Aave CEO Stani tweeted that the latest draft of the market structure bill in the United States has been released. This bill can provide strong legal protection for DeFi developers in the U.S., allowing them to confidently build and maintain decentralized protocols without being forced to bear heavy obligations that are only suitable for centralized models. If the U.S. successfully establishes this framework, other regions around the world will follow.Stani emphasized that regulatory clarity is more important for DeFi than yield. The passage of the Clarity Act is expected to bring significant tailwinds to DeFi, similar to what the Genius Act has done for stablecoins.

At the Consensus 2026 Miami conference, Zcash Open Development Lab CEO Josh Swihart announced that Zcash will launch a quantum recoverable wallet within a month and fully achieve post-quantum status within 12 to 18 months.Additionally, the independent scaling solution aims to achieve Mastercard/Visa-level throughput within a similar timeframe. On the user side, the Electric Coin Company's wallet has enabled cross-chain swaps from assets like BTC, SOL, and USDC to privacy ZEC through the integration of Near Intents, with approximately $600-700 million in funds flowing through this route since its launch. The Near ecosystem's 30-day processing volume is close to $800 million, with Ethereum, Solana, and Zcash being the main chains.Furthermore, the project community is discussing reducing the Zcash block time from 75 seconds to 25 seconds, and the cross-chain bridge with Solana and Hyperliquid has gone live. A voting feature for token holders will also be launched, serving as an opinion layer for the project's existing consensus model. Currently, Zcash's shielded pool accounts for 30% of the circulating supply, reaching an all-time high. Analysts believe that if this ratio continues to grow with rising prices, this round of increase will be driven by real adoption rather than mere speculation.

The Japan Crypto Asset Business Association (JCBA) officially released the "Best Practices for Crypto Asset Staking Operations" guidelines, covering various aspects such as operational requirements, emergency response, information disclosure, compliance management, external auditing, and tax accounting, aiming to enhance the security and transparency of domestic staking services.

According to The Block, Michael Selig, chairman of the Commodity Futures Trading Commission (CFTC), stated that the CFTC is considering establishing rules to solidify its protective stance towards non-custodial software developers. In March of this year, the CFTC issued a no-action letter regarding the cryptocurrency wallet Phantom, indicating that it would not take enforcement action for not being registered as a broker and clarified that eligible self-custody wallet software developers do not need to register as brokers. Selig mentioned that the CFTC is seeking to formally incorporate this stance into rulemaking.Additionally, Selig reiterated that prediction markets fall under the exclusive jurisdiction of the CFTC and that it will continue to sue states that violate federal jurisdiction. The CFTC has previously sued Wisconsin, Illinois, Arizona, Connecticut, and New York.

Paradigm general partner Dan Robinson proposed the "Proof of Address Control Timestamp" (PACTs) mechanism, aimed at providing a protection path for Bitcoin addresses against potential threats from quantum computing.This solution allows holders to generate address control proofs through BIP-322 and create on-chain commitments using a random salt value, completing time anchoring with OpenTimestamps to establish ownership proof without disclosing wallet information. If quantum-vulnerable addresses are frozen in the future through a soft fork, users can submit STARK zero-knowledge proofs to unlock their assets when spending. This mechanism also provides a potential recovery path for wallets derived from BIP-32, but its implementation still relies on Bitcoin introducing STARK verification capabilities and gaining community consensus.

Members of the U.S. Senate Banking Committee announced a compromise text on the "Clarity Act" on Friday, which allows cryptocurrency companies to continue implementing stablecoin reward programs but prohibits them from offering stablecoin yields equivalent to bank deposit functions or economic benefits.

Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

According to SBS Biz, the Personal Information Protection Commission of South Korea has launched an investigation into Upbit and Bithumb for sharing order books with overseas exchanges, focusing on whether there is any cross-border transfer of personal information in the process. The commission has completed written investigations and on-site inspections and is currently in the phase of determining legality, with results expected to be finalized in the second half of the year.An order book is a list of buy and sell orders on an exchange, and sharing it with overseas entities can increase liquidity. However, if user identification information is transmitted along with it, it may violate personal information protection laws (cross-border transfers require user consent). It is reported that Upbit shares its order book with Southeast Asia's Upbit APAC and the Tether market, while Bithumb has shared its order book with Australia's Stellar.

