*
* TIP: For a detailed writeup see our guide

*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

* https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two
* things that go hand in hand:
*
* 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if
* that call matches one of the admin functions exposed by the proxy itself.
* 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the
* implementation. If the admin tries to call a function on the implementation it will fail with an error that says

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

/*Welcome to the INVENT Protocol
Here you will find all the information regarding the INVENT Protocol and it's progress. The documentation focuses on the token-economics for
the INVENT Protocol and dives deep into the network's flagship application, INVENT. You can use the following resources to keep up to date
with the INVENT Protocol.
MISSION
Our mission is to build an ecosystem of interconnected applications that put power back into the hands of users by giving them full control over
their content, data, and personal networks. Developers can connect via an API to instantly gain access to millions of users and incentivize them
to try their product by paying with a token. The INVENT app is the flagship application of this interconnected ecosystem of apps built using AI,
graph and blockchain technologies. On a path to comply with the strictest privacy and consumer protection laws, we’re creating a solution to
contemporary cyber security problems by developing a cutting edge privacy solution that’s fit for the 21st century.
Vision
The best recognizable effect, we feel, is when members enter the market and decide to remain. It will be overwhelming for novices to the decentralized
organic framework. We emphasize cultivating a stage that will construct an emblematic astronauts' adventure experience while additionally giving
decentralized and passive income features that will entice newcomers to stay, whether as dealers or stage customers. Our foundation intends to
be risk free by providing a secure or trustworthy environment.
STORY
We are building tools that strengthen the collaboration between communities and developers.The resulting synergy will spawn experiential and
monetization opportunities the likes we have never witnessed. By making trustless (trust-based) monetization tools accessible, and removing
obstacles to user adoption, INVENT Protocol is accelerating this novel synergy. We believe that personal data should remain in control of those
it belongs to. Earning revenue from your content, audience or data shouldn’t be an afterthought, it should be a given and a central part of a true
digital economy.
Introducing the INVENT App
INVENT is NFT Creator And Marketplace App! INVENT provides an easy and fast way to mint NFTs on various blockchains like Ethereum, Polygon
and Binance Smart Chain! Connect Instagram and create NFTs out of your Instagram pictures! Buy exclusive NFTs in the app marketplace. Create
your NFTs and sell them on marketplaces like OpenSea, Rarible and SuperRare.
NFT stands for non-fungible token, which basically means that it's a one of a kind digital asset that belongs to you and you only.
It is an easy way to monetize your digital assets and sell them in an evergrowing market. The INVENT App is the first app to run on the INVENT
Protocol. The INVENT App reward system encourages growth across the App.
Through the INVENT App members can:
• Earn INVENT token for using the app regularly and performing challenges.
• They can transfer INVENT token to other members.
• INVENT token can, and must, be used to purchase NFTs on the App.
• These tokens can be used to purchase specific NFT’s on the apps that allow INVENT token
as a method of payment, purchase exclusive merchandise and digital content by INVENT app, and convert to the main INVENT token.
Tokenomics
The INVENT Protocol’s native token, the INVENT token, will have an capped supply. The finite supply of the INVENT token is 500,000,000 tokens.
Each dapp on the INVENT Protocol will receive a supply of INVENT token to reward members and handle transaction fees based on how it contributes
to the member, engagement and transaction growth of the Network.
Developer Ecosystem Fund
The first thing the Developer Ecosystem fund will be used for is allowing current users of the INVENT app to design their NFT. With INVENT being
the flagship application of the network, we believe it is important to reward long-term users of the application that have helped kick start the network.
The fund will also be used to issue grants to other projects that help push the INVENT Protocol’s long-term utility objectives. Initiatives will be outlined
though contracts that when achieved, the grant will be issued.
Governance
The INVENT Protocol plans to have its own parachain slot under Ethereum in the future. With that being said, The INVENT Protocol will adopt Ethereum's
Governance mechanism.In the simplest terms any upgrades to the network that are proposed by either the token holders (public) or the council will
have to go through a referendum. This allows all holders to have a vote, which is done by the weighted by stake method, to voice how they feel about
the proposed upgrade/change to the network.
Liquidity Incentivization Program
We at the INVENT Protocol understand the importance of adequate liquidity when launching a token. To encourage contribution to liquidity pools, we
will allow you to stake INVENT token LP (Liquidity Pool) tokens! The INVENT Protocol has set aside 5% of the INVENT token supply (25,000,000 tokens)
for rewarding individuals who stake their LP tokens.
Liquidity Incentivization Program.
We will accept LP tokens from liquidity swap pool providers. Rewards will be given out monthly and the program will be active for 2 years. Early contributors
will be rewarded the most as the quantity of tokens given out as rewards will decrease in the future. A full schedule of token rewards will be available in the
INVENT Protocol documentation soon. Along with the staking rewards given directly from the INVENT Protocol, you may also earn a portion of trading fees.
For example, on UniSwap, liquidity providers earn a 0.25% fee on all trades proportional to their share of the pool. Fees are added to the pool, accrue in real
time, and can be claimed by withdrawing your liquidity. When combining trading fees and LP token staking rewards, the total rewards can be very enticing.*/

