Aave V2 is a mature but aging lending protocol. While it benefits from Aave's strong brand and governance infrastructure, its legacy status means declining liquidity and lower security priority. Users with remaining V2 positions should actively plan migration to V3 to access better risk parameters and deeper liquidity.
Top Risks
1
Aave V2 is a legacy deployment with active migration to V3/V4. Governance attention and security patches prioritize newer versions, leaving V2 with slower response times to emerging threats.
2
November 2023 security incident affected V2 markets across multiple chains, requiring emergency asset freezes. While no funds were lost, the vulnerability pattern demonstrates V2's aging codebase risk.
3
At $135M remaining TVL, V2 still holds substantial user funds in deprecated markets where interest rate models and risk parameters receive less frequent governance updates.
Risk Breakdown
Frequently Asked Questions
Is Aave V2 safe to use?
Aave V2 receives a B- risk grade (33/100) from Hindenrank, where lower scores indicate lower risk. Aave V2 is a mature but aging lending protocol. While it benefits from Aave's strong brand and governance infrastructure, its legacy status means declining liquidity and lower security priority. Users with remaining V2 positions should actively plan migration to V3 to access better risk parameters and deeper liquidity. Aave V2 is the legacy version of the world's largest lending protocol. While Aave V3 has taken over as the primary deployment with advanced features like efficiency mode and isolation mode, V2 still holds roughly $135 million in deposits across Ethereum, Polygon, and Avalanche. V2 uses the same core overcollateralized lending model but lacks modern risk management improvements. Governance and security attention increasingly focuses on V3 and the upcoming V4, making V2 a lower-priority legacy system.
What are the main risks of using Aave V2?
The key risks identified for Aave V2 are: (1) Legacy codebase receives less governance attention and slower security updates than V3/V4 (2) November 2023 security incident required emergency freezes across V2 markets on multiple chains (3) Declining liquidity as users migrate to V3 may cause interest rate spikes and withdrawal difficulties (4) Shared safety module with V3 means V2 shortfall events impact the broader Aave ecosystem
