Token Launchpad

Fair launch token launchpad platform with bonding curves and liquidity bootstrapping on Solana.

Overview

A decentralized token launchpad enabling fair token launches with bonding curve mechanics. Similar to pump.fun but with additional features for creator control and investor protection.

Features

• Bonding curve token sales
• Automatic liquidity migration to Raydium
• Customizable curve parameters
• Anti-snipe protection
• Creator vesting schedules
• Real-time price charts
• Mobile-responsive UI

How It Works

1. Create Token: Deploy a new token with custom metadata
2. Bonding Curve: Token price follows a bonding curve formula
3. Trading: Users buy/sell against the curve
4. Migration: When threshold is reached, liquidity migrates to Raydium
5. Trading Continues: Token becomes freely tradeable on DEX

Bonding Curve Math

Price = Base × (1 + Supply / Scale)^Exponent

Default parameters:
- Base: 0.00001 SOL
- Scale: 800,000,000 tokens
- Exponent: 1.5

Accounts

#[account]
pub struct BondingCurve {
    pub creator: Pubkey,
    pub mint: Pubkey,
    pub vault: Pubkey,
    pub virtual_sol_reserves: u64,
    pub virtual_token_reserves: u64,
    pub real_sol_reserves: u64,
    pub real_token_reserves: u64,
    pub migration_threshold: u64,
    pub is_migrated: bool,
    pub bump: u8,
}

Client SDK

import { LaunchpadClient } from './src/lib/client';

const client = new LaunchpadClient(connection, wallet);

// Create new token
const { mint, bondingCurve } = await client.createToken({
  name: 'My Token',
  symbol: 'MTK',
  description: 'An example token',
  image: 'https://...',
  migrationThreshold: 85 * LAMPORTS_PER_SOL, // 85 SOL
});

// Buy tokens
const result = await client.buy({
  bondingCurve,
  solAmount: 0.1 * LAMPORTS_PER_SOL,
  minTokens: 1000000,
});

// Sell tokens
await client.sell({
  bondingCurve,
  tokenAmount: 500000,
  minSol: 0.04 * LAMPORTS_PER_SOL,
});

// Get price
const price = await client.getPrice(bondingCurve);
console.log(`Current price: ${price} SOL`);

Fee Structure

Fee	Amount	Recipient
Trade Fee	1%	Platform
Creator Fee	Optional	Creator
Migration Fee	0.5 SOL	Platform

Security

• Audited smart contracts
• Anti-bot measures (min/max buy)
• Creator vesting to prevent rugs
• Liquidity locked on migration
