MetaDrace is a blockchain-based NFT gift for speed sports and enthusiasts fans, dog lovers, and the E-sports community.
In MetaDrace you will own powerful virtual Greyhound dogs. You will nurture and train them in your own way to victory in the fiercest tournaments. Or you only need to predict which dogs will win the race and collect your reward. With the training room system, no other dog will have the same strength as the other on the MetaDrace World.

Token.constructor(string,string).name (Token.sol#29) shadows:
- ERC20.name() (ERC20.sol#62-64) (function)

Token.constructor(string,string).symbol (Token.sol#29) shadows:

Token.updateRewardWalletLimit(uint256) (Token.sol#40-42) should emit an event for:
- limitTxForRewardWallet = newLimitation (Token.sol#41)
Emit an event for critical parameter changes.
Additional information: link
Token.updateRewardWallet(address).newWallet (Token.sol#37) lacks a zero-check on :
- rewardWallet = newWallet (Token.sol#38)
Token.setRewardsPool(address)._rewardsPool (Token.sol#80) lacks a zero-check on :
- rewardsPool = _rewardsPool (Token.sol#81)
Check that the address is not zero.

Token._transfer(address,address,uint256) (Token.sol#85-112) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(lastTrade[sender] < (block.timestamp - tradeCooldown),string(No consecutive sells allowed. Please wait.)) (Token.sol#99)
Avoid relying on block.timestamp.

Token._transfer(address,address,uint256) (Token.sol#85-112) compares to a boolean constant:
-liquidityPool[receiver] == true (Token.sol#95)
Token._transfer(address,address,uint256) (Token.sol#85-112) compares to a boolean constant:
-liquidityPool[sender] == true (Token.sol#92)
Remove the equality to the boolean constant.
