Aave V3的推出将进一步提高资本效率,安全性和跨链功能。

去中心化借贷协议Aave在北京时间3月16日晚宣布正式推出Aave V3,并表示已上线Polygon、Arbitrum、Avalanche、Fantom、Harmony和Optimism。
此外,以太坊主网上线日期尚未确定,部署至Starkware开发的Starknet的提案也已于近期通过,部署至IoTeX的提案已经在治理论坛发起。
这意味着Aave V3可能将至少在9个区块链网络部署,成为覆盖度最高的DeFi借贷协议。相比之下,另两个DeFi借贷协议巨头MakerDAO与Compound目前仅支持以太坊主网,凸显出Aave坚定的多链发展战略。
而在本次V3更新中,Aave也将多链流动性作为主要亮点推出,该功能允许用户进行跨链借贷,“这意味着用户可以在以太坊主网中存入资金,但可以从 Polygon 借钱并在 Avalanche 上偿还。”Aave 创始人 Kulechov 称。
此外,Aave V3的亮点还包括资本效率、隔离模式、新型风控策略、降低Gas费等。据官方介绍,Aave V3的推出将进一步提高资本效率,安全性和跨链功能,促进整个协议生态系统的发展和增强去中心化。
以下是链捕手对该版本功能的具体梳理与介绍。
资产跨链流动(Portal)
Aave V3引入的门户功能支持用户资产通过不同网络在Aave V3市场之间无缝移动。其核心功能就是通过用户在原始网络(例如eth)上销毁aToken,在目标网络上(例如Polygon)铸造它们,即可将用户提供的流动性从一个网络转移到另一个网络。围绕这个功能所构建的网络互联被称为Port(端口)。
这种跨链功能保持不同链之间的记账,同时支持用户追求收益套利和其他策略。目前,Aave支持在Avalanche、Ethereum和Polygon上运行,每条链上都有数十种具有可变的借贷和利率资产特征。除了利率,各链之间的流动性需求可能会有很大差异。Aave创始人Kulechov预计随着新的跨链门户功能上线,这些回报和需求波动将“趋于平缓”。
Portal将能够桥接Connext、Hop Protocol、Anyswap、xPollinate和其他利用Aave协议流动性以促进跨链交互的解决方案。Aave治理将能够在收到提议后授予对端口的任何跨链协议访问权限。
Aave发言人表示,“跨链门户将使用户能够自行决定将自己的流动性从一个网络转移到另一个网络。它支持协议在各种网络上的每次迭代都能随着资本化的深度而快速扩展。”
高效模式(eMode)
高效模式支持借款人确保其能够用自己的抵押品获得最高的借贷能力。高效模式或“eMode”支持用户利用极高的贷款与价值比,只要其以他们作为抵押品存放的相同资产进行贷款——在某些情况下,LTV甚至高达98%。“这里的主要思想是,一旦我们拥有不同种类的稳定币,例如欧元稳定币、英镑稳定币,那么你基本上可以在链上进行外汇交易,”Kulechov说。

Aave


其中代码支持Aave Governance根据生命周期价值、清算门槛、清算奖金和自定义价格预言机(可选)参数对资产进行“分类”。这些因素会将V3中的每个不同资产设置为特定类别。如果借款人按类别限制借入的资产,则eMode为借款人提供了更多的资金获取途径。换言之,在eMode中,借款人可以选择他们想要借入的资产类别。“类别”通常是指与同一基础资产挂钩的一组资产。例如,与美元挂钩的稳定币、与ETH挂钩的资产等。
如果用户在eMode中自行选择使用Aave协议,当该用户提供与用户抵押品相同类别的资产时,借贷能力(LTV)和维持保证金(清算阈值)将被eMode类别配置覆盖以允许更高的资本效率。
例如:
协议定义 eMode 类别 1 (稳定币):97% 生命周期价值;98% 清算门槛;2% 清算奖金;没有自定义价格oracle(预言机)。
1.Karen 选择 eMode 类别 1 (稳定币);2.Karen 提供 DAI (通常有 75% LTV);3.Karen 可以借入类别 1 (包括 DAI)中的其他稳定币,其借贷能力由 eMode 类别定义(97%)。;4.因此,Karen的资本效率提高了 22%。
注意:在这个例子中,Karen 可以提供其他非第 1 类资产作为抵押品;但是,只有属于用户选择的相同 eMode 类别的资产才会具有增强的特定于类别的风险参数。V3 eMode 最多可支持 255 个类别。
隔离模式
隔离模式旨在允许Aave治理在协议上创建新的资产市场时制定风险缓解功能。
除了更强的资本流动性外,v3还大大简化了新形式抵押品的引入,尽管其效用已被剥离。“V3主要是关于两件事:风险意识/缓解和资本效率,”Kulechov说,“在风险意识方面,我们实际上可以降低新抵押品进入生态系统的风险,且仍然允许,但限制敞口。”

