* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means
* that a supply mechanism has to be added in a derived contract using {_mint}.
* 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}.

"Searching for the wealth of mental battle" According to the end of the puzzle, you will get into the telegraph group and click on the reward distribution website to divide up the huge reward.
The first 200 lucky people who solve the puzzle that we posted on Twitter, please get into the telegrams and submit your erc20 wallet address on the prize distribution site, and claim your reward.
The amount of the reward will be based on the following rules. The earlier you buy, the more portions you get.
The top 10 holders who buy $Seekme will be rewarded with ETH for holding the same value of $Seekme, 11-50 holders will be rewarded with ETH for 70%, 51-100 holders will be rewarded with ETH for 30%, 101-200 holders who buy $Seekme will receive ETH rewards for holding 10% of the value of $Seekme.
Tip: Count only the value of the first buy order. The first 50 $Seekme - buying holders who enter TG within 30 minutes of launch will receive additional rewards. The answer to the puzzle is the telegraph group link.
All information is in the Telegraph group, or check out Twitter for more information

Who and what is PullBack?
PULLBACK is programmed to reward HODLers while increasing in both liquidity and value.
It does this by applying a 10% tax on transactions; 5% goes to HODLers, 5% is auto-locked to liquidity.
FOREVER DEFLATIONARY SUPPLY.
We burned 30% of the total supply after launch, and sent it to a black hole address.
As this address also participates in the protocol, it accumulates more tokens,
thereby effectively removing them from circulation. There is no limit to the burn; the black hole will continue to grow,
increasing the scarcity of PULLBACK.
WHY 30%?
This part makes PULLBACK hyperdeflationary; the burn address accumulates the most coins during tax distribution.
SAFE LIQUIDITY.
LP tokens are burned, & liquidity is locked forever.
OWNERSHIP RENOUNCED.
No one has control over the token contract, so no malicious actions are possible.
Governance
PULLBACK HODLers will have the right to access our governance system - a platform on which HODLers can vote and make future suggestions.
Charity
We are already planning to set up a charity wallet! We will use the accumulated tax to send to a charity that has been chosen by our community. This will be a periodic thing that we do for different charities as a community.
NFT Farm
In the near future, HODLers will also be able to use the PULLBACK token in order to farm NFTs! Partnerships with various artists are already in the works.
PullBack offers an automated solution for reducing the hassle and time spent on performing complex financial operations, while at the same time keeping your assets secure. It’s based on an access-from-anywhere system in which anyone, with only an internet connection, can benefit from the full freedoms of modern finance.
Even though we’re a private company, PullBack is dedicated to embracing community. So your support, feedback and involvement is crucial to our offering a more valuable, seamless experience.
This is just the beginning of a long journey. We invite everyone to imagine, hope and dream of a new reality through decentralized finance.
Introducing the PullBack Token (PLBK)
We are very excited to share more information about the token economy available on PullBack. As expected, PullBack, bringing a new era of automated finance, will introduce a token in our ecosystem. The ticker will be PLBK and we love to call it “PullBacks”.
Please find below a comprehensive list of questions and answers shedding some light on how the token works. Also, a couple of key points:
There is no token sale at all.
The team has no allocation of PLBK.
PLBK has no value, but a buyback will happen. See details below.

*
* 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.
* Michael Low
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

/**
* VANILLA GORILLA - $VILLA
* https://t.me/vanillagorillatoken
* www.vanillagorilla.co
* $VILLA is a token with a twist and have used a similar tokenomics concept as MUSUBI! Check out the Tokenomics!
* No sale limitations, which benefits whales and little fish alike.
* An innovative dynamic reflection tax rate which increases proportionate to the size of the sell.
TOKENOMICS:
* 1,000,000,000,000 TOTAL 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!

Join us on Easter in a $CULT like fashion and search for the original $EGGS in the blockchain.
Periodically throughout the day, search for our social media channels in the code.
Then search our social media channels for more clues to the $EGGS of where the website is,
when no tax hour is, what to Tweet for prizes and more. Will you be able to find all the $EGGS?

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// We derive the sqrtPriceX96 via Maker's own oracles to prevent price manipulation in the pool:
//
// p0 = price of token0 in USD
// p1 = price of token1 in USD
// UNITS_0 = decimals of token0
// UNITS_1 = decimals of token1
//
// token1/token0 = (p0 / 10^UNITS_0) / (p1 / 10^UNITS_1) [Conversion from Maker's price ratio into Uniswap's 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 most tokens to provide something like getUnderlyingBalancesAtPrice(uint160 sqrtPriceX96)
// which will forward our oracle-calculated `sqrtPriceX96` to the Uniswap-provided 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

/**
* @dev Implements an ENS registrar that sells subdomains on behalf of their owners.
*
* Users may register a subdomain by calling `register` with the name of the domain
* they wish to register under, and the label hash of the subdomain they want to
* register. They must also specify the new owner of the domain, and the referrer,
* who is paid an optional finder's fee. The registrar then configures a simple
* default resolver, which resolves `addr` lookups to the new owner, and sets
* the `owner` account as the owner of the subdomain in ENS.
*
* New domains may be added by calling `configureDomain`, then transferring
* ownership in the ENS registry to this contract. Ownership in the contract
* may be transferred using `transfer`, and a domain may be unlisted for sale
* using `unlistDomain`. There is (deliberately) no way to recover ownership
* in ENS once the name is transferred to this registrar.
*
* Critically, this contract does not check two key properties of a listed domain:
*
* - Is the name UTS46 normalised?
* - Is the Deed held by an appropriate custodian contract?
*
* User applications MUST check these two elements for each domain before
* offering them to users for registration.
*
* Applications should additionally check that the domains they are offering to
* register are controlled by this registrar, since calls to `register` will
* fail if this is not the case.

* @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.
