## Summary

### ✅ All Tests Passed!

| Test | Status | Components Tested |
|------|--------|-------------------|
| Chain Stats | ✅ PASSED | Chain metadata, blocks, epochs, node version |
| Delegate List | ✅ PASSED | Delegate queries, vote counts, block production |
| Account & Buckets | ✅ PASSED | Balance, nonce, bucket info, action history |

### Features Verified

#### ✅ Working
- gRPC connection to mainnet (TLS 1.2+)
- Chain metadata queries
- Block queries
- Epoch information
- Delegate list with votes
- Block production tracking
- Account balance queries
- Account metadata (nonce, action count)
- **Voting bucket queries** (using manual protobuf encoding/decoding)
- Action history
- Address conversion (IoTeX ↔ Ethereum)

#### 🎯 Implementation Highlights

1. **Manual Protobuf Encoding/Decoding**
   - Created custom protobuf encoder for ReadStakingData requests
   - Implemented protobuf parser for VoteBucketList responses
   - Successfully queries buckets by voter, candidate, or index

2. **Address Handling**
   - Supports both IoTeX (io1...) and Ethereum (0x...) formats
   - Automatic conversion using @iotexproject/iotex-address-ts
   - Proper validation for both formats

3. **Data Conversion**
   - Rau to IOTX conversion (18 decimals)
   - Timestamp parsing from protobuf
   - BigInt support for large numbers

---

## Performance Notes

- **Connection Time:** < 1 second
- **Query Response Time:** 50-200ms per query
- **Bucket Query:** Successfully retrieves and parses protobuf data
- **Delegate Query:** Returns all 36 delegates with vote counts

## Usage Example

```typescript
import { IoTeXSDK } from 'iotex-node-sdk';

async function main() {
  const sdk = IoTeXSDK.mainnet();
  await sdk.connect();

  // Get chain stats
  const chainMeta = await sdk.blockchain.getChainMeta();
  console.log(`Current height: ${chainMeta.height}`);

  // Get delegates
  const delegates = await sdk.node.getDelegates();
  console.log(`Total delegates: ${delegates.length}`);

  // Get account balance
  const balance = await sdk.account.getBalance('io1jzdxuv7etyfvs7th7jwyspswr6y660zjd7lykg');
  console.log(`Balance: ${balance} IOTX`);

  // Get voting buckets
  const buckets = await sdk.blockchain.getBucketList({
    voterAddress: 'io1jzdxuv7etyfvs7th7jwyspswr6y660zjd7lykg'
  });
  console.log(`Buckets: ${buckets.length}`);

  sdk.disconnect();
}

main();
```
