不想说什么了,祝各位安好。

最近多起 @Ledger 硬件钱包被改装的案例闹得人心惶惶。 我一直坚信硬件钱包的安全,不该靠厂商宣传来证明。 开源不等于安全,但硬件设计和固件代码公开,潜在问题才更有可能被第三方提前发现。用户也能对照公开的设计,检查手里的设备有没有被改动。 闭源只能选择相信,公开至少可以让我们有机会验证。

2026年还能看到这种漏洞,以及Balancer...
🚨SlowMist TI Alert🚨 💸 @Balancer Loss: ~234k USD 🔍 Root Cause: Balancer V1 BPool `joinswapPoolAmountOut` lets caller specify BPT output while `calcSingleInGivenPoolOut` reverse-computes input via 18-decimal fixed-point math. After attacker compressed WBTC reserves to dust via public swaps, the computed input rounded down to 1 satoshi WBTC yet full BPT was minted. Missing: minimum effective input, minimum pool balance, and relative-error validation; `MIN_BALANCE` only enforced in `bind/rebind`. 📌 Attacker: 0x338c7ec9befbb451d66fd8a468c32184f5689a41 📌 Attack Contract: 0x9caa8d0e44b22f50057d2f4ce0d1446529e11be3 📌 Vulnerable Contract: 0x2257aaac34bcb27900291f7b84ee2565a6cbac57 Impact: Nested flash loans (Spark/Aave, Morpho, Uniswap V3) funded WBTC reserve compression; 4,408.8 BPT minted at 1-satoshi WBTC per join, then proportionally exited to drain DPI, USDC, WETH, WBTC from the pool.

也许是下一个Altura,目前NUSD的市场价格波动尚且不大,建议立即降低暴露敞口,避免潜在的风险。
Neutrl has temporarily paused minting, redemptions, and other protocol functions following circumstances affecting protocol reserves. These measures have been taken in the interest of our users, after advice from legal counsel, to preserve an orderly process while the impact is assessed. Users will be provided with a clear and orderly process in due course. Further information on timing, and next steps will be shared as soon as available.

做了一个币安最近RLUSD活动的看板,看起来APR是越来越低了... rlusd.leter.app/ 建议以悲观值作为参考基准。

#SecondFi 钱包的事件相信大家已经听说,然而很有趣的是这部分的错误实现是在新版本的钱包中被引入的,问题也并不在于初始的私钥生成部分。 在新版本中,96-byte xprv 被传入普通的 PrivateKey signer,只取前 32-byte kL,丢掉 kR,因此变成使用可公开运算的 H(M) 生成 nonce,由于链上签名满足 S=r+H(R,A,M)·kL mod L,R/S/A/M 都是公开可见的,r 能够由 M 计算得出,所以只要使用新钱包通过受影响路径发送/签署过任意一笔交易就能解出 kL,而拥有 kL 就相当于拥有对应私钥的签名能力。 整个错误都是额外引入的,让人不禁怀疑团队内部的交接状态和整体工程流程。为什么这种重大问题会在一个品牌迭代的过程中被引入?我想也许这个问题会很难有一个合适的答案。

甚至项目方三天前刚刚发推特在Curve流动性池新增了LP激励。
Curve bribes are back. 35M $SPELL → MIM-3Pool 35M $SPELL → MIM-2Pool 70M $SPELL total deployed to strengthen MIM liquidity across Curve. More to come. 🧙‍♂️

$MIM 也已经脱锚,成为继AVLT和mUSD后下一个倒下的收益性衍生美元代币。 Abracadabra 协议历经 Luna 时代一路运营到现在,但是还是终究逃不过结局。

Altura宣布关闭,又一个“零知识储备证明”。
Dear Users, Over the past 24 hours, we have experienced an unprecedented level of withdrawal requests and have successfully processed more than 8.5 million USDT in instant redemptions. Given the sustained withdrawal demand and current market sentiment, we have made the difficult decision to begin an orderly wind-down of the Altura vault. Our priority remains the protection of user capital and ensuring all redemptions are completed in a fair, transparent, and efficient manner. To facilitate this process, we have notified all counterparties and partners of our decision and have started unwinding positions across the portfolio. These positions include allocations held on exchanges, private credit opportunities, and real-world asset strategies. While some positions can be redeemed immediately, others require standard settlement and redemption periods, and we are working closely with all counterparties to accelerate the process wherever possible. We want to reassure all users that the wind-down is being conducted in a structured manner and that capital is being returned as underlying positions are redeemed. Despite it being a weekend, our team has worked around the clock to process withdrawal requests and maintain continuous communication with partners and users. I am incredibly proud of the effort and commitment demonstrated by everyone involved during this period. Personally, I am deeply disappointed by how quickly misinformation and speculation can spread within the industry. Altura has always operated with transparency and integrity, and it is unfortunate to see unfounded narratives contribute to market fear and withdrawal pressure. Nevertheless, our focus remains unchanged: executing an orderly wind-down and returning capital to users as efficiently as possible. We will continue providing regular updates as redemptions progress and additional liquidity becomes available. Thank you for your trust and support throughout this process. Ranveer Arora CEO, Altura

零知识储备证明:你对存款状态零知识,他们对偿付义务零知识,跑路后大家对资金去向也零知识。名副其实。
Accountable has terminated its service agreement with MainStreet, effective immediately. MainStreet was unable to meet our verification standards. We recognize that markets relied on this feed and are working closely with partners across the ecosystem as the situation evolves. We will continue to hold this standard without exception.

经过约7个月,@ether_fi 已对此前被盗刷的$497.84进行了全额退款。感谢 @MikeSilagadze 介入并且跟进了我的事件。 虽然是一个迟到的结果,但是终究是得到了解决。 同样希望其他受影响的用户也能得到妥善解决。
2025年10月24日,我的 @ether_fi Cash卡遭到盗刷,共计约$497.84美元,我当天就冻结卡片随即联系客服发起争议。 @MikeSilagadze 在这篇帖子下公开承诺所有受盗刷影响的用户都将获得退款。 七个月过去了:没有退款、没有官方声称已发送的私信、有的只是一套重复粘贴的推诿说辞。 而其他用户的遭遇也与我基本一致。 以下是这几个月里实际发生的事: → 先后经手五位客服(Luna、Zucher、Zahar、Solomon、Leo),每次换人都要重新解释案情,毫无实质进展 → Visa 以「3DS 已验证」为由拒绝争议——但我从未收到任何验证请求,多次索要验证日志,至今无果 → 3 月收到的「调查结果」与最初的拒绝通知几乎一字不差,明显是模板复制 → 5 月 11 日客服明确 acknowledge 了我设定的 5 月 21 日截止日,截止日过去后直接消失 与此同时,@ether_fi 官方也声称已向受影响用户发送了私信。我从未收到任何私信。 更讽刺的是:就在同一天,@MikeSilagadze 亲自在 @wisdom_yang 的帖子下联系了另一位受害者并协助加急退款。我当时就在那条帖子的评论区里询问,留言至今还在。 同样的欺诈,同样的承诺,不同的待遇。 其他在 2025 年第四季度遭到盗刷的用户——你们的问题解决了吗?
