原标题:详解 AAVE V4 升级:用模块化重塑借贷,老币能否迎来又一春?


25日晚间,AAVE创始人Stani宣布即将上线AAVE V4的帖子迅速吸引了大量关注与讨论,而近期AAVE与WLFI关于7%代币分配提案的争议也在市场中闹的沸沸扬扬。

一时间,市场的关注度都汇集在了AAVE这个老牌借贷协议上。

虽然AAVE和WLFI的争议暂时还没有一个最终定论,但在这场“闹剧”背后,似乎展现了一副别样的景象——“流水的新币,铁打的AAVE”。

随着越来越多新币的出现,在链上固定的代币借贷需求的刺激下,AAVE 无疑拥有着良好的基本面和催化剂。

此次V4更新,或许可以让我们看清其在DeFi领域未来的强大竞争力,以及其业务量不断上涨的根源所在。

从借贷协议到DeFi基础设施

当我们讨论AAVE V4时,首先需要理解一个关键问题,为什么市场对这次升级有期待?

从2017年的ETHLend,到今天386亿美元TVL的DeFi巨头,作为老牌协议,AAVE 过去的每个版本更新,实际上都在做优化,并且能够在不同程度上影响链上资产的流动性和玩法。

AAVE的版本史,其实就是DeFi借贷的进化史。

2020年初,V1上线时,整个DeFi锁仓量还不到10亿美元。AAVE采用流动池替代P2P模式,让借贷从"等待撮合"变成"即时成交"。这个改动帮助AAVE快速获得市场份额。

V2在2020年底推出,核心创新是闪电贷和债务代币化。闪电贷催生了套利和清算生态,成为协议重要收入来源。债务代币化则让头寸可以转让,为后续的收益聚合器铺平了道路。2022年的V3 主打跨链互通,让更多链上资产得以进入AAVE,成为多链流动性的连接器。

更重要的是,AAVE已经成为了定价基准。DeFi协议在设计利率时,都会参考AAVE的供需曲线。新项目在选择抵押率时,也会对标AAVE的参数。

不过尽管是基础设施,但V3的架构限制越来越明显。

最大的问题是流动性割裂。当前AAVE在以太坊有600亿美元TVL,Arbitrum只有44亿,Base更少。每条链都是独立王国,资金无法高效流动。这不仅降低了资金效率,也限制了小链的发展。

第二个问题是创新瓶颈。任何新功能都需要走完整的治理流程,从提案到实施往往需要数月。在DeFi快速迭代的环境下,这种速度显然跟不上市场需求。

第三个问题是定制化需求无法满足。RWA项目需要KYC,GameFi需要NFT抵押,机构需要隔离池。但V3的统一架构很难满足这些差异化需求。要么全部支持,要么全部不支持,没有中间地带。

这就是V4要解决的核心问题:如何让AAVE从一个强大但僵化的产品,变成一个灵活开放的平台。

V4 升级

根据已公开的信息,V4的核心改进方向在于引入"统一流动性层"(Unified Liquidity Layer),采用Hub-Spoke模型来改变已有的技术设计甚至是商业模式。

Hub-Spoke:解决既要又要的问题

简单来说,Hub汇集所有流动性,Spoke负责具体业务。用户永远通过Spoke交互,每个Spoke可以有自己的规则和风险参数。

这意味着什么?意味着AAVE不再需要用一套规则服务所有人,而是可以让不同的Spoke服务不同的需求。

比如,Frax Finance可以创建一个专门的Spoke,只接受frxETH和FRAX作为抵押品,设置更激进的参数;与此同时,一个"机构Spoke"可能只接受BTC和ETH,要求KYC,但提供更低的利率。

两个Spoke共享同一个Hub的流动性,但彼此风险隔离。

这种架构的精妙之处在于,它解决了"既要又要"的难题。既要深度流动性,又要风险隔离;既要统一管理,又要灵活定制。过去这些在 AAVE 里是矛盾的,但 Hub-Spoke 模型让它们可以共存。

动态风险溢价机制

除了 Hub-Spoke 架构,V4 还引入了动态风险溢价机制,革新了借贷利率的设定方式。

不同于 V3 的统一利率模型,V4 根据抵押品质量和市场流动性动态调整利率。例如,WETH 等高流动性资产享有基础利率,而 LINK 等波动性较高的资产需支付额外溢价。这种机制通过智能合约自动化执行,不仅提升了协议的安全性,还让借贷成本更公平。

智能账户

V4 的智能账户功能让用户操作更高效。过去,用户需要在不同链或市场间切换钱包,管理复杂头寸费时费力。现在,智能账户允许通过单一钱包管理多链资产和借贷策略,减少操作步骤。

一个用户可以在同一界面内调整以太坊上的 WETH 抵押品和 Aptos 上的借款,无需手动跨链转移。这种简化的体验让小额用户和专业交易者都能更轻松地参与 DeFi。

跨链与 RWA:扩展 DeFi 边界

V4 通过 Chainlink CCIP 实现秒级跨链交互,支持 Aptos 等非 EVM 链,让更多资产无缝接入 AAVE。比如,一个用户可以用 Polygon 上的资产抵押,在 Arbitrum 上借贷,全部在一笔交易中完成。此外,V4 整合现实世界资产(RWA),如 tokenized 国债,为机构资金进入 DeFi 开辟新路径。这不仅扩大了 AAVE 的资产覆盖,也让借贷市场更具包容性。

