SPF [SpaceFi] Token

SPACEFI.swapBack() (#355-398) sends eth to arbitrary user
Dangerous calls:
- address(marketingFeeReceiver).transfer(amountETHMarketing) (#383)
- address(teamFeeReceiver).transfer(amountETHteam) (#384)
- address(pipdFeeReceiver).transfer(amountETHPiPd) (#385)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

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

SPACEFI.takeFee(address,uint256,address) (#292-320) performs a multiplication on the result of a division:
-feeAmount = amount.mul(totalFee).mul(multiplier).div(feeDenominator * 100) (#305)
-utilityTokens = feeAmount.mul(utilityFee).div(totalFee) (#306)
Consider ordering multiplication before division.

SPACEFI.totalFee (#171) is set pre-construction with a non-constant function or state variable:
- marketingFee + liquidityFee + teamFee + utilityFee + pipdFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version0.8.12 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.12 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.
