# getStakeMinimumDelegation

> 返回最低质押委托金额

## 参数

<ResponseField name="config" type="object" optional>
  包含以下内容的配置对象：

  <ResponseField name="commitment" type="string" optional>
    Commitment 级别（processed、confirmed、finalized）
  </ResponseField>
</ResponseField>

## 响应

<ResponseField name="result" type="number">
  最低质押委托金额（以 lamports 为单位）
</ResponseField>

## 代码示例

### 基本请求

```bash theme={null}
curl https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getStakeMinimumDelegation",
  "params": []
}'
```

### 使用 web3.js

```typescript theme={null}
import { Connection } from '@solana/web3.js';

const connection = new Connection('https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY');

// Get minimum stake delegation
const minDelegation = await connection.getStakeMinimumDelegation();
console.log('Minimum stake delegation:', minDelegation);

// Get minimum stake delegation with analysis
async function getStakeMinimumDelegationWithAnalysis(
  config?: { commitment?: string }
) {
  const minDelegation = await connection.getStakeMinimumDelegation(config);
  
  return {
    minDelegation,
    analysis: {
      inSOL: minDelegation / 1e9, // Convert lamports to SOL
      metadata: {
        timestamp: Date.now(),
        commitment: config?.commitment
      }
    }
  };
}
```

## 注意事项

1. 返回以 lamports 为单位的最低质押委托金额
2. 最低委托金额由网络设置
3. 响应是即时的，因为它从当前状态读取
4. 最低委托金额可能随网络升级而变化
5. 此值对于确定有效的质押金额非常重要

## 最佳实践

1. 根据需求使用适当的 commitment 级别
2. 在适当时缓存结果以减少 RPC 负载
3. 监控最低委托金额的变化
4. 考虑使用 WebSocket 订阅获取实时更新
5. 适当处理网络错误并重试

## 用例

1. **质押委托分析**
   ```typescript theme={null}
   interface StakeDelegationAnalysis {
     minDelegation: number;
     metrics: {
       inSOL: number;
       recommendedMinimum: number;
     };
     metadata: {
       timestamp: number;
       commitment?: string;
     };
   }

   class StakeDelegationAnalyzer {
     private readonly recommendedMultiplier = 1.1; // 10% above minimum
     
     async analyzeStakeDelegation(
       config?: { commitment?: string }
     ): Promise<StakeDelegationAnalysis> {
       const minDelegation = await connection.getStakeMinimumDelegation(config);
       
       return {
         minDelegation,
         metrics: {
           inSOL: minDelegation / 1e9,
           recommendedMinimum: minDelegation * this.recommendedMultiplier
         },
         metadata: {
           timestamp: Date.now(),
           commitment: config?.commitment
         }
       };
     }
   }
   ```

2. **质押委托监控**
   ```typescript theme={null}
   interface StakeDelegationChange {
     previousMinDelegation: number;
     currentMinDelegation: number;
     change: number;
     metadata: {
       timestamp: number;
     };
   }

   class StakeDelegationMonitor {
     private previousMinDelegation: number | null = null;
     
     async monitorStakeDelegation(
       config?: { commitment?: string }
     ): Promise<StakeDelegationChange | null> {
       const currentMinDelegation = await connection.getStakeMinimumDelegation(config);
       
       if (this.previousMinDelegation === null) {
         this.previousMinDelegation = currentMinDelegation;
         return null;
       }
       
       if (this.previousMinDelegation !== currentMinDelegation) {
         const change: StakeDelegationChange = {
           previousMinDelegation: this.previousMinDelegation,
           currentMinDelegation,
           change: currentMinDelegation - this.previousMinDelegation,
           metadata: {
             timestamp: Date.now()
           }
         };
         
         this.previousMinDelegation = currentMinDelegation;
         return change;
       }
       
       return null;
     }
   }
   ```

3. **质押委托规划**
   ```typescript theme={null}
   interface StakeDelegationPlan {
     minDelegation: number;
     recommendations: Array<{
       amount: number;
       description: string;
       inSOL: number;
     }>;
     metadata: {
       timestamp: number;
     };
   }

   class StakeDelegationPlanner {
     private readonly tiers = [
       { multiplier: 1.1, description: 'Minimum recommended' },
       { multiplier: 2, description: 'Standard' },
       { multiplier: 5, description: 'Premium' }
     ];
     
     async planStakeDelegation(
       config?: { commitment?: string }
     ): Promise<StakeDelegationPlan> {
       const minDelegation = await connection.getStakeMinimumDelegation(config);
       
       const recommendations = this.tiers.map(tier => ({
         amount: minDelegation * tier.multiplier,
         description: tier.description,
         inSOL: (minDelegation * tier.multiplier) / 1e9
       }));
       
       return {
         minDelegation,
         recommendations,
         metadata: {
           timestamp: Date.now()
         }
       };
     }
   }
   ```
