MetaWeb3Pad.claimStuckTokens(address) (#533-542) sends eth to arbitrary user
Dangerous calls:
- address(msg.sender).transfer(address(this).balance) (#536)
MetaWeb3Pad.sendBNB(address,uint256) (#548-553) sends eth to arbitrary user
Dangerous calls:
- (success) = recipient.call{value: amount}() (#551)

MetaWeb3Pad.claimStuckTokens(address) (#533-542) ignores return value by ERC20token.transfer(msg.sender,balance) (#541)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)


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.


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Pragma version0.8.15 (#10) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.15 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.
