Hierocoin - Smart Contract Audit Report

Summary

Hierocoin ($BAR) is a new BEP20 token on the Binance Smart Chain.

We reviewed the Hierocoin contract that is deployed at 0x34550001Fbf7d6e42e812763C91eF96F129742AB on the Binance Smartchain mainnet.

Notes on the Contract:
The total supply of the token is set to 93 million $BAR [93,000,000].
Any user can burn their own tokens to reduce the total supply.
At the time of writing this report, 91.19% of the total supply belongs to a Presale contract.
4.28% of the total supply belongs to a Unicrypt token vesting contract.
The next four holders own a cumulative 4.27% of the total supply.

Although there are team-restricted functions to mint tokens and pause trading that are present in the contract, the team has renounced their minting and pausing rights and can no longer access these functions.
No other ownership-restricted functions are present.
Some gas optimizations can be achieved through marking functions external instead of public. As this contract is already deployed, this is informational.
The contract complies with the BEP20 Token standard.
The contract utilizes Safemath libraries to prevent overflows/underflows.
