All Crypto Lending
Payship is a major step forward in crypto lending: Deposit any ERC20 token.
Use any ERC20 token as collateral. Earn interest on any deposit.
Borrow any ERC20 token.
Stake PSHP to earn portion of Payship income.
Vote with PSHP on Payship future.
Lending Economics
Payship is a major step forward in lending economics: Collateral factors and interest rates of deposits and borrows are re-calculated once a day based on the performance of the entire Ethereum ERC20 token ecosystem.
Borrower Protection
Payship is a major step forward in borrower protection: Every rate has a 24 hour guarantee through the single re-calculation once a day.
Every borrower found under liquidation after the re-calculation has 24 hours to fix the position before being liquidated on the next re-calculation.
Off-chain Systems Model (refer to the Whitepaper) enables automatic borrower protection from liqudiation in case of a price increase on borrowed asset or price deacrese on collateral:
in case of a borrower going below the liquidation treshold, Payship can automatically and for free repay a portion of the loan using the collateral.

* Anti-dump Tokenomics where sell tax will be proportional to price impact
*
* 10% of all taxes collected will be redistributed to reward the holders

* Early snipers/movers advantage will be limited.
*
* Contract will not be renounced as we need it for the game as well as CEX listings,

/**
* @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 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

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

Inu Women’s Day (IWD)
Happy International Women's Day 2021! Inu Women’s day celebrates gender equality today and recognises the social, economic, cultural and political achievements of women. This token honours women's achievements and raises awareness about women's equality at the same time.
Despite accounting for half the world’s population, women made up more than two-thirds of the world’s illiterate people, an estimated 60 percent of chronically hungry and held just 28 percent of managerial positions globally in 2019 (almost the same as in 1995). Historically, women have been valued as less than their male counterparts.
Allow us to quote the respectable Malala Yousafzai “If we want to live in a more equal future, leaders must prioritise quality education. Educating young women can also help to prevent wars, mitigate the effects of climate change and make economics grow”
The purpose of this token not only celebrates the progress of women’s rights in this hundred years but also reminds mankind that our war against inequality isn’t over and still far from success.
Tokenomics:
Max supply: 10 Billion
Initial LP: 3 / 4
Max buy: 2%
Tax: 12%
4% LP
3% Reflection
3% Marketing and Dev
2% Donation for women’s education

*
* 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}.

Pizzeria DAO
We are going to buy a Pizzeria and run our own Pizzeria afterwards!
This is the governance token of Pizzeria DAO to have a stake
in our Pizzeria and to vote on how to run the Pizzeria
and on what pizzas and other food/beverages we should offer,
add, or take down from the menu.
All profits from the restaurants will be shared with all token
holders proportionally, or will be used to invest in the
Pizzeria, depending on the governance vote.

*
* 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}.
