Rebel Satoshi Arcade

Smart Contract Audit Report

Executive Summary

This report presents the outcomes of our collaborative engagement with the Rebel Satoshi team, focusing on the comprehensive evaluation of the RebelSatoshiArcade contract.

Our team conducted an initial security assessment from March 19th to March 21st, 2024.

Rebel Satoshi is a new ERC-20 token deployed on Ethereum. Its purpose is to underpin all transactions, purchases, fees, and rewards within the wider Rebel Satoshi universe.

Audit Findings

Informational findings were identified and the team may want to review them. In addition, some centralized aspects are present.

Finding #1	RebelSatoshiArcade	InformationalOpen
Finding #1 - RebelSatoshiArcade InformationalOpen
Description: The `uniswapV2Pair` and `uniswapV2Router` state variables can only be set one time in the constructor but are not declared immutable. Recommendation: The above state variables could be declared immutable for additional gas savings on each reference.
Finding #2	RebelSatoshiArcade	InformationalOpen
Finding #2 - RebelSatoshiArcade InformationalOpen
Description: Although the SafeMath library is utilized, the contract is deployed with Solidity v0.8.17 which has built-in overflow checks. Recommendation: SafeMath could be safely removed to reduce contract size, deployment costs, and gas costs on all transactions that utilize it.

System Overview

TOKENOMICS

The total supply of the token is set to 3 billion $RECQ (3,000,000,000) with the entire supply being minted directly to the specified owner's address upon deployment. After deployment, minting is no longer accessible. No burn functions are accessible though the total supply of the token can be reduced by transferring tokens to the 0x..dead address.

AUTOMATIC LIQUIDITY ADDS

When the contract executes a transfer that is classified as a sell, and the swapping functionality has been enabled by the owner, several conditions are evaluated to initiate an automatic liquidity add. This process executes only if the contract's token balance reaches the predetermined threshold and no swap is currently in progress. Half of the threshold's token value is swapped for ETH, which is then transferred back to the contract. This received ETH is then paired with the other half of the tokens and subsequently added as liquidity to the RECQ-ETH pair.

The LP tokens received through the automatic liquidity add process are sent to the contract. As the owner can withdraw any tokens from the contract at any time, we recommend the team lock these newly acquired LP tokens. There are no fees associated with transferring tokens. Tokens must be manually supplied to the contract in order for swaps to be able to occur.

OWNERSHIP CONTROLS

The owner can set the threshold number of tokens in the contract needed to perform an automatic liquidity add to any value up to 3 billion (100% of the total supply). The owner can enable/disable the automatic liquidity add functionality at any time. The owner can add/remove any address as an Automated Market Maker Pair address at any time. The owner can withdraw any tokens or ETH from the contract at any time.

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.
