Technical Architecture

LaunchFun is built on a modern, scalable architecture designed for high performance and security on the Solana blockchain.

Technology Stack

  • Frontend: Next.js 15, TypeScript, Tailwind CSS, Solana Wallet Adapter.
  • Backend: Cloudflare Workers, D1 (SQLite), R2 (Object Storage).
  • Blockchain: Solana, Anchor Framework, SPL Token Program, Metaplex.
  • Data Sources: DexScreener, CoinGecko, Solana RPC, IPFS/Pinata.

Core Components

1. Intent Engine

The heart of LaunchFun. Aggregates user trading intents and optimizes execution for best prices.

Intent Structure
interface Intent {
  user: PublicKey;
  action: "BUY" | "SELL";
  token: PublicKey;
  amount: number;
  conviction: "LOW" | "MEDIUM" | "HIGH";
  timestamp: number;
  status: "POOLING" | "EXECUTING" | "FILLED";
}

2. Delayed Reality Launch (DRL)

Anti-bot mechanism that introduces time delays to prevent MEV exploitation.

DRL Config
const DRL_CONFIG = {
  launchDelay: 300,      // 5 minutes
  priceDiscoveryPause: true,
  botDetection: true,
  fairLaunchMode: true
};

3. Bonding Curve AMM

Automated market maker ensuring fair price discovery based on supply.

Formula
price = basePrice * (1 + supply / maxSupply)^2
