## 📝 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

## 💰 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.
