Introduction

Omnichain Applications

Omnichain Applications (OApps) are a powerful evolution of traditional smart contracts. They allow signing transactions at any chain, while traditional smart contract applications only target users of a single chain.

An example of an OApp is SpaceWard – our application functioning as the front-end interface for Warden.

This sections explains how to build the backend and frontend of an OApp. Here you'll also find guides for running a node and a Keychain in the test mode.

Get started

The main part of any Omnichain Application is an Omnichain Contract: a smart contract that allows signing transactions and messages at any destination chain. For this reason, OApp development starts with building a custom Omnichain Contract with CosmWasm.
