DXB is the utility token that will power the DXBPay ecosystem for all future DeFi products. The DXB token is a specialized cryptocurrency with a plan to encompass multiple technologies like DeFi, merchant payment channels, incentives, and charity.
DXBPay is building a payment model that utilizes cross-chain capabilities to serve the needs of merchants, and offer a safe payment gateway that allows a wider sector of clients to shop online and pay using their crypto currency.
The final product of DXBPay will be adopted by merchants who perform large-scale and high-speed transactions and wish to expand their client's reach by accepting crypto currency as a form of payment without jeopardizing their profits and loosing on transaction fees.
It is a cost effective, fast and safe method for accepting cryptocurrency payments and can be incorporated by anyone.
In such, DXB Pay is building a complete eco-system that truly bridges the crypto universe with the real world.
The token has an intelligent contract that rewards investors in a whole new way, and a smart burning mechanisms.

DXB.addLiquidity(uint256,uint256) (#942-955) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#947-954)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DXB._swap(uint256) (#973-1000) uses a dangerous strict equality:
- _rewardPoolValue == 0 (#993)
Don't use strict equality to determine if an account has enough Ether or tokens.
Additional information: link
Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
DXB._updateUseCaseWallet(address).usecaseWallet (#786) lacks a zero-check on :
- _useCaseFeeWallet = usecaseWallet (#786)
Check that the address is not zero.

DXB._computeFee(uint256) (#961-967) performs a multiplication on the result of a division:

Consider ordering multiplication before division.

DXB._transfer(address,address,uint256) (#824-866) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.
