```

## Usage Examples

### 1. Logs Subscription - Monitor Token Trading

```rust
use sol_trade_sdk::{common::pumpfun::logs_events::PumpfunEvent, grpc::YellowstoneGrpc};
use solana_sdk::signature::Keypair;

// Create gRPC client with Yellowstone
let grpc_url = "https://solana-yellowstone-grpc.publicnode.com:443";
let x_token = None; // Optional auth token
let client = YellowstoneGrpc::new(grpc_url.to_string(), x_token)?;

// Define callback function
let callback = |event: PumpfunEvent| match event {
    PumpfunEvent::NewDevTrade(trade_info) => {
        println!("Received new dev trade event: {:?}", trade_info);
    }
    PumpfunEvent::NewToken(token_info) => {
        println!("Received new token event: {:?}", token_info);
    }
    PumpfunEvent::NewUserTrade(trade_info) => {
        println!("Received new trade event: {:?}", trade_info);
    }
    PumpfunEvent::NewBotTrade(trade_info) => {
        println!("Received new bot trade event: {:?}", trade_info);
    }
    PumpfunEvent::Error(err) => {
        println!("Received error: {}", err);
    }
};

client.subscribe_pumpfun(callback, None).await?;
```

### 2. Initialize SolanaTrade Instance

```rust
use std::{str::FromStr, sync::Arc};

use sol_trade_sdk::{
    common::{AnyResult, PriorityFee, TradeConfig}, 
    swqos::{SwqosConfig, SwqosRegion, SwqosType}, 
    SolanaTrade
};
use solana_client::rpc_client::RpcClient;
use solana_sdk::{commitment_config::CommitmentConfig, pubkey::Pubkey, signature::Keypair};

// Configure priority fees
let priority_fee = PriorityFee {
    unit_limit: 190000,
    unit_price: 1000000,
    rpc_unit_limit: 500000,
    rpc_unit_price: 500000,
    buy_tip_fee: 0.001,
    buy_tip_fees: vec![0.001, 0.002],
    sell_tip_fee: 0.0001,
};

// Configure multiple swqos in single region, can send transactions concurrently
let swqos_configs = vec![
    SwqosConfig::new(None, None, SwqosType::Jito, SwqosRegion::Frankfurt),
    SwqosConfig::new(None, Some("your auth_token".to_string()), SwqosType::ZeroSlot, SwqosRegion::Frankfurt),
    SwqosConfig::new(None, Some("your auth_token".to_string()), SwqosType::Temporal, SwqosRegion::Frankfurt),
];

let rpc_url = "https://mainnet.helius-rpc.com/?api-key=xxxxxx".to_string();

// Define sdk configuration
let trade_config = TradeConfig {
    rpc_url: rpc_url.clone(),
    commitment: CommitmentConfig::confirmed(),
    priority_fee,
    swqos_configs,
    lookup_table_key: None,
};

// Create SolanaTrade instance
let payer = Keypair::from_base58_string("your_private_key");
let solana_trade_client = SolanaTrade::new(Arc::new(payer), trade_config).await;
```

### 3. Buy Tokens

### 3.1 Buy Tokens --- Sniping
```rust
use solana_sdk::{pubkey::Pubkey, hash::Hash};
use std::sync::Arc;
use sol_trade_sdk::accounts::BondingCurveAccount;

let mint_pubkey = Pubkey::from_str("token_address")?;
let creator = Pubkey::from_str("creator_address")?;
let recent_blockhash = Hash::default(); // Get latest blockhash
let buy_sol_cost = 50000; // 0.00005 SOL
let slippage_basis_points = Some(100); // 1%

// Sniping buy (quick purchase when new token launches)
let dev_buy_token = 100_000; // Test value
let dev_cost_sol = 10_000; // Test value
let bonding_curve = BondingCurveAccount::new(&mint_pubkey, dev_buy_token, dev_cost_sol, creator);

solana_trade_client.sniper_buy(
    mint_pubkey,
    creator,
    buy_sol_cost,
    slippage_basis_points,
    recent_blockhash,
    Some(Arc::new(bonding_curve)),
).await?;

// Buy with MEV protection using tips
solana_trade_client.sniper_buy_with_tip(
    mint_pubkey,
    creator,
    buy_sol_cost,
    slippage_basis_points,
    recent_blockhash,
    Some(Arc::new(bonding_curve)),
    None, // Custom tip
).await?;
```

### 3.2 Buy Tokens --- Copy Trading
```rust
use solana_sdk::{pubkey::Pubkey, hash::Hash};
use std::sync::Arc;
use sol_trade_sdk::accounts::BondingCurveAccount;
use sol_trade_sdk::{constants::{pumpfun::global_constants::TOKEN_TOTAL_SUPPLY, trade_type::COPY_BUY}, pumpfun::common::get_bonding_curve_pda};

let mint_pubkey = Pubkey::from_str("token_address")?;
let creator = Pubkey::from_str("creator_address")?;
let recent_blockhash = Hash::default(); // Get latest blockhash
let buy_sol_cost = 50000; // 0.00005 SOL
let slippage_basis_points = Some(100); // 1%

// Copy trading buy
let dev_buy_token = 100_000; // Test value
let dev_cost_sol = 10_000; // Test value
// trade_info comes from pumpfun parsed data, refer to section 1. Logs Subscription above
let bonding_curve = Some(Arc::new(BondingCurveAccount {
    discriminator: 0,
    account: get_bonding_curve_pda(&trade_info.mint).unwrap(),
    virtual_token_reserves: trade_info.virtual_token_reserves,
    virtual_sol_reserves: trade_info.virtual_sol_reserves,
    real_token_reserves: trade_info.real_token_reserves,
    real_sol_reserves: trade_info.real_sol_reserves,
    token_total_supply: TOKEN_TOTAL_SUPPLY,
    complete: false,
    creator: Pubkey::from_str(&creator).unwrap(),
}));

solana_trade_client.buy(
    mint_pubkey,
    creator,
    buy_sol_cost,
    slippage_basis_points,
    recent_blockhash,
    Some(Arc::new(bonding_curve)),
    "pumpfun".to_string(), 
).await?;

