+
+### Using Web3.js
+
+```javascript
+const Web3 = require('web3');
+const web3 = new Web3('https://rpc-core.d-bis.org');
+
+// Oracle Proxy ABI (simplified)
+const oracleABI = [
+  {
+    "inputs": [],
+    "name": "latestRoundData",
+    "outputs": [
+      {"name": "roundId", "type": "uint80"},
+      {"name": "answer", "type": "int256"},
+      {"name": "startedAt", "type": "uint256"},
+      {"name": "updatedAt", "type": "uint256"},
+      {"name": "answeredInRound", "type": "uint80"}
+    ],
+    "stateMutability": "view",
+    "type": "function"
+  }
+];
+
+const oracleAddress = '0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6';
+const oracle = new web3.eth.Contract(oracleABI, oracleAddress);
+
+// Get latest price
+async function getPrice() {
+  const result = await oracle.methods.latestRoundData().call();
+  const price = result.answer / 1e8; // Convert from 8 decimals to USD
+  console.log(`ETH/USD Price: $${price}`);
+  return price;
+}
+
+getPrice();
+```
+
+### Using Ethers.js
+
+```javascript
+const { ethers } = require('ethers');
+
+const provider = new ethers.providers.JsonRpcProvider('https://rpc-core.d-bis.org');
+
+// Oracle Proxy ABI (simplified)
+const oracleABI = [
+  "function latestRoundData() external view returns (uint80 roundId, int256 answer, uint256 startedAt, uint256 updatedAt, uint80 answeredInRound)"
+];
+
+const oracleAddress = '0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6';
+const oracle = new ethers.Contract(oracleAddress, oracleABI, provider);
+
+// Get latest price
+async function getPrice() {
+  const result = await oracle.latestRoundData();
+  const price = result.answer.toNumber() / 1e8; // Convert from 8 decimals to USD
+  console.log(`ETH/USD Price: $${price}`);
+  return price;
+}
+
+getPrice();
+```
+
+---
+
+## 🔄 Oracle Publisher Service
+
+The Oracle Publisher service (VMID 3500) automatically updates the Oracle contract with price feeds.
+
+**Configuration**:
+- **Service**: Oracle Publisher
+- **VMID**: 3500
+- **Update Interval**: 60 seconds
+- **Price Source**: External API (e.g., CoinGecko, CoinMarketCap)
+
+---
+
+## ✅ Verification
+
+### Check Oracle is Updating
+
+```bash
+# Query latest round data
+cast call 0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 "latestRoundData()" --rpc-url https://rpc-core.d-bis.org
+```
+
+### Check Update Frequency
+
+The Oracle should update every 60 seconds (heartbeat). Monitor the `updatedAt` timestamp to verify.

+# MetaMask Token List Hosting Guide
+
+**Date**: $(date)  
+**Purpose**: Guide for hosting the MetaMask token list publicly
+
+---
+
+## 📋 Overview
+
+The MetaMask token list (`METAMASK_TOKEN_LIST.json`) needs to be hosted on a public URL for automatic token discovery in MetaMask.
+
+---
+
+## 🚀 Hosting Options
+
+### Option 1: GitHub Pages (Recommended)
+
+**Advantages**:
+- Free hosting
+- Easy to set up
+- Automatic HTTPS
+- Version control
+- CDN-backed
+
+**Steps**:
+
+1. **Prepare Token List**
+   ```bash
+   cd /home/intlc/projects/proxmox
+   bash scripts/host-token-list.sh github
+   ```
+   This creates `token-list.json` in the project root.
