ViCA Token - Audit Report

Summary

ViCA Token Audit Report ViCA Token ($ViCA) is a new ERC20 token on the Ethereum Blockchain.

We reviewed the ViCA contract at 0x19d4Beb2BC410B80084fCbD0ac024326F4D3a370 on the Ethereum mainnet.

Notes on the Contract:
The total supply of the token is set to 2 billion $ViCA [2,000,000,000].
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, 60% of the total supply has been sent to the 0x..dead address.
1.28% of the total supply is in Uniswap V3 liquidity.
The next five holders own a cumulative 0.236% of the total supply.

The contract complies with the ERC20 token standard.
Users have the ability to airdrop any amount of tokens to any destination addresses at any time.
Although the Safemath library is utilized, the contract is deployed with Solidity v0.8.0 which has built-in overflow checks. Safemath could be safely removed to reduce contract size and increase gas savings.
