# 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**:
|
|
```bash
|
|
ssh root@192.168.11.10
|
|
pct exec 3500 -- systemctl start oracle-publisher
|
|
pct exec 3500 -- systemctl status oracle-publisher
|
|
```
|
|
|
|
3. **Verify Updates**:
|
|
```bash
|
|
# 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**:
|
|
```bash
|
|
# 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**:
|
|
```bash
|
|
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
