# Wagmi Chain Configuration - Verified ✅

**Status**: ✅ **CORRECT APPROACH CONFIRMED**

---

## ✅ Current Implementation (Correct)

### Import Statement
```typescript
import { defineChain } from 'viem'
```

**Why this is correct**:
- Wagmi v2 is built on top of viem
- `defineChain` is exported from `viem` (not `wagmi/chains`)
- This is the official approach for custom chains in wagmi v2

### Chain Definition
```typescript
const chain138 = defineChain({
  id: 138,
  name: 'DeFi Oracle Meta Mainnet',
  network: 'chain138',
  nativeCurrency: {
    decimals: 18,
    name: 'Ether',
    symbol: 'ETH',
  },
  rpcUrls: {
    default: {
      http: [rpcUrl138],
    },
    public: {
      http: [rpcUrl138],
    },
  },
  blockExplorers: {
    default: {
      name: 'DBIS Explorer',
      url: 'https://explorer.d-bis.org',
    },
  },
})
```

**Structure**: ✅ Correct for viem/wagmi v2

## ✅ Verification Results

### 1. Import Verification
- ✅ `defineChain` exists in `viem` package
- ✅ Import path is correct: `import { defineChain } from 'viem'`
- ✅ Function works correctly (tested)

### 2. Chain Definition
- ✅ Structure matches viem's Chain type
- ✅ All required fields present
- ✅ Compatible with wagmi v2

### 3. Wagmi Config
- ✅ Chain added to `chains` array
- ✅ Transport configured correctly
- ✅ Connectors configured

## 📚 Official Documentation

According to wagmi v2 and viem documentation:
- Custom chains use `defineChain` from `viem`
- `wagmi/chains` only exports predefined chains
- This is the standard approach

---

## ✅ Status

- ✅ Import: Correct (`from 'viem'`)
- ✅ Function: Works correctly
- ✅ Structure: Valid chain definition
- ✅ Integration: Properly configured in wagmi
- ✅ Server: Running and responding

---

## 🎯 Conclusion

**The current implementation is correct and follows wagmi v2 best practices.**

No changes needed. The configuration is:
- ✅ Using the right import (`viem`)
- ✅ Using the correct function (`defineChain`)
- ✅ Properly structured chain definition
- ✅ Correctly integrated with wagmi config

---

**✅ Configuration Verified - All Correct!**
