*
* Pyraminu is a meme token with a twist!
* Pyraminu has no sale limitations, which benefits whales and minnows alike, and an innovative dynamic reflection tax rate which increases proportionate to the size of the sell.
*
* TOKENOMICS:
* 1,000,000,000,000 token supply
* FIRST TWO MINUTES: 3,000,000,000 max buy / 45-second buy cooldown (these limitations are lifted automatically two minutes post-launch)
* 15-second cooldown to sell after a buy, in order to limit bot behavior. NO OTHER COOLDOWNS, NO COOLDOWNS BETWEEN SELLS
* No buy or sell token limits. Whales are welcome!
* 10% total tax on buy
* Fee on sells is dynamic, relative to price impact, minimum of 10% fee and maximum of 40% fee, with NO SELL LIMIT.
* No team tokens, no presale
* A unique approach to resolving the huge dumps after long pumps that have plagued every NotInu fork

/*
Atlantis or ATIS, is Mammoth Corp's primary ecosystem token where profits from its games and future platforms are shared.
ATIS is a low supply, deflationary token backed by a locked liquidity pool on Uniswap, where it primarily trades.
It will be further supported by Mammoth's Capital Fund Token, which will include profit sharing from MCAP, delivering additional dividends to ATIS stakers.
Future DEX and possible CEX listings will be sought for ATIS in the future as the platform grows.
About Mammoth - Mammoth Corp was incepted in the hearts and minds of the cryptocurrency community in early 2020.
Since then, we have grown into a large collective of like-minded individuals who value the growth and adoption of blockchain technology as well as the merits of decentralized protocols and applications.
Our core principles are decentralization, transparency, and open-source development. Our goal is to deliver quality gaming based on those principles.
Thank you for joining us and welcome to our community here at Mammoth Corp, come be a Mammoth with us and build something... BIG!
Velantis or VTIS, is Mammoth Corp's secondary gaming token to be used in it's in-house games and dapps. Additionally, it will be used for entry into Mammoth's Capital Fund token from the second round of it's sale onward.
There will only be a limited supply of MCAP which will make VTIS a desirable token within the ecosystem. Gaming dapps are planned to include a slow supply drip called GENESIS, Raffles, and Hourglasses.
Remaining portion will be allocated between Team, MCAP, and future dapps. A detailed breakdown can be found within our Whitepaper linked within the page.
Mammoth Capital Fund or MCAP, is Mammoth's investment portfolio which will serve to add value to the project by investing a portion of its earnings into top traded cryptocurrencies, stable coins, decentralized applications, projects, and potentially more.
By taking decentralized concepts, such as DAO voting, and applying them to it's growth philosophy, we believe in a community driven approach to the building and development of our project and it's portfolio.

/*
DEFI is a rapidly growing sector within crypto, and it will be an essential part of
tomorrow's economy. However, there are currently few incentives within most DEFI
projects that are aligned with what the requirements for DEFI, and cryptocurrency in
general, to grow. Only attracting other current cryptocurrency enthusiasts is not
enough, and will cap the growth of DEFI.
All the while, fiat inflation is occurring at a rapid pace, and projects that incentivize
outreach are needed to secure the communities' financial stability that we exist on a
day-to-day basis outside of our online lives. As we see it, a project is necessary whose
goals are aligned with the requirements needed to help solve both of these issues.
Make no mistake, this project will proliferate initially due to interest within the DEFI
space, and then the cryptocurrency community at large. However, we question
whether price appreciation alone is enough to propel a project that will further grow
the DEFI market. As such, we propose a project that rewards its community for
reaching out to social circles outside of DEFI
Community is the basis and core of the project. Everyone needs to be working united
towards a common goal. We have developed a structure that keeps the community
and future success of the project tightly bound together.
Proof of Shill or PoSH concept: a staking mechanism activated by the growth of the
community.
Staking
Shill & Win rewards the community with staking. Each user gets their reward payout daily.
5% of the reward goes to their upline or the staking pool by default.
Inviting friends that stake will earn you 5% of all their staking rewards!
Staking has a 5% fee and unstaking has a 25% fee, which goes directly to the staking pool.

