A comprehensive yield farming client for Ethereum blockchain, implemented in both Rust and Go. This project provides robust, production-ready tools for interacting with DeFi yield farming protocols.

Yield farming, also known as liquidity mining, is a process where users earn rewards by providing liquidity to decentralized exchanges (DEXs) or other blockchain platforms. Users deposit their cryptocurrency assets into liquidity pools and earn rewards based on:

• Amount of liquidity provided
• Fees generated by the DEX
• Additional reward tokens
• Protocol incentives

Yield farming involves significant risks:

• Cryptocurrency price volatility
• Smart contract vulnerabilities
• Impermanent loss
• Potential scams or rug pulls
• Regulatory uncertainty

Always conduct thorough research and understand the risks before participating. This software is provided "as is" without warranties.

4. Run the application:

   cargo run

use blockchain_yield_farming::YieldFarmingClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize client
    let client = YieldFarmingClient::new(
        "https://mainnet.infura.io/v3/YOUR_PROJECT_ID",
        contract_address,
        contract_abi
    )?;
    
    // Get pool information
    let tvl = client.get_total_value_locked().await?;
    let apy = client.get_current_apy().await?;
    
    println!("Total Value Locked: {} wei", tvl);
    println!("Current APY: {}%", apy);
    
    // Deposit tokens
    let amount = U256::from(1000000000000000000u64); // 1 ETH
    let tx_hash = client.deposit(amount, account).await?;
    
    // Wait for confirmation
    let receipt = client.wait_for_transaction(tx_hash).await?;
    println!("Transaction confirmed in block {}", receipt.block_number);
    
    Ok(())
