In May 2026, the decentralized wallet imToken announced its strategic direction for the next decade on the occasion of its tenth anniversary, proposing to evolve from a "Trusted Main Wallet" to a "Personal Digital Hub," helping users control their assets, identity, permissions, and intelligent actions in an open and intelligent internet.imToken stated that in the past decade, the wallet primarily focused on Store, Send, and Stake services for users; facing the era of AI intelligence, the wallet needs to add a fourth core product proposition: Sign. Sign is no longer just about signing transactions, but rather the foundational interface for users to express intentions, grant permissions, set rules, delegate actions, and revoke authorizations.imToken Founder & CEO Ben He stated: "AI will make autonomous action increasingly abundant, but what will truly be scarce is control. In the next decade, imToken hopes to help users continue to control their digital world in the intelligent era."imToken also upgraded its brand proposition to: Your Digital World, Under Your Control.

Aleo released the privacy stablecoin white paper "Stablecoin Privacy," stating that the privacy layer is the key infrastructure missing for blockchain payment rails to be adopted by mainstream institutions. Aleo indicated that as the GENIUS Act provides opportunities for the widespread adoption of stablecoins, the issue of permanently public transaction information on public blockchains may still hinder institutions from using stablecoins in scenarios such as payroll, fund management, and vendor payments.Aleo claims that existing solutions do not adequately meet the needs of institutions in terms of privacy protection and risk management. The white paper proposes a permissionless private stablecoin architecture based on Aleo, which introduces programmable risk mitigation mechanisms while protecting transaction privacy through zero-knowledge technology and programmable smart contracts, allowing institutions to conduct private transactions without sacrificing compliance and risk control.It is reported that the team members behind this white paper have long been dedicated to research at the intersection of cryptography, policy, and financial systems. Aleo's Global Policy Director Yaya J. Fanusie, member of the Crypto Innovation Council and former Global Financial Crimes Compliance Officer at Coinbase Valerie-Leila Jaber, and cryptographer and Johns Hopkins University Computer Science Professor Matthew Green possess rare practical experience in private payments, financial regulation, and zero-knowledge cryptography.

The prediction market platform Polymarket believes that its competitor Kalshi may be engaging in corporate espionage against its New York office and employees. Polymarket's marketing director confirmed that the company is conducting an internal investigation and stated that "there are too many coincidences," suspecting that Kalshi has malicious intentions.Reports indicate that Polymarket has compiled an internal dossier titled "Imitators," documenting about a dozen suspicious incidents. These include Polymarket's original plan to launch a free grocery flash event on February 12, while Kalshi launched a similar event about 9 days earlier; additionally, Polymarket was set to announce its perpetual contract product plan on April 21, but about 1 hour before the announcement, the tech media The Information reported that Kalshi was also preparing to launch a similar product.Polymarket employees are also concerned that the venture capital firm Paradigm, which supports Kalshi, has an office directly across from theirs, posing a risk of employees' computer screens being spied on. It is reported that Polymarket installed privacy film on some office windows this spring.In response, a Kalshi spokesperson denied all allegations, stating that Polymarket's suspicions are "sad and almost delusional."

According to a report titled "Stablecoins: Waiting for Regulation" released by the UK House of Lords Financial Services Regulatory Committee, the global market capitalization of stablecoins has exceeded $310 billion, but the UK pound stablecoin market is still in its infancy, and the construction of the regulatory framework is clearly lagging behind the United States (GENIUS Act) and the European Union (MiCAR).The report criticizes several aspects of the current regulatory proposals from the UK Financial Conduct Authority (FCA) and the Bank of England, focusing on:• The Bank of England's requirement for systemic stablecoin issuers to deposit at least 40% of reserve assets in non-interest-bearing central bank deposits, which the industry believes will severely harm issuers' profitability and the international competitiveness of the UK market;• The proposed holding limits (individual £20,000, corporate £10 million) are considered extremely difficult to implement and may stifle the development of the pound stablecoin market;• The T+1 redemption requirement will impose a significant operational burden on issuers;• The Prudential Regulation Authority (PRA) restrictions on deposit-taking institutions issuing stablecoins under independent brands are deemed overly stringent.The report also acknowledges the liquidity support loan mechanism proposed by the Bank of England, considering it an innovative regulatory measure that surpasses other major jurisdictions. The committee calls on regulatory agencies to strictly adhere to the established timeline, ensuring that the complete regulatory framework comes into effect as scheduled on October 25, 2027, and recommends adopting a principle-based, technology-neutral regulatory approach to achieve a reasonable balance between financial stability and market innovation.

