Three-Layer Security Architecture
How CrimsonARB protects capital through independent, layered verification
Executive Summary
CrimsonARB employs a three-layer security architecture where each layer operates independently and must approve before any capital is deployed. This design ensures that no single point of failure can result in fund loss.
On April 1, 2026, $285 million was drained from Drift Protocol in 12 minutes. The attack exploited trust assumptions, not code vulnerabilities. CrimsonARB's architecture would have blocked all three attack vectors through independent verification layers.
3 Attack Vectors Detected - 3 Attack Vectors Blocked - $0 Lost
Architecture Overview
Every yield opportunity passes through three independent verification layers before capital is deployed. Each layer has veto power. If any layer returns a negative signal, the operation is blocked.
Sentry Brain AI
Purpose
The Sentry Brain is an AI reasoning engine that evaluates every yield opportunity before capital is committed. It analyzes market conditions, token fundamentals, price history, and liquidity depth to generate a confidence score.
Evaluation Criteria
- Funding Rate Analysis: 24h velocity, decay prediction, historical patterns
- Liquidity Assessment: Order book depth, bid-ask spread, slippage estimation
- Token Fundamentals: Holder distribution, volume patterns, organic activity
- Price History: Anomaly detection, wash trading signals, manufactured patterns
Decision Outputs
Drift Attack Case Study: Layer 1 Response
The attacker created CVT (a fake token) with manufactured price history and artificial volume. Sentry Brain's analysis:
ATTACK VECTOR BLOCKED: Fake CVT collateral at manufactured price
AgentSentry ATSP
Purpose
AgentSentry is a protocol-level circuit breaker that monitors governance health, multisig configurations, and timelock parameters. It operates independently of market conditions and triggers GUARD state on any protocol-level anomaly.
Monitored Events
- Governance Migration: Any change to security council or admin keys
- Timelock Modification: Reduction or removal of safety delays
- Multisig Threshold: Changes to required signature count
- Oracle Updates: Price feed modifications or additions
Drift Attack Case Study: Layer 2 Response
Before the exploit, attackers migrated the Drift Security Council to a 2/5 threshold and removed the 48-hour timelock. AgentSentry's response:
ATTACK VECTOR BLOCKED: Governance migration removed safety timelocks
Webacy DD.xyz
Purpose
Webacy DD.xyz is a third-party AI risk intelligence platform that screens counterparty wallets against on-chain risk signals. It provides independent verification outside of CrimsonARB's internal systems.
Risk Signals Analyzed
- Mixer Origins: Tornado Cash, privacy mixer funding patterns
- Wallet Age: Recently created wallets with suspicious funding
- Sanctions Lists: OFAC and other regulatory blacklists
- Protocol History: Past exploit involvement, rug pull associations
Drift Attack Case Study: Layer 3 Response
The attacker wallets originated from Tornado Cash, were 8 days old, and funded via a privacy mixer. Webacy DD.xyz analysis:
ATTACK VECTOR BLOCKED: Tornado Cash-origin attacker wallet
Combined Defense Summary
| Attack Vector | Layer | Response |
|---|---|---|
| Fake CVT token | Sentry Brain | SKIP |
| Governance migration | AgentSentry | GUARD |
| Tornado Cash wallet | Webacy DD.xyz | BLOCK |
Result: $285,000,000 PROTECTED
