The main innovation of the update is the Hub and Spoke architecture. Assets are now stored in central hubs (Liquidity Hubs). Branches (Spokes) connect to them with individual collateral rules, risks, and liquidation mechanisms.

Users deposit capital through Spokes, after which the funds are transferred to Liquidity Hubs. They become available to all pools on the platform. 

To facilitate interaction, the protocol team has released a free interface, Aave Pro. 

At launch, the application features three hubs:

• Core Hub — the main market of the platform;
• Prime Hub — a pool for suppliers with strict collateral rules;
• Plus Hub — a venue for trading strategies with stablecoins.

The code was audited by firms Trail of Bits, Blackthorn, ChainSecurity, and participants from the Sherlock platform, while the architecture was developed with the involvement of Certora. 

Earlier in March, Aave Labs co-founder Stani Kulechov commented on recent governance conflicts within the protocol and discussed the future of the DeFi sector.
