写了一篇关于美债,赤字,稳定币和DeFi的文章 未来3-5年将会是美债继续泡沫化的一段时期,区块链技术使美债的购买群体从机构间接转为个人。 全世界都会成为美债的承销商,能帮美政府承销美债的生意都是好生意! > 属于美债承销商的4年:timzz.substack.com/p/401

在过去半年的各种hack事件中,Spark没有受到任何消极的影响。 这不是侥幸,是团队的克制和风控能力在背后做支持。 很多人在去年的时候,问Spark团队为什么不支持sUSD(x) 等类型稳定币的looping,也问团队为什么不多多支持抵押物类型和数量增加市场占有率。 我们的回答一直就是 [ 风控第一] & [追求长久类型的需求]。因此截至目前为止,Sparklend市场仅支持7种资产作为合格抵押借贷稳定币,预言机的机制设计也更具有鲁棒性。 [开放金融]+[严选市场] = [Low-risk DeFi]

I'm excited to be joining @SkyEcosystem to lead business development globally. Five months ago I met @RuneKek and the team. What I found was a group quietly but relentlessly executing on an ambitious vision. The numbers speak for themselves. $14.8B in AUM. ~$10.8B in USDS supply. The 3rd largest stablecoin globally, and home to sUSDS, the largest yield-generating stablecoin. This is the result of a great deal of operational discipline. Since its earliest days as MakerDAO, Sky has optimized for one thing above all: protect people's capital. The last few weeks in DeFi are a reminder of why that matters. What attracts institutional capital isn't the biggest number on a screen. It's the number you can trust is still there tomorrow. Financial services have one product. It's trust…and Sky has been building it longer than anyone in DeFi.

@jocyiosg 暂时不给补偿方案是问题一, 其次是aave利率曲线的设计问题,不足以激励用户提供稳定币流动性

𝗗𝗲𝗙𝗶 历史上最危险的囚徒困境 $2.3亿USD坏账悬而未决。Aave Collector 持有超过$2亿流动资产,LayerZero 刚完成$1.2亿融资——两家都完全有能力赔付。Aave在不到两天内已经流失了 $84.5亿 TVL,整个 DeFi 蒸发了 $132亿。每多拖一天,这个数字还在扩大。 但没有任何一方回应被盗的资产谁来负责,没有任何一方表态。他们在互相博弈,而整个 DeFi 在流血。 𝟮𝟬𝟮𝟬 年的 𝗗𝗲𝗙𝗶 精神去哪了? 2020年3月12日,ETH 跌到 $80,链上清算拍卖因流拍价格一度归零,MakerDAO 面临系统性崩溃。当时 MKR 基金会站出来提议拍卖 MKR 回购 ETH 填补坏账,社区大户纷纷参与竞拍。 那一次,以太坊社区和 DeFi 精神让所有人引以为傲——危机面前有人担当,有人行动。 今天呢?沉默。 我身边很多朋友不只是从 Aave 撤资——连 Spark、甚至其他 DeFi 协议的资金都在撤出。他们不是恐慌,他们是在用脚投票:如果这个生态连 260M的事情都没人愿意站出来解决,凭什么还要把钱放在这里? 这些资金一旦离开,就再也不会回来。 过去 Aave 经历过很多治理危机,社区里持有不同意见的人很多,分歧从来没断过。但今天不是争论治理哲学的时候。回望 DeFi Summer 的繁荣,回望我们共同构建的这个去中心化金融世界——我们走到今天不容易。DeFi 的未来不应该毁在一次沉默里。 这不是 Aave 一家的事。Spark、MakerDAO、所有以太坊上的 DeFi 协议都应该参与协调。信任崩塌不分协议,如果这次处理不好,整个 DeFi 的 TVL 会被重新定价,受伤的是所有人。 时间极其宝贵。 Aave 完全可以先承诺兜底,再花时间协调具体方案,这样就能止住挤兑。如果项目方继续沉默,@VitalikButerin 应该出面协调——不需要掏钱,一句「这件事一定会被妥善解决」就够了。 每多沉默一个小时,就有更多资金永久流失。 呼吁 @StaniKulechov @VitalikButerin @AaveDAO @KelpDAO @LayerZero_Core @RuneKek 尽快公开沟通,给市场一个明确信号。 沉默,是最差的选项。

截至目前为止,AAVE已经撤资达到66亿美元,不止主网,多个L2和EVM网络上部署的AAVE借贷池的USDT和USDC均被挤兑一空,存借利率均飙升15%以上。 水友们都在纳闷这样下去AAVE不是自己砸自己招牌呢?应该马上解决啊,又不是赔不起。 主任揣测Aave 尴尬在于不能喊兜底,喊了跟另外两家L0和KelpDAO 就没法谈判如何分摊用户损失了。要是AAVE自家问题, Stani早都喊兜底安抚用户劝阻用户疯狂提现的恶性循环了。 但迟迟不喊兜底又持续被用户挤兑,Defi生态进一步瓦解。要主任说,这时候就应该看V神居中协调了,平常以太神教大旗挥舞,这时候不能再做缩头乌龟了,要肩负起领袖的责任来!

