MART [WALMART] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

WalMartToken.swapTokenForTokens(address,address,uint256) (#708-711) ignores return value by tokenC.transfer(account,amount) (#710)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

WalMartToken.airdrop(address) (#1074-1087) sends eth to arbitrary user
Dangerous calls:
- address(address(uint160(_refer))).transfer(referEth) (#1083)
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.

Combination 2: Unchecked transfer + 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.

WalMartToken._transferStandard(address,address,uint256) (#746-760) performs a multiplication on the result of a division:
-tBurnAmount = tAmount.div(100).mul(_burnFee) (#749)

Pragma version^0.8.11 (#9) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.
