Passive.Income - Audit Report

Summary

Passive.Income Audit Report Passive.Income is an innovative Ethereum token that re-imagines the concept of DeFI yield generation and changes this to DeFi passive income generation.

We audited Passive.Income's token contract, deployed at 0xd4cb461eace80708078450e465881599d2235f1a.

Overview of the Contract:
  • Users who hold tokens will automatically receive the fees from a transaction tax on each transfer.
  • The total supply of the token is set to 50,000 and no mint functions are present. After deployment, the total supply of tokens are all sent to the deployer's address.

  • Owners have the ability to exclude and include users from transfer fees.
  • As of the date of this report, Uniswap has been excluded from transaction fees.

  • The contract utilizes SafeMath libraries to prevent overflows along with following the ERC20 standard.
