SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Monitor blockchain addresses and contracts for notable activity and automatically raise alerts when thresholds or unusual patterns are detected.

Core Features & Use Cases

  • Real-time watch and alerting for wallet and contract activity across major chains.
  • Stateful memory with per-watch analytics including last_block, last_run, and alert history.
  • Tag-based classification (WHALE-TRANSFER, CEX-OUT, DEX-SWAP, etc.) and configurable thresholds via memory/on-chain-watches.yml.
  • Auditing and persistent logging through memory/logs and memory/on-chain-state.json.

Quick Start

Configure memory/on-chain-watches.yml with your watches and run the monitor to begin receiving alerts.

FAQPage Schema
How do I monitor blockchain wallet and contract activity for alerts?▼

To monitor blockchain wallet and contract activity for alerts, configure the memory/on-chain-watches.yml file with target addresses and thresholds, then run the monitor to receive automated alerts.

What are whale transfers and CEX-out alerts in on-chain monitoring?▼

Whale transfers and CEX-out alerts are tag-based classifications used in on-chain monitoring to identify large cryptocurrency transfers or movements toward centralized exchanges, aiding rapid alert triage.

Can I track on-chain transfers across multiple blockchain networks?▼

Yes, you can track on-chain transfers across multiple blockchain networks. The monitor operates across major chains, maintaining per-watch state and alert history for configured wallets and contracts.

How does stateful memory work for blockchain alert monitoring?▼

Stateful memory for blockchain alert monitoring tracks last_block and last_run data per watch, persisting state in memory/on-chain-state.json to ensure continuous, gapless alerting and historical auditing.

How do I configure thresholds for DEX swaps and notable on-chain events?▼

You configure thresholds for DEX swaps and notable on-chain events by defining rules in the memory/on-chain-watches.yml file, allowing the monitor to raise alerts when unusual patterns are detected.
