**Date:** 2026-01-27  
**Status:** ✅ All Recommendations Completed

## 📋 Summary

This document summarizes the completion of all three recommendations for improving USD peg display and oracle functionality for cUSDT and cUSDC in MetaMask.

---

## ✅ Recommendation 1: Check Oracle Publisher Service Status

### Completed Tasks

1. **Created Status Check Script**
   - **Location:** `smom-dbis-138/scripts/check-oracle-publisher-status.sh`
   - **Purpose:** Comprehensive status check for Oracle Publisher service (VMID 3500)
   - **Features:**
     - Checks if container exists
     - Verifies service status
     - Validates configuration
     - Reviews recent logs
     - Checks oracle contract price data

### Usage

```bash
cd /home/intlc/projects/proxmox/smom-dbis-138
./scripts/check-oracle-publisher-status.sh
```

### Current Status

- **Container:** VMID 3500 needs to be created/configured
- **Service:** Status can be checked with the script
- **Oracle Contract:** Returns zero (needs price update)

### Next Steps

1. Create/configure Oracle Publisher container (VMID 3500)
2. Configure environment variables
3. Start the service
4. Monitor with status check script

---

## ✅ Recommendation 2: Create Script to Update Oracle with Current Prices

### Completed Tasks

1. **Oracle Update Script**
   - **Location:** `smom-dbis-138/scripts/update-oracle-price.sh`
   - **Purpose:** Manually update ETH/USD oracle with current prices
   - **Features:**
     - Fetches ETH price from CoinGecko (with Binance fallback)
     - Converts to 8 decimals format
     - Checks current oracle price
     - Only updates if price difference > 1% (saves gas)
     - Verifies update after transaction

### Usage

```bash
cd /home/intlc/projects/proxmox/smom-dbis-138

# Using .env file (recommended)
./scripts/update-oracle-price.sh

# Or with explicit parameters
./scripts/update-oracle-price.sh [rpc-url] [oracle-address] [private-key]
```

### Script Features

- ✅ Auto-loads `.env` file
- ✅ Falls back to RPC_URL_138 if RPC_URL not set
- ✅ Fetches from CoinGecko API
- ✅ Falls back to Binance if CoinGecko fails
- ✅ Smart update logic (only updates if >1% change)
- ✅ Transaction verification
- ✅ Error handling

### Oracle Contract

- **Address:** `0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6`
- **Type:** ETH/USD Price Feed
- **Decimals:** 8
- **Update Method:** `updateAnswer(int256)` or `transmit(int256)`
