MW2 [Moonway] Token
About MW2
Listings
Website
MoonWay is a deflationary, yield-generating token that utilizes a democratized voting system to allow holders to vote on development decisions with the project. A community vote will be taking place this week to determine the direction the project will go: a game, a casino, or a charity. This project became entirely community driven after the developer renounced ownership and sold his tokens on launch day.
A 10% tax is applied to all transactions of which 5% is distributed to fellow MoonWay holders. The remaining 5% is added to a locked liquidity pool to generate an ever rising price floor. A total of 400 trillion tokens were burned at launch which equates to 40% of the total supply. Another 525 trillion tokens were committed to Pancakeswap for liquidity. The liquidity is locked forever, with Cake-LP sent to a dead address.

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.

solc-0.8.10 is not recommended for deployment
Pragma version=0.8.10 (#5) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
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._functionCallWithValue(address,bytes,uint256,string) (#151-173):

Low level call in Address.sendValue(address,uint256) (#101-111):
- (success) = recipient.call{value: amount}() (#106)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
