Axelar Core is the main application of the Axelar Network, built on the Cosmos SDK. It powers a decentralized interoperability protocol that connects EVM-compatible chains (Ethereum, Polygon, Avalanche, and more), IBC-enabled Cosmos chains, and CosmWasm smart contract platforms into a unified messaging fabric.

Introduction

Understand what Axelar Core is, how it works, and who it’s for

Quickstart

Build and run your first Axelar node in minutes

Architecture

Deep dive into the module architecture and cross-chain flow

CLI Reference

Complete reference for all axelard commands and flags

Run a Node

Whether you’re a validator joining the active set or a developer running a local node, get up and running quickly.
1

Build the binary

Compile axelard from source or download a verified release binary. Static builds are recommended for portability.
2

Initialize and configure

Run axelard init to generate your node’s keys and configuration files, then tune app.toml and config.toml for your environment.
3

Start the node

Launch the full node with axelard start. Validators also run the vald sidecar daemon to monitor external chains and participate in signing.
4

Register as a validator

Create a validator, register a proxy with axelard tx snapshot register-proxy, and opt in to keygens with axelard tx multisig keygen opt-in.

Core Modules

Axelar Core’s interoperability is built on a set of custom Cosmos SDK modules working together.

Nexus

The routing hub — manages cross-chain messages, asset registration, and chain state

EVM

EVM chain integration — gateway contracts, command batching, and event confirmation

Axelarnet

IBC connectivity — links Cosmos chains via IBC paths and routes transfers

Multisig

Threshold signing — manages key generation, rotation, and signing sessions

Governance & Operations

Governance

On-chain parameter changes, chain activation, and governance key management

Chain Management

Register EVM and Cosmos chains, deploy tokens, and manage maintainers

Upgrades

Software upgrade process, migration guides, and release verification

Security

Binary verification, bug bounty, and responsible disclosure
