Contract Deployment Flow

Multi-Network Deployment

Network Configuration Matrix

Network	Gas Costs	Block Time	Recommended Update Frequency
Ethereum Mainnet	High (~$10-50)	12s	5-15 minutes
Polygon	Low (~$0.01-0.10)	2s	1-2 minutes
Arbitrum	Medium (~$0.50-2)	~1s	30-60 seconds
Optimism	Medium (~$0.50-2)	2s	30-60 seconds
BSC	Low (~$0.10-0.50)	3s	1-2 minutes

Cross-chain Deployment Strategy

// Network-specific configuration
struct NetworkConfig {
    uint256 updateFrequency;     // Seconds between updates
    uint256 maxStaleness;        // Maximum acceptable data age
    uint256 gasOptimization;     // Batch size for gas efficiency
    address relayerNode;         // Network-specific relayer

Infrastructure Requirements

Relayer Node Specifications

Minimum Requirements:

• CPU: 2 cores, 2.5GHz+
• RAM: 4GB minimum, 8GB recommended
• Storage: 100GB SSD
• Network: Stable internet, low latency to RPC endpoints
• Uptime: 99.5%+ availability required

Recommended Production Setup:

• CPU: 4+ cores, 3.0GHz+
• RAM: 16GB+
• Storage: 500GB NVMe SSD
• Network: Redundant connections, multiple RPC providers
• Uptime: 99.9%+ with failover capabilities

Price Data Sources

Operational Monitoring

Critical Metrics Dashboard

Price Update Frequency:     Target vs Actual intervals
Data Source Availability:   % uptime per source
Validation Success Rate:    % successful submissions  
Gas Cost Tracking:         USD cost per update
Network Congestion:         Current gas prices
Asset Coverage:             Number of supported assets
Consumer Health:           Active integrations status

Alert Thresholds

Critical Alerts:
  - Price updates stopped > 5 minutes
  - Relayer node offline > 2 minutes
  - Validation failure rate > 5%
  - Price deviation > 10% from external sources

Warning Alerts:
  - Update frequency below target
  - High gas cost environment
  - Single data source failure
  - Consumer integration errors

Security Operations

Key Management

Incident Response Procedures

1. Price Feed Anomaly Detection

   • Automated circuit breakers
   • Manual override capabilities
   • Stakeholder notification protocols

2. Relayer Compromise Response

   • Immediate relayer address rotation
   • Historical data validation
   • System integrity verification

3. Network Congestion Handling

   • Dynamic gas price adjustment
   • Priority transaction batching
   • Alternative network failover

Upgrade & Maintenance

Contract Upgradeability

The IFA Oracle follows an immutable contract design with configurable components:

// Non-upgradeable core logic (immutable)
contract IfaPriceFeed { ... }

// Configurable validation logic  
contract IfaPriceFeedVerifier { 
    function setRelayerNode(address newRelayer) external onlyOwner;
}

// Operational parameters
contract OracleConfig {
    uint256 public maxStaleness;
    uint256 public updateFrequency;
    mapping(bytes32 => bool) public supportedAssets;
}

Maintenance Windows

• Regular Maintenance: Weekly during low-usage periods
• Emergency Maintenance: Immediate response capability
• Planned Upgrades: 48-hour advance notice to integrators
• Network Upgrades: Coordination with blockchain network upgrades

Backup & Recovery

Data Backup Strategy:
  - Real-time price data archival
  - Contract state snapshots
  - Configuration backups
  - Event log preservation

Recovery Procedures:
  - Relayer node failover (< 30 seconds)
  - Data source switching (< 60 seconds)  
  - Network migration (planned maintenance)
  - Emergency pause capability
