Intimate

Smart Contract Audit Report

Audit Summary

Intimate is a new ERC-20 token that is an automatic liquidity providing protocol that pays out static rewards to holders.

For this audit, we reviewed the project team's IntimateToken contract at 553c816d00e2d24c4f47cb52621250460118fe2c on the team's private Github repository.

We also reviewed the project team's BridgeETH and BridgeBSC contracts here.

Audit Findings

Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
Date: April 12th, 2022.
Updated: April 28th, 2022 to reflect the contract's latest commit on Github.

Contract Overview

  • The maximum supply of the token is set to 500 trillion $INTI [500,000,000,000,000].
  • After deployment, The Bridge contract can mint tokens up to the maximum supply to any address at any time.

  • The owner must manually enable trading before all transfers can take place on the platform. Only the owner can transfer tokens when trading is disabled. Once trading is enabled it can never be disabled.
  • The contract enforces a maximum transaction amount (determined by the owner) which imposes a limit to the number of tokens that can be transferred in a single transaction.
  • There is a Tax fee and a Liquidity fee on all transfers where neither the sender nor the recipient is excluded from fees.
  • The tokens collected through the Tax fee are removed from the circulating supply; This serves as a frictionless fee redistribution that automatically benefits all token holders at the time of each transaction.
  • The Liquidity fee charged during transfers is stored in the contract address. The tokens are swapped for ETH for the purpose of funding Uniswap liquidity when the following conditions are met:
    • The automatic liquidity add functionality is enabled by the team.
    • The threshold number of 500,000 tokens 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 Uniswap.
  • Liquidity-adds are automatically performed by selling the tokens collected as fees, pairing the received ETH with the token, and adding it as liquidity to the ETH pair.
  • The LP tokens received through this process are sent to the owner. We recommend that the team lock these newly acquired LP tokens.
  • The contract utilizes the SafeMath library to protect against overflows/underflows.
  • The contract complies with the ERC-20 token standard.
Ownership Controls:
  • The owner can modify the Tax fee and Liquidity fee to any percentages at any time.
  • The owner can exclude and include accounts from transfer fees and reward distribution.
  • The owner can set the maximum transaction amount to any value at any time.
  • The owner can enable/disable automatic liquidity adds at any time.
  • The owner can set the Bridge contract to any address at any time.
  • The owner can update the Uniswap Router address at any time.

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.