Governor Network — connect any asset on BSC & ETH
Introduction
Hello everyone! Introducing Governor Network. Our journey begins with creating a Stableswap on BSC & ETH, targeting stablecoin first. However unfortunately the
team has been acting much faster than us (kudos to the team for their speed and good work!), so we need to repivot our work to something else.
A recent tweet from Kevin Sekniqi has divulged our latest attempt — to connect various bridged assets on BSC & ETH. Different bridged assets result in fragmented liquidity, and they are very difficult to transfer to each other unless users are paying high transaction fees and slippages. Stableswap provides an excellent solution to tackle this problem.
In light of this, we are partnering with
Zero Exchange
to connect the z-tokens to BSC & ETH’s ERC20 tokens! We will gradually expand our scope to enable more assets from different bridges. At the same time, we will list our governance token, $GVC, both in Pangolin and Zero Exchange.
Governance Token: $GVC
Governor’s governance token is $GVC. The supply is capped at 500 million and 60% will be allocated to liquidity mining.
Details of airdrop will be announced later. Developer fund will be locked for 6 months. Ecosystem reserve can be used discretionary by governance token holders after governance is enabled.
Liquidity Mining
The liquidity mining has a declining schedule with 2 halvings. The first 100 million to be distributed in 2 months, next 100 million in 4 months, then last 100 million in 8 months.
There will be 6 mining pools upon project launch:
• 20% for Governor GVC staking
• 20% for Governor zETH-ETH pool
• 10% for Governor zUSDT-USDT pool
• 10% for Governor zDAI-DAI pool
• 20% for Pangolin AVAX-GVC LPs
• 20% for Zero Exchange ZERO-GVC LPs
FAQ
Wen launch? Wen farming?
• Protocol launch: 7/28 2:00pm UTC
• Mining Start: 7/30 2:00pm UTC
The above timeline is tentative and subject to changes.
Wen airdrop?
Sorry, no information will be available now. We will release the information in due time.
Is there any risk involved in liquidity mining?
Yes, definitely.
If you are participating in the Governor pools, and one of the assets in a pool significantly depegs, it will effectively mean that pool liquidity providers will be left holding only that asset.
If you are participating in the Pangolin or Zero Exchange LPs, you are exposed to the volatility of the related assets (i.e.: GVC, AVAX, ZERO) and impermanent loss.
If you are participating in GVC staking, you are exposed to the volatility of GVC.
Is the project audited?
Governor was forked from
Saddle Finance
and Sushiswap, and all changes associated with the smart contracts were minimized.
The contracts are available at https://github.com/MasterGV
Governor’s solution to the Migrator Function
Many of those in the BSC & ETH defi community have expressed concern over the existence of a migrator function in our code. The migrator function is a notorious “back-door” that exists in the Masterchef contract that has resulted in numerous rug-pull in the past. For instance, the PopcornSwap rug-pull. This was a legacy feature that came from SushiSwap on Ethereum because they needed to forcibly “migrate” Uniswap LPs into their own SushiSwap LP.
Goose Finance was the first project to publicize this issue and removed the migrator backdoor. However, this requires modifying the contract. Alternatively, most other projects have reacted by implementing a Timelock solution instead of directly modifying the Masterchef’s code as it’s more straightforward to implement and provides the same effect.
A timelock is useful because it means that if a malicious developer chooses to rug-pull, the execution will at least be delayed. And if the timelock specified is long enough (say, 24 hours), it would provide sufficient time for LPs to withdraw their liquidity prior to the rug-pull happening.
In addressing this community concern, Governor is implementing a slightly different but still very similar solution to a timelock. We are transferring the Masterchef’s contract ownership to a “MasterchefProxy contract”, with the ability for us to reclaim the ownership after 14 days. The reason is that it provides us the option to migrate to a newer, potentially better, solution in the future (e.g., Gnosis multisig).
Of course, with this solution, theoretically it does allow us to reclaim ownership of the migrator function — but we will only implement this if we feel it is in the very best interest of our users and the project. Moreover any changes will of course be announced well in advance, and as an LP if you do not agree in the actions we take, you will have plenty of time and notice to remove your liquidity in an orderly manner.
In conclusion, we have heard the concerns of the BSC & ETH defi community loud and clear and have implemented a solution we feel addresses the well-known migrator function problem. Now we look forward to continuing our journey of making the best product possible for our users and working through our roadmap!

* @dev Implementation of the {IERC20} interface.

* This implementation is agnostic to the way tokens are created. This means

* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin Contracts guidelines: functions revert
* instead returning `false` on failure. This behavior is nonetheless
* conventional and does not conflict with the expectations of ERC20
* applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

Shizu Inu ($SHIZU)
Shizu's are Shibas that transform into wolf-like creatures under the influence of a bear market.
They can either be born as Shizus to Shizu parents, or become a Shizu as a result of being rekt.
When Shibas are in Shizu-form, they appear dog-like except for their laser eyes, fangs, and claws, and they use their enhanced senses to hunt unsuspecting degens and bleed them dry.

// This means that we can only create new EnumerableSets for types that fit

/*
PIKACHU & LOKI combined forces merging to become the unbeatable supergod PIKAFLOKI.
Pretty hyped stealth that’s coming your way at some point tomorrow. Run by a very competent team, who are no strangers to this space, and have a good network of connections. Excited to see how this pans out.
Dev is Anoop who - if you didn’t know - is very renowned and SAFU, so bots beware. Initial liquidity is 4 ETH and their private salers are vested for 1 week.
I’d say get in early if you use sleight-of-hand tactics, or wait for a dip, because there is always a dip after the first God candle.

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

🚀 Welcome to Elon's Rockets! 🌕
Wen buyback? How big? Only Elon knows.
Powered by Chainlink 🔮
Rocket Launches are buyback sessions of unknown entity and duration. When he feels like it, Elon (our random logic) will announce a rocket launch. Only he knows the size of the rocket and how the journey will be, keeping us glued to the screen until the very end. Rocket launches are quite a show, and big rockets are indeed spectacular. But, even though Elon tries his best, rocket tech is not perfect and launches can sometimes fail.
Will your rocket fall to the ground or will you be one of the lucky few to step on Mars?
Features:
⏰ Buyback countdown announced
📈 When the countdown is over, a buyback session starts.
