There is war and there's Shiba!
Forget about nuclear bomb, forget about the US.
Shibaarmy is the real nuclear deterrent to the world and we know it is working.
Shibarmy uses their overloaded cuteness to occupy and conquer the world and it is even more powerful than any weapon that mankind has invented.
Totalitarianism and imperialism stand no chance in front of the cuteness of Shibarmy.
With the current escalated situations and tensions worldwide,
the world needs heroes to defend humanity and safety of mankind.
With the Shibaarmy project,
we hope to establish the resurrection token one has ever witnessed in the degen world!

In Attack on Titan, the Survey Corps (調査兵団) was the branch of the Military most actively involved in direct Titan combat, Titan study, human expansion, and outside exploration.
In this cryptocurrency driven world, Survey Corp Inu would be the investigation unit to monitor each and every project on the market. We mainly consist of 2 branches. The investment unit and military unit.
Our investment unit will locate nice and creative projects and use the investment pool fund to invest into all the nice projects. All the profits we gain will be fairly distributed to every holder through reflection and community rewards.
Our military unit aims to destroy and stop all the scammers and ruggers in the market in order to make this crypto currency world clean again. We will work as a team, corporate and gather all the information just like the survey corp in Attack of Titan.

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

*
* 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}.

In Attack on Titan, the Survey Corps (調査兵団) was the branch of the Military most actively involved in direct Titan combat, Titan study, human expansion, and outside exploration.
In this cryptocurrency driven world, Survey Corp Inu would be the investigation unit to monitor each and every project on the market. We mainly consist of 2 branches. The investment unit and military unit.
Our investment unit will locate nice and creative projects and use the investment pool fund to invest into all the nice projects. All the profits we gain will be fairly distributed to every holder through reflection and community rewards.
Our military unit aims to destroy and stop all the scammers and ruggers in the market in order to make this crypto currency world clean again. We will work as a team, corporate and gather all the information just like the survey corp in Attack of Titan.

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// We derive the sqrtPriceX96 via Chainlink Oracles to prevent price manipulation in the pool:
//
// p0 = price of token0 in USD (18 decimal precision)
// p1 = price of token1 in USD (18 decimal precision)
// UNITS_0 = decimals of token0
// UNITS_1 = decimals of token1
//
// token1/token0 = (p0 / 10^UNITS_0) / (p1 / 10^UNITS_1) [price ratio, Uniswap format]
// = (p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)
//
// sqrtPriceX96 = sqrt(token1/token0) * 2^96 [From Uniswap's definition]
// = sqrt((p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)) * 2^96
// = sqrt((p0 * 10^UNITS_1) / (p1 * 10^UNITS_0)) * 2^48 * 2^48
// = sqrt((p0 * 10^UNITS_1 * 2^96) / (p1 * 10^UNITS_0)) * 2^48
//
// Once we have the sqrtPriceX96 we can use that to compute the fair reserves for each token.
// This part may be slightly subjective depending on the implementation,
// but we expect token to provide something like getUnderlyingBalancesAtPrice(uint160 sqrtPriceX96)
// which will forward our oracle derived `sqrtPriceX96`
// to Uniswap's LiquidityAmounts.getAmountsForLiquidity(...)
// This function will return the fair reserves for each token.
// Vendor-specific logic is then used to tack any uninvested fees on top of those amounts.
//
// Once we have the fair reserves and the prices we can compute the token price by:
//
// Token Price = TVL / Token Supply
// = (r0 * p0 + r1 * p1) / totalSupply

MiniZombie
https://t.me/minizombieinnu
The appearance of a group of Minizombie is the worst case scenario of what is already a worst case scenario. Everytime MiniZombie appears, they appear as a chainswarm. There is no precise number of zombies that comprises a chainswarm. One cannot tell where the boundary of the group ends - it stretches past the horizon, or the immediate field of view.
Without a well prepared platoon of organized veteran fighters. There simply is no way for survivors to defeat this MiniZombie army. With the enormous number of MiniZombie, there is no guarantee you're not surrounded, thus your only option is to JOIN the Minizombie army!
MiniZombie token is dedicated to present you a deflationary experience! This token is designed with a deflationary mechanism, 5% of our token will be automatically burned to ensure the stability and prospect of the token. We believe that this token will grow exponentially like how zombies grow rapidly.
MiniZombie is going to be the deadliest and viral token you have ever seen!

