Arbitrum (ARB) Token Smart Contract Audit

Project Background

  • The Arbitrum token is a Permit token registered with an Arb One and Nova counterpart.
  • The `L1ArbitrumToken` contract combines standard ERC20 features with permit functionality and integrates with the Arbitrum bridge infrastructure, facilitating secure token bridging between Ethereum (L1) and Arbitrum (L2) networks. It supports:
    • Initialization with specific gateway and router addresses.
    • Minting and burning of tokens controlled by the Arbitrum One gateway.
    • Registration on both Arbitrum One and Nova networks.
    • Standard ERC20 balance and transfer functions with additional interface compatibility.
  • This design ensures robust and secure handling of ERC20 tokens that interact with the Arbitrum network, providing flexibility and security for cross-layer operations.
