Major stock indices were up today on continued U.S. trade talks with China, after Google dragged Nasdaq down with it. Positive sentiment prevailed in the broader markets, though the tech sector saw some turbulence. On Wednesday, May 7, the Dow Jones rose 377 points, or 0.92%, while the S&P 500 gained 0.42%. The Nasdaq, however, hovered just above the opening level, up 0.07%, after briefly diving 200 points earlier in the day. The tech-heavy index fell sharply from a high of 17,793 to a low of 17,600 in under an hour, largely due to pressure on major tech stocks. Notably, Google was one of the biggest losers, dropping 8.11% following reports that Apple plans to shift its Safari browser’s focus to AI-powered engines.

Apple’s stock was also down 1.46%. Importantly, Google currently pays Apple $20 billion annually to remain the default search engine on Apple devices. Renewed trade talks boost markets Despite tech stocks tumbling, markets were up on news of renewed trade talks between the U.S. and China. Notably, reports surfaced that U.S. officials were meeting with Chinese representatives to resolve the tariff crisis. Talks are set to take place this week on the unprecedented 145% U.S. tariff rate on all Chinese goods, and the retaliatory 125% Chinese tariffs. While these talks are encouraging, it is likely that negotiations are going to last at least several months.

Sygnum Bank is now allowing clients to use staked SOL as collateral for multi-currency loans, as institutional demand drives a doubling in its crypto lending volume. Swiss digital crypto-friendly bank Sygnum has added staked Solana (SOL) to its portfolio of tokens eligible as collateral for Lombard loans, allowing clients to access fiat liquidity while continuing to earn staking rewards. In a Thursday blog announcement, the Swiss bank said the new feature applies to loans in Swiss francs, euros, Singapore dollars, and U.S. dollars. The new update allows Sygnum clients to unlock liquidity from their staked Solana holdings while continuing to earn staking rewards, creating “dual-income potential from a single crypto asset,” the bank said. Sygnum also noted that Lombard loans that pledge staked SOL as collateral are “low-cost because the generated staking rewards are used to cover the majority of the fees.” You might also like:Swiss crypto bank Sygnum adds Deribit into off-exchange custody platform The move comes as Sygnum’s lending business has seen significant growth as its loan volume doubled over the past 12 months, the press release reads. The latest addition expands Sygnum’s Lombard loan collateral pool, which already includes Bitcoin (BTC), Ethereum (ETH), unstaked SOL, Polkadot (POL), Ripple’s XRP (XRP) and other altcoins. Benedikt Koedel, head of credit & lending at Sygnum Bank, said the addition of staked Solana as collateral aims to meet a “key client need to optimise yield while maintaining liquidity.” In November 2024, a Sygnum survey of over 400 high-net-worth investors found growing confidence in crypto’s long-term potential, driven by demand for portfolio diversification and macroeconomic hedging. The report linked this optimism to expected higher returns and a broader “megatrend” fueled by strong interest in the sector. Read more:Swiss crypto bank Sygnum bags $58m, reaches $1b unicorn status

Ethereum Foundation has clarified that the upcoming Pectra upgrade will not include the highly debated EOF changes as those will come with the next upgrade, Fusaka. In his April 28 post on X, Ethereum Foundation Co-executive Director Tomasz K. Stańczak said that the upcoming Pectra upgrade, slated for May 7, does not include EOF, stating: “The Pectra upgrade does not include EOF, nor [is it] intended to include EOF. Everything on Pectra is going as planned for the May 7th release.” EOF, which stands for Object Format, is a major overhaul of Ethereum’s execution engine intended to optimize and modularize the Ethereum Virtual Machine. The EOF proposal has sparked intense debate among Ethereum developers in recent months, with many criticizing it for its unnecessary complexity. Source: @velvetkeyboard Despite this, Ethereum leadership decided to go ahead with implementing Full EOF — but only with the next network upgrade, Fusaka, which is now tentatively slated for Q3/Q4 this year. Tim Beiko, who runs Ethereum’s core protocol meetings, told participants during Thursday’s All Core Developers call, “We can’t choose not to do something just because it’s complex.” You might also like:Vitalik Buterin responds to security concerns over new Pectra upgrade Pectra, the upgrade set for May 7, is aimed at improving Ethereum’s validator UX, making it possible for users to pay transaction fees in USD Coin (USDC) instead of ETH, increasing validator staking limit from, and more. Fusaka, the following upgrade, is more ambitious. Besides restructuring how smart contracts are written and executed through EOF, it aims to make Ethereum network more efficient and scalable. This is meant to improve the performance of Ethereum’s base layer, which has been steadily declining, leading several major players to sharply reduce their Ether holdings. According to Lookonchain, Galaxy Digital recently deposited 65,600 ETH (worth $105.5 million) to Binance and then withdrew 752,240 Solana (SOL), suggesting it sold its ETH to buy SOL. Paradigm has also recently cut its ETH exposure by selling 5,500 ETH ($8.66M) to an institutional brokerage platform Anchorage, according to EmberCN. “While institutional investors initially bought into the ‘ultra-sound money’ narrative, they’re now facing a reality where decreasing protocol revenue and weakening tokenomics create legitimate concerns,” Jayendra Jog, co-founder of Sei Labs, told Cointelegraph.

