 ## Introduction
 ### Purpose
-This document outlines a high-level architecture and threat model for the token bridge between Ethereum ("Root" chain) and the Immutable zkEVM ("Child" chain) chains. The bridge facilitates the transfer of ETH, IMX, and standard ERC20 tokens between these chains, using an underlying General Message Passing (GMP) bridge, Axelar, for message transmission. This bridge is a critical piece of infrastructure for the Immutable zkEVM chain, that will potentially custody significant amount of user assets.

This bridge is a critical piece of infrastructure for the Immutable zkEVM chain.
 
 The purpose of this document is to two-fold:
 1. Provide a high-level view of the Immutable zkEVM bridge's architecture, in terms of its core functionalities and use-cases, major components and their interactions, dependencies and architectural characteristics.