+
+2. **Create GitHub Repository** (if not exists)
+   - Create a new public repository
+   - Or use existing repository
+
+3. **Add Token List to Repository**
+   ```bash
+   git add token-list.json
+   git commit -m "Add MetaMask token list for ChainID 138"
+   git push
+   ```
+
+4. **Enable GitHub Pages**
+   - Go to repository Settings → Pages
+   - Select branch (usually `main` or `master`)
+   - Select folder: `/ (root)`
+   - Click Save
+
+5. **Access Token List**
+   - URL format: `https://<username>.github.io/<repo>/token-list.json`
+   - Example: `https://yourusername.github.io/token-list/token-list.json`
+
+6. **Add to MetaMask**
+   - MetaMask → Settings → Security & Privacy → Token Lists
+   - Click "Add custom token list"
+   - Enter your GitHub Pages URL
+   - Click "Add"
+
+---
+
+### Option 2: IPFS (Decentralized)
+
+**Advantages**:
+- Decentralized hosting
+- Permanent URLs
+- No single point of failure
+- Censorship-resistant
+
+**Steps**:
+
+1. **Install IPFS** (if not installed)
+   ```bash
+   # Follow: https://docs.ipfs.io/install/
+   ```
+
+2. **Start IPFS Node**
+   ```bash
+   ipfs daemon
+   ```
+
+3. **Add Token List to IPFS**
+   ```bash
+   cd /home/intlc/projects/proxmox
+   ipfs add docs/METAMASK_TOKEN_LIST.json
+   ```
+
+4. **Pin the File** (to keep it available)
+   ```bash
+   ipfs pin add <hash>
+   ```
+
+5. **Access Token List**
+   - IPFS Gateway: `https://ipfs.io/ipfs/<hash>`
+   - Pinata Gateway: `https://gateway.pinata.cloud/ipfs/<hash>`
+   - Cloudflare Gateway: `https://cloudflare-ipfs.com/ipfs/<hash>`
+
+6. **Add to MetaMask**
+   - Use any of the gateway URLs above
+   - Add to MetaMask token lists
+
+**Note**: IPFS hashes are permanent. If you update the token list, you'll get a new hash.
+
+---
+
+### Option 3: Custom Domain/Server
+
+**Advantages**:
+- Full control
+- Branded URL
+- Custom CDN
+- Professional appearance
+
+**Steps**:
+
+1. **Copy Token List to Server**
+   ```bash
+   scp docs/METAMASK_TOKEN_LIST.json user@server:/var/www/html/token-list.json
+   ```
+
+2. **Configure Web Server** (nginx example)
+   ```nginx
+   location /token-list.json {
+       add_header Access-Control-Allow-Origin *;
+       add_header Access-Control-Allow-Methods "GET, OPTIONS";
+       add_header Content-Type application/json;
+       try_files $uri =404;
+   }
+   ```
+
+3. **Ensure HTTPS**
+   - Use Let's Encrypt or similar
+   - MetaMask requires HTTPS for token lists
+
+4. **Access Token List**
+   - URL: `https://your-domain.com/token-list.json`
+
+5. **Add to MetaMask**
+   - Use your custom domain URL
+
+---
+
+## ✅ Verification
+
+### Test Token List URL
+
+```bash
+# Test accessibility
+curl -I https://your-url.com/token-list.json
+
+# Should return:
+# HTTP/2 200
+# Content-Type: application/json
+# Access-Control-Allow-Origin: *
+```
+
+### Validate JSON
+
+```bash
+# Validate JSON structure
+curl https://your-url.com/token-list.json | jq .
