NFTTone - Smart Contract Audit Report
Summary
NFTTone ($TONE) is a new community-driven Defi token on the Binance Smart Chain that is an automatic liquidity providing protocol that pays out static rewards to holders.
Overview of the Contract:Audit Findings Summary
- The total supply of the token is set to one quadrillion [1,000,000,000,000,000].
- 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 19.6% of the total supply has been burned.
- There is a wallet that has 8.15% of the total token supply.
- Pancakeswap holds ~5.9% of the token's supply as liquidity.
- As of the date of this report, ~98.5% of the liquidity is locked in an unverified contract.
- The next largest wallet has 3.6%.
- Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
- A portion of each transaction is sent to a charity wallet.
- A portion of the fee charged on transactions is stored in the contract and, once a threshold value is met, these tokens will be sold for BNB and stored in the contract.
- The owner of the contract can transfer BNB out of the contract at any time to the charity wallet and marketing wallet. The charity wallet address can be set at any time.
- The owner can enable and disable fees at any time. However, the fee structure cannot be changed, only toggled on/off.
- The owner of the contract can exclude and include users from transfer fees, and update the maximum transaction amount.
- There is a transfer limit, but it is set to the total supply. While the team can update this, the minimum value is the total supply.
- Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
- Ownership has not been renounced.
- The contract utilizes SafeMath libraries to prevent overflows along with following the ERC standard.
- No security issues were identified in our analysis.
- Further, ensure trust in the team as they have substantial control in the ecosystem. We strongly recommend renouncing ownership.
