef.sol#L170 >))

Let's be clear, a migrator code is not good or bad per se, it has it's uses that are not necessarily nefarious.

Our own contract does NOT have a Migrator function, which can be checked here: (<https://github.com/BullRunFinance/contracts/blob/main/contracts/BullMasterchef.sol>)