欧洲央行表示，如果没有更强有力的欧洲保障措施，美国总统唐纳德·特朗普支持加密货币的立场可能引发不稳定。 欧洲央行和欧盟委员会就欧盟新的加密规则是否能够抵御唐纳德·特朗普回归带来的金融风险陷入争议。 根据POLITICO看到的一份政策文件，欧洲央行警告称，特朗普对美国加密货币行业的支持可能引发金融“传染”，并表示加密资产市场监管亟需改革。央行认为，目前的监管对“多方发行”模式（即欧洲和非欧洲稳定币发行机构合作的模式）过于宽松。 欧洲央行行长克里斯蒂娜·拉加德指出，MiCA 必须做出改变，并暗示欧盟委员会和欧盟其他机构“理解”稳定币带来的独特威胁。 您可能还喜欢：Circle 政策主管提倡 MiCA 扩大加密货币监管 尽管如此，委员会还是强烈反驳了这一观点，正如 POLITICO 看到的委员会文件所示，委员会表示，此类全球稳定币带来的风险“似乎被夸大了，在现有法律框架下是可控的”。 一位欧盟官员告诉 POLITICO，欧洲央行的担忧是基于对 MiCA 的“根本性误读”，并补充说，对一对一支持的资产进行传统挤兑的想法是“无稽之谈”。该官员还指责欧洲央行“炒作稳定币的威胁”以赢得对其数字欧元项目的支持，该项目预计将于 10 月启动。 欧洲央行担心，美元支持的稳定币（这类稳定币已占据市场主导地位）的激增，可能会将欧洲资本拉入美国债务，损害欧盟的财政独立性。央行还警告称，欧洲发行方可能被迫赎回欧洲和外国的代币，从而有可能引发储备“挤兑”。 阅读更多：分析人士称，新的 MiCA 制度将促使加密货币公司退出欧盟市场

Conflux 表示，其安全团队已通过 2.5 版网络升级成功修补了 CREATE2 Opcode 漏洞。 Conflux (CFX) 网络于 2025 年 3 月 24 日宣布，在生态系统团队 GraFun 的帮助下检测到的安全漏洞已成功修补。据报道，GraFun 今年 2 月发现了与以太坊 (ETH) 虚拟机相关的 CREATE2 操作码中的严重漏洞。 CREATE2 操作码于 2019 年通过以太坊君士坦丁堡升级引入，是以太坊和以太坊虚拟机兼容网络的一项高级功能。它在智能合约中起着关键作用，特别是在部署可预测性和灵活性方面。Conflux 团队对此进行了详细说明： “在标准以太坊虚拟机中，如果目标地址已经部署了合约，则 CREATE2 操作码将无法部署合约，并返回空地址。但是，Conflux 的先前实现允许 CREATE2 在具有现有合约的地址重新部署合约，将合约状态重置为其初始部署状态。” 你可能还喜欢：以太坊开发人员在 sepolia 上找到 Petra 升级错误的修补程序 据 Conflux 称，该安全问题已在 2025 年 3 月 17 日发布的 Conflux 2.5 版升级后得到解决。该第 1 层平台指出，该漏洞“允许在现有地址上重新部署合约，从而影响 Gnosis Safe”。 Conflux 网络安全团队向用户和生态系统合作伙伴保证，2.5 版本升级已完全解决该缺陷。 Conflux 于 2025 年 3 月 4 日公布了网络升级计划，并要求节点运营商进行相应更新。该平台暂定于 3 月中旬进行硬分叉，时间为 118580000 纪元。 GraFun 因其在安全升级中所发挥的作用而获得了总计 60,000 个 Conflux 代币，其中包括因识别 CREATE2 操作码漏洞而获得的 50,000 个代币基本赏金。该平台还因及时提供报告以帮助防止潜在的漏洞和损失而获得了 10,000 个代币。 Conflux 在公告中表示，所有用户资金都是安全的，并且网络的 EVM 兼容性已增强。 你可能还喜欢：Bitin 被以色列监管机构关闭，并被处以 46 万美元罚款
