Dino.Exchange is an automated market-making (AMM) decentralized exchange (DEX) running on Binance Smart Chain with a lot of features that let you earn tokens by yield farming or playing games on our platform. We want to create an environment where people can do yield farming with sustainably high APR. Some of the Dino Exchange features include:

1. Trade

DinoExchange uses an automated market maker (AMM) model - allows digital assets to be traded without permission and automatically by using liquidity pools instead of a traditional market of buyers and sellers.

2. Farm

Liquidity mining is the best way to make passive income. Liquidity pools are very important for decentralized exchanges and this is exactly one of the key advantages you will have with Dino. With Dino, users can do liquidity mining in selected pools so that they can enjoy passive income. While someone provides liquidity for the designated pool he/she earns a Dino token as a reward

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

DinoToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/DinoToken.sol#219-237) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/DinoToken.sol#229)
Don't use strict equality to determine if an account has enough Ether or tokens.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

DinoToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/DinoToken.sol#85-126) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,DINO::delegateBySig: signature expired) (contracts/DinoToken.sol#124)
Avoid relying on block.timestamp.

DinoToken.getChainId() (contracts/DinoToken.sol#244-248) uses assembly

Pragma version>=0.6.0<0.8.0 (@openzeppelin/contracts/utils/Context.sol#3) is too complex
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

DinoToken.constructor() (contracts/DinoToken.sol#45-48) uses literals with too many digits:
- _mint(msg.sender,uint256(200000000) * uint256(10) ** decimals()) (contracts/DinoToken.sol#47)
Use: Ether suffix, Time suffix, or The scientific notation

decreaseAllowance(address,uint256) should be declared external:
- ERC20.decreaseAllowance(address,uint256) (@openzeppelin/contracts/token/ERC20/ERC20.sol#189-192)
Use the external attribute for functions never called from the contract.