@forgivenever aave的稳定币利率飙升到15%不是太高了 反而是太低了 不足以激励外在用户铤而走险提供稳定币流动性 这里的原因是因为aave在去年调整了slope2的利率曲线 强行压低

KelperDAO因为在L0的DVN验证人只有1/1被攻破,导致以太坊主网L0桥上被盗出约2.8亿美金的rseth,在没有流动性跑路的情况下,黑客将rseth存入aave, compound等借贷协议,借走真金白银weth,导致这些协议出现资金窟窿。 目前AAVE预估窟窿在1亿美金以上,安全基金(Umbrella)只有5600万美金不足以100%覆盖。目前AAVE ETH和Arbitrum的ETH利用率都达到了100%,无法提出任何ETH资产。 目前USDT USDC等主流资产仍然有流动性能够提出,但考虑到协议有资金窟窿,如果用户都提出资金挤兑的话,最后总会有一部分钱出不来。 如果事情得不到官方处理,ETH存款用户通过借出其它主流资产先提走一部分资产。在这个博弈下,有其它资产存款的用户能跑先跑,目前估计很多亚洲用户还没反应过来,随后就会参与到对aave的挤兑行动中。 官方通过增发AAVE拍卖卖币解决资金窟窿也许是一个比较实际的解决方案参考当年MakerDAO的例子。 这次黑客事件对Defi协议安全性信心的打击是非常严重的,直接触及了整个领域最核心的基础设施,主任非常痛心,不知道又要多久才能恢复…

Sparklend在2026年1月开始下架 $rsETH 风控和避免抵押物的潜在风险一直是团队的最高优先级 无论是 $USR $xUSD 还是 $rsETH 或是预言机问题,对Sparklend的安全性都没有任何影响,团队风控一直在线
timzz@timzz_sleep

重大更新: 根据借贷市场的需求和资产风控模型,Sparklend 将逐步移除移除对 [Gnosis Market] 市场的支持,以及对 [$ezETH],[$rsETH],[$tBTC] 作为抵押物的支持, 阶段1设置具体如下: 1)[Gnosis Market] - 不再支持新借贷仓位的建立 - Reserve factor 设置成为50% 2)[$ezETH] - 不再支持 $ezETH 作为抵押物借贷仓位的建立 3)[$rsETH] - 不再支持 $rsETH 作为抵押物借贷仓位的建立 4)[$tBTC] - 不再支持 $tBTC 作为抵押物借贷仓位的建立 - Reserve factor 设置成为99% 以上资产的相关情况,以及目前在Sparklend的利用率如下图1,详细数据可以参考:spark.blockanalitica.com/v1/ethereum/ma… 调整之后,Sparklend支持的合格抵押物为:[$ETH],[$wstETH],[$weETH], [$rETH],[$cbBTC],[$LBTC],详情请参考图2. 未来 @sparkdotfi 将会继续积极支持蓝筹资产,并根据风险模型和需求进行相应调整。

Spark @sparkdotfi 在风险端和流动性端都投入了大量的精力: 风险端: 使用冗余/聚合预言机,并引入机制设计(如脱锚时自动冻结借贷);对抵押资产进行深度基本面研究,通过限额和自动化上限管理限制风险。 流动性端: 专注于交付高流动性的储蓄产品。以 spUSDT 为例,其 8.85 亿的规模中维持着 7 亿的随时提取能力(80% 流动性比率),远超其他链上市场。 /* @sparkdotfi has placed significant effort into both risk management and liquidity sides, mitigating fundamental risks and facilitating onchain repo's key liquidity advantages with respect to risk- in sparklend, we use redundant/aggregated price feeds across multiple providers to mitigate oracle risks, and are continuously introducing mechanism design solutions to alleviate corner cases (eg. automatically freezing borrowing when a pegged asset trades below peg). Additionally, we put significant focus into fundamental research on collateral assets, with rate limits and automated cap management helping limit exposure to issuer failures with respect to liquidity/utility- Spark is laser focused on delivering high liquidity savings products that meet the needs of sophisticated crypto market participants.
monetsupply.eth@MonetSupply

