King Cardano is the king of tokens. This is the first auto-claim ADA token with the highest paying yields of up to 9%. Simply hold KADA tokens and get rewarded in ADA on every transaction.
There’s NO waiting or need to claim your rewards. It happens instantly and automatically.
The longer you hold KADA tokens, the more you earn in rewards and the closer you are to becoming the King. Why settle for 7-8% rewards or waiting around for your rewards when we can reward holders instantly with 9% from every BUY & SELL transaction!
Additionally, we the King Cardano protocol leads to a rise in price on EVERY transaction. 3% of each transaction gets bought back in the open market and burned forever, therefore increasing the value on everyone’s coins

KINGCARDANO.swapBack() (#721-757) ignores return value by address(marketing).call{gas: 30000,value: amountBNBMarketing}() (#746)

KINGCARDANO.swapBack().e (#748) 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
KINGCARDANO.setSwapBackSettings(bool,uint256) (#832-838) should emit an event for:
- swapThreshold = _amount (#837)
Emit an event for critical parameter changes.
Additional information: link
KINGCARDANO.setMarketingWallet(address)._marketing (#828) lacks a zero-check on :
- marketing = _marketing (#829)
Check that the address is not zero.

Variable 'KINGCARDANO.swapBack().e (#748)' in KINGCARDANO.swapBack() (#721-757) potentially used before declaration: SwapBackFailed(string(abi.encodePacked(SwapBack failed with error ,e))) (#749-751)
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.

DividendDistributor.process(uint256) (#381-407) has costly operations inside a loop:
- currentIndex ++ (#404)
Use a local variable to hold the loop computation result.

Context._msgData() (#65-68) is never used and should be removed
Remove unused functions.
Additional information: link
KINGCARDANO.swapThreshold (#572) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 5000
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.

Low level call in KINGCARDANO.swapBack() (#721-757):
- address(marketing).call{gas: 30000,value: amountBNBMarketing}() (#746)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable KINGCARDANO._totalSupply (#560) is not in mixedCase
Follow the Solidity naming convention.

Use: Ether suffix, Time suffix, or The scientific notation

KINGCARDANO.buyBackUpperLimit (#549) should be constant
Add the constant attributes to state variables that never change.

approve(address,uint256) should be declared external:
- KINGCARDANO.approve(address,uint256) (#896-904)
