MysteriousDeFi.contractSwap(uint256) (#669-706) sends eth to arbitrary user
Dangerous calls:

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
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.
Variable 'MysteriousDeFi._finalizeTransfer(address,address,uint256,bool,bool,bool,bool).check (#604)' in MysteriousDeFi._finalizeTransfer(address,address,uint256,bool,bool,bool,bool) (#594-626) potentially used before declaration: checked = check (#605)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
