• Persistent Event Storage — SQLite/PostgreSQL backend for event history beyond in-memory buffer
• Custom Event Signatures — User-defined event ABIs for monitoring non-standard contracts
• Webhook Alert Channel — Generic outbound webhook for custom integrations
• Rate Limit Management — Per-provider RPC quota tracking and automatic failover
• Docker Container — Official Docker image for one-command deployment
• CounterScarp.io Integration — Direct integration with CounterScarp scanning results for pre+post deployment coverage
