Smart Contract Audit Report

Audit Summary

Rocket Global Coin Audit Report Rocket Global Coin is a new BEP-20 token on the Binance Smart Chain that is an automatic liquidity providing protocol.

For this audit, we reviewed the project team's Token contract at 0x7658604d32a0e60D08dd77A60413897E5CeFD51f on the Binance Smart Chain Mainnet.

Audit Findings

Please ensure trust in the team prior to investing as they have some control in the ecosystem and currently own 100% of the total supply.
Date: April 28th, 2022.

Finding #1 - Token - Informational

Description: Although the SafeMath library is utilized, the contract is deployed with Solidity v0.8.9 which has built-in overflow checks.
Recommendation: SafeMath could be safely removed to reduce contract size and deployment costs.

Contract Overview

  • The total supply of the token is set to 750 million $RCKC [750,000,000].
  • No mint or burn functions exist, 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 owner.

  • Trading must be enabled by the owner before transfers can take place on the platform. Only accounts that are excluded from fees can transfer tokens when trading is disabled.
  • There is a Liquidity fee, Marketing fee, Dev fee, and Buyback fee on all transfers where neither the sender nor the recipient is excluded from fees. A separate fee structure can be set by the team to apply different fee percentages depending on whether the transfer is a buy or a sell.
  • The tokens collected through fees are stored in the contract address. The tokens are swapped for BNB for the purpose of funding Pancakeswap liquidity when the following conditions are met:
    • The automatic liquidity add functionality is enabled by the team.
    • The threshold number of tokens (determined by the owner) in the contract address has been reached.
    • The contract is not currently performing an automatic liquidity add.
    • The caller is not initiating a buy transaction via Pancakeswap.
    • Both the sender and recipient are not excluded from fees.
  • Liquidity-adds are automatically performed by selling the tokens collected as fees, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
  • The LP tokens received through this process are sent to the 0x..dead address.
  • The tokens collected through the Dev fee and Buyback fee are swapped for BNB and sent to the team's Dev wallet and Buyback wallet respectively.
  • The remaining BNB in the contract is sent to the team's Marketing wallet.
  • The contract utilizes the SafeMath library to protect against overflows/underflows.
  • The contract complies with the BEP-20 token standard.
Ownership Controls:
  • The owner can modify total buy fees up to 20% and total sell fees up to 30%.
  • The owner can exclude and include accounts from transfer fees.
  • The owner can enable/disable automatic liquidity adds at any time.
  • The owner can update the threshold number of tokens needed to trigger an automatic liquidity add to any value greater than 7,500 at any time.
  • The owner can update the team's Marketing wallet, Dev wallet, and Buyback wallet at any time.
  • The owner can update the Pancakeswap Pair address at any time.
  • The owner can airdrop any number of tokens to up to 200 accounts per transaction while trading is disabled.

What is a SourceHat Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A SourceHat 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.
