Introduction

Vector Shield Labs is an independent blockchain research and protocol security team specializing in cross-chain execution protection. Our mission is to provide high-assurance security modules that safeguard bridges, messaging layers, and DeFi protocols from advanced exploits, including:

• Replay & re-encoding attacks
• Temporal message manipulation
• Design-level logic vulnerabilities

We operate at the infrastructure layer, ensuring deterministic and verifiable execution of cross-chain operations.

Our Solution

Aegis BridgeGuard — a modular security layer that integrates directly into cross-chain message execution workflows:

• Message canonicalization to prevent encoding-based replay variants
• Execution lineage tracking to prevent duplicated or out-of-order messages
• Delayed execution control to reduce front-running and time-based attack vectors
• Emergency execution halt upon detection of anomalous patterns

Integration is flexible:
