Aave V4 Goes Live on Ethereum Mainnet Introducing a "Center-Radius" Architecture

2026.03.30 21:06:59

March 30th saw the official deployment of Aave V4—the fourth-generation decentralized lending protocol—on the Ethereum mainnet. Aave V4 features a new “hub-and-spoke” architecture, centralizing liquidity at the “hub” for various financial markets to connect via “spokes.” Each spoke can independently set risk parameters and lending environments, aiming to support a broader range of real-world credit markets, including structured loans, fixed-rate lending, and asset tokenization-backed credit. Aave Labs CEO Stani Kulechov noted the team will follow a “controlled launch” approach, initially governed by the DAO. At launch, major on-chain apps including Lido, EtherFi, Kelp, Ethena, and Lombard plan to deploy spokes first. For risk management, V4 introduces a “credit limit” mechanism that caps exposure limits for each use case. Additionally, the system supports more precise collateral-level risk pricing. Notably, V4 has undergone over a year of security testing, and its core protocol has never been hacked across multi-chain deployments. Kulechov added that V4 will prioritize the “borrowing side,” tapping into Aave’s on-chain liquidity to drive significant borrowing demand and channel it back to the real economy. This launch comes amid months of governance turmoil within Aave DAO. Kulechov recently put forward the “Aave Will Win” reform proposal, which aims to turn Aave Labs into a DAO subsidiary to streamline the governance structure.

Quant will provide technical support for The Clearing House’s tokenized deposit clearing network.

According to an official announcement, Quant has announced it will provide technical support for The Clearing House’s "On-Chain Currency Initiative" to build an interoperable payment network for financial institutions. Quant will oversee the network’s interoperability, orchestration, and transaction management layers, and integrate existing fiat payment systems including RTP and CHIPS, enabling financial institutions to access clearing and settlement capabilities for tokenized deposit transactions. The initiative aims to meet the growing demand from enterprises and financial institutions for faster, more automated, and flexible fund flow methods, enabling instant payment settlement and supporting auto-triggered transactions when pre-set conditions are met, thereby reducing manual operations and processing delays. Tokenized deposits are the digital form of traditional bank deposits, retaining the regulatory and protection mechanisms of conventional deposits while being recorded and transferred on-chain. The network will be applied to use cases including corporate treasury management, liquidity management, cross-border payments, and digital asset settlement, and is expected to open to participating institutions in the first half of 2027. The Clearing House stated that its U.S. payment network processes over $2 trillion in daily clearing and settlement volume, and this partnership will provide infrastructure support for financial institutions of all sizes to participate in the tokenized deposit network.

SlowMist's Cosine questions THORChain's double standard: the protocol intervened in its own hack incident, yet insists it has "no right to interfere" in external related events.

SlowMist founder Yu Xian stated in a post that the Bitget hack is a widespread, public, high-value and clear hacker incident, with North Korean hacker fund traces quickly linked. Circle, Tether and other platforms acted promptly to freeze relevant funds, especially Circle froze the USDC held by the hackers. THORChain, which itself was previously hacked, intervened quickly as a self-proclaimed "decentralized" platform. However, when facing major industry events, it ignored communication with all parties, compared itself to Bitcoin and Ethereum, claimed to be decentralized, asserted it had no right to interfere, and continued to enjoy large cross-chain fees contributed by North Korean hackers. Decentralization is not a slogan; in major industry events, the key is to clarify which problems need to be addressed collectively.
