white paper

XPRO is a token which created for communities that aim to play an active role in the crypto ecosystem in order to make Web3 more widespread all over the world. It is a project dedicated to the formation of a decentralized internet and financial model of its infrastructure by taking place in the Web3 ecosystem.

It was created by the developer community on BNB Chain which one of the world's largest blockchain-based operating systems, on June 1, 2022. When XPRO was created, the first step was taken to ensure that the contract and liquidity access were thrown into the dead wallet and fully in line with the Web3 vision. Aiming to be one of the cornerstones of decentralized finance, XPRO is a community project that aims to provide decentralized applications and solutions.

XPRO._previousDevelopmentFee (contracts/ProjectX.sol#401) is set pre-construction with a non-constant function or state variable:
- _developmentFee
XPRO._rTotal (contracts/ProjectX.sol#390) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
XPRO._previousLiquidityFee (contracts/ProjectX.sol#404) is set pre-construction with a non-constant function or state variable:
