white paper

The biggest difference between "Super Minesweeper" and Microsoft Minesweeper is that it empowers the game map to make a perfectly replicated decentralized + NFT + P2E + DeFi game for the vast number of cryptocurrency lovers and Minesweeper lovers. The game map that users play is not generated by the system, but a unique game map created by users, uploading the map parameters to the block chain to obtain NFT credentials, Minesweeper starts by referring to the NFT parameters on the chain to obtain the game map. At the same time, the user creates and generates the game map NFT can be stored and traded.

SweepNFT.rand(uint256) (SweepNFT.sol#200-203) uses a weak PRNG: "random % (uint256(4123456).add(len)) (SweepNFT.sol#202)"
Do not use block.timestamp, now or blockhash as a source of randomness

SweepNFT.createNft(uint256,uint256,uint256,uint256[],address,uint256) (SweepNFT.sol#120-193) ignores return value by _Token.transferFrom(msg.sender,idea_address,fee_) (SweepNFT.sol#182)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

SweepNFT.createNft(uint256,uint256,uint256,uint256[],address,uint256) (SweepNFT.sol#120-193) uses a dangerous strict equality:
- lucky == 0 (SweepNFT.sol#175)
Don't use strict equality to determine if an account has enough Ether or tokens.

SweepNFT.createNft(uint256,uint256,uint256,uint256[],address,uint256) (SweepNFT.sol#120-193) contains a tautology or contradiction:
- points_[i] >= w_h || points_[i] < 0 (SweepNFT.sol#153)
Fix the incorrect comparison by changing the value type or the comparison.

Reentrancy in SweepCoinEcologyPool.withdraw() (SweepCoinEcologyPool.sol#231-241):
External calls:
- _Token.transfer(msg.sender,value) (SweepCoinEcologyPool.sol#236)
State variables written after the call(s):
- unwithdrawList[msg.sender] = 0 (SweepCoinEcologyPool.sol#238)
Apply the check-effects-interactions pattern.

SweepCoinMiningPool.canWithdrawalAmount(uint256) (SweepCoinMiningPool.sol#270-287) performs a multiplication on the result of a division:
-_accTokenPerShare = total.div(lpSupply) (SweepCoinMiningPool.sol#280)
-amount = mining.lp.mul(_accTokenPerShare).div(1000).sub(mining.rewardDebt) (SweepCoinMiningPool.sol#283)
Consider ordering multiplication before division.

SweepNFT.createNft(uint256,uint256,uint256,uint256[],address,uint256) (SweepNFT.sol#120-193) ignores return value by _Token.burnToZero(msg.sender,coin) (SweepNFT.sol#185)
Ensure that all the return values of the function calls are used.

SweepNFT.constructor(string,string,address)._symbol (SweepNFT.sol#56) shadows:
- ERC721._symbol (ERC721.sol#60) (state variable)
Rename the local variables that shadow another component.

SweepNFT.setMineRatio(uint256,uint256) (SweepNFT.sol#79-82) should emit an event for:
- min_mine = min_mine_ (SweepNFT.sol#80)
- max_mine = max_mine_ (SweepNFT.sol#81)
Emit an event for critical parameter changes.

SweepNFT.setCoinEcologyPool(address).pool_address (SweepNFT.sol#63) lacks a zero-check on :
- ecologyPoolAddress = pool_address (SweepNFT.sol#65)
Check that the address is not zero.

Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

External calls:
- _Token.transfer(msg.sender,value) (SweepCoinEcologyPool.sol#236)

- totalUnWithdraw = totalUnWithdraw.sub(value) (SweepCoinEcologyPool.sol#240)
- totalWithdraw = totalWithdraw.add(value) (SweepCoinEcologyPool.sol#239)

SweepNFT.createNft(uint256,uint256,uint256,uint256[],address,uint256) (SweepNFT.sol#120-193) uses timestamp for comparisons
Dangerous comparisons:
- lucky == 0 (SweepNFT.sol#175)
- lucky > 5 (SweepNFT.sol#176)
Avoid relying on block.timestamp.

ERC721._checkOnERC721Received(address,address,uint256,bytes) (ERC721.sol#451-472) uses assembly
- INLINE ASM (ERC721.sol#464-466)
Do not use evm assembly.

SweepCoinMiningPool.increasePledge(uint256,uint256) (SweepCoinMiningPool.sol#104-169) compares to a boolean constant:
-require(bool,string)(isStart == true,The ore pool is not opened) (SweepCoinMiningPool.sol#106)
Remove the equality to the boolean constant.

Low level call in Address.sendValue(address,uint256) (Address.sol#12-16):
- (success) = recipient.call{value: amount}() (Address.sol#14)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable SweepNFT.max_mine (SweepNFT.sol#49) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (Context.sol#11)" inContext (Context.sol#5-14)
Remove redundant statements if they congest code but offer no value.

Variable SweepCoin._totalSupply (SweepCoin.sol#30) is too similar to SweepCoin.constructor(uint256,string,uint256,string).totalSupply_ (SweepCoin.sol#40)
Prevent variables from having similar names.

getTokenData(uint256) should be declared external:
- SweepNFT.getTokenData(uint256) (SweepNFT.sol#196-198)
Use the external attribute for functions never called from the contract.
