Quaternion is a NFT full-stack B2B B2C service provider in the blockchain world. QTN is a ERC20 token with zero-fees and a RFI protocol with 10.101% reflections.
The project was hacked and 2.546 WETH was taken. QTN token has an inflation mechanism: all QTN holders' balanceOf will increase for each QTN's sale in Uniswap. However, the QTN's developer uses “from == UniswapPair” to judge if there is a QTN's sale. The incorrect condition is the root cause of this attack.
