Floki Wolf - Audit Report

Summary

Floki Wolf is a new BEP20 token with automatic liquidity adds, a buyback system for burning supply, and pays users dividends in BSC-USD.

The Floki Wolf contract is deployed at 0xD795B91283C0Ac70794aC9F8253759D396ffA7dE on the Binance Smartchain mainnet.

Notes on the Contract:

  • The total supply of the token is set to 1 quadrillion [1,000,000,000,000,000].
  • No mint or burn functions are present beyond deployment; though the circulating supply can be reduced by sending tokens to the 0x..dead address if desired.
  • At the time of writing this report, 100% of the total supply belongs to the owner as the contract was recently deployed.

  • There is a tax fee charged on each transaction that gets stored in the contract balance; fees can be increased during a sell to PancakeSwap up to a value proportional to the time left in the buyback multiplier period (if any).
  • Once a threshold value of tokens in the contract balance is met, a portion of the contract balance is swapped for BNB and distributed as dividends, and another portion is sent to the marketing wallet which is controlled by the project team.
  • Another portion is allocated to funding PancakeSwap liquidity, unless the liquidity cap set by the team has already been met.
  • Liquidity-adds are funded by selling half of the tokens allocated to funding liquidity, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
  • The newly created LP tokens are sent to an address controlled by the team. We recommend that the team locks these newly acquired LP tokens.
  • If the auto buyback functionality is enabled, and the amount of BNB in the contract reaches the autobuyback threshold value determined by the owner, the BNB will be swapped for $Flokiwolf tokens and sent to the burn address.

  • Any user that holds any amount of $Flokiwolf tokens are eligible to claim dividends once the amount of dividends they are due reaches a minimum threshold value determined by team.
  • Once dividends are distributed, they will need to be claimed; claiming happens automatically on each transfer.
  • Dividend rewards can also be claimed manually by kicking off the claim cycle, which will process all eligible token holders.
  • Alternatively, a user can manually claim dividends as an individual.
  • There is a wait-time between claiming dividend rewards.
  • Claimed dividends are sent to the user's wallet address.

  • Ownership Controls:
  • The owner can assign multiple addresses to an 'authorized' role. The assigned addresses have access to specific functions in the contract.
  • Any authorized address can set the total fees charged on transactions to any value up to 25% at any time.
  • Any authorized address can set the percentage of the fees allocated to any fund (liquidity, marketing, buyback, dividends) at any time.
  • Any authorized address can exclude any address from dividends at any time.
  • Any authorized address can update the minimum threshold value of rewards needed that determines when a user can claim their dividends.
  • Any authorized address can set a maximum transaction limit which is enforced during sell transactions to PancakeSwap. Any authorized address can also exclude accounts from this maximum transaction limit.
  • Any authorized address can automatically trigger a buyback at any time.
  • Any authorized address can set or disable the buyback fee multiplier at any time.
  • Any authorized address can disable the autobuyback system and set any the threshold BNB value to trigger a buyback.
  • Any authorized address can disable the automatic liquidity adds at any time and set any threshold value related to it.
  • Any authorized address can update the Dividend Distributor and PancakeSwap Router contract addresses at any time.
  • Any authorized address can update the maximum amount of gas used for processing to a value up to 750,000 at any time.
  • Any authorized address can update the amount of time a user must wait between claiming dividends to any value at any time.
Audit Findings Summary
  • No external threats were identified.
  • Please ensure trust in the team prior to investing as they have substantial control in the ecosystem and currently own 100% of the total supply.
