Governance Attack Surface Review: Spark Liquidity Layer

Target Protocol: Spark Liquidity Layer (TVL: $2680.4M)

Technical Security & Audit Report

Target: Governance Attack Surface Review — Spark Liquidity Layer

Context: MakerDAO / Spark Ecosystem (Ethereum Mainnet & L2 Deployments)

Scope: Architecture & Governance Mechanism Threat Model

Status: Completed

---

1. Executive Summary

The Spark Liquidity Layer acts as a core infrastructure component for liquidity allocation and credit facility management within the MakerDAO/Spark ecosystem across Ethereum Layer 1 and L2 extensions. Given the high Total Value Locked (TVL), governance vectors represent the primary catastrophic threat category, where malicious parameter manipulation or administrative compromise could lead to bad debt generation, insolvency, or direct asset drainage.

This security review evaluates the potential attack vectors within the governance lifecycle, multi-sig execution paths, timelock constraints, cross-chain messaging relays, and risk parameter management.

2. Identified Attack Vectors

Vector 1: Flash Loan / Short-Term Voting Weight Accumulation

• Mechanism: If voting tokens or voting delegation models rely on instantaneous balance snapshots without lockup periods, attackers can borrow governance tokens via flash loans or flash mints to swing critical parameter
