TLDR
- Aave V4 is coming, aiming for a Q4 2025 launch
- V4 is packed with features, including a new interface.
- The team is striving to stay one step ahead and maintain its position as the leading DeFi platform for lending and borrowing, while also incentivizing institutions to utilize its services.
If you’ve been hanging around the DeFi playground, you’ve probably heard about Aave V4. If you’re brand new, you’ve probably at least heard the name in passing. They’re a big deal with a group of devs that are constantly pushing the envelope as far as lending and borrowing innovation.
A major upgrade is on the way, designed to make Aave more flexible, efficient, and user-friendly. This one is a bit technical and nerdy, but we’ll simplify as much as possible. Time to get after it.
What Was Wrong with Aave V3?
Well…nothing. But DeFi isn’t a TradFi bank. None of the top teams in this space are ever content for long. That’s not why they do what they do.
Aave V3 is a beast, but it has its limits. Think of it like a giant, single building. Every time Aave wants to expand to a new blockchain or add a new feature, it’s like adding a new wing to that building. It works, but it’s clunky, and the construction can be inconvenient for people.
This “monolithic” design has a few key problems:
- Fragmented Liquidity: Every new deployment on a new chain creates a separate pool of money. It splits up the liquidity, which can lead to worse rates.
- Inflexible Risk: In V3, the interest rates don’t really care about what you’re using as collateral. Borrowing against a solid asset like ETH is treated similarly to borrowing against a newer, more volatile token. It’s a one-size-fits-all approach.
- Incentive Headaches: To get new markets going, Aave often has to rely on token rewards to attract liquidity. The problem? A lot of that capital is just chasing rewards and disappears as soon as the incentives dry up. Classic “mercenary capital” dilemma.
Aave V4 is designed to fix these issues with a completely new structure.
The Hub and Spoke Model
The star of the Aave V4 show is the new “Hub and Spoke” architecture. It’s a fancy way of saying they’re breaking the protocol into smaller, more manageable pieces.
- The Liquidity Hub: A new central pool of money. Instead of having separate liquidity pools on different networks, all the capital lives here. It’s the core of the whole system.
- The Spokes: These are specialized modules that connect to the hub. Each spoke is designed for a specific purpose. You could have a spoke for standard borrowing, another for eMode (for borrowing similar assets), and another for isolated, riskier assets.
The new design is a game-changer that enables the addition of new features and markets as “spokes” without disrupting the core protocol. Everything plugs into the same central hub, which means liquidity is no longer fragmented. It’s a much smarter, more modular way to build.
What’s Coming in Aave V4?
Alright, let’s get to the features. The development team has outlined a plan for what will be available at launch and what will be added later. Here are the highlights.
Features Available at Launch
These are the goodies you can expect to see on day one of the V4 release.
Risk Premiums
This is one of the biggest changes. Instead of a single interest rate for everyone, V4 introduces a system that prices risk based on the quality of your collateral.
Here’s how it works:
- The hub sets a base interest rate based on overall supply and demand.
- Each asset you supply as collateral has a Collateral Risk score. High-quality assets like ETH will have a low score, while more volatile tokens will have a higher one.
- The protocol combines the risk scores of all your collateral to create a User Risk Premium. This is an extra fee added to your borrowing rate.
In simple terms: if you use strong, stable assets as collateral, you’ll pay a lower interest rate. If you use riskier assets, you’ll pay more. This new system rewards responsible borrowing and allows Aave to support a wider range of assets without putting everyone at risk.
Dynamic Risk Configuration
Currently, when Aave governance changes a risk parameter (like how much you can borrow against an asset), it affects everyone immediately. That can lead to surprise liquidations. That’s not a fun kind of surprise.
V4 introduces “Risk-Config IDs.” When a parameter is changed, a new configuration is created. Existing positions remain under the old rules, while new positions use the updated ones. Your position only updates to the new rules when you take a risk-increasing action, like borrowing more. This makes the system much more predictable for users.
A Smarter Liquidation Engine
Getting liquidated sssuuuccckkkksss. The new Liquidation Engine aims to make it a little less painful. Instead of liquidating a fixed percentage of your position, it will only repay enough debt to get your account back to a “healthy” state.
Plus, the liquidation bonus (the discount the liquidator gets) will be dynamic. The riskier your position gets, the bigger the bonus, incentivizing quick action when it’s needed most.
A Fresh New Interface
To go along with all the backend changes, Aave is building a new user interface. It will provide a single dashboard to view all your positions across different Spokes, making it easier to manage your funds.
Features Planned for After Launch
The innovation doesn’t stop on day one. Here are some of the exciting features the team is researching for future updates.
- Permissionless Deployments: Imagine being able to spin up your own private Aave liquidity pool. The hub and spoke model makes this possible, allowing institutions or other projects to create their own isolated instances.
- Stronger GHO Integration: The team is exploring ways to more deeply integrate Aave’s stablecoin, GHO. Potential features include things like settling liquidations in GHO or even allowing native GHO minting against collateral.
- Automated Treasury Management: A new system could automatically convert protocol fees into a target asset like ETH, making treasury management more efficient and reducing the need for constant governance votes.
Wen? Soon. But Seriously. It’s Coming Soon.
The codebase is feature-complete and currently undergoing a rigorous security audit process with multiple firms. Service providers have already started testing, and a public testnet is the next major milestone.
Aave hasn’t provided a firm release date yet, but they aim to publish the full codebase and architecture documentation for community review soon. This will be followed by the public testnet, which will let everyone get a feel for the new system before it goes live on mainnet.
Aave V4 represents a massive leap forward for the protocol. By adopting a more modular and capital-efficient design, the team is creating a platform that is not only more powerful but also safer and more user-friendly.
For users, this means better rates, more predictable risk, and a more streamlined experience. For the broader DeFi ecosystem, it unlocks new possibilities for innovation, allowing developers to build on top of Aave in ways that were never possible before.
We’ll keep you guys updated and the Aave team releases more information. Happy lending, borrowing, and looping.
