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
  • 💰 Lending & Borrowing: Collateralized lending protocol with liquidations
  • 🔒 Staking & Rewards: Time-based staking with proportional reward distribution
  • 🌾 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

Quote Interest Rate

stellar-defi-cli quote-rate --utilization-bps 8000

Check if a Position is Liquidatable

stellar-defi-cli check-liquidation \
  --borrower "GCBORROWER456" \
  --debt-asset "USDC" \
  --collateral-asset "XLM" \
  --debt-price 1000000000000000000 \
  --collateral-price 500000000000000000

Liquidate an Undercollateralized Position

stellar-defi-cli liquidate \
  --liquidator "GCLIQUIDATOR123" \
  --borrower "GCBORROWER456" \
  --debt-asset "USDC" \
  --collateral-asset "XLM" \
  --repay-amount 1000000000000000000000 \
  --debt-price 1000000000000000000 \
  --collateral-price 500000000000000000 \
  --dry-run

For detailed documentation on liquidation commands, see CLI_LIQUIDATION.md.

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"

Stake Tokens

stellar-defi-cli stake \
  --contract-id "STAKING_CONTRACT_ID" \
  --amount 1000

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(())
}

Example: Stake Tokens and Earn Rewards

use soroban_sdk::{Env, Address};
use stellar_defi_toolkit::StakingContract;

fn main() {
    let env = Env::default();
    env.mock_all_auths();
    
    let admin = Address::generate(&env);
    let user = Address::generate(&env);
    
    // Initialize staking contract
    let staking = StakingContractClient::new(&env, &contract_id);
    staking.initialize(
        &admin,
        &staking_token_address,
        &reward_token_address,
        &17280, // 1 day reward period
    );
    
    // Set rewards
    staking.notify_reward_amount(&admin, &10_000_000_000);
    
    // User stakes tokens
    staking.stake(&user, &1_000_000_000);
    
    // Check earned rewards
    let earned = staking.get_earned(&user);
    println!("Earned rewards: {}", earned);
    
    // Claim rewards
    staking.claim_rewards(&user);
}