Aave


Aave正面临来自Euler、Kashi和Rari等借贷平台越来越大的压力,这些平台可以通过无许可的借贷池更好地满足长尾或外来资产的需求。因此,v3引入了“隔离市场”,这实际上是一个快速通道,允许Aave治理机构以比目前更快的速度将资产作为抵押品上市,但只是作为单一的抵押品来源,而不是权力束。此外,隔离市场将具有由DAO治理控制的供应上限。
“随着时间的推移,随着资产的成熟,上限可提高,并最终关闭特定资产的隔离模型。因此,它支持资产可扩展性,”Kulechov补充道。
当社区成员提交在V3上创建新资产市场的治理提案时,该提案可以寻求将资产列为“隔离抵押品”,以便提供这些“隔离”资产的用户只能借入Aave Governance已“许可”的稳定币以隔离模式借款,最高达到指定的债务上限。当用户提供“隔离资产”作为抵押时,该用户只能使用该资产作为抵押;即使用户向协议提供其他资产,用户也只能通过这些资产赚取收益,而不能将这些资产用作抵押品。
例如:
Chad提供TOKEN2作为抵押品。TOKEN2是一种隔离资产,最高债务上限为1000万美元,USDT、DAI和USDC作为“可借用”资产。在提供TOKEN2作为抵押品后,Chad将能够借入高达1000万美元的USDT、DAI和USDC。即使Chad提供另一种资产,假设是ETH,V3智能合约也不会允许Chad以这些资产为抵押借款。尽管Chad仍将通过提供的ETH赚取收益。如果Chad希望将所有资产用作抵押品并退出隔离模式,其只需进行交易以禁用TOKEN2作为抵押品(受智能合约中有关抵押品比率、清算等的所有通常限制)。
当Aave Governance对取消与该资产相关的债务上限的提案进行投票时,TOKEN2也可以退出隔离模式。
风险管理功能
V3技术为Aave Governance提供了进一步增强的风险管理机制,以防止协议破产。措施如下:

  • 供应和借用上限(Supply and Borrow Caps):Aave Governance将能够配置借用和供应上限。借款上限可最大限度地减少流动性池的破产,供应上限可减少协议对特定资产的风险,并有助于防止无限铸币或价格预言机操纵等攻击。
  • 精细借款权力控制(Granular Borrowing Power Contro):Aave Governance将能够改变未来借款交易的抵押因素,而不影响现有的借款头寸或触发清算。
  • 风险管理员(Risk Admins):V3引入了Aave Governance在“许可列表”上注册实体的能力,这将使这些实体能够在不需要治理投票的情况下更改某些风险参数。
  • 价格预言机哨兵(Price Oracle Sentinel):Sentinel特性专为L2协议设计,用于处理排序器的最终停机时间(也可扩展到L1上以处理其他事件)。它引入了清算宽限期,并在特定情况下禁止借贷。


添加新资产流程去中心化
V3还引入了“Asset Listing Admins”(资产列表管理员)的新概念。借助此功能,Aave Governance 可以创建并向任何实体(甚至是智能合约)授予权利,以实施新策略以将资产添加到Aave协议,而不是通过链上投票。
其他特性
涉及代币传输的功能(例如,供应、偿还)支持EIP 2612许可,对于L2部署很关键;用户可以使用aTokens代替原来借入的底层资产来偿还借入的头寸;Aave Governance可以“允许”实体获得即时流动性;针对L2网络的特定设计,以改善用户体验和可靠性;通过模块化等促进和激励社区使用;所有功能的gas成本都降低了大约20-25%。
此外,其官方表示,V3代码库是一组独立的智能合约,与V2智能合约不兼容。一旦所有审计完成,并经过更多测试,V3代码将与主要V3存储库一起开源,用于部署在Ethereum、Avalanche和Polygon网络上。

What Happens When Two Miners Find a Block in the Same Second? How the 'Orphan Race' Unfolds