The Lido research forum has launched a new proposal suggesting that the DAO authorize a temporary reduction of the first loss protection trigger threshold for the EarnETH treasury during the Kelp event. According to current rules, the protection mechanism of Lido Earn only triggers when the treasury loss exceeds 1% of the holdings. However, the proposal points out that if the shortage of rsETH is resolved through DeFi United, the actual loss may be less than 1%.To ensure that EarnETH users receive full compensation, the proposal suggests a one-time exception during this event, allowing the use of the first loss fund to cover losses below the 1% threshold. The current estimated residual borrowing rate loss is about 400 to 600 ETH.The proposal emphasizes that this move is a one-time arrangement for user protection, brand reputation, and business considerations, and does not change the general 1% rule. Since the rsETH event is expected to be resolved within 5 to 10 days, and the standard voting window is 7 days, the proposal also has a sense of urgency.

The proposer of the "Bitcoin Strategic Reserve Act," U.S. Senator Cynthia Lummis, stated that concerns about the developer protection provisions of the "CLARITY Act" are not a new issue. Efforts are currently underway to improve these provisions, aiming to ensure the safety of non-fund transfer developers while holding wrongdoers accountable.

The Bank for International Settlements (BIS) released a report indicating that cryptocurrency exchanges are gradually providing bank-like services, such as lending and earn products, but lack the regulation and deposit protection found in traditional financial systems, posing systemic risks.The report states that these high-yield products are essentially closer to "unsecured loans," where user assets are often used by the platform for high-risk operations such as lending, trading, or market making, and users only hold a creditor position against the platform. If the platform encounters problems, users will be directly exposed to repayment risks. The BIS also noted that leading cryptocurrency platforms have evolved from single exchanges into "multi-functional intermediaries," integrating the functions of banks, brokerages, and exchanges, but lacking transparency and risk isolation mechanisms. The previous collapses of Celsius Network and FTX are typical cases of such structural risks. Additionally, the report mentioned that the flash crash in the cryptocurrency market in October 2025 triggered approximately $19 billion in forced liquidations, highlighting the chain reaction risks under high leverage and opaque structures.

According to official news, KelpDAO stated that over the past few days, the team has been continuously advancing the handling of related events with the support of partners, allies, and the community. Discussions are progressing in a positive direction, and efforts are being accelerated to reach a suitable solution. The project party emphasized that it always adheres to the core principle of "user first," and subsequent measures will be gradually implemented with the aim of safeguarding the overall interests of users.In the past four days, the Kelp team has been working around the clock in collaboration with multiple parties, maintaining close communication with all relevant parties, and making substantial progress on several potential solutions. This includes measures taken by the Arbitrum Security Council to freeze the stolen funds, as well as SEAL 911 participating in the preliminary investigation to provide objective and clear analytical support for the incident.Kelp stated that the current focus of work remains on protecting user asset security and strengthening the protocol itself. This incident is not only of critical significance to the project but also has enlightening value for the entire industry. The team will continue to disclose subsequent progress through official channels and thanks the ecological partners and community for their ongoing support.Previous reports indicated that the KelpDAO hacker has essentially laundered $175 million in ETH into BTC.

Lido stated on platform X that its EarnETH treasury was affected by the theft of 116,500 rsETH (approximately $29.2 million) from the Kelp DAO cross-chain bridge on April 18.EarnETH holds approximately $21.6 million in rsETH risk exposure through leveraged positions in rsETH/ETH on Aave, accounting for about 9% of the total assets in the treasury. The EarnETH team is currently actively deleveraging to reduce risk, and the outcome depends on the final decisions made by Kelp, LayerZero, and Aave regarding loss sharing and bad debt handling.Lido further stated that EarnETH has a $3 million "first loss protection mechanism" funded by the Lido DAO treasury, which will be used to cover losses if necessary. The treasury has currently suspended redemption processing to assess the losses. This incident does not affect stETH and wstETH, and the core staking protocol of Lido is not involved.

