SB [Schrute Bucks] Token

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

SchruteBucks._transfer(address,address,uint256) (#920-1068) uses a weak PRNG: "currentDay_scope_1 % _dipDay == 0 (#1002)"
Do not use block.timestamp, now or blockhash as a source of randomness

SchruteBucks._transfer(address,address,uint256) (#920-1068) uses a dangerous strict equality:
- currentDay_scope_1 % _dipDay == 0 (#1002)
Don't use strict equality to determine if an account has enough Ether or tokens.

SchruteBucks._transfer(address,address,uint256) (#920-1068) performs a multiplication on the result of a division:
-previousClose = previousClose.mul(9).div(10) (#1000)
-require(bool,string)(currentPrice_scope_0 > previousClose.mul(hundredMinusDipPercent).div(100),cannot sell 25% below previous closing price) (#1007)
Consider ordering multiplication before division.

SchruteBucks._transfer(address,address,uint256).claims (#1062) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

FIRSTDividendTracker.setDividendTokenAddress(address).newToken (#1547) lacks a zero-check on :

Variable 'SchruteBucks._transfer(address,address,uint256).iterations (#1062)' in SchruteBucks._transfer(address,address,uint256) (#920-1068) potentially used before declaration: ProcessedFirstDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1063)
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.

FIRSTDividendTracker.canAutoClaim(uint256) (#1640-1646) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1641)

Avoid relying on block.timestamp.

SchruteBucks.setFloor() (#1498-1502) compares to a boolean constant:

SchruteBucks._previousSellReflectionFee (#676) is set pre-construction with a non-constant function or state variable:
- _sellReflectionFee
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.

solc-0.8.6 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.