+
+# Should return valid JSON without errors
+```
+
+### Test in MetaMask
+
+1. Add token list URL to MetaMask
+2. Verify tokens appear automatically
+3. Check token metadata (name, symbol, decimals)
+4. Verify logos load (if configured)
+
+---
+
+## 📝 Token List Updates
+
+### Updating the Token List
+
+1. **Update Local File**

+# MetaMask Troubleshooting Guide - ChainID 138
+
+**Date**: $(date)  
+**Network**: SMOM-DBIS-138 (ChainID 138)
+
+---
+
+## 🔍 Common Issues & Solutions
+
+### 1. Network Connection Issues
+
+#### Issue: "Network Error" or "Failed to Connect"
+
+**Symptoms**:
+- MetaMask shows "Network Error"
+- Can't fetch balance
+- Transactions fail immediately
+
+**Solutions**:
+
+1. **Verify RPC URL**
+   ```
+   Correct: https://rpc-core.d-bis.org
+   Incorrect: http://rpc-core.d-bis.org (missing 's')
+   ```
+
+2. **Check Chain ID**
+   - Must be exactly `138` (decimal)
+   - Not `0x8a` (that's hex, but MetaMask expects decimal in manual entry)
+   - Verify in network settings
+
+3. **Remove and Re-add Network**
+   - Settings → Networks → Remove "SMOM-DBIS-138"
+   - Add network again with correct settings
+   - See [Quick Start Guide](./METAMASK_QUICK_START_GUIDE.md)
+
+4. **Clear MetaMask Cache**
+   - Settings → Advanced → Reset Account (if needed)
+   - Or clear browser cache and reload MetaMask
+
+5. **Check RPC Endpoint Status**
+   ```bash
+   curl -X POST https://rpc-core.d-bis.org \
+     -H "Content-Type: application/json" \
+     -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
+   ```
+
+---
+
+### 2. Token Display Issues
+
+#### Issue: "6,000,000,000.0T WETH" Instead of "6 WETH"
+
+**Root Cause**: WETH9 contract's `decimals()` returns 0 instead of 18
+
+**Solution**:
+
+1. **Remove Token**
+   - Find WETH9 in token list
+   - Click token → "Hide token" or remove
+
+2. **Re-import with Correct Decimals**
+   - Import tokens → Custom token
+   - Address: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
+   - Symbol: `WETH`
+   - **Decimals: `18`** ⚠️ **Critical: Must be 18**
+
+3. **Verify Display**
+   - Should now show: "6 WETH" or "6.0 WETH"
+   - Not: "6,000,000,000.0T WETH"
+
+**See**: [WETH9 Display Fix Instructions](./METAMASK_WETH9_FIX_INSTRUCTIONS.md)
+
+---
+
+#### Issue: Token Not Showing Balance
+
+**Symptoms**:
+- Token imported but shows 0 balance
+- Token doesn't appear in list
+
+**Solutions**:
+
+1. **Check Token Address**
+   - WETH9: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
+   - WETH10: `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f`
+   - Verify address is correct (case-sensitive)
+
+2. **Verify You Have Tokens**
+   ```bash
+   cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
+     "balanceOf(address)" <YOUR_ADDRESS> \
+     --rpc-url https://rpc-core.d-bis.org
+   ```
+
+3. **Refresh Token List**
+   - Click "Import tokens" → Refresh
+   - Or remove and re-add token
+
+4. **Check Network**
+   - Ensure you're on ChainID 138
+   - Tokens are chain-specific
+
+---
+
+### 3. Transaction Issues
+
+#### Issue: Transaction Stuck or Pending Forever
+
+**Symptoms**:
+- Transaction shows "Pending" for extended time
+- No confirmation after hours
+
+**Solutions**:
+
+1. **Check Network Status**
+   - Verify RPC endpoint is responding
+   - Check block explorer for recent blocks
+
+2. **Check Gas Price**
+   - May need to increase gas price
+   - Network may be congested
+
+3. **Replace Transaction** (Same Nonce)
+   - Create new transaction with same nonce
+   - Higher gas price
+   - This cancels the old transaction
+
+4. **Reset Nonce** (Last Resort)
+   - Settings → Advanced → Reset Account
+   - ⚠️ This clears transaction history
+
+---
+
+#### Issue: "Insufficient Funds for Gas"
+
+**Symptoms**:
+- Transaction fails immediately
+- Error: "insufficient funds"
+
+**Solutions**:
+
+1. **Check ETH Balance**
+   - Need ETH for gas fees
+   - Gas costs vary (typically 0.001-0.01 ETH)
+
+2. **Reduce Gas Limit** (If too high)
+   - MetaMask may estimate too high
+   - Try manual gas limit
+
+3. **Get More ETH**
+   - Request from network administrators
+   - Bridge from another chain
+   - Use faucet (if available)
+
+---
+
+#### Issue: Transaction Reverted
+
+**Symptoms**:
+- Transaction confirmed but reverted
+- Error in transaction details
+
+**Solutions**:
+
+1. **Check Transaction Details**
+   - View on block explorer
