* @dev Implementation of the {IERC20} interface.

* 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}.

// 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

/*
RocketV1 - is an opportunity for you to multiply your capital at times.
After the start of trading, as soon as the capitalization is 30 ETH,
we make the coin liquidity lock by 85% (so that 15% of the capitalization is given for sale).
Thus, we will go to the accumulation of investors and the growth of prices.
RocketV2 - After the results of our first launch version, our developers will complete
this version and we will transfer all assets multiplied by 2 to this version.
In this version, everyone who keeps our coin gets 20% reflected from the sale of EACH COIN.
There will be many interesting things - stay with us!
ANTIBot = ON;

/**
🦅 EagleTama 🦅
We are a proud community, one that believes in giving back, and supporting the men and women that fight for a greater cause.
The Bald Eagle is our logo and we stand by that and everything it means for Americans.
The bald eagle became a national symbol way back in 1782.
It was chosen because it represents strength, courage, and freedom.
As a community we will embody these traits as we build a strong family that gives back to those that fought for us.
We plan to use a portion of our tax funds to help charities for the true heroes in our nation, and give back to those who gave it all for us.
We are strong, we are courageous, and we are FREE, we are EagleTama! 🦅 🦅

>> RecycleSWAP Project <<
APRIL 8, 2022
https://recycleswap.net
Initial Supply: 369,888,369,888 RCX
NAME: RecycleSwap
Symbol: RCX
RecycleSWAP (RCX) Project is a recycling solution.
The mechanism will authorize the dead coin and token
holders, to transfer their coins to the RecycleSWAP and
get its tradable coin instead. This will be at restored
value to individual holders who can sell, trade, stake,
liquidate tokens into pools, or circulate their RecycleSWAP
tokens in to the market, and the recycling of project assets
back into the community.
Regarding to the conceptual description of recycling, and
its multifunction methodologies, it is clear that the main
reason of RecycleSWAP Project is economics and the potential
behind its recycleing strategy, considering the technical
requirements it's supposed to fullfil. The RecycleSWAP is
going to perform an economic task that no other asset could
carry out since the birth of Bitcoin.
RecycleSWAP tokens have potential to restore a portion of
the value from other currencies that were reduced because
of lack of the demand, or lost by a rug pull from its
developers or large holders.
Proposed Solution
-----------------
1. Revaluation of dead coin and tokens.
2. Set up a system to restore and transfer this trapped value
in a user-friendly platform.
3. RecycleSWAP Token is a convertible token to transferable
real coin.
4. RecycleSWAP Token Holders can trade their valueless tokens
and coins into Bitcoin, Ethereum, Solano, and other leading
cryptocurrencies will be listed @ RCX Official Website.
5. Unifying of failed and dead coin holders, will permit the
RecycleSWAP Project to clean up the market, and effectively
eliminate the remaining coins to retain their value.
6. RecycleSWAP is the fast and effective way to reform and
rehabilitate the value of the market.
7. RecycleSWAP holders will have an opportunity to reinvest
their regenerated tokens to tradable cryptocurrency projects.
8. RecycleSWAP aims to implement and integrate projects, with
the power of its holders.
Tokenomics
----------
10% First stage ICO
30% Add Liquidity to the market
25% R&D
30% Reserve in contract (Control value of coin)
5% Reserve for the future partners and exchangers
At this point, it should be clear to any holder that listing
RecycleSWAP on exchanges is a critical element in the success
of this phase of the RecycleSWAP project. Without listing,
RecycleSWAP cannot offer a proper gateway to our communities
in order to release value of their dead tokens and coins, into
the market.
Although there are no guarantees that any cryptocurrency or
token will ever get listed on any exchange, the RecycleSWAP
team has been holding talks with various exchanges to list
RecycleSWAP (RCX) token once it enters the market.

* 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

/*
* Lobby contract to update our tokenomics.
*
* This contract is meant to be used as the charity wallet on
* the base Lobby contract.
* Since the original contract relies on transfer() to send the ETH,
* we can't have this contract automatically forward the funds to wallets
* as the gas fees are higher than what transfer() supports.
* We are therefore introducing a public function which can be called to trigger
* the sending of funds to charity and marketing.
*
* Visit https://lobbytoken.io for more details.
