Defiskeletons is a utility project in DeFi category on binance smart chain.
The project launched on 12th of may 2022 with the goal to develop useful decentralized applications to crypto traders.
May it be beginner, rookie or pro. The dashboard allready offers contract analyzer, non custodial wallet, swap, watchlist, staking platform.
Skeleton wallet available on google playstore.
The development running continously to build a full ecosystem before the team launch the main utility, the skeleton blockchain.
Defiskeletons.swapAndSendToFee(uint256) (#1007-1015) sends eth to arbitrary user
Dangerous calls:
- developmentAddress.transfer(newBalance) (#1013)
Defiskeletons.addLiquidity(uint256,uint256) (#1033-1044) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1036-1043)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Token is flagged by TokenSniffer due to presence of exploit in contract code
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Defiskeletons.withdrawToken(uint256) (#1088-1094) ignores return value by tokenContract.transfer(msg.sender,balance) (#1093)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
