Banana Farming 🍌

This repo is home to the Farming contracts for ApeSwap. Liquidity pools are initialized and added as a staking token to the MasterApe contract. This MasterApe contract is also in control of the number of minted $BANANA per block. As users stake LP and other tokens, the MasterApe distributes them according to the weight of rewards of a specific pool along with an accounts stake in that pool.

Updates to MasterApe

As MasterApe is fork of Pancake's MasterChef, we want to be transparent about the updates that have been made: https://www.diffchecker.com/XSrDXXBe

• Migrator Function removed: This function has been used in rug pulls before and as we want to build trust in the community we have decided to remove this. We don't claim to be the first, but we agree with the decision.
• Farm safety checks. When setting allocations for farms, if a pool is added twice it can cause inconsistencies.
• Helper view functions. View functions can only read data from the contract, but not alter anything which means these can not be used for attacks.
• Only one admin. A recent project was exploited that used multiple forms of admins to control the project. An admin function that was not timelocked was used to make the exploit. We want the timelock to have full control over the contract so there are no surprises

Updates BNBRewardApe

BNBRewardApe contract is a spin off of Pankcake's SmartChef contract, but will provide a means to distribute BNB for staking tokens in place of a BEP20 token. The updates may be found here: https://www.diffchecker.com/BWzELIHw

BEP20RewardApe

BEP20RewardApe contract is similar to the BNBRewardApe contract, but it gives out a BEP20 token as the reward in place of BNB. Find the updates from the BNBRewardApe here: https://www.diffchecker.com/IYZFKbNf

BEP20RewardApeV2

BEP20RewardApeV2 adds two admin functions which allow the pool rewards to be updated allowing the pool to be extended for a longer period of time. https://www.diffchecker.com/h96HRT2L

DEX Contracts

• ApeFactory: 0x0841BD0B734E4F5853f0dD8d7Ea041c241fb0Da6 The ApeFactory is the primary DEX contract which is used to create and track all pairs created on the ApeSwap protocol. When a new pair needs to be created, this contract deploys a completely new pair contract specifically for these tokens and notes the address for future lookup.
• ApeRouter: 0xcF0feBd3f17CEf5b47b0cD257aCf6025c5BFf3b7 The ApeRouter is an external, non-value holding, contract which manages different sets of interactions with the ApeFactory related to adding/removing liquidity and swapping tokens. Because this contract holds no value it can be upgraded without needing to redeploy the ApeFactory.

Farm Contracts

• BananaToken: 0x603c7f932ED1fc6575303D8Fb018fDCBb0f39a95 BananaToken represents the native token of the ApeSwap protocol. This token is distributed to farmers who stake tokens which are recognized by ApeSwap's farm.
• MasterApe: 0x5c8D727b265DBAfaba67E050f2f739cAeEB4A6F9 The MasterApe contract represents the main farm contract which is in charge of distributing BANANA to farmers staking on the ApeSwap protocol.
• Timelock: 0x2F07969090a2E9247C761747EA2358E5bB033460 The Timelock acts as the owner of the MasterApe to limit how fast owner functions can be called on the protocol. A transaction must first be queued in this contract which emits an event that users can evaluate. After a set delay, this tx can be executed which updates a setting on the MasterApe. The Timelock is primarily used to manage the farm by adding new staking tokens and updating their reward weight.
• MultiCall: 0x38ce767d81de3940CFa5020B55af1A400ED4F657 The MultiCall contract is a non-value holding contract which is used by the front-end to batch calls to contracts.

Deprecated Contracts

• BananaSplitBar: 0x86Ef5e73EDB2Fea111909Fe35aFcC564572AcC06 The BananaSplitBar is a token contract for the BananaSplit token. The BananaSplit token is deprecated because there is a known vulnerability in the MasterApe contract that allows unlimited BananaSplit tokens to be generated. As such, the BananaSplit token is not acknowledged on the ApeSwap protocol.

• SupportApe: 0x54aff400858Dcac39797a81894D9920f16972D1D The SupportApe contract is meant to be used as a staking contract for BananaSplit tokens. As BananaSplit tokens are not used on the ApeSwap protocol, this contract has been deprecated.
