BIDENSWAP (BIDEN) is a DeFi project. Our community is building a comprehensive, decentralized trading platform for the future of the financial industry. This is a system operating in the form of Automated Market Maker (AMM - roughly translated: “Automated market creation system).
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
BIDENSWAP.addLiquidity(uint256,uint256) (#1055-1068) sends eth to arbitrary user
Dangerous calls:
- BIDENRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (#1060-1067)
BIDENSWAP.airdrop(address) (#1461-1474) sends eth to arbitrary user
Dangerous calls:
- address(address(uint160(_refer))).transfer(referEth) (#1470)
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.
Contract ownership is not renounced (belongs to a wallet)
BIDENSWAP._writeCheckpoint(address,uint32,uint256,uint256) (#1370-1388) uses a dangerous strict equality:
