Show HN: XeraSentry – Real-time Ethereum security monitoring in Python

I built XeraSentry over 3 months - a Python tool that monitors Ethereum for security threats in real-time.

What it does: - Detects whale movements (50+ ETH transfers) - High-value transfer alerts (configurable threshold) - Tracks sanctioned addresses (OFAC compliance) - Monitors specific wallets you care about - Address poisoning detection - MEV bot detection

Tech stack: Python + Web3.py, SQLite database, Google Sheets integration, RPC failover system with 5 backup endpoints, transaction deduplication.

Already detected $70K+ in test runs with 10 modular detection rules.

Currently in private beta (limited to 50 testers) before open source launch on January 5, 2025.

Built this solo because I was tired of missing whale movements and wanted a tool that runs locally (no API keys) with full visibility.

Would love feedback from the HN community - especially on the technical architecture or what features to prioritize before launch!