// Buy with MEV protection using tips
solana_trade_client.buy_with_tip(
    mint_pubkey,
    creator,
    buy_sol_cost,
    slippage_basis_points,
    recent_blockhash,
    Some(Arc::new(bonding_curve)),
    "pumpfun".to_string(), 
    None, // Custom tip
).await?;
```

### 4. Sell Tokens

```rust
// Sell by amount
solana_trade_client.sell_by_amount_with_tip(
    mint_pubkey,
    creator,
    1000000, // token amount
    recent_blockhash,
    "pumpfun".to_string(), // trading platform
).await?;

// Sell by percentage
solana_trade_client.sell_by_percent_with_tip(
    mint_pubkey,
    creator,
    50,      // percentage (50%)
    2000000, // total token amount
    recent_blockhash,
    "pumpfun".to_string(), // trading platform
).await?;
```

### 5. Get Price and Balance Information

```rust
// Get current token price
let price = solana_trade_client.get_current_price(&mint_pubkey).await?;
println!("Current price: {}", price);

// Get SOL balance
let sol_balance = solana_trade_client.get_payer_sol_balance().await?;
println!("SOL balance: {} lamports", sol_balance);

// Get token balance
let token_balance = solana_trade_client.get_payer_token_balance(&mint_pubkey).await?;
println!("Token balance: {}", token_balance);

// Get liquidity information
let sol_reserves = solana_trade_client.get_real_sol_reserves(&mint_pubkey).await?;
println!("SOL reserves: {} lamports", sol_reserves);
```

### 6. PumpSwap Subscription - Monitor AMM Events

```rust
use sol_trade_sdk::{common::pumpswap::logs_events::PumpSwapEvent, grpc::YellowstoneGrpc};

let grpc_url = "https://solana-yellowstone-grpc.publicnode.com:443";
let x_token = None;
let client = YellowstoneGrpc::new(grpc_url.to_string(), x_token)?;

// Define callback function for PumpSwap events
let callback = |event: PumpSwapEvent| match event {
    PumpSwapEvent::Buy(buy_event) => {
        println!("buy_event: {:?}", buy_event);
    }
    PumpSwapEvent::Sell(sell_event) => {
        println!("sell_event: {:?}", sell_event);
    }
    PumpSwapEvent::CreatePool(create_event) => {
        println!("create_event: {:?}", create_event);
    }
    PumpSwapEvent::Deposit(deposit_event) => {
        println!("deposit_event: {:?}", deposit_event);
    }
    PumpSwapEvent::Withdraw(withdraw_event) => {
        println!("withdraw_event: {:?}", withdraw_event);
    }
    PumpSwapEvent::Disable(disable_event) => {
        println!("disable_event: {:?}", disable_event);
    }
    PumpSwapEvent::UpdateAdmin(update_admin_event) => {
        println!("update_admin_event: {:?}", update_admin_event);
    }
    PumpSwapEvent::UpdateFeeConfig(update_fee_event) => {
        println!("update_fee_event: {:?}", update_fee_event);
    }
    PumpSwapEvent::Error(err) => {
        println!("error: {}", err);
    }
};

// Subscribe to PumpSwap events
println!("Monitoring PumpSwap events, press Ctrl+C to stop...");
client.subscribe_pumpswap(callback).await?;
```

### 7. PumpSwap Trading Operations

```rust
use std::sync::Arc;
use solana_sdk::{pubkey::Pubkey, hash::Hash, signature::Keypair};
use solana_client::rpc_client::RpcClient;

let creator = Pubkey::from_str("11111111111111111111111111111111")?; // dev account
let buy_sol_cost = 500_000; // 0.0005 SOL
let slippage_basis_points = Some(100);
let rpc = RpcClient::new(cluster.rpc_url);
let recent_blockhash = rpc.get_latest_blockhash().unwrap();
let trade_platform = "pumpswap".to_string();
let mint_pubkey = Pubkey::from_str("YOUR_TOKEN_MINT")?; // token mint

println!("Buying tokens from PumpSwap...");
solana_trade_client
    .buy(
        mint_pubkey,
        creator,
        buy_sol_cost,
        slippage_basis_points,
        recent_blockhash,
        None,
        trade_platform.clone(),
    )
    .await?;

// Sell 30% * amount_token quantity
solana_trade_client
    .sell_by_percent(
        mint_pubkey,
        creator,
        30,      // percentage (30%)
        100,     // total token amount
        recent_blockhash,
        trade_platform.clone(),
    )
    .await?;
```

### 8. PumpSwap Pool Information

```rust
use solana_sdk::pubkey::Pubkey;

let pool_address = Pubkey::from_str("pool_address")?;

// Get current price from PumpSwap pool
let price = solana_trade_client.get_current_price_with_pumpswap(&pool_address).await?;
println!("PumpSwap pool price: {}", price);

// Get SOL reserves in PumpSwap pool
let sol_reserves = solana_trade_client.get_real_sol_reserves_with_pumpswap(&pool_address).await?;
println!("PumpSwap SOL reserves: {} lamports", sol_reserves);

// Get token balance in PumpSwap pool
let token_balance = solana_trade_client.get_payer_token_balance_with_pumpswap(&pool_address).await?;
println!("PumpSwap token balance: {}", token_balance);
```
