Volt Inu - Smart Contract Audit Report

Summary

Volt Inu Audit Report Volt Inu ($VOLT) is a new ERC-20 token on the Ethereum Blockchain that is an automatic liquidity providing protocol that pays out static rewards to holders.

We reviewed the VOLT contract at 0x3F7Aff0EF20AA2E646290DfA4E67611B2220C597 on the Ethereum mainnet.

Notes on the Contract:
The total supply of the token is set to 69 sextillion $VOLT [69,000,000,000,000,000,000,000].
No minting 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, 17.75% of the total supply is in Uniswap liquidity.
Of that liquidity, 56.91% of the LP tokens have been sent to the 0x00 address.
37.72% of the LP tokens belong to a Unicrypt token locking contract and will vest to the team on December 19th, 2022.
The next five holders own a cumulative 9.65% of the total supply.

There is a 1% tax fee and a 12% liquidity fee on all transfers where neither the sender nor the recipient is excluded from fees.
The tokens collected from the tax fee are removed from the circulating supply; This serves as a frictionless fee redistribution which automatically benefits all token holders at the time of each transaction.
The tokens collected from the liquidity fee during transfers are stored in the contract address balance. Once the threshold value of 690 quintillion tokens is met, a swap will occur for the purpose of funding Uniswap liquidity.
Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshold number of tokens is met), then pairing the received ETH with the token, and adding it as liquidity to the ETH pair.
The recipient of the newly created LP tokens is the 0x00 address.
The remaining portion of ETH is split between the team's Marketing wallet and Dev wallet respectively.
Although a maximum transaction amount is enforced on all transfers, it is set to 100% of the total supply and cannot be modified.
exists, however the impact is very low.
The liquidity pool address is not excluded from rewards which will cause extra tokens to be unaccounted for in the liquidity pool. These extra tokens are prone to a theft-of-liquidity attack, however the impact this would have on the project overall is very minor.
Although the Safemath library is utilized, the contract is deployed with Solidity v0.8.9 which has built-in overflow checks. Safemath could be safely removed to reduce contract size and increase gas savings.
Some gas optimizations can be achieved through declaring functions external instead of public and some state variables constant. As this contract is already deployed, this is merely informational.
Ownership has been renounced.
Audit Findings Summary
The liquidity pool address is not excluded from rewards which will cause extra tokens to be unaccounted for in the liquidity pool. These extra tokens are prone to a theft-of-liquidity attack, however the impact this would have on the project overall is very minor.
