Zilliqa stated that there is a serious random number generation vulnerability in the Zilliqa Ledger application, affecting the Schnorr signatures of native non-EVM Zilliqa transactions. Attackers can recover the signer's private key from the biased temporary random numbers using only publicly available on-chain data.Any account that has signed and broadcasted about 5 or more native transactions through the Zilliqa Ledger application should be considered compromised. Since the related signatures are permanently recorded on the chain, subsequent updates to the application cannot eliminate the risk, and the affected private keys must be deactivated. EVM transactions and development tools such as zilliqa-js, gozilliqa-sdk, and pyzil are not affected.The vulnerability arises from the application selecting the wrong 32 bytes when copying the random number, retaining 8 bytes of zero padding and losing 8 bytes of entropy, resulting in each random number having a maximum of 64 bits fixed to zero. Attackers can use 5 or more affected signatures to recover the private key within seconds using ordinary hardware. Zilliqa observed suspected active exploitation on July 19 and confirmed the root cause on July 21.Zilliqa has suspended native transactions to prevent further loss of funds and is preparing a revised application with Ledger. However, the revised version cannot protect the exposed keys, and affected users should not transfer assets on their own but wait for the official announcement of a coordinated disposal plan.

According to Jinshi reports, Capital Economics strategist Thomas Mathews stated in a report that gold still holds value as a hedge against a sharp decline in the stock market. Recently, gold's performance has resembled that of a "risk" asset, with its price volatility comparable to that of the benchmark S&P 500 index.Although gold performed poorly during the Middle East conflict, its connection with real bond yields remains intact, and a decline in real yields is expected to boost gold.

According to reports, Google DeepMind co-founder Demis Hassabis recently predicted that artificial general intelligence (AGI) could be achieved in just a few years, with its transformative impact reaching ten times that of the Industrial Revolution, and its development speed accelerating tenfold. He pointed out that as the potential risks of cutting-edge models in areas such as cybersecurity, nuclear energy, and biology become increasingly prominent, the industry urgently needs to establish robust security protections for future AI systems that possess autonomy and self-improvement capabilities.To balance technological innovation and security risks, Hassabis called for the United States to take the lead in establishing a "Frontier AI Standards Agency" similar to the Financial Industry Regulatory Authority (FINRA). This agency is proposed to operate under a public-private partnership or self-regulatory organization model, managed by independent technical experts and representatives from the open-source community, primarily funded through industry contributions. Its core function is to develop dynamic scientific assessment protocols, initially requiring frontier laboratories to voluntarily submit for review 30 days prior to the release of models, with plans to eventually transition to mandatory market entry testing, while non-frontier models from startups or academic institutions would be exempt. This framework aims to address unknown crises through a technology-driven review mechanism and to promote a global consensus on AI risk management within the international community.

Ledger announced the expansion of support for Celo, having integrated Celo's CIP-64 fee abstraction feature into Ledger Live. After the upgrade, users can pay on-chain transaction gas fees using 18 types of Celo native assets, without needing to use the native token CELO exclusively.The assets that can be used to pay gas include USDT, USDC, USDm, EURm, GBPm, JPYm, CADm, AUDm, CHFm, BRLm, NGNm, PHPm, COPm, KESm, ZARm, XOFm, GHSm, and WETH. CIP-64 is a core mechanism introduced by Celo in the July 2023 Gingerbread hard fork, allowing transaction fees to be paid directly with approved ERC-20 tokens.According to official disclosures, nearly half of the transactions on the Celo chain are currently settled with US dollar stablecoins instead of CELO for transaction fees. Ledger had previously supported the sending, receiving, and exchanging of CELO and Celo native stablecoins in Ledger Live as of December 2025.

Participating banks include ANZ, BNP Paribas, BNY Mellon, Citibank, DBS Bank, First Abu Dhabi Bank, FirstRand Bank, HSBC, Itaú Unibanco, Lloyds Bank, Mashreq Bank, MUFG, OCBC Bank, Standard Chartered, UBS Group, UOB, and Wells Fargo.

According to CoinDesk, the new version of the XRP Ledger server software v3.2.0 has been launched, aiming to reduce operational costs, enhance stability, and increase appeal to institutional users. Currently, about 43% of the approximately 833 active nodes are running the new version, while 51% are still using the old version v3.1.3. However, about 89% of the 35 validators in the default UNL have upgraded, reaching the required 80% threshold for activation.The security amendment fixCleanup3_2_0 associated with the software upgrade is still under independent voting, covering fixes and improvements for single-asset vaults, permissioned DEX, multi-purpose tokens, and lending protocols, with current support far below the software adoption rate. Ripple has voted in favor of this amendment, and validators that do not upgrade before the amendment is activated may face the risk of being cut off from the Ledger.

According to The Block, influenced by the maturation of the crypto market and the rapid development of emerging technologies, several leading crypto venture capital firms are shifting their investment focus from the pure crypto sector to a broader "frontier technology" track, involving AI, robotics, fintech, and biotechnology.It is reported that Framework Ventures and Haun Ventures have recently raised $400 million and $1 billion funds respectively to support cross-domain layouts; Paradigm is planning to raise up to $1.5 billion for a frontier technology fund; and the former Binance incubator YZi Labs has also ventured into the fields of AI and biotechnology.Industry investors analyze that the core reasons for this strategic shift are the demand for capital deployment brought about by the expansion of fund sizes, the decrease in high-quality pure crypto projects, and the increasing integration of adjacent technologies such as blockchain and AI. Some venture capitalists predict that as cryptocurrencies gradually integrate into a broader technology ecosystem, the exclusive label of "crypto VC" may gradually fade, and the market will ultimately differentiate into large multi-strategy investment funds and a few vertical investors focused on digital assets. However, some institutions like a16z Crypto and Dragonfly still insist on deepening their investment strategies in the pure crypto sector.

According to Fortune, the crypto venture capital firm Framework Ventures announced the completion of its fourth fundraise, totaling $400 million. The investors include endowment funds from Ivy League schools, sovereign wealth funds, and non-profit organizations, though the specific names have not been disclosed. Framework co-founders Vance Spencer and Michael Anderson stated that the new fund will invest in the field of "cutting-edge technology," which includes not only crypto but also areas such as AI, robotics, and energy. Currently, about half of the funds from the fourth fund have been deployed.Framework Ventures was established in 2019 and initially focused on investments in the DeFi sector, participating in early rounds of leading protocols such as Aave and Chainlink. Previously, it completed fundraises of $100 million and $400 million for its second and third funds in 2021 and 2022, respectively.

The second round of the World Cup group stage schedule is halfway through, with some teams having already secured or are close to securing qualification, while several teams still need to determine their fate in the third round. In today's matches, Spain defeated Saudi Arabia 4-0, Belgium drew 0-0 with Iran, Uruguay drew 2-2 with Cape Verde, and New Zealand lost 1-3 to Egypt. As the group stage enters a critical phase, situations where the pre-match high probability directions do not materialize are still frequently occurring, further amplifying the risk of unilateral positions for prediction market users.Base's native leverage prediction market OmenX officially launched the World Cup Hedge to Earn airdrop event today, currently distributing hedge positions to all Polymarket users with positions. After users connect their Polymarket wallets, OmenX will identify their eligible positions; if there are relevant events on the platform, corresponding hedge positions will be issued; if there are no matching relevant events, recommended position airdrops will be provided to help users experience hedging and position management.OmenX stated that Hedge to Earn aims to help prediction market users transition from "unilateral prediction" to "position management." For high-volatility events like the World Cup, users can obtain hedging rewards through OmenX, adding a layer of risk buffer to their existing Polymarket positions.