VOYAGER
(VGER)
A UniLaunchpad Project
Website: https://UniLaunch.io
Telegram: https://t.me/unilaunchpad
Twitter: https://twitter.com/UniLaunchpad
UniLaunchpad is launching a new token on Uniswap every day
4% token burn per transfer for VGER
40,000 VGER initial supply + 40 ETH
FAIR LAUNCH FEATURE - Any Buys above 250 Tokens within the first 40 Blocks(10 Minutes)
pay marginal 25% burn fee for the amount above 1000
***BONUS 1 RCKT token for every VGER token burned in transactions***

/*
We introduce Rapid Swap, a collision and front-running resistant decentralized exchange protocol on Ethereum BlockChain that integrates verifiable delay functions (VDF) as a proof-of-elapsed-time to resolve same-block order conflicts while preventing front-running attacks. Our proposal is the only decentralized exchange protocol that is very quick, publicly verifiable, resolvable, liquidity neutral, and front-running resistant.
1. Introduction
This is the summer of DeFi. We’ve seen the release and growth of hundreds of projects in the space, which together have created a more powerful DeFi network; clean, intuitive interfaces; and an explosion in locked value. We’ve also seen the introduction of several new, novel projects.But the novel and well-designed aren’t the same things, and many of the underlying weaknesses of DeFi remain.
1.1. Speed and Usability
Above all else, DeFi is slow and expensive. It costs dollars to do a trade, and minutes for it to clear. This is fine for some use cases-but many customers prefer the fast, cheap execution of centralized exchanges. It’s hard to stare at your Metamask wallet waiting for a trade to be confirmed without missing centralized exchanges
1.2. Centralization
When you trace all the way through, most DeFi protocols bottom out in a centralized oracle-often in the most crucial step.Sometimes, this is a liquidation price oracle pointing to centralized exchange APIs. Other times it’s a council of token holders. Sometimes it’s the team of the protocol itself.
There’s a further problem too — most decentralizing protocols are computationally intensive. Fitting them into the ETH blockchain in a way that is cost-efficient and fast has mostly eluded the space.
That’s not to say that centralization is always bad! USDT, USDC, and similar tokens are great projects which have revolutionized the entire crypto industry. They power much of the volume, and if you want something that can be turned into a dollar 24/7 that’s the only game in town and probably always will be. Because fundamentally dollar bills aren’t on the blockchain, they’re in bank accounts.
1.3. Orderbooks
Uniswap has quietly revolutionized DeFi by allowing trading without order books.But the more remarkable thing is that Automated Market Making is necessary. AMM is a system where there are no limit orders, or even bids or offers; in an order book, you can decide the price, size, and direction you want to trade.
There are lots of disadvantages to AMM. You can’t provide liquidity unless you provide both sides; you can’t choose to only provide at a particular price; you can’t provide at a price other than the current market price, and you can’t select the size to provide there without providing way more behind it.
There’s a solution to this–it’s what the rest of finance does. But DeFi doesn’t have order books, by and large, because the ETH network is too slow and expensive to support them. Matching bids and offers with each other involve a bunch of operations.
1.4. Cross-chain Support
There have been many attempts at cross-chain support. WBTC is probably the most known, creating an ERC20 token wrapping BTC; Thorchain is building an entire protocol that allows for complete, fast cross-chain support.
There are lots of ways to attempt it. One thing all of the current versions have in common, though, is an oracle, or panel of token holders, or some other place where the truth is decided by people expected to be honest. Because, fundamentally, BTC isn’t on Ethereum, so how can a smart contract know or impact its transfers?
Enter RAPID SWAP Protocol!
Rapidswap is not perfect; nothing is. There are fundamental tradeoffs between speed and decentralization; sophistication and ease of use. But RAPIDSWAP is different, and it’s powerful. Its software enables a fast DEX; it has cross-chain support, stable coins, wrapped coins, order books, and the ability to create custom and novel financial products; and while having all of those, it’s fully decentralized. There are no oracles to centralized price feeds; no tribunals whose honesty you rely on. Rapidswap is pure DeFi. And unlike current DeFi, it’s very fast and cheap.
2. Project RAPID SWAP
Project Rapidswap will unveil a fully functional decentralized exchange with trustless cross-chain trading, all at the speed and price that customers want. And despite living natively on Ethereum BlockChain, it will be interoperable with Ethereum. Rapidswap made of seven main ingredients:

⚡️No Presale
⚡️No Team Tokens
⚡️Initial ETH for liquidity provided by the team
⚡️Complete fair launch
⚡️Stealth launch
✅Numerous Anti-bot measures in place.
✅Liquidity will be locked on unicrypt after it’s added.
✅Ownership will be renounced, straight after launch.
✅There will be no presale, to prevent an unfair launch.
✅We will provide liquidity ourselves! We will take no team tokens! (5% tax on sells only)
✅ To get the coin starting off strong. Influencers are on board and ready to go!
✅Coingecko listing has been drafted, 4 Chan, plans to get this trending on dextools will be undertaken straight after launch.

* @dev Wrappers over Solidity's arithmetic operations with added overflow

* Arithmetic operations in Solidity wrap on overflow. This can easily result
* in bugs, because programmers usually assume that an overflow raises an
* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.