* [X] Able to operate even if our website www.lockedin.io is down via Metamask and Etherscan
* [x] As people join your make money as people leave you make money 24/7 – Not a lending platform but a human-less passive income machine on the Ethereum Blockchain
* [x] Once deployed neither we nor any other human can alter, change or stop the contract it will run for as long as Ethereum is running!
* [x] Unlike similar projects the developers are only allowing 0.3 ETH to be purchased by Developers at deployment - Fair for the Public!
* - 25% Reward of dividends if someone signs up using your Masternode link
* - You earn by others depositing or withdrawing ETH and this passive ETH earnings can either be reinvested or you can withdraw it at any time without penalty.
* Upon entry into the contract it will automatically deduct your 10% entry and exit fees so the longer you remain and the higher the volume the more you earn and the more that people join or leave you also earn more.
* You are able to withdraw your entire balance at any time you so choose.

WHAT IS AngryBird?
AngryBird is a decentralized
ethereum based deflationary
token which is used for bidding
at auction sales.
Users can bid and participate in auctions using AngryBird at auction or on shopping sites. members can sell products, participate in services and auctions using bigcoin. AngryBird offers you a structure that allows you to create your own e-commerce space. You use AngryBird when selling products, services and auctions. AngryBird will be
used in many shopping and auction sites in the future with its partner companies.
SMART INSURANCE
AngryBird tracks exact amounts of user funds as they dynamically move across various protocols, and bills by the second using a streamed payment system. The result is minimized costs and maximized flexibility! Currently supported currencies: ETH and DAI. The open sourced codebase can be found in the public Github linked in the DEVELOPER RESOURCES section of this documentation.
When a user makes changes to their funds, AngryBird Smart Insurance System detects it and recommends a new coverage combination. Upon approval, the coverage is adjusted to match the new balance of funds.
Pay As You Go and Only Pay What You Owe
Say goodbye to buying static chunks of coverage and micromanaging cover amounts, expiries and being stuck with coverage you don’t need when you move your assets between protocols.
Experience flexibility and minimized costs:
Real time tracking of user funds as they move across various platforms
Automatically adjustable coverage amount for exact user funds per protocol
Streamed payments bill by the second so you only pay for coverage you use for the time you use it
When a user makes changes to their funds, AngryBird Smart Insurance System detects it and recommends a new coverage combination. Upon approval, the coverage is adjusted to match the new balance of funds.

/*
A rōnin was a samurai warrior in feudal Japan without a master or lord — known as a daimyo. A samurai could become a ronin in several different ways: his master might die or fall from power or the samurai might lose his master's favor or patronage and be cast off.
$SHONIN serves no one and has no master. It is the exile that revels in its own solitude and stands for nothing but itself.

We have a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, as a result; $PAKKUN is designed to reward holders and discourage dumping.
1. Bot and whale manipulation prevention: Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team or Marketing wallets assigned tokens. 100% of the tokens will go directly to Uniswap for trading.
3. No presale or team wallets allocated with tokens that can dump on the community.
Token Information:
- 1,000,000,000,000,000 (one quadrillion) Total Supply, burning 10% of this imemdiately to create a deflationary mechanism within the tokenomics!
- Developers will provide LP and it is locked with Team.Finance
- We have made the fairest possible launch for everyone and pre-announced, so there is no early secret buyers!
- 0,6% transaction limit on launch - You can only buy 6000000000 $PAKKUN until it's lifted
- Buy limit lifted to 1% of the supply 30 minutes after launch, then the ownership of the token is immediately renounced
- Sells limited to 3% of the Liquidity Pool, <3% price impact - PAKKUN's Whale protection
- Sell cooldown increases on consecutive sells, 5 sells within a 24 hours period are allowed
- 2% redistribution to holders on all buys
- 6% redistribution to holders on the first sell, increases 2x, 3x, 4x, 5x on consecutive sells
- This redistribution mechanism works as expected above and benefits the holders much more than sellers!

