FIRE - Audit Report

Summary

FIRE Audit Report FIRE is a new token with frictionless fee redistribution.

We audited FIRE's token contract at 0xBaCbF768795C50FC5E877830A127276741651D0a on the Binance Smart Chain mainnet.

Overview of the Contract:
  • The total supply of the token is set to one billion.
  • No mint or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
  • Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
  • A portion of the fee charged on transactions is stored in the contract and, once a threshold value is met, used to fund PancakeSwap liqudity.
  • Liquidity-adds are funded by selling half of the tokens collected as fees, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.

  • There is a transfer limit on the number of tokens in each transaction set at 5 million. There is also an anti-whale mechanism which disallows any address from receiving more than the maximum transaction amount in their wallet.
  • By default trading is disabled and the anti-whale mechansim on until the owner alters these variables.
  • The contract utilizes Solidity 0.8.4 which has built-in overflow checks and the token follows the BEP20 standard.

Audit Findings Summary
  • No security issues were identified in our analysis.
