This is repo is built on top of the Unipool repo by the user k06a (forked from). The only addition to this repo as of now is the zUnipool.sol
zUnipool contract tokenises the staking of the Uniswap LP tokens into the Unipool contract, deployed on the mainnet by Synthetix. The staking actually happens by using the Unipool contract that is availiable as contracts/Unipool.sol.
As of now the staking of the Uniswap LP tokens does not provide you with an ERC20 token in return, thus, making the entire staking portion non-transferable.
The objective of the zUnipool contract is to provide the user with an ERC20 token which represents this staking and appreciates in value considering the SNX rewards that are accrued on account of staking.
This contract has been in internal development and testing for over 2 weeks (at the time of this writing 6 March 2020). Various aspects of this contract has been tested multiple times. We are also now completing our programmed testing results and will update this repo soon.
However, at this stage, we are inviting you to please review the contract zUnipool.sol and provide your feedback by creating issues or PR on the code.
A full video run down of one of the final use and internal testing (manual though) is available here
For internal testing purposes, there are some rough events internall; these will be removed in the final version and more formal events will be put in place.

The zUnipool contract rebalances the underlying reward of SNX by reinvesting it into LP tokens and re-staking it, everytime a user comes in (ie mints zUNI tokens) or gets out (ie redeems the zUNI tokens). This is a very critical stage. Considering the nuances of the Uniswap contract, the volume and that we have limited the trades to be done at only 0.5% slippage max, only when the SNX earned is above a certain amount of threshold, does the rebalancing gets triggered.