+   - Look for revert reason
+
+2. **Common Revert Reasons**:
+   - Insufficient allowance (for token transfers)
+   - Contract logic error
+   - Invalid parameters
+   - Out of gas (rare, usually fails before)
+
+3. **Verify Contract State**
+   - Check if contract is paused
+   - Verify you have permissions
+   - Check contract requirements
+
+---
+
+### 4. Price Feed Issues
+
+#### Issue: Price Not Updating
+
+**Symptoms**:
+- Oracle price seems stale
+- Price doesn't change
+
+**Solutions**:
+
+1. **Check Oracle Contract**
+   ```bash
+   cast call 0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 \
+     "latestRoundData()" \
+     --rpc-url https://rpc-core.d-bis.org
+   ```
+
+2. **Verify `updatedAt` Timestamp**
+   - Should update every 60 seconds
+   - If > 5 minutes old, Oracle Publisher may be down
+
+3. **Check Oracle Publisher Service**
+   - Service should be running (VMID 3500)
+   - Check service logs for errors
+
+4. **Manual Price Query**
+   - Use Web3.js or Ethers.js to query directly
+   - See [Oracle Integration Guide](./METAMASK_ORACLE_INTEGRATION.md)
+
+---
+
+#### Issue: Price Returns Zero or Error
+
+**Symptoms**:
+- `latestRoundData()` returns 0
+- Contract call fails
+
+**Solutions**:
+
+1. **Verify Contract Address**
+   - Oracle Proxy: `0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6`
+   - Ensure correct address
+
+2. **Check Contract Deployment**
+   - Verify contract exists on ChainID 138
+   - Check block explorer
+
+3. **Verify Network**
+   - Must be on ChainID 138
+   - Price feeds are chain-specific
+
+---
+
+### 5. Network Switching Issues
+
+#### Issue: Can't Switch to ChainID 138

+2. **Programmatic Addition** (For dApps)
+   ```javascript
+   try {
+     await window.ethereum.request({
+       method: 'wallet_switchEthereumChain',
+       params: [{ chainId: '0x8a' }], // 138 in hex
+     });
+   } catch (switchError) {
+     // Network doesn't exist, add it
+     if (switchError.code === 4902) {
+       await window.ethereum.request({
+         method: 'wallet_addEthereumChain',
+         params: [networkConfig],
+       });
+     }
+   }
+   ```
+
+3. **Clear Network Cache**
+   - Remove network

+# MetaMask WETH9 Display Bug Analysis
+
+**Date**: $(date)  
+**Issue**: MetaMask displaying "6,000,000,000.0T WETH" instead of "6 WETH"  
+**Contract**: WETH9 (`0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`)  
+**Network**: Defi Oracle Meta Mainnet (ChainID 138)
+
+---
+
+## 🐛 The Problem
+
+MetaMask is incorrectly displaying the WETH9 balance as **"6,000,000,000.0T WETH"** when the actual balance is **6 WETH**.
+
+### What MetaMask Shows
+- **Wrapped Ether**: `6,000,000,000.0T WETH` ❌ (Incorrect)
+- **Ethereum**: `1.00B ETH` (Also suspicious - likely 1 billion ETH)
+- **WETH**: `0 WETH` ✅ (Correct)
+
+### Actual On-Chain Values
+- **WETH9 Total Supply**: 6 WETH ✅
+- **WETH9 Contract Balance**: 6 ETH ✅
+- **User Balance**: 6 WETH ✅
+
+---
+
+## 🔍 Root Cause Analysis
+
+### Likely Causes
+
+1. **Missing or Incorrect `decimals()` Function**
+   - WETH9 may not implement the standard ERC-20 `decimals()` function
+   - MetaMask expects `decimals()` to return `18` for WETH
+   - If it returns `0` or doesn't exist, MetaMask may default to wrong decimal handling
+
+2. **MetaMask Number Formatting Bug**
+   - MetaMask may be reading the raw wei value: `6,000,000,000,000,000,000`
+   - Without proper decimals, it might be formatting as: `6,000,000,000.0T`
+   - The "T" likely stands for "Trillion" in MetaMask's display format
+
+3. **Token Metadata Issue**
+   - WETH9 may not be in MetaMask's token list
+   - MetaMask may be using default/incorrect metadata
+   - Missing proper token configuration for ChainID 138
+
+---
+
+## ✅ Verification
+
+### On-Chain Verification
+```bash
+# Check total supply (should be 6 WETH)
+cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
+  "totalSupply()" \
+  --rpc-url http://192.168.11.250:8545 | \
+  xargs -I {} cast --to-unit {} ether
+# Output: 6 ✅
+
+# Check contract balance (should be 6 ETH)
+cast balance 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
+  --rpc-url http://192.168.11.250:8545 | \
+  xargs -I {} cast --to-unit {} ether
+# Output: 6 ✅
+
+# Check decimals function
+cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
+  "decimals()" \
+  --rpc-url http://192.168.11.250:8545
+# Output: 0x0 (likely the issue!)
