Matic Token Smart Contract Audit

Project Background

  • These Solidity codes are for implementing an ERC20 token along with functionalities like pausing/unpausing transfers. Let’s break down the provided code:
    • ERC20 Interface: The `IERC20` interface defines the standard functions and events for an ERC20 token.
    • SafeMath Library: This library contains functions for safe arithmetic operations to prevent overflow and underflow vulnerabilities.
    • ERC20 Contract: The main ERC20 contract implements the token functionality according to the ERC20 standard. It includes functions for transferring tokens, approving spending, and allowance management.
    • Roles Library and PauserRole Contract: These define a role-based access control system. The `PauserRole` contract allows certain accounts to pause and unpause token transfers.
    • Pausable Contract: This contract adds pausing functionality to the token. When paused, transfers are halted.
    • ERC20Pausable Contract: This contract combines ERC20 functionality with pausing capabilities.
    • ERC20Detailed Contract: This contract provides additional information about the token, such as its name, symbol, and decimals.
    • MaticToken Contract: This is the main token contract that inherits from `ERC20Pausable` and `ERC20Detailed`. It initializes the token with an initial supply and mints tokens to the contract deployer.
  • This code creates a token with ERC20 functionality along with the ability to pause/unpause token transfers.

Executive Audit Summary

  • According to the standard audit assessment, the Customer`s solidity smart contracts are “Secured”.  Also, these contracts contain owner control, which does not make them fully decentralized.
  • We used various tools like Slither, Solhint and Remix IDE. At the same time this finding is based on critical analysis of the manual audit.
  • We found 0 critical, 0 high, 0 medium,  0 low and 2 very low-level issues.
