Gallant Token is a decentralized finance smart contract built on the Binance Smart Chain; a community of people from across the world; and a brand. Our core team is fully doxxed and our goal is to create medieval-inspired games & NFTs that integrate blockchain technology across different platforms.
Gallant.sendToWallet(address,uint256) (#919-921) sends eth to arbitrary user
Dangerous calls:
- wallet.transfer(amount) (#920)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
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.
SafeMath.div(uint256,uint256,string) (#61-66) is never used and should be removed
Remove unused functions.

Gallant._previousLiquidityAndPromoFee (#431) is set pre-construction with a non-constant function or state variable:
- _liquidityAndPromoFee
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-0.8.4 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.

Low level call in Address.functionDelegateCall(address,bytes,string) (#132-136):
- (success,returndata) = target.delegatecall(data) (#134)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
