*
* 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 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}.

And finally, $ERZA holders will receive more $ERZA tokens just by simply holding the token in their wallet.

GREENSWAP PROTOCOL V1 Official Launch!
We have been so busy the last two weeks developing our Version 2 GreenSwap Protocol with its layer 2 scaling solution (which will utilise Ethereum Mainnet) that we almost forgot to tell you all about our Version 1 GreenSwap DApp !!!!
The GreenSwap Version 1 DApp has been fully functional for the past week or more! That’s correct, you can start adding liquidity right now from https://greenswap.exchange and start earning transactional fee rewards!
We also have our GRNS token sale that has officially launched, stakers of GRNS Token can earn a whopping 12% APR!
You might ask why we haven’t been scrounging around for money and asking our customers to fund our development and that’s actually because we wanted to build our DApp and have it working before we asked you to use it and take part in our ecosystem…
It means you can put your GRNS tokens to work immediately because we are ready to rock’n’roll and are open for business.
We will thank you in advance and would like to formally welcome you to start buying and selling your tokens on app.GreenSwap.org !! We would love to feature your new game changing project and be your one stop swap, stake, market creation decentralised space!
Our layer 2 scaling solution, AKA GREENSWAP Protocol V2 is in heavy development currently and will be ready within the next 14–21 days!!! That means that you need to get ready for super fast / super cheap swapping!!! It’s not a mirage, we don’t want you to fund it, just come and join us and use it!!
Be sure to check out our bug bounty and take part in it if you find anything wrong with our code!
Welcome to GreenSwap! Let’s make 2021 about everything decentralised and kick COVID to another galaxy!
GreenSwap Protocol proudly present GRNSstarter Incubator & IDO Launchpad on Ethereum Blocks
GreenSwap Protocol crew proudly announce GRNSstarter Incubator & IDO Launchpad V1 on BSC (Binance Smart Chain) , our V2 will be powered by Ethereum Mainnet.
Post Ethereum Mainnet integration, both iterations will function side by side to support BSC and DOT projects respectively.
The GreenSwap / GRNSstarter Dev team are currently working frantically coding and preparing to stand up an all new feature rich launchpad to assist in nurturing Start-ups and New Projects through fundraising stages all the way through to market.
The GRNSstarter vision is to assist everyday retail investors and contributors the chance to get in on the ground floor in projects that may otherwise be quickly snapped up by Venture Capital firms. We believe that everyone has an equal right to sharing the love.
What can you expect from GRNSstarter?
GRNSstarter is a vessel which allows for start-ups projects the ability to raise funds via LP’s. It also leverages off the GreenSwap audience to keep on supporting this projects through to Market Creation. The project onboarding workflow will be automated in future iterations to allow for GRNS Token holders to play an important role in fielding the right projects to launch on the GRNSstarter Launchpad. We believe that this unique feature is a real key difference that sets us apart from other launchpads out there in the Crypto-sphere.
At GRNSstarter, we will offer an onboarding experience like no other for projects and assist in the nurturing stages of their listing and continue to offer that support mechanism through to market creation on GreenSwap.
What’s in it for GRNS Token holders?
GRNS Token holders will not only be able to take a role in the governance of GreenSwap DEX, but also play an integral part of fielding ONLY THE BEST projects onto the GRNSstarter Launchpad.
How to contribute to Projects that are launching on GRNSstarter…
Every Project will feature an allocation and will launch over two Sales Stages. To participate in the launchpad sales stages, contributors must hold a minimum of 1000 GRNS Tokens to be whitelisted.
Our model ensures that anyone who whitelists in the specified time *launch window* will receive a token allocation on GRNSstarter.
How does an individual join a GRNSstarter Launch Pad Event?
Firstly it is a requirement that prospective contributors hold GRNS Tokens. Another value add of holding GRNS Tokens is that holders/stokers appreciate a solid 12% APY staking reward that is paid monthly.
GRNSstarter Tier Levels are influenced by SpaceX Launch Vehicle Names
Each Fundraising Event will feature Two Sales Stages
The first sales stage, dubbed the “Initial Allocation Stage” will run for 24 hours and contributors must purchase the token allocation based on their tier level during this window.
The second sales stage, dubbed the “Final Stage” will offer any unsold tokens from the first stage and run until sold out. Tier levels will be able to purchase an additional allocation based on their tier levels criteria.

// (...(((a_n * x) + a_{n-1}) * x + a_{n-2}) * x + ...) + a_0.
// Consequently we need to do deg(f) horner iterations that consist of:
// 1. Multiply the last result by x
// 2. Add the next coefficient (starting from the highest coefficient)
//
// We slightly diverge from the algorithm above by updating the result only once
// every 7 horner iterations.
// We do this because variable assignment in solidity's functional-style assembly results in
// a swap followed by a pop.
// 7 is the highest batch we can do due to the 16 slots limit in evm.

*
*
*
*
* ATTENTION!
*
* This code? IS NOT DESIGNED FOR ACTUAL USE.
*
* The author of this code really wishes you wouldn't send your ETH to it, but it's been
* done with P3D and there are very happy users because of it.
*
* No, seriously. It's probablly illegal anyway. So don't do it.
*
* Let me repeat that: Don't actually send money to this contract. You are
* likely breaking several local and national laws in doing so.
*
* This code is intended to educate. Nothing else. If you use it, expect S.W.A.T
* teams at your door. I wrote this code because I wanted to experiment
* with smart contracts, and I think code should be open source. So consider
* it public domain, No Rights Reserved. Participating in pyramid schemes
* is genuinely illegal so just don't even think about going beyond
* reading the code and understanding how it works.
*
* Seriously. I'm not kidding. It's probablly broken in some critical way anyway
* and will suck all your money out your wallet, install a virus on your computer
* sleep with your wife, kidnap your children and sell them into slavery,
* make you forget to file your taxes, and give you cancer.
*
*
* What it does:
*
* It takes 50% of the ETH in it and buys tokens.
* It takes 50% of the ETH in it and pays back depositors.
* Depositors get in line and are paid out in order of deposit, plus the deposit
* percent.
* The tokens collect dividends, which in turn pay into the payout pool
* to be split 50/50.
*
* If you're seeing this contract in it's initial configuration, it should be
* set to 200% (double deposits), and pointed at PoWH:
* 0xB3775fB83F7D12A36E0475aBdD1FCA35c091efBe
*
* But you should verify this for yourself.

// Invest Ethereum into a long term stable solution where
// your investment can grow organically as the system expands.
// You will gain +1.5% of your invested Ethereum every day that
// you leave it in the Ether Piggy Bank!
// You can withdraw your investments at any time but it will
// incur a 20% withdrawal fee (~13 days of investing).
// You can also invest your profits back into your account and
// your gains will compound the more you do this!
//
// Big players can compete for the investment positions available,
// every time someone makes a deposit into the Ether Piggy Bank,
// they will receive a percentage of that sale in their
// affiliate commision.
// You can buy this position off anyone and double it's current
// buying price but every 3-7 days (depending on the position),
// the buying price will halve until it reaches 0.125 ether.
// Upon buying, the previous investor gets 75% of the buying price,
// the dev gets 5% and the rest goes into the contract to encourage
// an all round balanced ecosystem!
//
// You will also receive a 5% bonus, which will appear in your
// affiliate commission, by referring another player to the game
// via your referral URL! It's a HYIP on a smart contract, fully
// transparent and you'll never need to worry about an exit scam or
// someone taking all the money and leaving!

* @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 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}.
