This version features a Hub and Spoke architecture, allowing assets to be stored in central hubs known as Liquidity Hubs. These hubs are connected to various spokes that operate under distinct collateral rules, risks, and liquidation processes.
Capital is deposited through the spokes and subsequently routed to the Liquidity Hubs, thereby making funds accessible to all pools on the platform.
In addition, Aave has introduced a new user-friendly interface called Aave Pro to enhance the overall experience.
The launch includes three primary hubs:
- Core Hub — the platform's main market;
- Prime Hub — designed for providers with stringent collateral requirements;
- Plus Hub — aimed at trading strategies utilizing stablecoins.
The protocol's code has undergone audits by several firms, including Trail of Bits, Blackthorn, and ChainSecurity, with architectural contributions from Certora.
In related news, Aave Labs co-founder Stani Kulechov recently addressed governance issues within the protocol and shared insights on the future landscape of the DeFi sector.
