✨ Features

• Real-time Monitoring: Subscribes to the Solana blockchain and listens for specific transaction logs.
• Token Detection: Identifies new tokens associated with a particular owner address.
• Customizable Filters: Easily modify the code to monitor different addresses or token criteria.
• Lightweight and Efficient: Built with asynchronous Rust for high performance.
• Sniper robot: Automatically buys the token when it appears.

📋 Prerequisites

• Rust: Make sure you have Rust installed. If not, download it from rust-lang.org.
• Tokio Runtime: This project uses asynchronous programming, so the Tokio runtime is required.
• Solana Client Libraries: Uses solana_client and related crates.

🔧 Installation

1. Clone the Repository

   bashCopy
   git clone https://github.com/CodeCat-maker/solana_meme
   cd solana_meme

2. Install Dependencies

   bashCopy
   cargo build

🚀 Usage

1. Configure API Key
   Replace the placeholder API key in the code with your actual API key from Helius

   rustCopy
   let env = Env {
       ws_url: Url::parse(
           "wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY",
       )?,
   };
   ...
       let rpc_client = rpc_client::RpcClient::new(
        "https://mainnet.helius-rpc.com/?api-key=Your_API_KEY".to_string(),
    );

2. Run the Program

   bashCopy
   cargo run

3. Monitor Output

   The application will begin monitoring and output messages when new tokens are detected.

🛠️ How It Works

• Subscription to Logs: The program subscribes to transaction logs on the Solana mainnet where a specific public key is mentioned.

• Transaction Filtering: It filters transactions to find those that involve the specified owner address and exclude the native SOL token.

• Token Detection: When a matching transaction is found, it prints out the mint address of the new token.

Key Components

• PubsubClient: Used for subscribing to the Solana WebSocket for real-time updates.

• RpcClient: Allows fetching detailed transaction data from the Solana RPC API.

• Filters and Configs: Customized filters to narrow down the transactions of interest.
