- ✅ Includes proper tag definitions

---

### 3. Validation ✅

**ChainID 138 Token List**:
```
✅ Token list is valid!
📋 Token List Info:
   Name: DBIS Chain 138 Token List
   Version: 1.2.0
   Timestamp: 2026-01-26T00:00:00.000Z
   Tokens: 6
```

**Ethereum Mainnet Token List**:
```
✅ Token list is valid!
📋 Token List Info:
   Name: Ethereum Mainnet Token List
   Version: 1.0.0
   Timestamp: 2026-01-26T00:00:00.000Z
   Tokens: 1
```

**Validation Results**:
- ✅ All addresses are EIP-55 checksummed
- ✅ All chain IDs are correct
- ✅ All decimals are valid
- ✅ Schema validation passed
- ✅ Tag descriptions match schema pattern
- ✅ All required fields present

---

### 4. Enhanced Validation Script ✅

**File**: `token-lists/scripts/validate-token-list.js`

**Improvements**:
- ✅ Made chain ID validation flexible (no longer hardcoded to 138)
- ✅ Detects chain ID from token list automatically
- ✅ Validates all tokens have consistent chain ID
- ✅ Supports `--chain-id` flag for strict validation when needed

---

### 5. On-Chain Verification ⚠️

**Status**: Skipped (RPC endpoints not accessible from current environment)

**Note**: On-chain verification requires network access to ChainID 138 RPC endpoints. The token list structure and addresses are validated and correct. On-chain verification can be performed when network access is available.
