The key innovation in this update is the Hub and Spoke architecture. Assets are now stored in central hubs (Liquidity Hubs), which connect to spokes that have individual collateral rules, risks, and liquidation mechanisms.
Users deposit capital through the spokes, and the funds are then routed to the Liquidity Hubs, making them available to all pools on the platform.
To enhance user experience, the protocol team has released a free interface called Aave Pro.
At launch, the application features three hubs:
- Core Hub — the main market of the platform;
- Prime Hub — a pool for providers with strict collateral requirements;
- Plus Hub — a venue for trading strategies involving stablecoins.
The code has been audited by firms such as Trail of Bits, Blackthorn, ChainSecurity, and members of the Sherlock platform, while the architecture was developed with the involvement of Certora.
As a reminder, in March, Aave Labs co-founder Stani Kulechov commented on recent governance conflicts within the protocol and discussed the future of the DeFi sector.
