Axie Infinity Shard Smart Contract Audit
Summary
The AXSToken smart contract is an ERC20 token. Here’s a breakdown of what each part of the code does: SafeMath.sol: This library provides functions for safe mathematical operations to prevent overflows and underflows. IERC20.sol: This is the interface for the ERC20 standard. It defines the functions and events that an ERC20 token contract must implement. ERC20.sol: This contract implements the ERC20 interface. It includes functions for transferring tokens, approving spending, and managing allowances. IERC20Detailed.sol: This interface extends the ERC20 interface with additional functions for getting the name, symbol, and decimals of the token. ERC20Detailed.sol: This contract implements the detailed ERC20 interface. It adds the name, symbol, and decimal properties to the ERC20 contract. ERC20GatewayWhitelist.sol: This contract extends the ERC20 contract and adds functionality to whitelist a mainchain gateway. It allows unlimited allowance for the gateway address and sets a limit for other addresses. AXSToken.sol: This is the main contract for the AXS token. It inherits from ERC20Detailed and ERC20GatewayWhitelist contracts. In the constructor, it sets the total supply, assigns all tokens to the contract deployer, and sets the mainchain gateway. Overall, this code defines an ERC20 token contract for Axie Infinity Shard (AXS) with additional functionality for whitelisting a mainchain gateway.
