The advisory committee of cryptographic experts led by Coinbase has released a report stating that Bitcoin should immediately begin preparing for potential quantum computing attacks. However, the committee did not take a clear stance on whether to freeze the millions of Bitcoins that could potentially be stolen by quantum computing in the future.It is reported that the committee members include several leading experts, such as Ethereum Foundation researcher Justin Drake, who believe that the current focus of the debate is not on how to introduce quantum-resistant signature technology, but rather on how to handle the Bitcoins that have not been migrated for a long time. One viewpoint calls for setting a deadline, after which the existing ECDSA and Schnorr signature schemes for Bitcoin will cease to be supported, and un-migrated assets will be frozen to prevent future quantum attackers from acquiring large amounts of BTC and impacting the market. Another viewpoint argues that this amounts to asset confiscation, contradicting Bitcoin's core principles of "immutability and user complete control of assets," and could set a precedent for freezing assets in the future due to regulatory pressure.The Coinbase advisory committee pointed out that the aforementioned proposals are not mutually exclusive and can be combined, but it refused to take a position on the issue of "whether to freeze legacy BTC," believing that the final decision should be governed by the Bitcoin community. At the same time, it emphasized two points: first, the technical development of quantum-resistant signature migration should be initiated immediately and should not wait for the governance debate to conclude; second, it is necessary to clearly communicate risk information to users to avoid long-term uncertainty affecting the Bitcoin ecosystem.

According to Coinglass data, the Coinbase Bitcoin premium index has been positive for 2 consecutive days, currently reported at 0.208%. The buying sentiment in the U.S. market has begun to warm up, after being in negative premium for 24 consecutive days.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. This index is an important indicator for observing the flow of funds in the U.S. market, the enthusiasm of institutional investors, and changes in market sentiment. A positive premium indicates that the Coinbase price is higher than the global average price, which usually means: strong buying in the U.S. market, active entry of institutional or compliant funds, ample dollar liquidity, and an optimistic investment sentiment. A negative premium indicates that the Coinbase price is lower than the global average price, which typically reflects: significant selling pressure in the U.S. market, decreased risk appetite among investors, rising market risk aversion, or capital outflow.

Coinbase announced on Wednesday the launch of two on-chain USDC lending vaults on Morpho, with Steakhouse Financial serving as the risk curator, providing users with lending options at different risk levels for the first time. The Prime vault adopts a conservative strategy, using blue-chip crypto assets like BTC and ETH as collateral, with yields ranging from approximately 3.5% to 4%. The High Yield vault accepts a broader basket of collateral, including assets issued by Ethena, with an annualized yield of about 8.79% supported by Ethena's government bond-backed stablecoin USDtb.Morpho provides a non-custodial lending infrastructure, with Steakhouse Financial managing approximately $2.03 billion in Morpho vault TVL, leading the second place by about $1 billion. Coinbase's collaboration with Ethena predates the launch of these vaults, as Coinbase Ventures purchased ENA tokens on the open market in June as part of a broader distribution agreement.

Coinbase CEO Brian Armstrong tweeted, "For years, cryptocurrency trading has been shifting overseas due to the lack of clear regulatory rules in the U.S., and while perpetual contracts are favored by traders, they are banned in the U.S. Frankly, about half of the perpetual contract trading volume comes from U.S. users who use offshore products via VPNs, and KYC checks are lax. Other companies have set up offshore entities to find ways to evade regulation. After dozens of trips to Washington, D.C., and numerous communications from our policy team, we finally received approval to allow U.S. users to access true global perpetual contracts."Previously, the CFTC's Market Participants Division issued a clarification letter and a no-action letter to registered futures commission merchant Coinbase Financial Markets (CFM), allowing it to offer cryptocurrency options and perpetual contracts listed on the affiliated offshore exchange Deribit FZE to U.S. users. The letter confirmed that the aforementioned perpetual contracts can be classified as foreign futures under CFTC Regulation 30.1.Additionally, under specific conditions, the CFTC will not recommend enforcement action regarding CFM transferring digital commodities held by customers and paying stablecoins to its offshore brokerage affiliates for margin purposes, and that affiliate may exercise reuse rights over the aforementioned customer assets.

According to Decrypt, the Coinbase Quantum Advisory Board released a report calling for blockchain developers to immediately begin preparations for quantum migration, warning that unresolved issues with abandoned and vulnerable tokens could become one of the biggest challenges for Bitcoin.The report estimates that approximately 7 million Bitcoins are vulnerable to future quantum attacks due to public key exposure and address reuse. Although there are currently no quantum computers capable of breaking blockchain encryption, the likelihood of relevant quantum computers emerging as early as 2030 is high.The report proposes three handling options for tokens that have not migrated to quantum-safe addresses: permanently freeze or destroy them after a set deadline; take no action and let users decide; or adopt a compromise measure, such as limiting the number of vulnerable tokens that can be moved per block, or allowing users to pre-commit to migration.The Ethereum Foundation has formed a team to coordinate the post-quantum security transition, and Vitalik Buterin developed a quantum upgrade roadmap in February. The Stellar Development Foundation announced a roadmap for user migration to quantum-safe encryption on Tuesday.

Ethena's official announcement states that the first product launched in collaboration with Coinbase is now officially online, which is the stablecoin yield pool introduced by SteakhouseFi.