some great risk discourse from @LucaProsperi and @adcv_ Luca reaches the conclusion that defi lenders are significantly underpricing risk vs SOFR, while Adrian counters that defi prime repo markets have very little default risk in practice generally find myself aligned with Adrian, but with a few caveats: (1) risk for prime repo is mostly driven by fundamental rather than market risk, and (2) prime repo provides idiosyncratic advantages that can explain divergence from SOFR/risk free rate benchmarks --- first- the bulk of the risk of onchain prime repo is not from market price jump risk, but rather from technical and counterparty risks embedded in the underlying collateral assets and oracle mechanisms most blue-chip collateral in ethereum defi is either tokenized bitcoin (WBTC, cbBTC) or liquid staking tokens (wstETH, weETH). these collateral issuers have long successful track records, but they are still subject to various fundamental risks including custody/key management, smart contract integrity, business continuity/uptime, etc. additionally, repo markets depend on data integrity, smart contract security, and key management of oracle providers. probability of default/incidents across these dependencies is expected to be very low, but the potential losses incurred in a failure case can be significant (up to 100% of the exposure) looking at the most recent loss events in defi (resolv and drift), we see that they were driven by fundamental risk factors rather than market risk. as a defi lender, the primary driver of risk is these fundamental factors rather than jump risk. --- second- onchain lending has additional benefits that can explain low or even negative spreads vs risk free rates like SOFR fundamentally, i think it makes sense to assume that (most, large scale/sophisticated) market participants are prima facie rational; if they are accepting defi lending risk with yields at or below SOFR, there is probably a reasonable explanation my mental models for this are liquidity premia or convenience yield liquidity premium is the excess return that investors demand to hold assets that cannot be quickly converted to cash at low cost. for tradfi investors, prime MMFs, tbills, and other SOFR benchmarked cash equivalent assets are this asset class and we wouldnt expect them to accept a yield below this in any circumstance. but for cryptonative investors or cryptoasset service providers (think whales, hedgefunds, exchanges), the key measure of liquidity is not the speed+cost to receive cash in a bank account, but rather the speed/cost/slippage to meet their business liquidity needs, which are typically onchain/within the crypto ecosystem. taking a directional hedge-fund as an example, if they face even a 1 hour delay between the time they request redemption of a MMF and when they receive wire transfer into their exchange account, they could easily miss a 5-10% move in a volatile asset, wiping out years of "excess risk adjusted return" they might earn with tradfi SOFR linked instruments over onchain repo convenience yield, the implied return on holding inventories, is another way to look at the same benefit. if onchain actors can expect to derive meaningful benefits from having their assets closer at hand in onchain repo markets, even if the benefit is only realized infrequently, then it can be entirely rational for them to accept risk adjusted returns below SOFR on prime repo opportunities --- @sparkdotfi has placed significant effort into both elements above, mitigating fundamental risks and facilitating onchain repo's key liquidity advantages with respect to risk- in sparklend, we use redundant/aggregated price feeds across multiple providers to mitigate oracle risks, and are continuously introducing mechanism design solutions to alleviate corner cases (eg. automatically freezing borrowing when a pegged asset trades below peg). additionally, we put significant focus into fundamental research on collateral assets, with rate limits and automated cap management helping limit exposure to issuer failures with respect to liquidity/utility- Spark is laser focused on delivering high liquidity savings products that meet the needs of sophisticated crypto market participants taking the Spark Savings USDT vault as an example (app.spark.fi/savings/mainne…), we currently maintain over 700 million in available withdrawal capacity against a 885 million total vault size, or roughly 80% liquidity ratio. this far surpasses the typical liquidity available within other onchain lending markets, which already have a significant liquidity advantage for cryptonative entities vs offchain cash equivalents --- to summarize - market risk is an important consideration, but generally represents only a small factor within onchain prime repo - the larger impact on risk is from fundamental factors, which can be mitigated with a diligent approach to counterparty+collateral evaluation and technical/mechanism design solutions - the market is fundamentally (mostly) rational and delivering superior a superior onchain liquidity profile can justify residual risk exposures, even when the spread vs SOFR is low or negative

@felix_fan @MonetSupply @TrustWallet It is not a debate around CeFi or DeFi, but around how we can make the whole industry a low-risk one for retail and institutions. The risk management framework and philosophy behind your protocol matter. Let's build low-risk finance together.
