Aave V3 does not need to be migrated to V4 right now. The official team has clearly stated that migration will not be forced. V3 will continue to operate normally for the foreseeable future. V4 is using a "controlled launch" strategy, with deposit caps in the early phase, while V3 currently holds tens of billions of dollars in liquidity. What is worth your time now is judging whether V4's architectural changes are worth actively moving your positions over for, and what risks you will face in V4 that did not exist in the V3 era.

Official Stance: No Deadline, V3 Will Not Be Shut Down
Aave Labs members specifically clarified the V3 to V4 transition timeline in February 2026, emphasizing that "V3 will continue to operate normally for the foreseeable future and will not be immediately replaced even after V4 launches." Discussions on the governance forum confirmed the same point: the V3 market will keep running, depositors can choose when to migrate, and there is no mandatory requirement.
Aave is also developing a tool that lets you move liquidity from V3 to V4 without first unwinding your positions, but this feature is not expected to be available on day one of V4's launch. So you do not need to rush into any action just because "V4 is already live."
V4's launch method is a "controlled launch": conservative caps on deposits will be set initially, then gradually expanded. As of August 2026, V4's TVL is between $217 million and $225 million, while V3 still holds about $19.4 billion in TVL during the same period. The two are not yet on the same scale.
What V4 Actually Changed and Whether It Is Worth Migrating For
V4's core change is restructuring V3's "one isolated pool per chain" into a two-layer structure of a "Liquidity Hub + Borrow Spokes."
In V3, when you deposit assets into a market, those assets can only be borrowed within that market. Liquidity is isolated between different markets. V4 concentrates liquidity in the Hub, and each Spoke acts as an independent lending market that draws liquidity from the Hub. Each Spoke can have its own collateral list, risk parameters, and interest rate curves.
The practical change from this design: the friction for launching long-tail assets and new markets is lower. In the V3 era, a new market needed to attract deposits from zero. In V4, a Spoke can directly obtain liquidity from the shared Hub without needing to build its own pool from scratch. If you are watching new lending scenarios emerging in the Aave ecosystem, V4 is indeed better suited to support them than V3.
But for your existing positions, migrating to V4 will not automatically give you higher yields or lower borrowing costs. V4's interest rate model is still based on supply and demand, just shifting from a single market to an average utilization rate across Spokes. For simple deposits and borrows of major assets like ETH and USDC, the experience difference between V3 and V4 will not be very large.
My judgment is this: if you are only depositing USDC or ETH on Aave to earn interest, or borrowing stablecoins for simple leverage, there is currently no good reason to actively migrate to V4. Migration requires you to learn a new interface, re-approve transactions, and possibly face initial capacity limits, while V3's functionality and liquidity are still operating normally.
If your strategy involves new scenarios that only V4 supports—such as RWA asset lending, more granular risk pricing, or a specific Spoke market that is only deployed on V4—then migration has a clear purpose. Do not migrate just because "the version number has been updated."
Risks You Need to Seriously Consider with V4 Right Now
V4 is not a simple upgrade of V3. Its smart contracts, architecture, and liquidation logic are all brand new, which means the security track record that V3 has accumulated over the past few years cannot be directly applied to V4.
Independent risk assessment firm Hindenrank gave Aave V4 a rating of C+ (42/100) in May 2026, placing it in the "moderately low but on the higher side" tier, ranking 71st out of 99 lending protocols. The core risks highlighted in the report include:
Hub single point of failure. V4 concentrates all liquidity in one Hub contract, and all Spokes share this Hub. If the Hub contract has a serious vulnerability that gets exploited, liquidity across all connected markets would be affected at the same time. V3's isolated pool design does not have this risk. The report specifically noted that V4's Hub had not been attacked as of the assessment date, but this architecture has not yet been proven at scale with large amounts of capital.
Inherited CAPO oracle issues. V4 uses Aave's CAPO (Chainlink Adaptive Price Oracle) layer. This oracle layer experienced a failure on V3 on March 10, 2026, causing roughly $27 million in incorrect liquidations across 34 accounts. The report noted that V4's oracle stack runs the same logic, and there is no record showing this issue has been fixed.
Changes at the governance level. The Aave Chan Initiative (ACI, which previously handled 61% of DAO governance operations) and BGD Labs both left in early 2026. V4's launch phase happens to be the period when the new Hub/Spoke architecture needs frequent risk parameter adjustments, and the weakening of governance capacity means parameter decisions are increasingly concentrated in the hands of Aave Labs. Decentralized oversight has actually decreased during V4's critical growth period.
These risks are not a prediction that "V4 will definitely fail." They mean that V4 is a new protocol that has been running for less than a year, and its security record, oracle stability, and governance structure are still taking shape. If you are depositing a large amount of capital on V4, or if your positions involve complex strategies that only V4 has (such as multi-step operations with Position Manager), you need to evaluate these risks more carefully than you would on V3.
If You Decide to Migrate, What Is the Path
The migration tool Aave's team is developing aims to let users move positions from V3 to V4 without first repaying borrows and unwinding positions. The specific interaction method of this tool cannot currently be confirmed from public sources, and the official team has said it will not be available on day one of V4's launch.
Until the migration tool is available, if you want to move from V3 to V4, you need to do it manually: repay your borrows on V3, withdraw your deposits, and then re-deposit or borrow on V4. This process itself is not complicated, but there are two things to pay attention to:
If there is too much time between repaying your borrows and withdrawing your deposits, your position could get liquidated due to market volatility. Make sure you have enough collateral buffer, or do it in batches.
V4's Spoke markets may have deposit caps. V4 is using a gradual expansion strategy, and the supply caps on certain Spokes may already be full when you try to operate. Check the current capacity of the target market before depositing.
If you are simply holding deposits in aToken form (such as aUSDC), the migration tool may offer a one-click conversion feature once it launches, similar to the V2 to V3 migration experience in 2022-2023. But until the tool is officially released, manual migration is the only path.

What You Should Do Now
Check where your positions are. If your positions on Aave V3 are operating normally and you are not encountering any issues, leave them alone and do nothing. V3's interest rates, incentives, and risk parameters have no planned changes that would materially affect user behavior.
If you are considering making a new move on Aave, first ask yourself: can V3 meet your needs? If the answer is yes, use V3. V3 has deeper liquidity, a longer security record, and a more mature interface. Only put funds on V4 when your strategy explicitly requires features that only V4 has—such as RWA lending, a specific Spoke market that is only deployed on V4, or a new mechanism you particularly value.
If you decide to try V4, start with a small position. Get familiar with how the Hub and Spokes interact first, and confirm that your wallet and the DeFi tools you use (such as Zapper or DeBank) can correctly recognize positions on V4. V4 is a completely new contract architecture, and third-party tool integration may still be incomplete.
There is no migration deadline. You do not need to move funds from V3 to V4 out of FOMO, and you do not need to act early out of fear that V3 will be shut down. The official team has clearly said V3 will continue to run. The choice is in your hands.
