According to Coinglass data, the Coinbase Bitcoin Premium Index has been positive for 18 consecutive days, currently reported at 0.0336%.The Coinbase Bitcoin Premium Index is used to measure the difference between the Bitcoin price on Coinbase (a mainstream trading platform in the U.S.) and the global market average price. A negative premium typically reflects greater selling pressure in the U.S. market, a decline in investor risk appetite, increased market risk aversion, or capital outflows.

According to official news, Coinbase will launch Fluent (BLEND) spot trading. If liquidity conditions are met and trading is supported, the BLEND-USD trading pair will open later today.

According to market news, after not conducting any outflow transactions in the past week, BlackRock transferred 12,080 ETH, worth approximately $27.94 million, to a Coinbase Prime address through its Ethereum exchange-traded fund ETHA; additionally, it transferred 113.342 BTC, worth $8.81 million, to a Coinbase Prime address through its Bitcoin exchange-traded fund IBIT.

Coinbase Markets has added Virtuals Protocol (VIRTUAL), Pharos (PROS), and KAIO (KAIO) to the listing roadmap. The specific launch time will depend on market-making support and technical readiness, and will be announced separately once conditions are met.

Coinbase Institutional tweeted that its March market cycle survey shows that among institutional investors, 43% believe we are currently in the late bear market; among non-institutional investors (retail), 49% believe we are still in the bear market markdown phase.

Coinbase stated that it is optimizing the rule creation process in its anti-fraud system by integrating machine learning models with a rules engine, achieving more efficient risk management. It also proposed a dual-track strategy of "models responsible for long-term defense, rules responsible for rapid response," and built a unified framework to create a feedback loop between the two: rules are used to capture new types of fraud and train the model in reverse, thereby continuously enhancing overall defense capabilities.In terms of specific optimizations, Coinbase has transformed the previously manual rule creation process into a data-driven and automated recommendation system by restructuring data, automating schema evolution, and introducing notebook-based analytical tools, significantly improving efficiency. Among these improvements, the performance of rule backtesting has increased by more than 10 times, and the overall response time has been reduced from several days to a few hours. Additionally, the new system uses machine learning to recommend parameters, helping to reduce false positive rates while combating fraud and minimizing the impact on normal users. Coinbase indicated that the next step will be to advance event-driven automatic rule generation and explore the "one-click conversion" of efficient rules into model features, further moving towards an automated risk management system.

The crypto lobbying organization Blockchain Association, along with CCI and more than 120 industry institutions including Coinbase, Ripple, Kraken, and Circle, jointly sent a letter to the U.S. Senate Banking Committee urging the acceleration of the review process for the CLARITY Act.Industry representatives stated that the U.S. needs to establish a unified regulatory framework for the digital asset market, clarify regulatory responsibilities, and strengthen investor protection. Relying solely on law enforcement and regulation cannot create a long-term stable environment. Institutions warned that prolonged policy ambiguity will lead to the outflow of capital, talent, and technology, weakening the strategic advantage of the U.S., while also calling for the development of appropriate federal unified regulatory rules for stablecoins, tokenized assets, and decentralized technologies.

Coinbase Chief Legal Officer Paul Grewal stated that the company has moved the lawsuit filed by New York Attorney General Letitia James regarding its prediction market business from state court to federal court, claiming that the case involves disputes at the federal legal level.The lawsuit accuses Coinbase and Gemini's related prediction market products of violating New York state gambling laws by allowing users to participate in trading events such as sports, entertainment, and elections without obtaining a license. Coinbase believes that prediction markets should be uniformly regulated by the Commodity Futures Trading Commission (CFTC) and will continue to advocate for federal regulatory recognition.The case involves the division of regulatory authority between state and federal levels, which may have significant implications for the regulatory framework of prediction market platforms.

According to the official announcement, Coinbase International has launched gold and silver perpetual contract trading.The announcement states that gold and silver perpetual contract trading is available for retail traders and institutions in selected jurisdictions.

According to BeInCrypto, Mastercard has joined the Blockchain Security Standards Committee (BSSC) as a charter-level member, collaborating with members such as Coinbase, Fireblocks, Anchorage Digital, and BitGo to develop a security framework for blockchain networks and tokenized assets.Mastercard will also join a working group focused on security and privacy guidelines, with Claire Le Gal from the security solutions department, responsible for fraud prevention, cyber resilience, disputes, and threat intelligence, representing Mastercard on the BSSC board. The executive director of BSSC stated that Mastercard's payment experience is of significant value in establishing robust blockchain security rules. Mastercard has launched multi-token networks and crypto credential products aimed at embedding trust in blockchain and tokenized infrastructure.

The "Quantum Computing and Blockchain Independent Advisory Committee" established by Coinbase has released its first position paper. The core conclusion of this position paper is that the core infrastructure of Bitcoin is fundamentally secure. Quantum computing does not pose a substantial threat to Bitcoin mining, hash functions, and the historical records of the blockchain. The real vulnerability lies at the wallet level, and Ethereum has laid out a clear roadmap to address this issue in the near future.Previously, Coinbase announced the establishment of the Quantum Computing and Blockchain Independent Advisory Committee in January this year, with committee members including researchers from Stanford University, the University of Texas at Austin, and the Ethereum Foundation.

According to CoinDesk, the Bitcoin Coinbase premium index has been positive for 14 consecutive days since April 9, marking the longest bullish record since BTC reached its historical high of over $126,000 in 2025.As the preferred exchange for institutional investors in the United States, Coinbase's sustained positive premium indicates that U.S. institutions such as corporate treasuries, hedge funds, and ETFs are actively buying BTC.

According to Decrypt, Coinbase's Quantum Computing and Blockchain Independent Advisory Committee released a report on Tuesday stating that proof-of-stake (PoS) blockchains may face a greater risk of exposure to future quantum computing attacks, as the cryptography relied upon by the validator signatures that protect these networks could ultimately be cracked by sufficiently powerful quantum computers. The report points out that PoS networks like Ethereum and Solana rely on cryptographic signatures—Ethereum validators use BLS signatures, while Solana validators and users use Ed25519 signatures—to help the network reach consensus on blocks and maintain consensus.The advisory committee stated, "PoS chains have exposure risks in the signature schemes used by validators to protect the network, which means that the challenges faced by PoS are not just about upgrading wallets; parts of the core consensus mechanism itself may need to be redesigned." The report mentioned recent work by Ethereum developers, including a proposal by co-founder Vitalik Buterin in February to replace BLS validator signatures, KZG commitments, and ECDSA wallet signatures with quantum-resistant alternatives.The committee also listed the digital signatures used in cryptocurrency wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins belong to the category where the public keys are already visible on-chain. The report stated that the current cryptocurrency system remains secure, as quantum computers capable of breaking modern cryptographic signatures do not yet exist.
