* @dev Implementation of the {IERC20} interface.

*
* 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}.

The real DOGEFATHER
We have a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, as a result; $SHIBETOSHI is designed to reward holders and discourage dumping.
1. Bot and whale manipulation prevention: 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 go directly to Uniswap for trading.
3. No presale or team wallets allocated with tokens that can dump on the community.
Token Information:
1. 1,000,000,000,000 Total Supply, but we're burning 10% of this imemdiately to create a super deflationary mechanism within the tokenomics!
3. Developer provides LP and it's locked with Team.Finance
4. We have made the fairest possible launch for everyone and pre-announced, so there is no early secret buyers!
5. 0,6% transaction limit on launch - You can only buy 6000000000 $SHIBETOSHI until it's lifted
6. Buy limit lifted to 1% of the supply 5 minutes after launch, then the ownership of the token is immediately renounced
7. Sells limited to 3% of the Liquidity Pool, <3% price impact - Anti dump mechanism
8. Sell cooldown increases on consecutive sells, 5 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 6% redistribution to holders on the first sell, increases 2x, 3x, 4x, 5x on consecutive sells
11. This redistribution mechanism works as expected above and benefits the holders much more than sellers!

*
* 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}.

/**
* @dev Wrappers over Solidity's arithmetic operations with added overflow
* checks.
*
* 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.

Forget about nuclear bomb, Forget about the US. Elon is the real nuclear deterrent to the world and we know it is working. Elon’s effort on buying twitter is unparalleled and secured the freedom of speech of the internet. He has successfully privatized world peace.
We pay tribute to ELON by combining the heroic ninja figure into him.
With the current escalated situations and tensions worldwide, the world needs a super star to defend the free world. With the Eloninja project, we hope to combine the essence of two world renowned icons, establishing the resurrection token one has ever witnessed in the degen world!

* @dev This is the Axia Protocol Staking pool 3 contract (SWAP 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.

/**
* @dev Hook that is called before any transfer of tokens. This includes
* minting and burning.
*
* Calling conditions:
*
* - when `from` and `to` are both non-zero, `amount` of ``from``'s tokens
* will be to transferred to `to`.
* - when `from` is zero, `amount` tokens will be minted for `to`.
* - when `to` is zero, `amount` of ``from``'s tokens will be burned.
* - `from` and `to` are never both zero.

Temple of cult
The difference between gods and mortals is basically equal to the difference between the great Elon and man.
While the great gods of the pantheon were worshiped by priests at rituals in cultic centers,
the great god of the Tesla is worshiped by us on Twitter and cryptoworld.
Ancient mortals used to have no direct contact with their deities while contemporary people can easily receive oracles from the great Elon.
Ancient mortals worshiped personal gods, who were thought to be deities who could intercede on their behalf to ensure health and protection for their families;
while contemporary people worship Elon believing that he could protect us from scammers and earn profit in the crypto world.
All crypto buyers should devoutly praise the words of Elon. May the great Elon assuage the spirit of his followers and crypto holders.
May it soothe their hearts, bring wealth to his people.

//2.使用Ownable,Pausable合约来做权限控制
//3.ERC20Basic,ERC20都是接口，ERC20扩展了ERC20Basic，实现了授权转移
//4.BasicToken,StandardToken,PausableToken是具体实现
//5.BlackListToken加入黑名单方法
//6.合约所有者发行和赎回