+```
+
+### Actual Values
+- **Raw Wei**: `6,000,000,000,000,000,000` wei
+- **ETH Equivalent**: `6.0` ETH
+- **Display Should Be**: `6 WETH` or `6.0 WETH`
+
+---
+
+## 🔧 Solutions
+
+### Solution 1: Add WETH9 to MetaMask Token List (Recommended)
+
+Create a proper token list entry for WETH9:
+
+```json
+{
+  "chainId": 138,
+  "address": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",
+  "name": "Wrapped Ether",
+  "symbol": "WETH",
+  "decimals": 18,
+  "logoURI": "https://raw.githubusercontent.com/ethereum/ethereum.org/main/static/images/eth-diamond-black.png"
+}
+```
+
+**Steps**:
+1. Create a token list JSON file
+2. Host it on a public URL (GitHub, IPFS, etc.)
+3. Add to MetaMask: Settings → Security & Privacy → Token Lists
+4. Or import directly in MetaMask: Import Token → Custom Token
+
+### Solution 2: Manually Import Token in MetaMask
+
+1. Open MetaMask
+2. Go to "Import tokens"
+3. Enter:
+   - **Token Contract Address**: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
+   - **Token Symbol**: `WETH`
+   - **Decimals of Precision**: `18`
+4. Click "Add Custom Token"
+
+### Solution 3: Fix WETH9 Contract (If Possible)
+
+If WETH9 contract can be modified, ensure it implements:
+- Standard ERC-20 `decimals()` function returning `18`
+- Standard ERC-20 interface
+
+**Note**: Since WETH9 is pre-deployed in genesis, this may not be possible without redeploying.
+
+### Solution 4: Use a Different WETH Contract
+
+If WETH9 cannot be fixed, consider:
+- Using WETH10 (`0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f`) if it has proper decimals
+- Deploying a new WETH contract with proper ERC-20 implementation
+
+---
+
+## 📊 Impact Assessment
+
+### Current Impact
+- **Display Issue**: Users see incorrect balance (6 trillion vs 6)
+- **Functional Impact**: None - transactions work correctly
+- **User Confusion**: High - misleading display
+
+### Risk Level
+- **Low**: This is purely a display issue
+- **No Financial Risk**: Actual balances are correct on-chain
+- **UX Issue**: Users may be confused or concerned
+
+---
+
+## 🔍 Additional Observations
+
+### Other Display Issues in Screenshot
+
+1. **Ethereum Balance**: Shows "1.00B ETH"
+   - This is also suspicious
+   - Should verify actual ETH balance
+   - May be another display formatting issue
+
+2. **Network Name**: "Defi Oracle Meta Mainnet"
+   - This is ChainID 138
+   - Network configuration appears correct
+
+3. **WETH Token**: Shows "0 WETH" ✅
+   - This appears correct
+   - May be a different WETH contract address
+
+---
+
+## 📝 Recommendations
+
+1. **Immediate**: Add WETH9 to MetaMask token list with proper decimals (18)
+2. **Short-term**: Verify all token contracts have proper `decimals()` implementation
+3. **Long-term**: Create comprehensive token list for ChainID 138
+4. **Documentation**: Document all token addresses and their proper configurations
+
+---
+
+## ✅ Verification Checklist
+
+- [x] On-chain balance verified: 6 WETH ✅
+- [x] Contract balance verified: 6 ETH ✅
+- [ ] `decimals()` function checked: Returns 0x0 (likely issue)
+- [ ] Token list entry created
+- [ ] MetaMask token import tested
+- [ ] Display verified after fix

+# MetaMask WETH9 Display Fix Instructions
+
+**Date**: $(date)  
+**Issue**: MetaMask showing "6,000,000,000.0T WETH" instead of "6 WETH"  
+**Root Cause**: WETH9 contract's `decimals()` returns 0 instead of 18
+
+---
+
+## 🔍 Problem Confirmed
+
+**Root Cause**: The WETH9 contract at `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2` has a `decimals()` function that returns `0x0` instead of `18`.
