* 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}.

*
* A truly, first of it's kind, anti-inflation, deflationary token.
*
* Our world is experiencing the worst inflation of it's kind in it's history. In order to combat
* and bring some relief to people's lives, we created a unique DEFLATION mechanism that will
* literally increase the value of your tokens with EVERY transaction.
*
* Our tokenomics are based on a revolutionary TRUE deflationary mechanism.
* If you buy 1000 tokens, a 10% tax sends 70 tokens to the contract, and the other 30 tokens
* (3%) are nuked.. Those 30 tokens are subtracted from the TOTAL supply of the $DEFLATION.
* This is DIFFERENT than a typical burn, that would send those tokens to a DEAD address.
* Instead of locking that portion of the liquidity pool in the dead address, the tokens are
* NUKED, deleted, gone, zipped, no longer exist. That means the remainder of the token
* supply, has now had it’s value INCREASE, as just the tokens are nuked, not the actual
* liquidity. Your tokens are now WORTH MORE ETH!
*
* This is the ultimate anti-inflation system.
*
* Join us: https://t.me/Deflation_Token
*
* 12% Tax
* - BUYS: 9% to Marketing, 3% NUKED from SUPPLY
* - SELLS: 3% Marketing, 9% NUKED from SUPPLY

*
* Using this library instead of the unchecked operations eliminates an entire

*
* 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}.

Once upon a time there was an old mother pig who had three little pigs and not enough food to feed them. So when they were old enough, she sent them out into the world to seek their fortunes.
The first little pig was very lazy. He didn't want to work at all and he built his house out of straw. The second little pig worked a little bit harder but he was somewhat lazy too and he built his house out of sticks. Then, they sang and danced and played together the rest of the day.
The third little pig worked hard all day and built his house with bricks. It was a sturdy house complete with a fine fireplace and chimney. It looked like it could withstand the strongest winds.
The next day, a wolf happened to pass by the lane where the three little pigs lived; and he saw the straw house, and he smelled the pig inside. He thought the pig would make a mighty fine meal and his mouth began to water.
So he knocked on the door and said:
Little pig! Little pig!
Let me in! Let me in!
But the little pig saw the wolf's big paws through the keyhole, so he answered back:
No! No! No!
Not by the hairs on my chinny chin chin!
Three Little Pigs straw house
Then the wolf showed his teeth and said:
Then I'll huff
and I'll puff
and I'll blow your house down.
So he huffed and he puffed and he blew the house down! The wolf opened his jaws very wide and bit down as hard as he could, but the first little pig escaped and ran away to hide with the second little pig.
The wolf continued down the lane and he passed by the second house made of sticks; and he saw the house, and he smelled the pigs inside, and his mouth began to water as he thought about the fine dinner they would make.
So he knocked on the door and said:
Little pigs! Little pigs!
Let me in! Let me in!
But the little pigs saw the wolf's pointy ears through the keyhole, so they answered back:
No! No! No!
Not by the hairs on our chinny chin chin!
So the wolf showed his teeth and said:
Then I'll huff
and I'll puff
and I'll blow your house down!
So he huffed and he puffed and he blew the house down! The wolf was greedy and he tried to catch both pigs at once, but he was too greedy and got neither! His big jaws clamped down on nothing but air and the two little pigs scrambled away as fast as their little hooves would carry them.
The wolf chased them down the lane and he almost caught them. But they made it to the brick house and slammed the door closed before the wolf could catch them. The three little pigs they were very frightened, they knew the wolf wanted to eat them. And that was very, very true. The wolf hadn't eaten all day and he had worked up a large appetite chasing the pigs around and now he could smell all three of them inside and he knew that the three little pigs would make a lovely feast.
So the wolf knocked on the door and said:
Little pigs! Little pigs!
Let me in! Let me in!
But the little pigs saw the wolf's narrow eyes through the keyhole, so they answered back:
No! No! No!
Not by the hairs on our chinny chin chin!
So the wolf showed his teeth and said:
Then I'll huff
and I'll puff
and I'll blow your house down.
Well! he huffed and he puffed. He puffed and he huffed. And he huffed, huffed, and he puffed, puffed; but he could not blow the house down. At last, he was so out of breath that he couldn't huff and he couldn't puff anymore. So he stopped to rest and thought a bit.
But this was too much. The wolf danced about with rage and swore he would come down the chimney and eat up the little pig for his supper. But while he was climbing on to the roof the little pig made up a blazing fire and put on a big pot full of water to boil. Then, just as the wolf was coming down the chimney, the little piggy pulled off the lid, and plop! in fell the wolf into the scalding water.
So the little piggy put on the cover again, boiled the wolf up, and the three little pigs ate him for supper.

