DeFi 一周思考:USDT0 全链扩张,老将抱团回归

深潮Publicado a 2025-05-21Actualizado a 2025-05-21

如果RWA如预期爆发,那么 $LINK 是一个很好的标的。

ETH 升级 RWA、正在做饭、DeFi 巨头抱团开启专属乐高时间,最近一周对 DeFi 的思考:

1/ ETH在最近半个月迎来大幅上涨,恰逢Pectra升级 (1) 个人觉得上涨跟这个有点关系,但不是主导 (2) 更多的是过度fud了,另外有ETF质押通过预期 (3) 此前ETH/BTC的汇率已经逼近最低点 不过这次升级的内容还是非常值得看一下,展开讲的话有点长,总结整理到gitbook了

2/ DeFi巨头抱团之 Aave Uniswap

Aave 计划推出 Uniswap V4 Hook,支持Uni V4 LP抵押借款GHO,这个计划需要从Uniswap DAO申请一部分资金,作为回报未来会将 GHO 的借贷利息收入与 Uniswap DAO 分享。

这是目前实用性最强的Hook,两大巨头同时受益。 提升LP的资金效率,Hook的组合性和灵活性开始显现出来。有了头部项目带头,后续能期待更多的创新。

3/ DeFi巨头抱团之 Aave Pendle Ethena

 (1) Ethena PT tokens集成到Aave,需求旺盛 (2) Ethena 继续加深与Aave的集成上线USDtb,提升USDe和sUSDe的供应上限,同时提升PT token的上限。 PT进入Aave以后: 爱好循环贷的老DeFi们开始工作了,又是一个三边受益的合作,随着DeFi蓝筹开始成熟,会进入DeFi头部项目的专属乐高时间。它相较于DeFi Summer乐高的稳定性更强,容量更大。

4/ Unichain流动性挖矿情况

(1) Unichain流动性挖矿产量减半 (2) 对WBTC Pool的激励将发生迁移 Gauntlet的说法是超额完成了KPI,所以调低了收益,TVL没有下降太多,收益仍然在市场可接受的范围,需要注意的是7天后对WBTC相关池的奖励会逐渐转移到WBTC0(OFT版本),Unichain目前和L0深度绑定。

5/ SSV Network宣布了SSV 2.0测试网上线 提出一个新概念bApps 新类型的去中心化应用程序,直接利用以太坊验证器来确保安全,而不是依赖额外的资本。验证者可以通过为 bApps 提供安全服务赚取额外收益。

乍一听就是Restaking,实际还是有点区别: Restaking 将已staking的ETH锁定到新协议中,以为这些协议提供安全性。

这些资产是可以被slashing的,如果协议出现问题,验证者的资产可能会损失。

以太坊本身也可能受到影响。SSV 2.0的特点就是验证者的staked ETH不会因协议问题而被slashing,保护了以太坊免受级联风险。这意味着如果 bApps 出现问题,不会影响到以太坊主网的稳定性。

由于Restaking找客户的能力在现阶段比较有限,没有产生足够需求,所以这项服务可能在短时间内很难得到关注,从机制上来说SSV 2.0确实具备自己的特点,书本上来看也是优于Restaking。

回到DVT这个赛道本身,上个周期没有站住,在这个周期更难了,优势是需求是比较确定的,但问题是多数会被巨头整合,现在SSV和Obol都在主动变局,希望能从其他角度破圈,可以关注,有待观察。

6/ Obol宣布Obol Stack

Obol Stack 的这个设计是把验证器的自主运行打包了,等于人人都能直接调用并部署验证器节点、排序器。官方/第三方将这种基础设施打包成"App "发布到Obol App Store,用户直接获取并部署自己的节点。

这个离vitalik最初提倡的每个人在世界每个角落都能够运行以太坊节点,更近了一步。

7/ USD₮0 正在快速扩张

USDT0是一种由Tether和LayerZero联合推出的全链稳定币,基于L0的OFT技术实现全链流通,已经支持很多主流链。

这种方案直接竞争的就是USDC CCTP,区别在于USDC的方案更加原生和中心化,USDT0则依靠LayerZero,而USDT0在生态方面也得到了很多资源。

比如可以在Unichain上挖矿、在Flare上提供流动性获得生态补贴。

总体来说,会有很多Farm的机会,背景来看也算是Tether支持的,未来会在链上看到越来越多的USDT(USDT0)了。

8/ 关注到了两个老DeFi的动作

 (1) Liquity V2宣布即将重新上线,修复漏洞 (2) Alchemix预示即将回归 Liquity V2在2025年4月15日左右遭遇了安全漏洞,导致协议暂停运营。这次漏洞涉及一个复杂的攻击,重新上线后有待观察,实际上V1是我比较喜欢的一个设计,虽然V1在效率和扩展上有一些问题,但简约且有效,已经被N多个项目fork,V2的改动是一次突破,但安全性上的处理确实有一些减分,观察中。

