white paper

Mdex is an automatic market-making decentralized exchange based on the concept of fund pools. It is similar in function to some DEXs on the market, but on this basis, it proposes and implements a dual-chain DEX model based on the Huobi Eco Chain and Ethereum . It combines the advantages of the low transaction fees of the Huobi Eco Chain and the prosperity of the Ethereum ecosystem, and supports the dual mining mechanism of liquidity and transactions.

Token seems to be legit.

DelegateERC20._writeCheckpoint(address,uint32,uint256,uint256) (#1232-1250) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1242)
Don't use strict equality to determine if an account has enough Ether or tokens.

DelegateERC20.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#1096-1137) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,MdxToken::delegateBySig: signature expired) (#1135)
Avoid relying on block.timestamp.
