SCOPX Token (SCX) is a decentralized community driven and fair launch Defi token.
SCOPXToken usecases are to develop Daps Website (scopxtoken.nft) the Decentralized marketplace with the ability to minting NFT, to buy and sell arts, music, ideas and services.
Online retail marketplace on blockchain platform. Scopxtoken will be use as utility token for all this services.
SCOPXTOKEN.addLiquidity(uint256,uint256) (#1214-1227) sends eth to arbitrary user
Dangerous calls:
- pancakeSwapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1219-1226)
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.

solc-0.8.5 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
