What is Smart Assembly?

Smart Assembly (SA) is the programmable system at the heart of Eve Frontier. Every structure, gate, and interactive object in the game world is a Smart Assembly — a configurable entity that runs on-chain logic.

Why It Matters

Unlike traditional MMOs where game objects are static and server-controlled, Eve Frontier's Smart Assemblies are owned and programmable by players. This means:

• Gates can enforce custom access rules
• Structures can charge fees, track visitors, or trigger events
• Resources can be distributed according to player-defined logic

The Building Blocks

Every Smart Assembly is composed of:

// A minimal Smart Assembly system
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

import { System } from "@latticexyz/world/src/System.sol";

contract MyFirstSystem is System {
  function execute() public {
    // Your logic here
  }
}

What You'll Learn

In this tutorial series, you'll go from zero to building functional Smart Assemblies. We'll cover:

• The MUD framework and how it powers Eve Frontier
• Writing your first system
• Reading and writing on-chain tables
• Deploying to the Eve Frontier world
• Testing your assemblies locally
