Add anomaly detection for unusually large transaction volumes

[Abdulazeem-code]

Description

Sudden spikes in transaction volume could indicate an exploit or bot activity.

Proposed Solution

Implement a cron job or sliding window logic that flags accounts exceeding 1000% of their daily average volume and triggers an alert.

Acceptance Criteria

• Heuristic logic implemented
• Alerts dispatched to Slack/Email when anomaly detected
• Optional auto-pause mechanism for flagged accounts

Suggested Implementation Areas

src/scripts/anomalyMonitor.js, src/server.js

Impact

Provides early warning systems for fraud and potential smart contract exploits.
