ChowChow.finance - Audit Report

Summary

CHOW Audit Report CHOW is an innovative Ethereum token that re-imagines enables uses to reap passive income by holding the token.

We audited CHOW's token contract, deployed at 0x925f2c11b99c1a4c46606898ee91ed3d450cfeda.

Update March 30th, 2021: CHOW has also been deployed to the Binance Smart Chain at 0x925f2c11b99c1a4c46606898ee91ed3d450cfeda.

Overview of the Contract:
  • The total supply of the token is set to 100 million and no mint functions are present.
  • After deployment, the total supply of tokens are all sent to the deployer's address.
  • The Uniswap liquidity pool holds 30% of the token's supply (~30M tokens). 100% of this liquidity has been locked by the team until May 2nd, 2021.
  • After deployment, the team sent ~50% of the supply to ~50 different addresses for the presale.

  • The token includes a fee-on-transfer mechanism.
  • Users who hold tokens will automatically receive 100% of the fees from a transaction tax on each transfer; distributed among token holders based on the amount they possess.

  • Owners have the ability to exclude and include users from transfer fees.
  • As of the date of this report, Uniswap has been NOT been excluded from transaction fees. We reccomend doing so to avoid liquidity imbalances.
  • The contract utilizes SafeMath libraries to prevent overflows along with following the ERC20 standard.
