PAPP Token - Smart Contract Audit Report

Summary

PAPP Token Audit Report PAPP is a new token project on the Binance Smart Chain.

For this audit we reviewed the project's token contract, deployed at 0xcd77880edea8e7d1f2be011be560b45b96ba68ad on the Binance Smart Chain.

Notes of the Contract:

  • The initial total supply is 25 thousand tokens.
  • There is no way for tokens to be minted after deployment.
  • No ownership-restricted functions are present.
  • One wallet holds 6% of the token's supply.
  • 4.5% of the token's supply is held as liquidity.
  • 99% of liquidity is locked until October 12th.
  • 12 wallets have between 1% and 4.4% of the token's supply.
  • Some functions could be declared external instead of public to save a minimal amount of gas.
  • The token contract complies with the ERC20 standard.
  • The contract does not use SafeMath and may be suseptible to overflow attacks.
Audit Findings Summary:
  • The token may allow for overflow attacks and other unexpected behavior due to the lack of SafeMath.
  • Be aware of the wallets which hold a large number of tokens in relation to the liquidity pool.
  • Date: May 9th, 2021.
