The VPEX is the reliable and secure exchange for crypto assets trading based on the blockchain with multi future technologies. This makes all operations within the exchange as transparent and high security as possible. VPEX provides people with all necessary tools for professional trading and the fastest transaction speed processing.
Some special on Vpex Exchange: • Secure – Reliable – Professional • The more you hold, the more you gain (Holder earn 2%, Liquidity 2% from each sale VPX) • 100% Fair for All
The vision for Vpex is to go beyond a simple cryptocurrency exchange and act as a full-featured ecosystem that offers its users the opportunity to trade crypto assets on a fully-fledged, transparent, and secure financial platform.
The full components of the ecosystem will include:
VPEX Blockchain Trading Platform for the trading, purchase, sale and exchange of custom tokens and cryptocurrencies of different blockchain, crypto-related projects.
Ecosystem in future: Vpex P2P, Vpex Stake, Vpex wallet, Vpex Gaming, Vpex Social...
Filter quality projects: to promote quality and encourage user engagement, Vpex will institute a rating system for blockchain-crypto-related projects based on different important criteria.
Vpex Startup Incubator: support to startups in realizing their business ideas with advice on capital raise, technical infrastructure development, networking...
VPEX will be a one-of-a-kind system that bridges the gap between crypto trading and startup growth and promotion with a single platform. Vpex team is now giving the global crypto community the opportunity to participate in the further development of the platform. Such cooperation can produce benefits to everyone involved in the public token sale.
VPEX will initially launch in Australia with a subsequent expansion to other countries (Saint Vencent, Germany, UK...). This gives early investors a unique opportunity to enter a new startup that is backed by industry best practices and a regulatory framework early on.

Ownable.unlock() (#435-440) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#437)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#345-366) uses assembly
- INLINE ASM (#358-361)
Do not use evm assembly.
Additional information: link
SafeMath.mod(uint256,uint256,string) (#217-220) is never used and should be removed
Remove unused functions.
Additional information: link
VPEX._previousLiquidityFee (#671) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#345-366):
- (success,returndata) = target.call{value: weiValue}(data) (#349)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
Additional information: link
Variable VPEX._maxTxAmount (#679) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#229)" inContext (#223-232)
Remove redundant statements if they congest code but offer no value.
Additional information: link
Variable VPEX._transferFromExcluded(address,address,uint256).rTransferAmount (#1154) is too similar to VPEX._getValues(uint256).tTransferAmount (#926)
Prevent variables from having similar names.
Additional information: link
VPEX.numTokensSellToAddToLiquidity (#680) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
isExcludedFromFee(address) should be declared external:
- VPEX.isExcludedFromFee(address) (#998-1000)
Use the external attribute for functions never called from the contract.