The tokenized asset platform RootData has released the "Exchange Tokenized Asset Provider and License Map," systematically sorting the paths and regulatory licenses of providers and brokers in mainstream exchanges such as Binance, Gate, Bitget, and Bybit for products like real stocks, TradFi stocks, CFD contracts, and tokenized stocks. The map shows that the current stock-type assets on exchanges have gradually formed a three-tier structure: real stock spot mainly relies on a regulated brokerage system for securities execution and custody; TradFi stocks are primarily based on CFDs/Perps; tokenized stocks are mainly supported by solutions like Ondo and xStocks. Among them, Binance currently accesses Alpaca Securities through Nest Trading to provide real US stock/ETF exposure and has launched Ondo stock tokens in the Alpha zone, with plans to introduce bStocks later; Gate's real stock collaboration is with AIpaca, CFDs adopt the MT5 model, and perpetual contracts are self-operated by the platform; Bybit currently mainly uses the Backed Finance (xStocks) solution; Bitget provides 1:1 US stock/ETF tokenized products through its own Reality (rToken) brand. RootData believes that as the tokenized stock market heats up, competition among exchanges is gradually shifting from merely launching products to underlying broker capabilities, real securities custody, and regulatory license capabilities, with licensed brokers like Alpaca Securities strengthening their infrastructure roles across multiple platform ecosystems.

The U.S. Securities and Exchange Commission (SEC) has released the "Draft Strategic Plan for Fiscal Years 2026-2030" and is seeking public comments. The goals proposed in the draft include "providing a solid regulatory foundation for digital assets and distributed ledger technology through a rational, coherent, and principle-based approach."The document points out that a modernized framework will also ensure that custody, trading, and staking services can operate under appropriate regulation, avoiding duplicative or conflicting requirements, while clarifying jurisdictional issues between the SEC and the Commodity Futures Trading Commission. This coordination aims to ensure that the crypto market has clear, principled, regulation-based rules of the game, promoting innovation while maintaining the highest level of investor protection. Furthermore, the document suggests that the agency's responsible use of artificial intelligence and blockchain technology could further enhance regulation, reduce costs, and unlock new efficiencies.

The Zcash Foundation announced the release of the Zebra 4.5.1 version update to fix a consensus-level security vulnerability and strongly recommends that all node operators upgrade immediately.The vulnerability, identified as GHSA-2prc-cj5x-4443, involves a sigop (signature operation count) statistical error in P2SH transactions, which could lead to potential consensus fork risks. This fix corrects the incomplete patch issue from the previous 4.5.0 version, which was just released yesterday.The Zcash development team stated that the problem originated from discrepancies in sigop counting logic across different implementations, which could cause nodes to produce different results when validating transactions, thereby affecting on-chain consensus consistency. The fix was implemented by reverting and adjusting the Rust implementation logic to ensure alignment with the expected behavior of the protocol.The Zcash Foundation emphasizes that there is currently no workaround for this issue, and upgrading to 4.5.1 is the only way to ensure that nodes remain on the correct chain and avoid potential fork risks.

Michael Saylor, the founder of Bitcoin treasury company Strategy, has once again released information related to the Bitcoin Tracker.According to previous patterns, Strategy always discloses information about increasing Bitcoin holdings on the second day after relevant news is released.

