Flash Loan Attack Vector Analysis: SparkLend

Target Protocol: SparkLend (TVL: $5071.0M)

Executive Summary

SparkLend is a decentralized liquidity protocol built as a fork of Aave v3, operating on Ethereum and various Layer 2 ecosystems. Due to its architecture, SparkLend utilizes uncollateralized Flash Loans to facilitate arbitrage, collateral swapping, and position liquidations.

While Flash Loans are a standard feature of modern lending pools, they serve as capital multipliers in attack scenarios. A threat model analysis of SparkLend indicates that while core smart contracts inherit Aave v3's battle-tested access controls, risks primarily manifest at the integration boundaries—specifically regarding oracle pricing models, market liquidity depth, and isolation parameters for newly listed assets.
