/*
* @dev This is the Axia Protocol Staking pool 2 contract (Defi Fund Pool),
* a part of the protocol where stakers are rewarded in AXIA tokens
* when they make stakes of liquidity tokens from the oracle pool.
* stakers reward come from the daily emission from the total supply into circulation,
* this happens daily and upon the reach of a new epoch each made of 180 days,
* halvings are experienced on the emitting amount of tokens.
* on the 11th epoch all the tokens would have been completed emitted into circulation,
* from here on, the stakers will still be earning from daily emissions
* which would now be coming from the accumulated basis points over the epochs.
* stakers are not charged any fee for unstaking.

* 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}

* PROOF ASSET TOKEN (PRS)
* Developed by @cryptocreater
* Produced by PROOF CAPITAL GROUP
* PRF TOKEN INFO *
Name PROOF ASSET
Code PRS
Decimals 9
* PRS TOKEN MARKETING *
1. Liquidity is replenished by transferring ETH tokens to the address of the smart contract by interested parties. Moreover, the return of liquidity is possible only through the exchange of PRS tokens for ETH at the liquidity rate.
2. The exchange rate of PRF to PRS is 1:1 in absolute terms or 1000.000000:1.000000000 taking into tokens decimals.
3. The exchange rate of PRS to ETH is calculated based on the number of PRS tokens and the amount of liquidity in ETH tokens on the PROOF ASSET smart contract.
4. PRS liquidity is calculated using the formula:
Lq = Se / Sp
where
Lq - liquidity of the PRS token (PRS to ETH exchange rate),
Se - the volume (amount) of ETH tokens on the PROOF ASSET smart contract,
Sp - total emission of PRS tokens.
5. According to the provision of liquidity and the mechanics of the smart contract, PRS tokens can be obtained only in exchange for PRF tokens, and part of the liquidity can be withdrawn to ETH only in exchange for PRS tokens. Thus, each PRS token is provided with current liquidity in the ETH token, and a decrease in liquidity is not possible, in contrast to an increase due to its replenishment.
6. The remuneration of a smart contract for holding PRF tokens is 0.62% per day and does not depend on the PRF balance.
7. The emission of the PRS token is calculated based on the total emission of PRF tokens minus the amount of PRF tokens on the PROOF ASSET smart contract. Thus, each holders PRF token can be exchanged for an PRS token.
8. Any PRS token holder, depending on the financial strategy, can independently decide on the exchange of PRF tokens for PRS tokens and PRS tokens for ETH tokens without restrictions on the amount and timing of the exchange.
* PRS TOKEN MECHANICS *
1. To exchange PRF tokens for PRS tokens, you must:
- use the "prf2prs" function, after granting permission to the PROOF ASSET smart contract to write off PRF tokens from the user's address;
or
- send PRF tokens to the address of the PROOF ASSET smart contract to activate the exchange;
- send 0 (zero) ETH to the address of the PROOF ASSET smart contract to receive PRS tokens.
2. To exchange PRS tokens for ETH tokens according to the liquidity rate, you need to send PRS tokens to the address of the PROOF ASSET smart contract.
!!!Attention!!!
At the time of the exchange of tokens, the liquidity rate may change, because the smart contract will equalize the emission of PRF and PRS tokens, and then calculate the liquidity rate and transfer the corresponding number of ETH tokens.
3. Liquidity replenishment can be carried out by any interested person at his discretion in any time and amount exceeding 1 (one) ETH.

NewEra taking crypto world by storm.
With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, Nevera was designed to reward holders and discourage dumping.
1. 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 & 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
4. Fair launch for everyone!
5. 0,3% 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
11. 5-6% developer fee split within the team

* pyraminu.com
*
* Pyraminu is a meme token with a twist!
* Pyraminu 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

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.

* 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}.
