Oracle Update Authorization

Date: $(date)
Issue: Oracle contract requires transmitter authorization to update prices

---

🔍 Problem

The oracle aggregator contract (0x99b3511a2d315a497c8112c1fdd8d508d4b1e506) enforces authorization checks. Only accounts authorized as "transmitters" can call updateAnswer().

Error Message: Aggregator: only transmitter

---

✅ Solution

Option 1: Use Authorized Transmitter Account

The oracle contract has specific transmitter addresses that are authorized to update prices. You must use one of these accounts:

1. Identify Transmitter Addresses: Query the oracle contract to find authorized transmitters
2. Use Transmitter Private Key: Set DEPLOYER_PRIVATE_KEY to the transmitter account's private key
3. Run Update Script: Execute the update script with the transmitter account

Option 2: Use Oracle Publisher Service (Recommended)

The Oracle Publisher service (VMID 3500) is configured to handle automatic price updates:

1. Service Configuration: /opt/oracle-publisher/.env

   • Uses the correct aggregator address
   • Configured with authorized transmitter account
   • Automatically updates every 60 seconds

2. Start Service:

   ssh root@192.168.11.10
   pct exec 3500 -- systemctl start oracle-publisher
   pct exec 3500 -- systemctl status oracle-publisher
   

3. Verify Updates:

   # Check service logs
   pct exec 3500 -- journalctl -u oracle-publisher -f
   
   # Query oracle to verify price updates
   cast call 0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 \
     "latestRoundData()" \
     --rpc-url https://rpc-http-pub.d-bis.org
   

Option 3: Manual Update with Authorized Account

If you need to manually update the oracle:

1. Get Authorized Transmitter Address:

   # Query oracle contract for transmitter addresses
   cast call 0x99b3511a2d315a497c8112c1fdd8d508d4b1e506 \
     "transmitters(uint256)" \
     0 \
     --rpc-url https://rpc-http-pub.d-bis.org
   

2. Use Transmitter Account:

   export DEPLOYER_PRIVATE_KEY="0x..." # Transmitter account private key
   ./scripts/update-all-oracle-prices.sh

📋 Current Configuration

• Oracle Proxy: 0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 (for reading)
• Oracle Aggregator: 0x99b3511a2d315a497c8112c1fdd8d508d4b1e506 (for updates)
• Update Method: updateAnswer(uint256) on aggregator
• Authorization: Only transmitter accounts can update

---

🔧 Script Status

The update-all-oracle-prices.sh script is correctly configured but requires:

• ✅ Correct aggregator address (0x99b3511a2d315a497c8112c1fdd8d508d4b1e506)
• ✅ Correct method signature (updateAnswer(uint256))
• ❌ Authorized transmitter account private key

---

✅ Recommended Approach

Use the Oracle Publisher Service (VMID 3500) for automatic updates:

• Already configured with correct addresses
• Uses authorized transmitter account
• Automatically updates every 60 seconds
• Handles errors and retries
• Provides monitoring and logging

Manual updates should only be used for:

• Initial setup
• Emergency updates
• Testing/debugging
