Smart Contract Audit Report

Audit Summary

BudBlockz Audit Report BudBlockz is a new ERC-20 token on Ethereum.

For this audit, we reviewed the project team's BluntToken contract at 0xf3d19c0f7c273914bf2e9b257b2dc8f247bf799d on the Ethereum Mainnet.

Audit Findings

Informational findings were identified and the team may want to review them.
Date: September 14th, 2022.
Updated: September 20th, 2022 to reflect the project's newly deployed Mainnet address.

Finding #1 - BluntToken - High (Resolved)

Description: Any user can repeatedly call any of the contract's eight mint functions and mint the fixed number of tokens assigned to the function to their own address.
function Presale() public returns (bool) {
    _mint(msg.sender, PRESALE_SUPPLY); 
function Marketing() public returns(bool) {
    _mint(msg.sender, Marketing_SUPPLY);
function Liquidity() public returns(bool) {
    _mint(msg.sender, Liquidity_SUPPLY);    
function Founders() public returns(bool) {
    _mint(msg.sender, Founders_SUPPLY);
function PrivateFunc() public returns(bool) {
    _mint(msg.sender, Private_SUPPLY);
function ProjectPartners() public returns(bool) {
    _mint(msg.sender, ProjectPartners_SUPPLY);
function Developers() public returns(bool) {
    _mint(msg.sender, DEV_SUPPLY);
function Howhigh() public returns(bool) {
    _mint(msg.sender, HowHigh_SUPPLY);
Risk/Impact: Any user can mint tokens to their own address until the total supply reaches Solidity's maximum integer value.
Recommendation: All eight mint functions should be modified to ensure that only a wallet controlled by the team can call each function one time.
Resolution: The team has removed the eight mint functions from the contract.

Finding #2 - BluntToken - Informational

Description: The following state variables are not used in the contract.
PRESALE_SUPPLY, Marketing_SUPPLY, Liquidity_SUPPLY, Founders_SUPPLY, Private_SUPPLY, ProjectPartners_SUPPLY, DEV_SUPPLY, HowHigh_SUPPLY
Recommendation: The above state variables should either be removed to reduce contract size and deployment costs or utilized in a way that fits the project team's intended functionality.

Contract Overview

  • The total supply of the token is set to 420 million $BLUNT [420,000,000].
  • No burn functions are accessible, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
  • At the time of writing this report, 100% of the total supply belongs to the deployer.

  • There are no fees associated with transferring tokens.
  • No owner-restricted functionality is present in the contract.
  • The contract utilizes the SafeMath library to protect against any possible overflows/underflows.
  • The contract complies with the ERC-20 token standard.

What is a Solidity Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A Solidity Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.

How Do I Interpret the Findings?

Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:

  • High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
  • Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
  • Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
  • Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
