Flash Loan Attack Vector Analysis: Veda
Flash Loan Attack Vector Analysis: Veda Target Protocol : Veda (TVL: $1819.4M) Veda – Flash‑Loan Attack Vector Analysis TVL: ≈ $1.819 B (Ethereum + L2) Prepared by: Senior DeFi Security Researcher – [Your Name] Date: 2026‑10‑29 1. Executive Summary Veda is a high‑value, multi‑chain lending/borrowing platform that aggregates liquidity across Ethereum L1 and several L2 roll‑ups. Its core…
Veda is a lending/borrowing protocol that pools liquidity across Ethereum and multiple Layer 2 networks. It relies on on-chain price feeds, liquidation rules, and flash loan compatibility for its operations. This analysis focuses on the most dangerous flash loan attack vectors for Veda.
The analysis identifies five main attack vectors:
1. Oracle price manipulation via flash loan-driven token swaps, which is high likelihood and could cause up to 30% TVL loss.
2. Flash loan-enabled liquidation sandwich attacks, which are medium-high likelihood and could steal up to 5% TVL.
3. Re‑entrancy through flash loan-compatible vault callbacks, with a medium likelihood and potential for up to 10% TVL loss.
4. Governance parameter hijacking via flash loan-sponsored voting power acquisition, which has low-medium likelihood and could result in 20% TVL damage.
5. Cross-chain bridge flash loan attacks are low likelihood and could lead to up to 5% TVL loss.
The most critical weakness is the use of a single source, low-liquidity oracle price feed. To mitigate these risks, Veda should implement multi-source oracles with longer delays and price deviation caps. Liquidation protection windows and dynamic reward scaling can also help reduce sandwich attack impact. Re‑entrancy vulnerabilities should be eliminated using proper security patterns, and governance proposals should include stricter voting requirements to prevent manipulation.
