* https://t.me/FoundOnNet
*
*
*Found On Internet is a meme token with a twist!
*Found on Internet 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

We appreciate the Myobu devs for their gigachad tokenomics
And above all we appreciate the devs at INTOXINU for providing
the foundational code that provided 90% of Myobu code base.
This project builds off of Myobu concepts and is designed to reward holders and discourage dumping.
Sell Cooldown Times:
1. First Sell - 1.5 hours
2. Second Sell - 3 hours
3. Third Sell - 9 hours
4. Fourth Sell - 1 day
1. Buy limit and cooldown timer (60 sec) on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will come on the market for trade.
3. No presale wallets that can dump on the community.
Token Information
1. 1,000,000,000,000 Total Supply
3. Developer provides LP / Gets small fee
4. Fair launch for everyone!
5. 0,2% transaction limit on launch
6. Buy limit lifted after launch
7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact
8. Sell cooldown increases on consecutive sells, 4 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 7% redistribution to holders on the first sell, increases 2x, 3x, 4x on consecutive sells
Marketing paid
Liqudity Locked
Ownership renounced (after open)
No Devwallets

// INVARIANT k = reserve0 [num token0] * reserve1 [num token1]

// k = r_x * r_y
// r_y = k / r_x

// 50-50 pools try to stay balanced in dollar terms
// r_x * p_x = r_y * p_y // Proportion of r_x and r_y can be manipulated so need to normalize them

//This file contains a multisignature wallet contract that is used to control the eRAY token contract:
// - to set the settings of token generation round
// - to start and to stop token generation round
// - to freeze the token upon creation of array.io blockchain
// - to send eRAY tokens from this wallet
// - to make arbitrary transaction in usual to multisignature wallet way
// Elsewhere in other contracts or documentation this contract MAY be referenced as projectWallet

/**
* @dev computes e ^ (x / FIXED_1) * FIXED_1
* input range: 0 <= x <= OPT_EXP_MAX_VAL - 1
* auto-generated via 'PrintFunctionOptimalExp.py'
* Detailed description:
* - Rewrite the input as a sum of binary exponents and a single residual r, as small as possible
* - The exponentiation of each binary exponent is given (pre-calculated)
* - The exponentiation of r is calculated via Taylor series for e^x, where x = r
* - The exponentiation of the input is calculated by multiplying the intermediate results above
* - For example: e^5.521692859 = e^(4 + 1 + 0.5 + 0.021692859) = e^4 * e^1 * e^0.5 * e^0.021692859

* チョコボ 🐥🐥🐥
* Chocobo, also called Chocob, is a recurring animal in the series of Final Fantasy. Large avian creatures, chocobos roughly act as the equivalent of horses, being domesticated for use as mounts, for pulling carts and carriages and for racing. Chocobos are known to be intelligent and to understand human language.
* Chocobos can usually be found in chocobo forests situated throughout the world. They come in several varieties. The regular chocobos can be used to travel around the world, but they flee when dismounted. In several series, a chocobo eats a chili pepper, it runs wildly due to the burning of the tongue.
* Chocobo Inu is the “proof of stake token” for CAW and SQUAWK. When you stake your Chocobo Inu token into the DAO, you are given CAW and SQUAWK. This can be swapped back at any time into the amount of Chocobo Inu you staked originally, plus any rewards that were given to the DAO in the time period you owned Chocobo Inu.

*
* 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}.

My name is Millie Monka
I love Meme Coins
And also you do
So I decided to open the doors of my Meme Coin Factory to you
Every 35 hours you can create a meme coin sending at least 1 ETH
you can choose name, symbol, and total supply
Meme Coin will be created and 99.98% of the total supply will be stored in a pool on UniswapV2 using eth you provided
remaining 0.02% of the Meme Coin total supply will be sent to Meme Coin creator so they can be swapped in future to have back creation fees
Resulting liquidity pool token will be held by the Meme Coin itself
the first burning 65% of the Meme Coin total supply will extract 60% of the pool
All Meme Coins removed from the pool will be burned
40% of removed eth will be sent to who burned tokens
47% of removed eth will be sent back to pool
remaining removed eth will be sent as Factory's fees
The remaining balance of liquidity pool token will be locked inside the Meme Coin forever
In Factory:
you have create(string memory name, string memory symbol, uint256 totalSupplyPlain) method to create a new Meme Coin. The amount is expressed in the decimal format so you DON'T HAVE TO multiply it for 1e18, Meme Coin will directly do it for you.
you have memeCoins() method to retrieve all Meme Coins in order of creation, including latest one
you have lastMemeCoin() method to retrieve the last Meme Coin only
you have nextCreationBlock() method to know when the next Meme Coin can be created
you have canBeCreated() method returning if nextCreationBlock reached and new Meme Coin can be created
In every Meme Coin:
you have the burn() method which will do all burn stuff descrived above for you
you have burnt() method to check if the 65% of total supply was already burnt or not
You can build a Telegram bot or fork the Uniswap frontend to easily use the Meme Coins
Hope you will enjoy my Meme Coin Factory,
I will do.
Yours,
Millie

*
* BCAKE is a meme token with a twist!
* BCAKE 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

A casino is a place that some people find similar to a hotel, where you can enjoy various types staying up all night but enjoying gambling activities at the same time.
However, Casino is actually a Colosseum. It is a place for gladiators to fight, to seize, to conqueror.
You either double your bet or you earn nothing if you are not a fighter material.
Living in a cryptocurrency world is exactly like gambling in a Casino; you need to play to earn your profit.
Shibagen is designed to tell those jeets. You either die like a gladiators or live long to see yourself becomes a stupid loser. Be bold, not jeets !

Order of the Shiba temple
In ancient Egypt, temples were seen as residences for deities, who were thought to temporarily manifest themselves in the cult statues located in the sanctuary. The temples were also the stage for daily rituals that were ideally performed by the supreme priests. These cultic performances included the offering of food and beverages as well as the burning of incense, which was thought to have a purifying effect.
In the contemporary crypto world, the sole purpose of setting up the Order of the Shiba temple is to create a sanctuary for every crypto believer to worship our great spiritual leader The Great Shiba. Here comes the guide of worship.
Shiba Worship Procedure Guide
Our Mission:
To invoke an atmosphere charged with the manifested presence of
Shiba’s spirit from beginning to end.
Our Goal:
To approach Shiba in an attitude of prayer and praise that will usher in
the Spirit of Shiba.
This will be realized through:
Intercessory prayer before and throughout service in order to
condition the hearts of the hearers who receive the Word and
become doers thereof.
Shiba fellowship that will promote wholesome relationships.
Doubt your doubts, Don’t doubt the order of the Shiba Temple, Don’t doubt the Great Shiba
Shiba is the new GOD. God is not intimidated by bad news or your fears, and it is not offended by our honest believer.