市场反应

虽然本周AAVE跟随加密市场大盘经历了暴跌,但其今日反弹力度明显强于其他头部DeFi标的。

AAVE代币在本周经历加密市场经历暴跌后24小时内全网交易量高达1872万美元,远远高于Uni的720万美元和Ldo的365万美元,反映出投资者对协议创新的积极响应,而交易活跃度提升也进一步增强了流动性。

TVL则更直观体现了市场对其认可程度,相较于8月初,AAVE的TVL量级本月飙升19%至最高接近700亿美元关口创下历史新高,当前位于ETH链上TVL排名第一。这一增长远远超越DeFi市场平均水平,TVL的增加也从另一方面验证了AAVE V4多资产支持策略的有效性,或许暗示着机构资金已经悄然入场。

根据TokenLogic数据显示,AAVE净资产总额已经创下1.327亿美元(不包含AAVE代币持仓)的新高,在过去一年内增长约130%。

链上数据方面,截止至8月24日,AAVE上未平仓合约超4.3亿美元,创下六个月内新高。

除了直观的数据,AAVE此次升级也引起了社区的广泛讨论,目前V4放出的前置信息也获得了大量的支持和认可,尤其是在资金利用率和可组合DeFi上,让市场看到了更多的可能性与潜力。

Make DeFi great again

结合目前已经披露的更新内容来看,AAVE这次升级很有可能会带领DeFi市场再上一个台阶,模块化架构、跨链拓展和RWA整合这些升级亮点不仅点燃了市场热情,同样也推动了价格和TVL的上升。

而其创始人Stani似乎也对V4升级后的对DeFi赛道的影响充满信心。

或许在不远的未来,AAVE会借着加密牛市到来的流动性“东风”扶摇直上,开启无限可能。

Top Audit Guru Alerts: All DeFi is Unsafe, Withdraw Now!

Leading DeFi security auditor and OpenZeppelin founder Manuel Aráoz has issued a stark warning, declaring all DeFi protocols unsafe and advising the withdrawal of funds, even from established platforms like Aave and MakerDAO. This warning stems from the rapidly growing threat posed by AI-powered hacking tools. Aráoz highlights that AI agents can now identify and exploit smart contract vulnerabilities in minutes, a task that previously took expert teams weeks. This creates a critical asymmetry: defenders must patch every flaw, while attackers need only find one. Recent months have seen a surge in high-profile exploits, with billions lost in April and May alone across protocols like Drift Protocol, Kelp DAO, and THORChain. The acceleration is attributed to AI's ability to perform rapid code scanning, generate automated attack scripts, and even orchestrate social engineering and infrastructure attacks faster than human defenders can respond. The article cites Anthropic's powerful new AI model, Mythos, which demonstrated such proficiency in finding zero-day vulnerabilities that its public release was delayed over security concerns. This evolution fundamentally disrupts DeFi's risk-reward calculus. With yields on reliable protocols falling to single digits, users now face the potential of 100% capital loss for minimal returns. Aráoz's conclusion is that for most users, withdrawing funds to secure wallets is the most rational risk-management choice in the current landscape.

Behind Changxin Technology, Stands a Group of A-Share Companies

Changxin Technology, a leading Chinese DRAM (Dynamic Random Access Memory) manufacturer, has passed the review by the STAR Market listing committee, moving closer to an IPO. The company, seeking to raise 29.5 billion yuan, is the first to utilize the new "pre-review mechanism" on the STAR Market, expediting its approval process within five months. As China's largest and most technologically advanced integrated DRAM company, Changxin has achieved mass production of mainstream DDR5 and LPDDR5X products. It holds the fourth-largest global market share and ranks first in China, though it still trails behind industry leaders Samsung, SK Hynix, and Micron in areas like HBM technology. The company reported its first annual profit in 2025, with net profit surging to 24.762 billion yuan in Q1 2026, driven by booming AI-related demand. The IPO has drawn significant market attention due to Changxin's extensive and prestigious shareholder base. This includes state-backed funds like the National Integrated Circuit Industry Investment Fund II, industrial partner GigaDevice, internet giants (Xiaomi, Alibaba, Tencent), and several securities firms and A-share listed companies such as InfoMotion, Shangfeng Cement, and Hefei Urban Construction, which stand to benefit from the listing. The company's founder, Zhu Yiming, a pivotal figure in China's semiconductor industry who also founded GigaDevice, has committed to an unprecedented long-term lock-up of his shares and a massive personal equity incentive plan worth an estimated over 20 billion yuan for employees, excluding himself, upon listing.

When Vitalik Stops Blogging to Write Sci-Fi

Vitalik Buterin, founder of Ethereum, has announced a pause in his long-form technical blogging to instead write a science fiction novel exploring decentralized governance. The story, set in a fictional nation called Veridia, follows a member of a governance body that uses complex systems like quadratic voting, privacy-preserving audits, and AI-assisted decision-making to guide society through incentive structures rather than outright bans. This creative shift comes at a pivotal moment for the Ethereum ecosystem. The Ethereum Foundation has seen significant internal upheaval in 2026, with at least nine core contributors, including key protocol leaders, departing. Just days before his announcement, Vitalik published a statement addressing this turbulence, framing the Foundation as a "smaller ship" that will now focus on core principles like censorship resistance and security, while moving from a growth-oriented to a sustainability-focused organization. The novel's themes directly mirror Vitalik's long-standing technical interests in governance mechanisms. Community reactions are mixed: some see it as a thoughtful exploration of ideas through narrative, while others view the timing—amidst core team departures and a significant drop in ETH's price—as pointedly symbolic. The move is also interpreted as a personal transition, signaling Vitalik's evolving role from a central executive figure to one of many decentralized thought leaders within the Ethereum ecosystem.
