Simba Empire Token - Smart Contract Audit Report

Summary

Simba Empire Token Audit Report Simba Empire ($SIM) is a new ERC20 token on Polygon.

For this audit we reviewed the project's token contract, deployed at 0x31D457E7bcFf5Bc9A5Ef86E6a5eA1DB5b5C3BFB0 on the Polygon mainnet.

Notes of the contract:
  • The total supply of the token is 300 million $SIM [300,000,000].
  • No mint functions are accessible after deployment.
  • Any user can burn their own tokens to reduce the total supply.
  • At the time of writing this report, 82.33% of the total supply is in possession of the owner.
  • The next five holders account for ~2% of the total supply.
  • 1.97% of the total supply is in Uniswap liquidity.
  • Of that liquidity, the owner is in possession of 99.92% of the LP tokens.

  • The owner has the ability to disable trading at any time. This feature can be toggled on/off by the owner.
  • No other ownership-restricted functions are present.
  • Some gas optimizations can be achieved through declaring functions external instead of public. As this contract is already deployed, this is merely informational.
  • As the project is deployed with Solidity v0.8.0, it is protected from overflows.
  • This contract complies with the ERC20 standard.
Audit Findings Summary
  • No issues from external attackers were identified.
  • Please ensure trust in the team prior to investing as they have control over a large portion of the total token supply.
  • Date: August 16th, 2021.
