CCF [Cross Chain Farming] Token
About CCF
Listings
Website
The first cross-chain Farming as a Service (FaaS) DAO on Binance Smart Chain. Our aim is to optimize the power of farming across all chains, offering simple and low fee access to DeFi 3.0 for everyone. We farm for you, and use reflections and buy-backs to benefit holders, creating sustainable long term price action. In addition, we are the first FaaS DAO to offer additional services including decentralized token launch, listings and on-chain and off-chain security audits Funds from all these services will also be used for buy-backs, farming, etc. to support the CCF token.

CrossChain.sendETHToTeam(uint256) (#921-924) sends eth to arbitrary user
Dangerous calls:
- _CCFWalletAddress.transfer(amount.div(2)) (#922)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.
CrossChain._approve(address,address,uint256).owner (#853) shadows:
- Ownable.owner() (#383-385) (function)
Rename the local variables that shadow another component.
Additional information: link
CrossChain._setMaxTxAmount(uint256) (#1082-1085) should emit an event for:
- _maxTxAmount = maxTxAmount (#1084)
Emit an event for critical parameter changes.
Additional information: link
CrossChain._setCCFWallet(address).CCFWalletAddress (#1078) lacks a zero-check on :
- _CCFWalletAddress = CCFWalletAddress (#1079)
Check that the address is not zero.

Ownable.unlock() (#430-435) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#432)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#340-361) uses assembly
- INLINE ASM (#353-356)
Do not use evm assembly.
Additional information: link
SafeMath.mod(uint256,uint256,string) (#223-226) is never used and should be removed
Remove unused functions.
Additional information: link
CrossChain._previousTeamFee (#666) is set pre-construction with a non-constant function or state variable:
- _teamFee
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.
Additional information: link
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#340-361):
- (success,returndata) = target.call{value: weiValue}(data) (#344)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
Additional information: link
Variable CrossChain._marketingWalletAddress (#669) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#10)" inContext (#4-13)

Variable CrossChain._transferToExcluded(address,address,uint256).rTransferAmount (#972) is too similar to CrossChain._transferStandard(address,address,uint256).tTransferAmount (#963)
Prevent variables from having similar names.
Additional information: link
CrossChain.slitherConstructorVariables() (#641-1087) uses literals with too many digits:
- _maxTxAmount = 100000000000000e9 (#677)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
CrossChain._tTotal (#655) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
_getETHBalance() should be declared external:
- CrossChain._getETHBalance() (#1064-1066)
Use the external attribute for functions never called from the contract.
