Prevention and monitoring

End-to-end monitoring includes:

• Per-update gas monitoring: catch abnormal single-update gas spikes early to control cost or spot logic issues
• Price update frequency: ensure no feed stays stale too long
• On-chain vs third-party price divergence: continuous comparison
• Volatility anomaly: historical volatility stats with alerts when realized vol diverges sharply from normal
• API availability: price read paths respond and return valid data
• Source count: avoid reliance on a single venue; ensure quotes draw from multiple liquid markets
• Stablecoin depeg: detect abnormal moves vs the peg (e.g. USD)
• Contract permission changes (Admin / Owner / Reporter): detect adds/removes/changes to critical roles
• Contract revert events: log reverts in real time for faster root-cause and risk review
• Node / RPC health: catch stalled block height, lag, or queue backlog
• Wallet balances: ensure operational wallets hold enough funds so critical actions do not fail for lack of gas
