CASE STUDY
Sentrii
An Adaptive AI Powered Asset Security and Threat Detection System that scans through approved transactions in real-time for patterns used by drainers, instantly alerting users to revoke risky approvals before exploitation. Features asset lockdown (currently in development) protecting assets even during wallet compromise or private key leaks—locked assets can be recovered with multi-factor authentication. The last line of defense designed to identify threats, learn, adapt, and protect user assets beyond traditional transaction simulations.

The Problem
Most security tools in wallets today heavily rely on transaction simulations. These are good, but they have critical blind spots:
❌ Simulation Failures
What happens when the simulation fails to identify a well-hidden threat? Drainer developers use obfuscation techniques that often bypass simulations.
🔑 Private Key Leaks
What happens when a private key leaks? Your assets will be gone before you even realize what happened. No simulation can help you then.
⏰ Too Late
Over 80% of victims only realize they've been hacked when it's too late. Losses from drainers are at an all-time high.
This is why we built Sentrii — an active last line of defense for the average user, going beyond simulations to provide adaptive, real-time protection.

How Sentrii Works
Real-Time Scanning
Sentrii scans through your approved transactions in real-time for patterns used by drainers. Each time you approve a transaction anywhere, Sentrii actively monitors for threats before they execute.
Instant Alerts
Instantly alerts users to revoke risky approvals before they get exploited. Sentrii guides you on the next steps to take, providing actionable protection recommendations.
Asset LockdownIn Development
Allows users to lockdown assets from being transferred without proper multi-factor authorization. Even in the event of wallet compromise, private key leak, or instant drain, locked assets remain protected and can be recovered.
Learns & Adapts
Sentrii is designed to continuously learn and adapt to identify emerging threats. The system evolves with drainer techniques, staying ahead of obfuscation methods that bypass traditional simulations.

Asset LockdownIn Development
The ultimate protection layer. Lock down your assets with multi-factor authentication, ensuring that even if your wallet is compromised or your private key leaks, your funds remain safe and recoverable.
Multi-Factor Protection
Require multiple authentication factors before any locked assets can be transferred, adding an impenetrable layer of security beyond your wallet's private key.
Compromise Recovery
Even if your wallet is compromised or your private key is leaked, locked assets remain protected and can be recovered through the secondary authentication system.
Time-Delayed Transfers
Set custom time delays for large transactions, giving you a window to cancel suspicious transfers before they execute.
Flexible Control
Choose which assets to lock, set custom security levels, and maintain full control over your protection preferences.

Multi-Layer Threat Detection
Layer 1: Rust Fast Path (5ms)
High-performance Rust core deployed on Render performs lightning-fast discriminator matching and bytecode analysis. Extracts 8-byte function signatures from raw instruction data to identify malicious patterns like claimCreatorRoyalties, unlimited approvals (u64::MAX), and SetAuthority attempts.
Discriminator Analysis
Extracts function signatures from raw instruction bytes
Bytecode Decoding
Parses instruction parameters, amounts, and authorities
Pattern Matching
Catches 80% of known threats in under 5ms
Layer 2: Behavioral Pattern Analysis (20ms)
Deep behavioral analysis examines transaction structure, token flow patterns, and cross-program invocations. Analyzes writable account counts, unknown program interactions, and structural anomalies to catch novel attacks that haven't been seen before.
Layer 3: Context Analysis (10ms)
Validates transactions against a whitelist of 50+ legitimate DeFi protocols (Jupiter, Raydium, Orca, Phoenix). Detects legitimate swap patterns, checks user initiation, and analyzes token flow direction to reduce false positives while maintaining high detection accuracy.
Layer 4: ML Threat Detection (50ms)
TensorFlow.js-powered machine learning models trained on thousands of malicious transactions. Extracts 32 features including instruction complexity, account relationships, and behavioral patterns. Uses Isolation Forest for anomaly detection with 97.3% accuracy.

System Impact
Sentrii represents a fundamental shift in Web3 security—from reactive to proactive protection. By analyzing threats before they execute and providing asset protection even after key compromise, we're making crypto interactions safe for everyone.
For Users
Silent background protection that requires no technical knowledge. Multi-layer threat detection catches attacks in 600ms-2s, providing real-time alerts. Lockdown system protects assets even if your private key is stolen.
For the Ecosystem
Building trust in Web3 by eliminating the fear of wallet drainer attacks. Advanced bytecode analysis and behavioral detection accelerate mass adoption by making crypto security accessible to everyone.