According to RHEA Finance's official disclosure, the NEAR ecosystem lending protocol RHEA Finance (formerly known as Burrow Finance) experienced a margin trading feature hack, resulting in a loss of approximately $18.4 million.The attacker began laying the groundwork several days prior by creating multiple fake token pools on Ref Finance and injecting liquidity, constructing a malicious exchange route that exploited a vulnerability in the protocol's slippage protection mechanism—this mechanism did not account for the scenario where intermediate tokens were reused when calculating the minimum output of multi-step exchanges—leading to the borrowed debt tokens being directed into fake token pools controlled by the attacker, triggering a large-scale forced liquidation that ultimately drained the protocol's reserve pool. During the attack, the attacker deleted a total of 55 intermediate accounts to cover their tracks. Currently, the attacker has returned approximately 3.359 million USDC and 1.564 million NEAR to the RHEA lending contract, while another 4.34 million USDT has been frozen (of which Tether froze 3.291 million and NEAR Intents froze 1.053 million). The protocol contract has been suspended, and the team is collaborating with centralized exchanges for joint tracking and has notified relevant law enforcement agencies.

According to DL News, STS Digital's CEO Maxime Seiler stated that Bitcoin traders are increasingly positioning themselves for a price decline.In a report, he noted that the demand for put options is significantly higher than that for call options, with investors paying a premium for downside protection while selling off bullish bets, reflecting a sense of panic in the market. This bearish signal comes as Bitcoin's trading price hovers slightly above $70,000.Previously, Bitcoin fell nearly 4% over the weekend due to President Trump's threat to block the Strait of Hormuz. On Monday, the U.S. Central Command announced that the Navy would intercept all vessels entering or leaving Iranian ports starting at 10 AM Eastern Time, causing oil prices to rebound above $100 per barrel.High oil prices mean rising inflationary pressures, which will be a major focus for global central bank governors at their meeting in late April. The prices of risk assets like Bitcoin are highly dependent on the policies of these institutions, as they determine the money supply in the financial system. The unresolved Middle East conflict will remain a focal point for the market this week.

Sky Governance announced on April 7 two structural upgrade proposals aimed at strengthening the capital protection framework of the protocol. The two proposals are: implementing a stronger solvency buffer mechanism and adopting a more sustainable staking reward model, with the goal of consolidating the long-term stability of the protocol and placing credibility above the pursuit of short-term gains.Sky Protocol pointed out that its yield-bearing stablecoin sUSDS is the largest in its category, attributing this success to the protocol's unique risk positioning compared to its competitors.

According to the official announcement, Binance spot will implement a spot price range protection mechanism, allowing orders to be executed only within a dynamic price range.Starting from April 14, 2026, the spot price range protection mechanism (PRER) will be gradually implemented to ensure that trading prices reflect a fair and orderly market.

VanEck's research director Matthew Sigel analyzed in a post on the X platform that the current protective demand in the Bitcoin derivatives market has risen to the historical 99th percentile, which is typically seen as a "contrarian buy signal" under extreme risk-averse market sentiment, and he judges that the market is currently suitable for establishing long positions.The VanEck Digital Transformation ETF (NODE), which Matthew Sigel also manages, has risen 27% since its inception, while Bitcoin has fallen 33% during the same period, achieving lower volatility performance through diversified allocation and focusing on profitable sectors. However, he also warns that if the massive capital expenditures in the artificial intelligence (AI) sector do not generate corresponding returns, it could pose substantial pressure on the market, especially in the context of a concentration in S&P 500 constituents.Note: Percentile is a statistical position concept, with the 99th percentile representing a relatively extreme level, and the 50th percentile representing the median level.

According to Bloomberg, the Irish government officially launched the testing phase of the digital wallet on April 3 local time, which includes an age verification feature.According to a statement from the Irish Department of Public Expenditure and Reform, this digital ID will support age verification on social media platforms, aiming to protect children and adolescents from online harm.

Polygon announced the launch of the Private Mempool, a private transaction submission entry that protects each transaction from front-running and sandwich attacks.Simply replace the RPC address with the corresponding private entry to use this feature, with no additional operations required.
