1. Executive Summary

This security assessment evaluates the cross-chain bridge architecture utilized by the EigenCloud protocol. The assessment focuses on identifying architectural vulnerabilities, trust assumptions, economic security models, and potential vectors for critical fund drainage or unauthorized cross-chain message execution.

Cross-chain bridges represent a primary attack vector in Decentralized Finance (DeFi) due to the complex interaction between off-chain relaying mechanisms, cryptographic proof verification, and smart contract execution across heterogeneous consensus environments (Ethereum L1 to L2/ALT-L1).

2. Identified Attack Vectors & Vulnerability Analysis

Vector A: Validator Set Collusion & Cryptographic Threshold Exploitation

• Mechanism: If the bridge relies on an off-chain multi-signature or proof-of-stake (PoS) relayer set (e.g., EigenLayer AVS-based attestations), a compromise or collusion of $>50\%$ or $>66\%$ of the validating stake allows malicious actors to sign arbitrary state transitions.
• Impact: High. Unauthorized minting of wrapped assets on target chains or fraudulent withdrawal of L1 escrowed collateral.
• Risk Level: **Critical
