Matic Token Smart Contract Audit
Summary
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.
