white paper

French Connection Finance (FCF) is a cryptocurrency that runs on the Binance Smart Chain network. FCF is developing the world’s first credit card to cryptocurrency payment gateway. This will allow anyone to purchase a product or service in cryptocurrency simply by using their existing credit card.

By investing in $FCF tokens, you will earn a passive income simply by holding the token. This is accomplished through an innovative dividend program which automatically rewards holders with a 5 % BNB reflection every 24 hours.

Dividends are generated by taxing each purchase, sale, or transfer of FCF, in addition to any purchase made through the payment gateway.

FCF is also launching an NFT collection, developing an advanced DeFi wallet, and is building FCF World Connection - a classified and revolutionary DApp.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

FCF.addLiquidity(uint256,uint256) (#2174-2186) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#2177-2184)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SafeToken.withdraw(address,uint256) (#1731-1734) ignores return value by IERC20(_token).transfer(safeManager,_amount) (#1733)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)

Pragma version^0.8.0 (#3) allows old versions
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.