Bitcoin mining is a race without a real-time referee. A newly mined block must physically propagate across the global peer-to-peer network before consensus is reached on the chain's tip. This takes seconds, sometimes longer on congested connections. If a second miner finds a valid block before learning of a competing one, they build on their last-known version and broadcast their own block. For a short time, two equally valid blocks exist at the same height, creating a temporary chain split. The network resolves this not by voting or timestamps, but by Proof-of-Work: the chain that accumulates the most work becomes canonical. Blocks on the losing side are "orphaned" or "stale." Their miners lose the block reward and fees, though unconfirmed transactions return to the mempool. Usually, a single subsequent block resolves the tie. A notable two-block reorganization occurred on March 24, 2026. Antpool and Foundry USA mined competing versions of block 941,881 seconds apart. ViaBTC extended Antpool's chain, while Foundry extended its own, creating a one-block split. Foundry then pulled ahead by mining six consecutive blocks, making its chain the heaviest. All nodes switched to Foundry's chain, orphaning blocks from Antpool and ViaBTC. While such multi-block reorganizations are rare, the underlying race condition is common. Analysis shows about 9.2% of block intervals in a sample period were under 60 seconds, each representing a potential short-lived race. Fast relay networks have reduced propagation delays, making prolonged splits rarer. However, the event highlighted a trend of hash rate concentration, where well-resourced pools have a higher chance of winning any specific race and mining consecutive blocks, marginalizing smaller miners.

AmericanFortress proposed a scheme to protect crypto wallets from quantum threats

AmericanFortress has published a preprint detailing ZKPoSP, a cryptographic scheme designed to protect hierarchically deterministic (HD) cryptocurrency wallets from potential quantum attacks without requiring users to change their addresses. The proposed scheme replaces classical digital signatures with non-interactive zero-knowledge (NIZK) proofs, aiming to maintain compatibility with existing address formats. The company also introduced the QBIP32 scheme, intended to generate a signing scalar, a separate quantum-resistant proof, and a chain code in a single function call. According to the authors, QBIP32 can be applied to various elliptic curves of prime order, including secp256k1 and Ed25519. The post-quantum security of the scheme is described as "conjectured," relying on the quantum resistance of the underlying hash functions and NIZK proofs. However, for the scheme to function in a given blockchain network (like Bitcoin, Ethereum, or Solana), nodes would need to support verification of these new proofs instead of standard signatures—a capability currently not implemented. An implementation in Rust using RISC Zero reportedly takes 12–13 seconds to generate a proof and 9–10 milliseconds to verify it. The publication follows other industry efforts to address quantum threats, including reports from Galaxy on vulnerable assets, new hardware wallets like the PQ1, and consortiums like the Bitcoin Security Consortium pledging funding for post-quantum cryptography research. This new work specifically focuses on HD wallets and positions ZKPoSP/QBIP32 as a general mechanism for multiple curves and networks.

Weekly On-Chain Data Review: Robinhood Chain Explodes, FWA Goes Viral, Mantle Doubles Down on RWA

**Chain Data Weekly Digest: Vault Regulation, Robinhood Memecoin Surge, and FWA's NFT Gamble** * **Vault Managers Face SEC Scrutiny:** SEC Commissioner Hester Peirce warned that some DeFi Vault strategies could trigger investment advisor regulations. This may lead to licensing requirements, potentially sidelining smaller managers while bringing more traditional finance firms on-chain. The industry debates whether Vaults are purely code-driven or resemble discretionary portfolio management. * **Robinhood Chain's Memecoin-Led Boom:** Despite its initial RWA focus, Robinhood Chain has seen explosive early growth driven by memecoin trading and launchpads, which now dominate its DEX volume. The chain facilitates memecoin trading via tokenized stock pairs. It boasts over $800M in on-chain assets, $5B in stablecoin market cap, and strong fee revenue, positioning it as a consumer trading hub. * **FWA Revives NFT Activity with a Gamble:** The Fake World Assets (FWA) protocol, a gachapon-style system on Ethereum where users pay to randomly win deposited NFTs, has rapidly captured 10% of Ethereum's mainnet gas consumption in its first week. It demonstrates how simple, consumer-facing mechanics can reignite NFT engagement, attracting a broad user base. * **CEX Consolidation & DEX Growth:** The closures of BitMEX and BitMart highlight intense central exchange (CEX) competition and consolidation. Meanwhile, the DEX/CEX spot trading volume ratio hit a record high of 24.3% in July, signaling a shift of trading activity and innovation to on-chain venues. * **Mantle's RWA Focus at 3 Years:** Celebrating its third anniversary, Mantle Network is solidifying its role as a "full-stack distribution layer" for tokenized real-world assets (RWA). It ended Q2 with $1.2B in DeFi TVL, $955M in stablecoin market cap, and a growing suite of native RWA trading infrastructure like Fluxion and xChange.
