ZenFi AI Audit Report

ZenFi AI ($ZENFI) is a new BEP-20 token on the Binance Smart Chain.

We reviewed the ZENFI contract at 0xA84d7A90bDbBe6dE3FFFe9B7F549366320EF90D3 on the Binance Smart Chain mainnet.

Notes on the Contract:
  • The total supply of the token is set to 42 million $ZENFI [42,000,000].
  • No mint 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, 99.72% of the total supply belongs to the deployer.
  • 0.0457% of the total supply is in Pancakeswap BSC-USD-ZENFI liquidity.
  • Of that liquidity, 100% of the LP tokens belong to a token vesting contract behind a proxy.
  • The next five holders own a cumulative 0.0322% of the total supply.

  • The contract complies with the BEP-20 token standard.
  • There are no fees associated with transferring tokens.
  • The owner can withdraw any BEP-20 tokens erroneously sent to the contract address.
  • The contract utilizes the SafeMath library to prevent overflows/underflows.
  • Some gas optimizations can be achieved through declaring functions external instead of public. As this contract is already deployed, this is merely informational.

Audit Findings Summary
  • No external threats were identified.
  • Please ensure trust in the team prior to investing as the deployer currently owns 99.72% of the total supply.
