VoltBit - Smart Contract Audit Report
Summary
VoltBit is a new token with frictionless fee redistribution and charity contributions on each transfer.
The contract has now been deployed to 0xe78a58acb18811e840dd828d4f0116389e953592 on the BSC mainnet.
Overview of the Contract:Audit Findings Summary
- The total supply of the token is set to 500,000,000.
- No mint or publicly accessible burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- As of the date of the report the team holds 92.3% of the supply for the presale.
- 6.7% of the supply was distributed to private sale participants.
- Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
- Another portion of the fee charged on transactions is sent to a charity wallet which is controlled by the team.
- The owner can also update the charity address at any time.
- The owner can also set the maximum transaction size, down to a minimum of 10% of the total supply.
- The owner of the contract can enable and disable the swap and liquify logic.
- Tax fees cannot be changed.
- Public functions not used internally could be declared external instead of public to save some gas.
- The contract utilizes SafeMath to prevent overflow issues.
- No security issues were identified in our analysis.
- As with any presale, ensure trust in the team prior to sending them funds.
- Further, ensure trust in the team as they will collect tokens via the charity wallet.
