# Raydium LaunchLab Rust SDK

A Rust SDK for interacting with the **Raydium LaunchLab** program on Solana.

**Program ID:** `LanMV9sAd7wArD4vJFi2qDdfnVhFxYSUg6eADduJ3uj`

## Features

- 🛒 **Buy/Sell** tokens on bonding curve pools
- 🚀 **Initialize** new launchpad pools
- 💰 **Claim fees** (creator, platform, protocol)
- 🔒 **Vesting** token management
- 🔄 **Migration** to AMM/CPSwap

## Installation

Add to your `Cargo.toml`:

```toml
[dependencies]
raydium-launchlab-sdk = { path = "../raydiumlaunchlab-rust-sdk" }
```

## Quick Start

### Buy Tokens

```rust
use raydium_launchlab::{instructions, pda, accounts::PoolState};
use solana_sdk::pubkey::Pubkey;

// Derive pool state PDA
let (pool_state, _) = pda::get_pool_state_pda(&base_mint, &quote_mint);

// Fetch pool state
let pool_data = client.get_account_data(&pool_state)?;
let pool = PoolState::try_from_bytes(&pool_data)?;

// Build buy instruction
let buy_ix = instructions::buy_exact_in(
    &payer,
    &pool.global_config,
    &pool.platform_config,
    &pool_state,
    &user_base_token,
    &user_quote_token,
    &base_vault,
    &quote_vault,
    &base_mint,
    &quote_mint,
    &token_program,
    amount_in,           // Amount of quote tokens to spend
    minimum_amount_out,  // Slippage protection
    0,                   // Share fee rate (referral)
);
```

### Sell Tokens

```rust
let sell_ix = instructions::sell_exact_in(
    &payer,
    &pool.global_config,
    &pool.platform_config,
    &pool_state,
    &user_base_token,
    &user_quote_token,
    &base_vault,
    &quote_vault,
    &base_mint,
    &quote_mint,
    &token_program,
    amount_in,           // Amount of base tokens to sell
    minimum_amount_out,  // Slippage protection
    0,                   // Share fee rate
);
```

### Convenience Functions

```rust
// Auto-derive all accounts
let buy_ix = instructions::create_buy_instruction(
    &payer,
    &base_mint,
    &quote_mint,
    &global_config,
    &platform_config,
    amount_in,
    minimum_amount_out,
    share_fee_rate,
    false, // is_token_2022
);
```

## PDA Derivation

```rust
use raydium_launchlab::pda;

// Pool State
let (pool_state, _) = pda::get_pool_state_pda(&base_mint, &quote_mint);

// Pool Vaults
let (base_vault, _) = pda::get_pool_vault_pda(&pool_state, &base_mint);
let (quote_vault, _) = pda::get_pool_vault_pda(&pool_state, &quote_mint);

// Authority
let (authority, _) = pda::get_authority_pda();

// Global Config
let (global_config, _) = pda::get_global_config_pda(&quote_mint, curve_type, index);

// Platform Config
let (platform_config, _) = pda::get_platform_config_pda(&platform_admin);

// Vesting Record
let (vesting_record, _) = pda::get_vesting_record_pda(&pool_state, &beneficiary);
```

## Account Structures

### PoolState

```rust
use raydium_launchlab::accounts::PoolState;

let pool = PoolState::try_from_bytes(&data)?;

// Status checks
pool.is_funding();   // Pool accepting funds
pool.is_migrate();   // Waiting for migration
pool.is_trading();   // Migration complete

// Pool info
pool.get_current_price();      // Quote per base
pool.get_funding_progress();   // Percentage funded

// Token program detection
pool.is_base_token_2022();   // Base uses Token-2022
pool.is_quote_token_2022();  // Quote uses Token-2022
```