Alchemix是上个牛市DeFi 2.0时期的几个亮点项目之一,近期可能要开始重塑,不过相较于Euler和Maple,Alchemix是偏社区性质的项目,如果拿不出什么杀招,竞争力比较有限。可先关注着。

9/ RWA 动作很多

Securitize为贝莱德代币化基金发行用于DeFi的包装版本,这个我觉得算是比较重要的一条

其他还有: (1) VanEck与Securitize合作推出代币化基金 (2) Stripe 推出稳定币金融账户 (3) Arbitrum批准将35M ARB分配给代币化美国国债 (4) Aave旗下RWA平台Horizon与AntChain合作,允许抵押RWA资产借贷稳定币 比较有意思的一个,Stripe金融账户支持的USDB,它的激励机制是使用 USDB 时,会将底层资产的收益(例如货币市场基金的利息)以费用的形式支付给开发者。

10/ RWA另外值得一说的就是,Chainlink、J.P. Morgan和 Ondo Finance 联手实现代币化美国国债的跨链结算。

Ondo Chain是一个公链,而Kinexys是一个许可链。这两种链的互操作性需要额外的技术支持,目前采用的是Chainlink方案。

预计未来在RWA跨链结算这个领域,Chainlink已经占了一定的生态位,如果RWA如预期爆发,那么 $LINK 是一个很好的标的,同时有预言机龙头的位置兜底。

In Such a Crowded Cross-border Payment Track, Where Does the Next Stop Lie in the Future?

The crowded cross-border payments industry faces a paradox: intense competition above water with financing and narratives, while beneath, price wars and shrinking margins in basic PSP services are common. The path forward lies not in simple "cross-border" solutions but in deep **localization**. Success requires mastering the fragmented and tightening regulations of fiat currencies in each market—the "last mile" of compliance, banking, and settlement. Many Chinese PSPs have succeeded by following Chinese merchants overseas but have not deeply penetrated mainstream local merchant ecosystems abroad. Their strong product capabilities need to be applied to new, complex markets. The future belongs to companies that evolve from single-channel providers to **cross-border capital network operators**. This means moving beyond competing on transaction fees to creating internal networks that optimize capital efficiency through multi-directional matching, netting, and position reuse across countries and currencies. For Web3 and stablecoins, the key is integration, not replacement. Stablecoins offer efficiency gains but cannot bypass the foundational trust, compliance, and legal frameworks of traditional finance. The realistic path is the gradual adoption and "taming" of Web3 technologies by established financial institutions. The ultimate solution is a **dual clearing infrastructure** combining deep local fiat capabilities (local accounts, compliance, banking) with lightweight stablecoin-native capabilities (on-chain settlement, wallets). The biggest opportunity lies not in oversaturated mainstream corridors but in complex, underserved regional corridors (e.g., specific CIS, Middle East-Southeast Asia, or Latin American trade pairs). The winners will be those who build hard-to-replicate, deep capabilities in these areas—acting as the essential "clearing shovels" or infrastructure providers. The future keywords are **more local, more networked, and more stablecoin-native**. High-profit opportunities remain in the non-standardized, difficult-to-replicate deep waters of the industry, requiring genuine on-the-ground presence and long-term patience.

Lightning Fast Five-Whip Combo! Strategy's Self-Rescue Plan Officially Released

Strategy, amidst the STRC de-pegging crisis, has unveiled its "Digital Credit Capital Framework" self-rescue plan. The five-part framework includes: 1) **Cash Reserves**: Management of ~$2.55B in USD reserves, dedicated solely to covering ~17.4 months of preferred stock dividends and debt interest, with a 12-month minimum coverage floor. 2) **Dividend Policy**: STRC's dividend yield rises to 12% from July 1st, with monthly reviews. Strategy clarifies de-pegging does not automatically trigger further hikes. 3) **Preferred Stock Buyback**: A $1B authorization, prioritizing STRC repurchases to support its price, reduce future dividend obligations, and signal commitment, using funds separate from dividend reserves. 4) **Common Stock Buyback**: A separate $1B authorization for MSTR stock, aimed at creating shareholder value when the stock is deemed undervalued, establishing a two-way capital management mechanism. 5) **Bitcoin Monetization**: Formal authorization to sell BTC (up to $1.25B earmarked) to build USD reserves, cover dividends/interest, or fund buybacks, marking a strategic shift where BTC becomes a managed asset rather than a strictly "hold-only" reserve. Market reaction saw MSTR and STRC shares rise pre-market, while BTC remained stable. The plan aims to restore confidence in STRC, ensure dividend sustainability, and reopen Strategy's funding channels.
