Webhook → Slack notifier

Build a production Telegram alert bot that streams real-time liquidation events from Hyperliquid's BTC-PERP order book. The bot must deliver sub-second alerts via webhook to a designated Telegram channel and maintain 24-hour uptime.

This is a focused, well-scoped task. We expect a working implementation, not a prototype. Reference the Hyperliquid ws docs and grammY Telegram framework.

Requirements

• Subscribe to liquidations.BTC-PERP channel
• Filter events ≥ $50k in notional size
• Telegram bot deployed at @hl_liquidations
• p95 latency < 800ms · uptime ≥ 99.0%
• systemd unit · auto-restart on crash

Deliverables

• GitHub repository (MIT or Apache-2.0)
• README with setup, deploy, and runbook sections
• Live Telegram channel URL with at least 24h of historical alerts
• Test transcript showing latency + uptime metrics

Acceptance criteria

• Validator quorum (5/5) signs the completion proof
• 24h uptime check passes from independent observer
• No PII or private keys committed to repository