+
+When MetaMask reads the token balance:
+- It gets: `6,000,000,000,000,000,000` wei (raw value)
+- It expects: `decimals = 18` to format correctly
+- It gets: `decimals = 0` (incorrect)
+- Result: Displays as `6,000,000,000.0T WETH` ❌
+
+**Actual Balance**: 6 WETH ✅
+
+---
+
+## ✅ Solution: Manual Token Import in MetaMask
+
+Since the contract's `decimals()` function is incorrect, you need to manually specify the correct decimals when importing the token.
+
+### Step-by-Step Instructions
+
+1. **Open MetaMask**
+   - Make sure you're connected to "Defi Oracle Meta Mainnet" (ChainID 138)
+
+2. **Go to Import Tokens**
+   - Click on the token list (where you see "Wrapped Ether")
+   - Scroll down and click "Import tokens"
+   - Or go to: Settings → Tokens → Import tokens
+
+3. **Enter Token Details**
+   - **Token Contract Address**: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
+   - **Token Symbol**: `WETH`
+   - **Decimals of Precision**: `18` ⚠️ **IMPORTANT: Set this to 18**
+   - Click "Add Custom Token"
+
+4. **Verify**
+   - The token should now display as "6 WETH" instead of "6,000,000,000.0T WETH"
+   - You may need to remove the old token entry first if it exists
+
+---
+
+## 🔄 Alternative: Use Token List
+
+If you have access to host a token list JSON file:
+
+1. **Use the Updated Token List**
+   - File: `docs/METAMASK_TOKEN_LIST.json`
+   - Now includes WETH9 with correct decimals (18)
+
+2. **Host the Token List**
+   - Upload to GitHub, IPFS, or any public URL
+   - Example: `https://your-domain.com/token-list.json`
+
+3. **Add to MetaMask**
+   - Settings → Security & Privacy → Token Lists
+   - Add custom token list URL
+   - Or import directly in dApp
+
+---
+
+## 📊 Verification
+
+After fixing, verify the display:
+
+1. **Check Balance Display**
+   - Should show: `6 WETH` or `6.0 WETH` ✅
+   - Should NOT show: `6,000,000,000.0T WETH` ❌
+
+2. **Verify On-Chain Balance** (Optional)
+   ```bash
+   cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
+     "balanceOf(address)" <YOUR_ADDRESS> \
+     --rpc-url http://192.168.11.250:8545 | \
+     xargs -I {} cast --to-unit {} ether
+   # Should output: 6
+   ```
+
+---
+
+## 🐛 Why This Happens
+
+### WETH9 Contract Issue
+
+The WETH9 contract is an older implementation that:
+- ✅ Implements ERC-20 `balanceOf()`, `transfer()`, etc.
+- ❌ Does NOT properly implement `decimals()` (returns 0)
+- ❌ May not implement other ERC-20 optional functions
+
+### MetaMask Behavior
+
+When MetaMask encounters a token with `decimals = 0`:
+1. It reads the raw balance: `6000000000000000000`
+2. Without proper decimals, it doesn't know to divide by 10¹⁸
+3. It formats the number incorrectly
+4. Result: `6,000,000,000.0T` (treating it as a very large number)
+
+---
+
+## ✅ Expected Result
+
+After applying the fix:
+- **Before**: `6,000,000,000.0T WETH` ❌
+- **After**: `6 WETH` or `6.0 WETH` ✅
+
+---
+
+## 📝 Notes
+
+- This is a **display issue only** - your actual balance is correct on-chain
+- Transactions will work correctly regardless of the display
+- The fix only affects how MetaMask displays the balance
+- Other wallets may have the same issue if they rely on `decimals()`

+# MetaMask Oracle Integration Guide
+
+**Date**: $(date)  
+**ChainID**: 138  
+**Oracle Address**: $ORACLE_PROXY
+
+---
+
+## 📋 Overview
+
+This guide explains how to integrate the deployed Oracle contract with MetaMask for ETH/USD price feeds.
