CTB [CatBoy] Token
About CTB
Listings
Website
Catboy is a reflection-based token but we are unlike any other similar project you have come across.
Founded and built by a community that loves comics, manga, anime and pets, CatBoy is not just a parallel version of CatGirl but our ambition is much more. This token is a symbol of the spirit, cohesion and sharing of the meme, manga and cat loving communities around the world.
CatBoy is a more complete, more powerful version and will be the mainstay of CatGirl, just like their love.
Besides building a strong community, we care about the real values that the project brings. We are building the Catboy Merchandise, the Catboy NFT Marketplace and building a worldwide network to donate to feral cats and support struggling cat owners.
With a further vision in 2021, a play-to-earn game is also being planned with an online pet model, connecting the community and sharing fun experiences.

CatBoy.addLiquidity(uint256,uint256) (#1134-1144) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityAddress,block.timestamp) (#1136-1143)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Ownable._lockTime (#209) is never initialized. It is used in:
- Ownable.getUnlockTime() (#245-247)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

CatBoy._transfer(address,address,uint256) (#992-1082) uses a dangerous strict equality:
- from != owner() && to != uniswapV2Pair && block.number == tradingActiveBlock (#1014)
Don't use strict equality to determine if an account has enough Ether or tokens.

Fix or remove the writes.

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.

CatBoy._previousLiquidityFee (#645) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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-0.8.9 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.
