RARE [Rarety] Token

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

Contract ownership is not renounced (belongs to a wallet)

Reentrancy in RARE.enableTrading() (#340-349):
External calls:

State variables written after the call(s):

Reentrancy in RARE.transferOwner(address) (#176-187):
External calls:

RARE.finalizeTransfer(address,address,uint256,bool).checked (#372) is a local variable never initialized
RARE.finalizeTransfer(address,address,uint256,bool).check (#373) 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.

Additional information: link

RARE.finalizeTransfer(address,address,uint256,bool) (#364-382) ignores return value by antiSnipe.checkUser(from,to,amount) (#373-374)
Ensure that all the return values of the function calls are used.

Additional information: link

RARE.setOperator(address).newOperator (#197) lacks a zero-check on :
- operator = newOperator (#203)
Check that the address is not zero.

Additional information: link

RARE.finalizeTransfer(address,address,uint256,bool) (#364-382) has external calls inside a loop: antiSnipe.checkUser(from,to,amount) (#373-374)
Favor pull over push strategy for external calls.

Additional information: link

Variable 'RARE.finalizeTransfer(address,address,uint256,bool).check (#373)' in RARE.finalizeTransfer(address,address,uint256,bool) (#364-382) potentially used before declaration: checked = check (#374)
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.

Pragma version>=0.6.0<0.9.0 (#4) is too complex
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.

RARE.timeSinceLastPair (#109) is never used in RARE (#101-384)
Remove unused state variables.

RARE.timeSinceLastPair (#109) should be constant
Add the constant attributes to state variables that never change.

transfer(address,uint256) should be declared external:
- RARE.transfer(address,uint256) (#225-228)
getCirculatingSupply() should be declared external:
- RARE.getCirculatingSupply() (#270-272)
enableTrading() should be declared external:
- RARE.enableTrading() (#340-349)
Use the external attribute for functions never called from the contract.
