🛠️ Installation

Prerequisites

• Rust 1.70+
• Solana CLI 1.91.8+
• Anchor Framework 0.29.0+

Setup

# Clone the repository
git clone https://github.com/Tronzit-Veca/Pumpfun-Smart-Contract.git
cd pumpfun-smart-contract
Install dependencies
npm install
Build the program
anchor build
Deploy to devnet
anchor deploy --provider.cluster devnet

📖 Usage

Basic LP Operations

import { Connection, PublicKey } from '@solana/web3.js';
import { Program } from '@coral-xyz/anchor';
// Initialize connection const connection = new Connection('https://api.devnet.solana.com');
// Add virtual LP await program.methods   .addVirtualLp(amount, tokenMint)   .accounts({     user: wallet.publicKey,     pool: poolAddress,   })   .rpc();
// Remove virtual LP await program.methods   .removeVirtualLp(amount, tokenMint)   .accounts({     user: wallet.publicKey,     pool: poolAddress,   })   .rpc();

Raydium Pool Creation

// Create Raydium pool with CPI calls
await program.methods
  .createRaydiumPool(
    tokenAMint,
    tokenBMint,
    initialLiquidity
  )
  .accounts({
    authority: wallet.publicKey,
    raydiumProgram: raydiumProgramId,
  })
  .rpc();

🏗️ Architecture

The smart contract is built using the Anchor framework and consists of:

• State Management: Comprehensive state structures for LP pools
• Instruction Modules: Modular instruction handlers for different operations
• Error Handling: Custom error types for better debugging
• Constants: Centralized configuration management

Key Components

• state.rs: Core state structures and account definitions
• instructions/: Modular instruction handlers
• utils/: Utility functions and helpers
• errors.rs: Custom error definitions
• consts.rs: Configuration constants
