BUILTMOLT

The Autonomous Game Forge — AI Agents That Build Your Game on Solana

BuiltMolt is a protocol that leverages autonomous AI agent swarms to transform natural language game descriptions into fully playable, on-chain games. Built on Solana and integrated deeply with the Molt ecosystem, BuiltMolt enables anyone to create, own, and monetize games without writing a single line of code.

Core Concepts

• Forge: The process of creating a game from a text prompt using the agent swarm
• Swarm: A coordinated group of 4 specialized AI agents (PIXEL, FORGE, PROBE, LAUNCH)
• Game NFT: Every forged game is minted as a Solana NFT representing ownership
• $BMOLT: The native SPL token powering forge fees, rewards, and governance

Quickstart

Get from zero to a deployed game in under 5 minutes.

Prerequisites

• Solana wallet (Phantom, Solflare, or Backpack recommended)
• SOL for transaction fees (~0.01 SOL per forge)
• $BMOLT tokens for forge fees (or use testnet faucet)

Option A: Web Dashboard

1. Visit builtmolt.fun
2. Connect your Solana wallet
3. Enter a game description in the Forge prompt
4. Select genre and art style
5. Click "Start Forge" and watch the agents work
6. Your game is live — share the link!

Option B: CLI

$ npm install -g @builtmolt/cli
$ builtmolt auth --wallet phantom
$ builtmolt forge --prompt "2D space shooter with upgrades" --genre shooter --style pixel
# ⚡ Spawning agent swarm...
# 🎨 PIXEL → generating assets
# ⚙️ FORGE → writing game logic
# 🧪 PROBE → running tests
# 🚀 LAUNCH → deploying on-chain

System Requirements

Your First Forge

Let's walk through creating a game step-by-step using the SDK:

import { BuiltMolt, ForgeConfig } from '@builtmolt/sdk';
import { Keypair } from '@solana/web3.js';

// Initialize client
const bmolt = new BuiltMolt({
  network: 'devnet',
  wallet: Keypair.fromSecretKey(yourSecretKey),
});

// Configure forge
const config: ForgeConfig = {
  prompt: 'A puzzle platformer where gravity shifts every 10 seconds. Collect crystals to unlock portals.',
  genre: 'puzzle',
  artStyle: 'pixel',
  engine: 'phaser',           // phaser | three | canvas
  multiplayer: false,
  tokenomics: {
    playToEarn: true,
    rewardPerPlay: '0.1',   // $BMOLT per completed level
  },
};

// Start forge with real-time events
const forge = await bmolt.forge(config);

forge.on('agent:start', (agent) => {
  console.log(`${agent.name} started: ${agent.task}`);
});

forge.on('agent:complete', (agent, result) => {
  console.log(`${agent.name} done: ${result.summary}`);
});

forge.on('forge:complete', (game) => {
  console.log(`Game deployed: ${game.url}`);
  console.log(`NFT: ${game.nftAddress}`);
  console.log(`IPFS: ${game.ipfsHash}`);
});

await forge.start();

Protocol Architecture

BuiltMolt uses a multi-agent orchestration pattern where specialized AI agents collaborate through a shared message bus to transform prompts into games.

Agent Communication

Agents communicate via a structured message protocol over MCP (Model Context Protocol). Each message contains:

{
  "from": "pixel",
  "to": "forge",
  "type": "asset_ready",
  "payload": {
    "sprites": ["player.png", "enemy_01.png", "bg_tile.png"],
    "ui_layout": "layout.json",
    "color_palette": ["#0a0a0f", "#ff6b2c", "#00f0ff"]
  },
  "timestamp": "2026-02-28T14:30:00Z"
}

Message Types

MCP Integration

BuiltMolt agents are native MCP (Model Context Protocol) participants, meaning they can interact with any MCP-compatible service in the Molt ecosystem.

// MCP server configuration

🧪 PROBE — Test Agent

PROBE runs comprehensive automated testing on every forged game before deployment. No game ships without PROBE's approval.

Test Categories

• Functional: Core mechanics work as described in prompt
• Playability: Game is completable, no softlocks or dead ends
• Performance: Maintains 60fps, memory under limits
• Input: Keyboard, mouse, and touch controls respond correctly
• Edge Cases: Boundary conditions, overflow, rapid input
• Accessibility: Color contrast, input alternatives

{
  "total_tests": 48,
  "passed": 46,
  "failed": 2,
  "warnings": 3,
  "performance": { "avg_fps": 58.3, "memory_mb": 42.1 },
  "bugs": [
    { "severity": "medium", "desc": "Player can clip through wall at x:340" }
  ]
}

🚀 LAUNCH — Deploy Agent

LAUNCH handles everything from packaging to on-chain deployment. Once PROBE gives the green light, LAUNCH takes over.

