# Overview

Welcome to the MAP Protocol documentation. This guide helps users, node operators, and application developers get started with MAP Protocol.

## What is MAP Protocol?

MAP Protocol is a peer-to-peer cross-chain infrastructure enabling secure interoperability between different blockchains. It supports:

* Cross-chain asset transfers
* Cross-chain messaging
* Omnichain application development

## Getting Started

### For Users

Learn about MAP Protocol and how to use cross-chain services.

* [Introduction](https://docs.mapprotocol.io/learn/introduction)
* [Architecture Overview](https://docs.mapprotocol.io/learn/architecture/overview)

### For Node Operators

Run nodes and participate in the network.

* [Run Node](https://docs.mapprotocol.io/run-node/overview)
* [Become Validator](https://docs.mapprotocol.io/validator/become-validator)
* [Run Compass-TSS (v2)](https://docs.mapprotocol.io/compass-tss-crossx/overview)