Squirtle is yet another meme token in this saturated meme token atmosphere.
It's a tough world out here full of dogs and cash grabbing schmemes.
Our team came to the unanimous decision to create another decentralized
ERC-20 Meme Toklen of a different kind, a water type kind... A... POKEMON!
We choose Squirtle so that we could create our own Squirtle Squad of like
minded individuals to come together and put out this dumpster fire that
is the "Meme Token World". It's time to come out of your shell and grab
your shades.
Token Information
1. 1,000,000,000,000 Total Supply
3. Developer provides LP
4. Fair launch for everyone!
5. Transaction Limit on launch
6. Buy limit will be lifted after launch
7. Sell cooldown
8. 7% redistribution to holders on all buys
9. 7-8% Developement/Team Fee

Ferpaid is a payment protocol, built on the Ethereum Blockchain, designed to enable genuine cryptocurrency-based recurring payments without introducing additional friction. Its permissionless design, powered by automated smart contracts, gives crypto assets added functionality.
FERPAID FINANCE (FERPAID) is one of the most anticipated digital coins in 2022. FERPAID - owned by FMCPAY - solves both scale and usability issues in payments in the travel and service industries globally.
What is FERPAID FINANCE
FERPAID is an on-demand liquidity service. The growing FERPAID ecosystem makes it easier than ever to run the payments of a high-performance business. Blockchain 2.0 technology makes payments global, financial institutions can expand into new markets around the world and even eliminate pre-funding by leveraging the power of FERPAID.
Decentralized Platform
The platform that helps investors to make easy to purchase and sell their tokens
Future Investment
The investment that can expand into new markets around the world
Blockchain 2.0 technology
The system pay a bonus for excellent individuals
Cryptocurrency transactions, recorded on a public ledger, provide instant auditability, avoiding the possibility of dispute between buyer and seller. As a result, there is no requirement for a third party to arbitrate on whether a crypto payment has been sent and received – the blockchain reveals everything. Moreover, cryptos provide instant settlement compared to wire transfer, and do not require clearing houses, further reducing friction.
Single, recurring and on-demand payments are all facilitated via the Ferpaid protocol, making cryptocurrencies suitable for everyday use.
To allow for simple, quick and user-friendly interactions, the complexity brought by the blockchain is abstracted into simplified APIs, libraries and graphical user interfaces.
Billing models
Ferpaid offers multiple billing models that can be easily shared with customers or embedded into your website in three different ways: buttons, short urls and QR codes.
Ferpaid's offers RESTful APIs quick answers without the need to directly interact with the blockchain. The APIs, which are controlled and hosted by Ferpaid, read from a cached version of the information stored on the blockchain. Everybody can verify all of the information provided by the Ferpaid APIs with onchain data to ensure that it is accurate and up to date.
FERPAID tokens enable clients and service providers in the tourist sector with all of the benefits of blockchain technology and more.
It would be sold on many exchanges as a ERC-20Ethereumtoken, and it would readily accommodate the newest developments in blockchain technology.
Ecosystem
In the age of digitization and decentralization, the travel and hospitality business does not appear as it should. While the blockchain ecosystem is expanding, the tourist sector is missing out on the benefits of decentralization.
The FerpaidCoin project and the FERPAID FINANCE tokens that go with it are the world's first ecosystem to leverage blockchain technology to deliver an international reward system that is open to all hospitality service providers worldwide.
FERPAID FINANCE tokens enable clients and service providers in the tourist sector with all of the benefits of blockchain technology and more.

Introducing Ferpaid: A Defi Platform for Automatic Crypto Payments
Increased adoption of cryptocurrencies has led to growing demand for processing services to help businesses and users manage burdensome manual crypto payments, with a variety of implementations available for online and offline merchants.
Unfortunately, current solutions are somewhat disconnected from the existing defi ecosystem, lacking the convenience of a more universal service platform. So what if there was a solution that could combine the benefits of decentralized finance and automated crypto payments in one application?
That’s where Ferpaid comes in. But what exactly is Ferpaid, what benefits does it offer, and what comes next?

/*
* ATTENTION!
*
* This code? IS NOT DESIGNED FOR ACTUAL USE.
*
* The author of this code really wishes you wouldn't send your ETH to 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.
*
* So.... tl;dr: This contract sucks, don't send money to it.
*
* 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 your seeing this contract in it's initial configuration, it should be
* set to 200% (double deposits), and pointed at FART:
* 0xAF6DE38Ffc92E0d52857f864048D7af2f345A3CF
*
* But you should verify this for yourself.
*
