CatGirl Token - Audit Report

Summary

 CatGirl Audit Report The CatGirl Coin is a new token with frictionless fee redistribution, liquidity adds, and a lottery mechanism.

We reviewed CatGirl Token's contract at 0x79ebc9a2ce02277a4b5b3a768b1c0a4ed75bd936 on the BSC mainnet.

Features of the Contract:
  • The total supply of the token is 100 quadrillion.
  • No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to the burn address.
  • 60% of the token's supply is held in the burn address.
  • 3.1% of the token's supply is in the liquidity pool.
  • 91% of liquidity is locked for 1 year. 8% of liquidity is unlocked and held by the team.
  • The next largest holder has 1%.
  • Multiple fees are changed on each transfer of the token. There are fees allocated towards liquidity, frictionless redistribution, and the lottery pool.
  • One the lottery pool reaches a threshold value set by the team, a user holding a minimum number of tokens (also set by the team) will be pseudo-randomly chosen as the winner.
  • The lottery winner will receive all of the tokens held in the pool.
  • The owner can exclude any address from the fee mechanism and update the maximum amount which can be sent in a single transaction to any value.
  • The owner can also set fees to any amount at any time. We advise renouncing ownership.
  • Utilization of SafeMath to prevent overflows.

Audit Findings Summary:
  • No security issues from outside attackers were identified.
  • Ensure trust in the team as they have notable control in the ecosystem.
  • Date: June 14th, 2021.
