white paper

Yarloo is a P2E company that utilizes NFTs as the core asset behind gameplay mechanics and the P2E model, in addition to their very own RST (Revenue Sharing Token) method, which distributes a percentage of the company's monthly revenue across ""pillars"" that support market value and encourage more community activities.

The first flagship project to launch under Yarloo's development is a trading card game called ""Pirateers"" - which concentrates on bringing seasonal content in a similar formula to how renowned AAA studios utilize their service-based games, and bring them to crypto gaming to maintain the game's longevity.

Yarloo was originally founded in January of 2021 originally as a trading card game lottery concept then later pivoted into a full-on gaming company. The team is international, with most of the company's members in Brazil, and the Netherlands.

The project was launched publicly in August, with Binance Smart Chain and Polygon for the first network launches given how user-friendly they are in terms of fees, as the company seeks to avoid large transaction fees so as not to lose traffic for the games or the ecosystem's projects in general.

Yarloo has a number of upcoming projects in the roadmap as well, like Battleships, a PVP/PVE fleet-building strategy game that will allow players to customize their own NFT ships, conquer certain areas of the seas, and try to take the most control possible over the world's map - on top of that is an interoperable cross-chain marketplace named NFTShore, due for release in 2021.

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.

Variable Yarloo._getRValues(uint256,uint256,uint256,uint256,uint256).rTransferAmount (#860) is too similar to Yarloo._transferFromExcluded(address,address,uint256).tTransferAmount (#811)
Prevent variables from having similar names.

Yarloo._previousBurnFee (#523) is never used in Yarloo (#494-976)
Remove unused state variables.

Additional information: link

Yarloo._taxFee (#519) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setSwapAndLiquifyEnabled(bool) should be declared external:
- Yarloo.setSwapAndLiquifyEnabled(bool) (#954-957)
Use the external attribute for functions never called from the contract.

Rename the local variables that shadow another component.

Check that the address is not zero.

Yarloo._previousMarketingFee (#527) is set pre-construction with a non-constant function or state variable:
- _marketingFee
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.
