According to an official announcement by Volo, a security vulnerability occurred today on the Sui network involving Volo—a BTCFi and LST protocol—resulting in the theft of approximately $3.5 million in assets (including WBTC, XAUm, and USDC) from three specific vaults. Immediately after the incident, the team notified the Sui Foundation and ecosystem partners and froze all vaults to prevent further losses. Volo stated that the vulnerability affected only these three vaults; the remaining vaults are not exposed to the same attack vector, and the other ~$28 million in TVL remains secure. The official announcement emphasized that Volo will bear the loss entirely and will not pass it on to users. A comprehensive post-mortem report and remediation plan will be released upon completion of the investigation.

Odaily News Etherealize has released its latest report, adjusting the long-term price expectation for Ethereum (ETH) to $250,000.This prediction is based on a core assumption: if ETH can capture a "monetary premium" similar to gold and Bitcoin, securing a place in the approximately $31 trillion store-of-value market, its price could reach this level.The report argues that ETH possesses unique historical attributes, serving not only as a store of value but also as a "yield-generating asset," distinguishing it from traditional asset forms.
Odaily News Kevin Warsh stated during a Senate hearing that digital assets "have become part of the U.S. financial system" and supports their inclusion into the financial system to provide investors with more opportunities and protection.This statement is seen as a signal of a generally more open policy towards the cryptocurrency industry should he become the Federal Reserve Chair. Warsh has previously referred to Bitcoin as an "important asset that aids in policy-making."However, Elizabeth Warren expressed concerns during the hearing, mentioning potential risks in the crypto space such as "sock puppet" accounts, emphasizing the need for enhanced regulation and prevention of abuse.

Odaily News The PACE Act, proposed by bipartisan U.S. lawmakers, aims to allow compliant non-bank payment institutions direct access to the Federal Reserve's payment system, garnering support from the cryptocurrency industry.The bill would establish a federal framework overseen by the Office of the Comptroller of the Currency, providing a unified registration pathway for payment companies and requiring them to maintain 1:1 reserves while meeting risk control and record-keeping compliance requirements. Eligible institutions would gain access to core payment networks such as Fedwire, FedNow, and FedACH.The legislative goal is to reduce payment costs, improve speed and reliability, making the transfer experience as simple as "sending a text message." Industry perspectives suggest this move could potentially break the traditional banking monopoly on underlying payment infrastructure, opening a crucial gateway for stablecoins and crypto payment companies, further promoting openness and competition within the financial system.

The report notes that the proposal has garnered support from fintech and cryptocurrency groups, with the goal of making the payment system faster, lower-cost, and more competitive.
Odaily News A 50-page report commissioned by Coinbase indicates that although current quantum computers are not yet capable of cracking the encryption technologies of networks like Bitcoin and Ethereum, fault-tolerant large-scale quantum computers will eventually be built, and the crypto industry must begin preparations now. The report was authored by an independent advisory committee, including cryptographers and scholars such as Dan Boneh from Stanford University, Justin Drake from the Ethereum Foundation, and Sreeram Kannan from Eigen Labs.The report states that estimates for the time it would take quantum computers to break current encryption standards range from several years to over a decade. The U.S. National Institute of Standards and Technology recommends migrating to post-quantum cryptography by 2035, but the report suggests this timeline may be optimistic. Post-quantum cryptography already exists and is undergoing standardization, but post-quantum digital signatures can be tens to hundreds of times larger than existing signatures, potentially increasing block sizes by up to 38 times and introducing challenges such as wallet migration. The Ethereum Foundation has proposed a post-quantum digital signature scheme, and projects like Solana are also experimenting with post-quantum wallet designs. The report recommends adopting flexible transition strategies, such as hybrid systems, to prepare for future upgrades without compromising current security.
According to an official announcement, Coinbase will list Sign (SIGN) spot trading on April 21. The SIGN-USD trading pair will go live later that day, once liquidity conditions are met, in regions where such trading is supported.
Coinbase’s Quantum Computing and Blockchain Independent Advisory Committee released its first position paper, stating that sufficiently powerful quantum computers could one day break the cryptographic mechanisms used by mainstream blockchains to protect digital assets—but such devices do not yet exist, and crypto assets remain secure for now. The industry should begin preparing for quantum-resistant upgrades immediately. The paper notes that Bitcoin mining, hash functions, and on-chain historical records currently face no material risk; the primary vulnerability lies at the wallet layer—in digital signatures. Ethereum has already proposed a relatively clear migration roadmap, while Solana, Algorand, and Aptos have either begun offering or are planning quantum-resistant solutions.