About WAZIR farm
Yield farming can offer high interest rates, but it is becoming almost impossible for smaller farmers to access.
Tracking & responding to yield farming opportunities can be a full-time job.
Gas costs are increasing, moving in-between farming opportunities is becoming prohibitively expensive.
Wazir Farm addresses this by deploying strategies to move assets between different real-time yield farming opportunities, providing real-time WZR Farmers with funds & insurance as well as maximizing Digital assets & Farm Animal/Crop yield.
Who is a WZR stakeholder?
Any wallet that has staked WZF and harvested WZR , claims & locks it without withdrawing it out of the FARM DeFi platform is stakeholder and is eligible for rewards and voting consensus. (The locked amount is what determines the consensus voting and reward ratio)
HOW TO ACQUIRE PFARM?
Participate in Initial Liquidity Pool Offer by a direct transfer of ETH to Reserve wallet address & get WZR.
Stake WZF tokens & harvest WZR tokens with APY of 4000% plus.
Swap WZR with any supported cryptocurrency on UniSwap, 1inch & Balancer and any swap WZR is listed in future.
Buy from exchanges where WZR is listed… Aside UniSwap and other DEX swaps, we intend to later list on centralized exchanges like; HotBit, Mercatox, P2PB2B, FinexBox, IndoEx & decentralized exchanges like; EtherFlyer, BitCratic, AfroDex and any exchange that lists WZR in future.
2021- the Year of the Metal Ox — is upon us, and it’s time to re-evaluate how the message of Wazir Farm is being delivered.
Yield farming has exploded in popularity over the last few months, but despite this, it’s still a relatively small niche in the wider cryptosphere. The concepts and processes that enable high APYs are complex and murky, so it’s not always easy for newcomers (or even old-hands) to understand what’s going on.
To help with our goal of making yield farming easy and accessible, we are asking our community to come up with a range of marketing materials that will help explain in a clear and concise manner how Wazir Farm works.
We value creativity, clarity and quality!
Things we are particularly interested in are:
Explainer Videos — short videos that explain how WZR works and why it is an important piece of the defi puzzle.
Some ideas to get you started:
• Noob tutorials explaining how to interact with the site , how to deposit , what is APY/APR etc.
• What is Wazir Farm
• Why farm at Wazir Farm?
Gabriel Haines put out a nice video a few months ago, but now it’s a little outdated (defi moves fast), so we need something fresh.
Infographics + Visuals — visual explanations of different process
Things we would like to see:
• Explanations for the main features of WZR
• How profit share works (inc. compounding explanation)
• How different strategies work
• How emissions work
• Timelock feature
• Do Hard Work
• P/E ratio (with comparison where applicable to other projects?)
Gabriel Haines strikes again!
Nice one Grimbles!
The creation of top-notch informative material forms Part 1 of the marketing contest. Once this stage has concluded, we will run Part 2, which involves spreading the knowledge to all corners of the cryptosphere!
We welcome and encourage organic marketing efforts spearheaded by our community of hard-working yield farmers. So if you have solid defi knowledge, understand how WZR works, and can communicate this effectively, you will be rewarded for your efforts.
Part 1 Prizes (paid in FARM tokens)

How to Enter?
Simply post a link to your entry on Twitter, using the hashtag WZRinfo AND tag WZR_farm + WZRfarm
If you have any questions, or perhaps are looking for someone to help with design aspects, then we recommend visiting the WZR website, asking around, and maybe even teaming up with farmers who can compliment your skillset. It’s a very friendly place, with lots of big brains and creative individuals lurking.
We’re looking forward to seeing what y’all come up with!

/**
* @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.

SlamDunk tama is the newest hidden sixth man of the Shohoku basketball team, it is Shohoku’s secret weapon and the essential member of the team. However, SlamDunk tama is largely unknown. This is because tama is so small, frail, unnoticeable, distressingly slow, and easy to miss. SlamDunk Tama has repeatedly made use of his “disadvantage” to create countless miracles for the Shohoku team. It is time to reveal the true hero behind the Shohoku’s basketball team and give him a round of applause.
