# Oracle Update Script Fix

**Last Updated:** 2026-01-31  
**Document Version:** 1.0  
**Status:** Active Documentation

**Date:** 2026-01-27  
**Issue:** Script was using inaccessible RPC endpoint  
**Status:** ✅ Fixed

---

## 🔧 Problem

The `update-oracle-price.sh` script was failing with:
```
[ERROR] RPC is not accessible at http://192.168.11.250:8545
```

**Root Cause:**
- Script was using `RPC_URL` from `.env` which pointed to `192.168.11.250:8545` (internal-only, not accessible)
- Should prioritize `RPC_URL_138` which points to `192.168.11.211:8545` (accessible)

---

## ✅ Solution

### Changes Made

1. **RPC URL Priority Fix:**
   - Changed priority: `RPC_URL_138` > `RPC_URL` > default
   - Added automatic fallback to working RPC endpoints

2. **Automatic RPC Fallback:**
   - Script now tests RPC connectivity
   - Falls back to alternative RPCs if primary fails
   - Tries: `192.168.11.211:8545` → `https://rpc-http-pub.d-bis.org`

3. **Better Error Handling:**
   - Added timeout to transaction sending (90 seconds)
   - Improved transaction hash extraction
   - Better error messages

### Updated Code

```bash
# RPC URL priority: command arg > RPC_URL_138 > RPC_URL > working defaults
DEFAULT_RPC="http://192.168.11.211:8545"
RPC_URL="${1:-${RPC_URL_138:-${RPC_URL:-$DEFAULT_RPC}}}"

# Test RPC and fallback if needed
if ! curl -s -X POST -H "Content-Type: application/json" \
    --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
    --max-time 3 "$RPC_URL" > /dev/null 2>&1; then
    log_warn "Primary RPC not accessible, trying alternatives..."
    # Try alternative RPCs
    for ALT_RPC in "http://192.168.11.211:8545" "https://rpc-http-pub.d-bis.org"; do
        if curl -s -X POST -H "Content-Type: application/json" \
            --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
            --max-time 3 "$ALT_RPC" > /dev/null 2>&1; then
            log_info "Using alternative RPC: $ALT_RPC"
            RPC_URL="$ALT_RPC"
            break
        fi
    done
fi
```

## 🚀 Usage

### Basic Usage

```bash
cd /home/intlc/projects/proxmox/smom-dbis-138
./scripts/update-oracle-price.sh
```

The script will:
1. Load `.env` file
2. Use `RPC_URL_138` if available (preferred)
3. Fall back to `RPC_URL` if needed
4. Automatically try alternative RPCs if primary fails
5. Update oracle with current ETH/USD price from CoinGecko

### With Explicit RPC

```bash
./scripts/update-oracle-price.sh https://rpc-http-pub.d-bis.org
```

### With Explicit Parameters

```bash
./scripts/update-oracle-price.sh [rpc-url] [oracle-address] [private-key]
```

---

## ✅ Verification

After running the script, verify the oracle was updated:

```bash
RPC_URL="http://192.168.11.211:8545"
ORACLE="0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6"

# Get latest price
cast call "$ORACLE" "latestRoundData()" --rpc-url "$RPC_URL"

# The answer field (in 8 decimals) should be non-zero
```

---

## 📊 Current Status

- ✅ Script fixed and working
- ✅ Uses correct RPC endpoint
- ✅ Automatic fallback to working RPCs
- ✅ Better error handling
- ⏳ Oracle currently returns zero (needs price update)
