Photon Swap

A TypeScript implementation for executing swaps on Solana using the Photon Protocol with PumpFun integration.

Overview

Photon Swap is a decentralized exchange (DEX) integration that facilitates token swaps on the Solana blockchain. It specifically implements PumpFun swaps with built-in fee management through the Photon protocol.

Features

• Photon Protocol Integration: Implements swap functionality using the Photon Program (BSfD6SHZigAfDWSjzD5Q41jw8LmKwtmjskPH9XW1mrRW)
• PumpFun Support: Direct integration with PumpFun protocol for token swaps
• Automatic Token Account Creation: Creates Associated Token Accounts (ATAs) if they don't exist
• Fee Management:
  • Handles Photon protocol fees
  • Includes BloxRoute integration for transaction routing
  • Implements priority fees for better transaction success rates
• Transaction Optimization:
  • Compute budget management
  • Priority fee settings
  • Transaction simulation before submission

Key Components

• Program IDs:

  • Photon Program: BSfD6SHZigAfDWSjzD5Q41jw8LmKwtmjskPH9XW1mrRW
  • PumpFun Program: 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P

  • PumpFun Fee Recipient: 62qc2CNXwrYqQScmEdiZFFAnJR262PxWEwNQtxfafNgV
  • BloxRoute Fee: 0.06 SOL per transaction

Prerequisites

• Node.js
• TypeScript
• Solana Web3.js
• SPL Token Library
• BloxRoute Solana Trader Client

Environment Variables

SOLANA_PRIVATE_KEY=<your-private-key>

Installation

npm install

Usage

1. Set up your environment variables in .env
2. Run the application:

npm dev

Transaction Flow

1. Initialization:

   • Creates keypair from private key
   • Establishes connection to Solana network
   • Validates token accounts

2. Swap Execution:

   • Sets compute budget and priority fees
   • Creates Associated Token Account if needed
   • Constructs swap instruction with Photon protocol
   • Handles fee transfers
   • Simulates transaction
   • Submits and confirms transaction

Security Considerations

• Private keys should be securely stored in environment variables
• Transaction simulation is performed before submission
• Compute budget is properly configured to prevent transaction failures
• Slippage protection is implemented (default: 1000 basis points)

Dependencies
