What is DRIVENecosystem?

DRIVENecosystem (or just DRIVEN) is a small start-up that aims to integrate cryptocurrencies into everyday life through the use of smart applications. Our primary goal is to make cryptocurrency as simple to use as FIAT.

Philosophy and vision

Our team is guided by core principles such as honesty, integrity, respect, ambition, and fun. By doing so, we build a strong community with the same values as us through time and with a lot of effort - a community that makes us proud, trusts us, and knows us for who we are.

Our goal is to build a strong DeFi ecosystem where individuals can use cryptocurrency to buy or trade goods and services.

What is DRIVENx?

DRIVENx (DVX) is a BEP20 token released on the Binance Smart Chain Network in August of 2021. Our focus is on bridging the gaps between cryptocurrency and standard FIAT-based business as usual.

DRIVEN’s primary goal is to bridge the needs of everyday businesses from your barber to your baker to your candlestick maker with the crypto ecosystem that enables them to use cryptocurrency for goods and services in a simple and intuitive manner, removing complexity from the current cumbersome process.

What is the mission of the DRIVENx?

We are creating a platform in which businesses can carry out all of their existing transactions with respect to their customer's supply chain, via cryptocurrency.

The platform will enable a business to directly pay or receive funds for goods and/or services without having to convert their cryptocurrency to fiat currency, in turn avoiding costly foreign exchange fees and the associated price fluctuations. They can pay or receive the cryptocurrency of their choosing and transact in a peer-to-peer manner using our service as the intermediary broker for the transactions.

DrivenX.addLiquidity(uint256,uint256) (DrivenX.sol#480-495) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (DrivenX.sol#486-493)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.


Combination 2: Unchecked transfer + 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.

DrivenX._transfer(address,address,uint256) (DrivenX.sol#351-434) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (DrivenX.sol#407)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (DrivenX.sol#411)
Consider ordering multiplication before division.

DrivenX._transfer(address,address,uint256).claims (DrivenX.sol#427) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Variable 'DrivenX._transfer(address,address,uint256).iterations (DrivenX.sol#427)' in DrivenX._transfer(address,address,uint256) (DrivenX.sol#351-434) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (DrivenX.sol#428)
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.
