The new Aave V4 protocol is about to launch, bringing significant changes to the Decentralized Finance lending market.

Aave, as the largest lending protocol in the Decentralized Finance space, is about to launch the new version of the protocol, V4. The total value locked in the protocol has surpassed the $25 billion mark for the first time, making it the first lending platform in the Decentralized Finance sector to achieve this milestone. The development team is actively advancing the development of new features, aiming to further drive platform growth through risk parameter adjustments.

The new protocol will introduce multiple innovative features:

1. Unified Liquidity Layer: Introduce a series of modules to remove the original limitations of liquidity migration while adding new features such as cross-chain lending.

2. Dynamic interest rate adjustment: Automatically adjust the interest rate curve and inflection points based on market conditions, rather than relying on governance voting.

3. Liquidity Premium: The borrowing costs will rely more on the liquidity status of each token. Assets like ETH will maintain a no-premium status, becoming the benchmark currency, while other assets will adopt corresponding premium mechanisms based on their liquidity status.

4. Smart Account: Supports new features such as locking liquidity, disabling collateral functions, etc.

5. Dynamic Risk Allocation: The collateral rate is linked to the market conditions at the time of position establishment, providing greater stability for users' positions.

6. Clearing mechanism upgrade: including variable clearing parameters and reward mechanisms, while supporting batch clearing functionality.

7. Deep integration of GHO stablecoin: Implementing upgrades to the soft liquidation mechanism, paying stablecoin interest with GHO, and adding optimization features such as an emergency redemption mechanism.

The unified liquidity layer is a significant improvement that allows for the deployment of new lending modules or the decommissioning of old modules without the need to migrate liquidity. This architecture supports the addition or optimization of lending functions without altering the overall system. At the same time, it effectively addresses the liquidity fragmentation issues present in earlier versions of the protocol.

Cross-chain lending may be one of the most influential features, allowing users to deposit on one chain and borrow on another. This not only significantly enhances the platform's cross-chain liquidity potential but also creates new opportunities for market growth.

GHO is an over-collateralized stablecoin launched by Aave, with a current market value exceeding $220 million. The new protocol will introduce a flexible liquidation mechanism, drawing from the innovative lending liquidation automated market maker (LLAMM) model to streamline the liquidation process. Liquidation operations occur within a customizable range, and this mechanism guides the system to convert assets into GHO during market downturns and to repurchase collateral when prices rise.

Aave V4 has also introduced an emergency redemption mechanism to address extreme situations where GHO experiences severe and prolonged de-pegging. Once triggered, the platform will gradually exchange the collateral assets with the lowest health factor for GHO tokens based on the LLAMM design, in order to repay user debts.

Automating processes such as asset delisting and interest rate model adjustments helps reduce reliance on slow governance processes, especially when responding to market-driven changes. Aave is confident in the growth of its stablecoin GHO, which has seen significant improvements and deeper integration within the protocol.

In the foreseeable future, Aave is expected to continue to maintain its cornerstone position in the Decentralized Finance field. The success of the broader ecosystem highly depends on its continued leadership. After all, no other project can accumulate a total locked value at this level while maintaining the same level of security.
