# MasterChef V1

Scads MasterChef v1 is a main staking contract for Farms while providing more flexibility for adjusting the $SCADS emissions, including Scads pool, burn and other Scads products.

### Do I need to migrate?

If you are currently using old Scads MasterChef, you will need to migrate to the new contract ([0x97B631AcBAC4C38Bb0AA18691ea60dB2754609FB](https://testnet.bscscan.com/address/0x97B631AcBAC4C38Bb0AA18691ea60dB2754609FB)).

### Overview

#### Deposit 

If you are currently using the `enterStaking(uint256 _amount)` on the current Scads MasterChef. You need to migrate to the new Scads pool contract. Check out the related documentation [here](broken://pages/gMY0Hvj1atvvNTz0SSG4).

The deposit function for the farm pools is unchanged. However, you will need to upgrade the MasterChef address and the `pid` , check out the [list of farms](broken://pages/3Nb9bGvxzNMVCjFBOZjP) for the list of new `pids` on MasterChef v1.

#### Staking Balance

Use `userInfo[_pid][_user].amount` to query the staking balance.

#### Staking Token 

Note that the new `PoolInfo` struct **does not** contain the lp token address field, you will need to use `lpToken(_pid)` to query any given pool's staking token. 

#### Total Staking Shares/Amount

Use `lpToken.balanceOf(MasterChef.address)` to get the total staking amount for any given farm pool.

#### Multiple Rewards Update

Use massUpdatePools() to detect and distribute pending multiple rewards to the users.

You can check more details of multiple rewards distribution in [Farms](/zoinkswap/products/farms.md) & [Pools](/zoinkswap/products/pools.md).
