Introduction

Intelligent Applications​

Intelligent Applications are smart contracts integrating AI or any offchain logic. Unlike traditional contracts bound by static logic, Intelligent Apps unlock more dynamic user experiences: they are able to reason, adapt, and interact across onchain and offchain environments.

With Warden, you can build crypto super apps, smart AI Agents, and intelligent custody solutions. For example, see SpaceWard and the Warden App.

Smart contracts​

The main part of any Intelligent Application is a smart contract that allows signing transactions and messages at any destination chain. For this reason, Intelligent App development starts with building a custom smart contract. In contracts, you can interact with our modules and AVR Plugins to access all Warden's core features from any chain.

As shown below, Warden Protocol supports two smart contract platforms, allowing you to execute two types of smart contracts.

EVM contracts​

The x/evm Warden module allows executing Ethereum Virtual Machine (EVM) contracts charged by Evmos. They're written in Solidity.

Existing Solidity contracts are easy to deploy on Warden, so you can seamlessly port applications from any EVM-compatible chain to Warden and reach new users. You can call Warden precompiles to interact with Warden modules, accessing all core features of Warden Protocol.

For advanced usage of EVM contracts with AI Agents, refer to Build an onchain AI Agent.

WASM contracts​

The x/wasm Warden module allows executing WebAssembly smart contracts developed with CosmWasm and Rust.

Section overview​

  • Examples of Intelligent Apps
    Here you can find a full list of available Intelligent Applications.

  • Set up a Warden account
    Before building an application, you should set up a Warden account (key) on a local chain or a testnet, as shown in this guide. Here you can also find useful node commands for managing keys.

  • Deploy smart contracts on Warden
    Get started with Intelligent Apps: deploy a basic WASM or EVM smart contract on Warden.

  • Call Warden modules in a smart contract
    Call Warden modules in your contract to access Warden-specific features such as managing Spaces and Keychains, creating Rules, getting data from oracles, and so on.

  • Precompiles
    Warden precompiles allow you to call Warden modules in EVM contracts. Browse this section to discover full lists of methods available for each precompile.

  • Build with WardenJS
    Here you'll find information about WardenJS—a tool used for building the frontend part of your application.

Get started​

You can get started with Intelligent Applications by following these steps:

  1. Set up a Warden account on a local chain or on a testnet.
  2. Deploy an EVM contract or a WASM contract.
