DRV [Dragon Verse] Token

DragonVerse.withdrawTokens(address,address,uint256) (#892-899) ignores return value by IERC20(tokenAddress).transfer(to,amount) (#897)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

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.
