## 🛠️ Implementation
### 1. Setting up Address Lookup Table Cache
The SDK provides a global cache to manage address lookup tables:
```rust
use sol_trade_sdk::common::address_lookup_cache::AddressLookupTableCache;
use solana_sdk::pubkey::Pubkey;
use std::str::FromStr;
/// Setup lookup table cache
async fn setup_lookup_table_cache(

.set_address_lookup_table(client, &lookup_table_address)
.await
.map_err(|e| anyhow::anyhow!("Failed to set address lookup table: {}", e))?;
Ok(())
}
```
### 2. Using Lookup Tables in Trade Parameters
Include lookup tables in your trade parameters:
```rust
// Initialize lookup table
let lookup_table_key = Pubkey::from_str("your_lookup_table_address_here").unwrap();
setup_lookup_table_cache(client.rpc.clone(), lookup_table_key).await?;

1. **Lookup Table Address**: Must provide a valid address lookup table address

4. **Network Specific**: Lookup tables are network-specific (mainnet/devnet/testnet)

## 🛠️ 实现方法
### 1. 设置地址查找表缓存
SDK 提供了一个全局缓存来管理地址查找表：
```rust
use sol_trade_sdk::common::address_lookup_cache::AddressLookupTableCache;
use solana_sdk::pubkey::Pubkey;
use std::str::FromStr;
/// 设置查找表缓存
async fn setup_lookup_table_cache(

.await
.map_err(|e| anyhow::anyhow!("Failed to set address lookup table: {}", e))?;
Ok(())
}
```

在您的交易参数中包含查找表：
```rust
// 初始化查找表
let lookup_table_key = Pubkey::from_str("your_lookup_table_address_here").unwrap();

1. **查找表地址**: 必须提供有效的地址查找表地址
2. **缓存管理**: SDK 自动管理查找表缓存
3. **RPC 兼容性**: 确保您的 RPC 提供商支持查找表
4. **网络**: 查找表是特定于网络的（主网/开发网/测试网）
5. **测试**: 在主网使用前请务必在开发网测试