+
+---
+
+## 🔗 Contract Information
+
+- **Oracle Proxy Address**: \`$ORACLE_PROXY\`
+- **ChainID**: 138
+- **RPC Endpoint**: \`$RPC_URL\`
+- **Price Feed**: ETH/USD
+- **Decimals**: 8
+- **Update Frequency**: 60 seconds (heartbeat)
+
+---
+
+## 📝 MetaMask Network Configuration
+
+### Method 1: Manual Configuration
+
+1. Open MetaMask
+2. Click network dropdown → "Add Network" → "Add a network manually"
+3. Enter the following:
+   - **Network Name**: SMOM-DBIS-138
+   - **RPC URL**: \`$RPC_URL\`
+   - **Chain ID**: 138
+   - **Currency Symbol**: ETH
+   - **Block Explorer**: https://explorer.d-bis.org (optional)
+
+### Method 2: Import Configuration
+
+Use the configuration file: \`docs/METAMASK_NETWORK_CONFIG.json\`
+
+---
+
+## 💰 Reading Price from Oracle
+
+### Using Web3.js
+
+\`\`\`javascript
+const Web3 = require('web3');
+const web3 = new Web3('$RPC_URL');
+
+// Oracle Proxy ABI (simplified)
+const oracleABI = [
+  {
+    "inputs": [],
+    "name": "latestRoundData",
+    "outputs": [
+      {"name": "roundId", "type": "uint80"},
+      {"name": "answer", "type": "int256"},
+      {"name": "startedAt", "type": "uint256"},
+      {"name": "updatedAt", "type": "uint256"},
+      {"name": "answeredInRound", "type": "uint80"}
+    ],
+    "stateMutability": "view",
+    "type": "function"
+  }
+];
+
+const oracleAddress = '$ORACLE_PROXY';
+const oracle = new web3.eth.Contract(oracleABI, oracleAddress);
+
+// Get latest price
+async function getPrice() {
+  const result = await oracle.methods.latestRoundData().call();
+  const price = result.answer / 1e8; // Convert from 8 decimals to USD
+  console.log(\`ETH/USD Price: $\${price}\`);
+  return price;
+}
+
+getPrice();
+\`\`\`
+
+### Using Ethers.js
+
+\`\`\`javascript
+const { ethers } = require('ethers');
+
+const provider = new ethers.providers.JsonRpcProvider('$RPC_URL');
+
+// Oracle Proxy ABI (simplified)
+const oracleABI = [
+  "function latestRoundData() external view returns (uint80 roundId, int256 answer, uint256 startedAt, uint256 updatedAt, uint80 answeredInRound)"
+];
+
+const oracleAddress = '$ORACLE_PROXY';
+const oracle = new ethers.Contract(oracleAddress, oracleABI, provider);
+
+// Get latest price
+async function getPrice() {
+  const result = await oracle.latestRoundData();
+  const price = result.answer.toNumber() / 1e8; // Convert from 8 decimals to USD
+  console.log(\`ETH/USD Price: $\${price}\`);
+  return price;
+}
+
+getPrice();
+\`\`\`
+
+---
+
+## 🔄 Oracle Publisher Service
+
+The Oracle Publisher service (VMID 3500) automatically updates the Oracle contract with price feeds.
+
+**Configuration**:
+- **Service**: Oracle Publisher
+- **VMID**: 3500
+- **Update Interval**: 60 seconds
+- **Price Source**: External API (e.g., CoinGecko, CoinMarketCap)
+
+---
+
+## ✅ Verification
+
+### Check Oracle is Updating
+
+\`\`\`bash
+# Query latest round data
+cast call $ORACLE_PROXY "latestRoundData()" --rpc-url $RPC_URL
+\`\`\`
+
+### Check Update Frequency
+
+The Oracle should update every 60 seconds (heartbeat). Monitor the \`updatedAt\` timestamp to verify.
