Lesson 36: Final Exercise (Building a Full Security Monitoring Stack from Scratch)
After 35 meditations on blockchain monitoring, detection engineering, and Forta mastery… it’s time to step fully into the role of Guardian of the Chain.
This final lesson is your rite of passage, where you put together a full-stack security monitoring system using everything you have learned.
By the end of this exercise, you will have:
Built a live monitoring bot
Configured alert routing
Integrated with dashboards or SIEMs
Simulated an attack and received the alert
Completing this exercise is real evidence of your skills in action.
Why this is important in Blockchain Monitoring
In the real world, security engineers don’t just detect threats, they build infrastructure that scales across protocols, teams, and chains.
As a Forta Administrator or monitoring bot developer, you’re now expected to:
Deploy bots that stay online 24/7
Send alerts to devs, ops, and SOC teams
Document everything for audit and compliance
Extend the system as threats evolve
This lesson prepares you for that.
Project Blueprint
Here’s what your full monitoring stack will include:
Step-by-Step Guide
1. Clone the Forta Bot Template
npx forta-agent init my-final-bot
cd my-final-bot2. Choose a Detection Logic
Example: flag any swap > $500K on Uniswap.
Use logic similar to:
if (tx.value > 500_000 && tx.to === UNISWAP_ROUTER) {
emitAlert("High-Value Swap Detected")
}3. Add Tests
Use handleTransaction.test.js to simulate cases and confirm alerts trigger only on correct input.
4. Deploy to Forta

5. Set Up Alert Routing
Use:
Webhook --> Discord via Forta Webhook Alerts
Or forward to:
Splunk
Telegram bot
Custom Web server
6. Create a Grafana Panel
Use Prometheus or custom JSON logging to show:
Volume of alerts over time
Per bot ID stats
Most frequent alert types
7. Write Your Bot README
Document:
Threat detected
Logic explanation
Alert IDs used
Example JSON alert
8. Simulate an Attack
Send a transaction on testnet that matches your condition.
If everything works, you’ll see:
Agent triggers
Alert emits
Message hits Discord
Dashboard updates
Additional Challenge
Extend this bot to monitor:
Multiple chains (Polygon, Arbitrum)
Multiple contracts (DAOs, vaults)
False positive suppression
Example project
Key Concepts Recap
A full monitoring stack includes agent logic, routing, and visualization
Forta supports bots that scale across chains and contracts
This final exercise simulates real-world security workflows
You are now equipped to defend live blockchain ecosystems
You have reached the end of the Forta Monk Path.
May your bots be lean, your alerts accurate, and your chains safe 🙏.
Until the next meditation,
