white paper

Ethernal is a utility ecosystem that provides rewards in any top coins you want (e.g. ETH, BTC, BNB, SHIB) simply by holding, no need to stake or farm.

A community-driven DeFi Token built on the Binance Smart Chain with an innovative reflections functionality and a focus on continuous, sustainable growth. Ethernal's main objective is to offer as much value as possible to its users through added utility.

The Ethernal project seeks to build upon famous reflection tokens such as Safemoon and
EverGrow by adding an innovative functionality which allows users to claim rewards in up to 6 concurrent tokens of their choosing. In order to guarantee continuous usage, rewards, and valuation, the project team aims to launch new functionalities and marketing efforts regularly.

EthernalFinanceII.SendBNBfromContract(uint256,address) (#1202-1207) sends eth to arbitrary user
Dangerous calls:
- (success) = receiver.call{value: amountBNB}(new bytes(0)) (#1204)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

EthernalFinanceII.random(uint256) (#1137-1143) uses a weak PRNG: "randomnumber = uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,msg.sender,nonce))) % range (#1139)"
Do not use block.timestamp, now or blockhash as a source of randomness

EthernalFinanceII.RewardTokenoftheWeek (#397) is never initialized. It is used in:

Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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

EthernalFinanceII._PayTeam() (#681-708) uses a dangerous strict equality:
- SendBNBfromContract(MarketingBNB,MarketingWallet) == true (#683)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

EthernalFinanceII.ClaimRewards(address) (#1771-1874) performs a multiplication on the result of a division:
-slicevalue = amountBNB / 100 (#1836)
-BNBslice = slicevalue * percslice (#1845)
Consider ordering multiplication before division.

EthernalFinanceII.doBuyback() (#1940-1974) uses timestamp for comparisons
Dangerous comparisons:

- (success,data) = routerAddress.call(abi.encodeWithSelector(0x18cbafe5,tokenamount,0,path,Contract,block.timestamp)) (#1329-1337)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