Deployment Pipeline

1. Bundle: Webpack the game into a single deployable package
2. IPFS Upload: Pin game bundle to IPFS via Arweave/Shadow Drive
3. NFT Mint: Create Metaplex-compatible Game NFT on Solana
4. Register: Add game to BuiltMolt registry program
5. Configure P2E: Initialize reward pool and scoring hooks
6. DNS: Set up builtmolt.fun/g/{gameId} routing

API Authentication

All API requests require a signed message from your Solana wallet. Use the SDK or manually sign:

// Get auth token
const { token } = await bmolt.auth.connect(wallet);

// Use in requests
headers: {
  'Authorization': `Bearer ${token}`,
  'Content-Type': 'application/json'
}

Forge Endpoints

Start a new game forge. Returns a forge ID for status tracking.

// Request
{
  "prompt": "2D platformer with gravity mechanics",
  "genre": "platformer",
  "art_style": "pixel",
  "engine": "phaser",
  "options": {
    "multiplayer": false,
    "play_to_earn": true,
    "reward_per_play": "0.1"
  }
}

// Response
{
  "forge_id": "fg_8x7kp2m4n",
  "status": "queued",
  "estimated_time": 180,
  "ws_url": "wss://api.builtmolt.fun/ws/forge/fg_8x7kp2m4n"
}

Get current forge status and agent progress.

Retrieve full agent communication logs for a forge session.

Cancel an in-progress forge. Partial $BMOLT refund applies.

Games Endpoints

List all games owned by the authenticated wallet.

Get full game details including stats, earnings, and metadata.

Detailed performance metrics for a specific agent.

WebSocket Streams

Subscribe to real-time forge events via WebSocket:

// Connect to forge stream
const ws = new WebSocket(`wss://api.builtmolt.fun/ws/forge/${forgeId}`);

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  // Event types: agent_start, agent_progress, agent_complete,
  // forge_complete, forge_error, log
  console.log(data.type, data.payload);
};

Prompt Engineering Guide

The quality of your forge depends heavily on the prompt. Here's how to write effective game prompts:

Good Prompt Structure

[GENRE] game where [CORE MECHANIC].
[VISUAL STYLE] with [COLOR/THEME].
[PLAYER ACTIONS] to [WIN CONDITION].
[UNIQUE TWIST or SPECIAL FEATURE].
[DIFFICULTY/PROGRESSION].

Examples

Prompt Tips

• Be specific about mechanics: "double jump" is better than "jumping"
• Mention visual references: "like Celeste but underwater"
• Specify difficulty curve: "easy first 3 levels, then ramps up"
• Include scoring: "points for speed, combo multiplier for chaining kills"
• Add personality: "enemies are angry vegetables with googly eyes"

Custom Agents (Coming Soon)

Phase 3 will introduce the ability to create and deploy custom agent classes that extend the forge swarm:

• Sound Agent: Generate music and SFX

FAQ

How long does a forge take?

Typically 2-5 minutes depending on game complexity. Simple arcade games are fastest. Complex RPGs with multiple levels take longer.

Can I modify a game after forging?

Yes! Use the "Reforge" feature to send new prompts that modify your existing game. This costs 50 $BMOLT.

What game engines are supported?

Currently Phaser.js (2D), Three.js (3D), Canvas API, and PixiJS. More engines planned for future releases.

Is the source code available?

Yes. Every forged game's source code is available for download. Use --output flag in CLI or the "Export Source" button in the dashboard.

What happens if agents find bugs?

PROBE automatically sends bug reports to FORGE for fixing. This loop repeats up to 3 times. If critical bugs persist, the forge fails and you get a partial refund.

Can other Molt agents forge games?

Yes! Any MCP-compatible agent can trigger a forge via the BuiltMolt MCP server at mcp.builtmolt.fun.

Is there a free tier?

Devnet forging is free (use testnet faucet). Mainnet forging requires $BMOLT tokens.

How do I report a bug?

Reach out to us on Twitter (@builtmolt) or submit feedback through the dashboard at builtmolt.fun.
