Cowboy Zombies Token - Audit Report


Cowboy Zombies Token Audit Report Cowboy Zombies Token ($CZ) is a new community-driven BEP20 token on the Binance Smart Chain.

The Cowboy Zombies Token contract is deployed at 0x64B5D35543D03aDf447286f69383e3E76eF6f8BE on the Binance Smart Chain mainnet.

Notes on the Contract:
  • The total supply of the token is initially set to 100 million $CZ [100,000,000].
  • No mint or burn functions are present beyond deployment; though the circulating supply can be reduced by sending tokens to the 0x..dead address if desired.
  • At the time of writing this report, 100% of the total $CZ token supply is in possession of the owner as the project was recently deployed.

  • There is a tax fee that is charged on transfers when sending tokens to Pancakeswap (selling).
  • The tokens collected from this fee are sent directly to the team's 'taxAddress'. This address is currently set to the owner's address, however the owner can update this address to a new wallet at any time.
  • The owner has the ability to modify the tax fee to any percentage at any time.
  • The owner has the ability to exclude and include accounts from the tax fee.
  • Ownership has not been renounced.
  • Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant. As this contract is already deployed, this is merely informational.
  • As the project is implemented with Solidity v0.8.x, it is protected from overflows.
Audit Findings Summary
  • No external threats were identified.
  • We recommend that the team renounces ownership.
  • Please ensure trust in the team prior to investing as they have some control in the ecosystem.
