SnowCrash Audit Report SnowCrash Token ($Nora) is a new community-driven BEP20 token.

The SnowCrash Token contract is deployed at 0x1f39dd2bf5a27e2d4ed691dcf933077371777cb0 on the Binance Smartchain mainnet.

Notes on the Contract:
  • The total supply of the token is set to 102.4 million [102,400,000] $Nora.
  • No minting or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
  • At the time of writing this report, 20% of the total $Nora token supply is stored in a token locking contract. Half of these tokens will vest to the team on June 4th, 2022. The remaining half will vest to the team on June 4th, 2023.
  • The top five holders own a cumulative 14.89% of the total supply.
  • 3.68% of the total supply is in Pancakeswap liquidity.
  • Of that liquidity, 87.11% of the LP tokens are stored in a token locking contract that will vest to the team on June 4th, 2022.
  • The next five holders own 7.89% of the LP tokens.

  • No ownership-restriction functions are present.
  • The contract complies with the BEP20 standard.
  • As the project is implemented with Solidity v0.8.0, it is protected from overflows.
