Stellar DeFi Toolkit 🚀

A comprehensive DeFi toolkit for building decentralized finance applications on the Stellar blockchain using Soroban smart contracts.

✨ Features

• 🪙 Token Contracts: Complete ERC-20-like token implementation on Stellar
• 💧 Liquidity Pools: Automated market maker (AMM) liquidity pools
• 🌾 Yield Farming: Staking and reward distribution mechanisms
• 🌉 Cross-chain Bridges: Asset transfer between different blockchains
• 🏛️ Governance: Decentralized governance and voting systems
• 📊 Analytics: Real-time DeFi protocol analytics and monitoring
• 🛠️ Developer Tools: CLI tools and SDK for easy development

🚀 Quick Start

Prerequisites

• Rust 1.70.0 or higher
• Stellar CLI tools
• Soroban CLI

Installation

From Crates.io (Coming Soon)

cargo install stellar-defi-toolkit

From Source

git clone https://github.com/yourusername/stellar-defi-toolkit.git
cd stellar-defi-toolkit
cargo build --release

📖 Usage

CLI Usage

Deploy a New Token

stellar-defi-cli deploy-token \
  --name "My Token" \
  --symbol "MTK" \
  --supply 1000000

Create a Liquidity Pool

stellar-defi-cli create-pool \
  --token-a "TOKEN_A_CONTRACT_ID" \
  --token-b "TOKEN_B_CONTRACT_ID"

Get Contract Information

stellar-defi-cli get-info \
  --contract-id "CONTRACT_ID"

Library Usage

Add this to your Cargo.toml:

[dependencies]
stellar-defi-toolkit = "0.1.0"
tokio = { version = "1.0", features = ["full"] }

Example: Deploy a Token Contract

use stellar_defi_toolkit::{TokenContract, StellarClient};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let client = StellarClient::new().await?;
    
    let token = TokenContract::new("My Token".to_string(), "MTK".to_string(), 1000000);
    let contract_id = token.deploy(&client).await?;
    
    println!("Token deployed with contract ID: {}", contract_id);
    Ok(())
}

Example: Create a Liquidity Pool

use stellar_defi_toolkit::{LiquidityPoolContract, StellarClient};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let client = StellarClient::new().await?;
    
    let pool = LiquidityPoolContract::new(
        "TOKEN_A_CONTRACT_ID".to_string(),
        "TOKEN_B_CONTRACT_ID".to_string()
    );
    let contract_id = pool.deploy(&client).await?;
    
    println!("Liquidity pool created with contract ID: {}", contract_id);
    Ok(())
}