Regarding the attack on the Kelp rsETH LayerZero V2 bridge that occurred on April 18, Aave released a post-incident investigation on the X platform, emphasizing that the exposure was primarily due to third-party bridge infrastructure rather than the protocol itself. The attacker executed an RPC poisoning attack targeting a single validator of LayerZero, forging a cross-chain message. This led to the release of 116,500 rsETH on the Ethereum side without actual destruction on Unichain. The attacker subsequently deposited the stolen rsETH into Aave V3 (Ethereum Core and Arbitrum), borrowing approximately 82,650 WETH and 821 wstETH.The Aave Protocol Guardian and Risk Steward immediately implemented protective measures for the rsETH and WETH reserves. Currently, the WETH and rsETH markets in the affected V3 deployments are operating normally. The rsETH held by the attacker on Arbitrum has been destroyed, the LayerZero OFT adapter has been fully recharged in five batches, rsETH support has been fully restored, and Kelp has reopened the withdrawal, bridging, and claims functions for rsETH. The WETH LTV in the affected markets has been reset to pre-attack values, and Aave V3 is fully operational across all markets except for rsETH.The Arbitrum DAO has voted to authorize the transfer of frozen ETH to Aave LLC, and it is currently awaiting on-chain execution. The court is still reviewing the substantive content of the injunction, and Aave LLC will continue to comply with the injunction during the court's deliberation. Ongoing projects include: the Aave risk framework from Llama Risk, the bridging assessment framework, the release of evaluation reports for currently live assets, on-chain execution of Arbitrum DAO votes, and the court's review of the injunction.

Circle released a quantum security white paper, proposing a phased upgrade plan covering Arc, USDC, smart contracts, and the validator system to address potential security risks posed by future quantum computing.

Circle released the "Post-Quantum Security White Paper," proposing a phased post-quantum resilience roadmap focused on the long-term security of the Arc blockchain ecosystem.The roadmap covers multiple technical directions, including quantum secure signatures, private execution environments, validator hardening, infrastructure migration, and account recovery, applicable to core components such as the Arc network, USDC, smart contracts, and validators.Circle stated that it plans to provide post-quantum signature support when the Arc mainnet launches (in 2026) to enhance the ecosystem's ability to respond to future quantum computing threats.

The U.S. Commodity Futures Trading Commission (CFTC) has jointly issued staff guidance from its divisions of Market Oversight, Clearing, and Risk, addressing regulatory expectations and compliance requirements for the increasingly prevalent 24/7 trading, clearing, and settlement models, encouraging market innovation while ensuring compliance.The guidance emphasizes that regulated trading platforms, swap execution facilities, derivatives clearing organizations, and futures brokers must comply with the Commodity Exchange Act (CEA) and related regulatory rules when expanding around-the-clock trading, and must proactively assess risk management and operational arrangements.The CFTC points out that the adaptability of different asset classes to 24/7 trading varies, with derivatives related to crypto assets being more suitable for around-the-clock trading and clearing due to their digital infrastructure and global continuous trading characteristics; whereas traditional commodity derivatives like agricultural products may not be suitable for full 24/7 operation due to their regional and trading structure characteristics.CFTC staff stated that relevant institutions should ensure compliance with regulatory frameworks and risk control requirements while promoting the continuous evolution of the market to support "responsible market innovation."

The Zcash Foundation has released the node client Zebra version 4.5.0 update, which includes multiple security fixes, including a critical consensus vulnerability and several high-risk denial of service (DoS) issues. All node operators are strongly advised to upgrade immediately.It is reported that this core fix includes a sigop counting error caused by P2SH script parsing (which may lead to a consensus fork with zcashd), a defect in the NU5 block validation cache logic, a risk of transparent address balance overflow crashes, as well as multiple crashes and resource exhaustion vulnerabilities in RPC interfaces and memory pool handling. Additionally, some vulnerabilities can be exploited by malicious nodes, leading to node freezes, reboot loops, or even permanent shutdowns.

Sei releases the next-generation protocol upgrade "Giga" roadmap, planning to significantly enhance transaction performance by restructuring the execution client, state management, and consensus mechanism. Core upgrades include: Ares execution client (optimizing performance through pipelined execution and asynchronous processing); Eidos state management (replacing the Merkle tree with a flat key-value store, separating hot data from cold archives); Autobahn consensus mechanism (targeting 200,000 TPS and 400 milliseconds finality, with the internal test network already achieving 5 Gigagas processing capability); Sedna private memory pool (introducing a cryptographic transaction propagation mechanism); and gradually phasing out Cosmos SDK and CosmWasm through SIP-3, transitioning to a pure EVM architecture.

Aave Labs has released an ARFC proposal, suggesting the establishment of a standardized technical asset listing framework for Aave V3, V4, and Aave Horizon, setting unified technical requirements for asset listing, parameter expansion, and ongoing monitoring. The framework covers core areas such as ERC20 compatibility, oracles, permission control, minting and burning logic, pause and blacklist mechanisms, upgradability, exchange rates and yield mechanisms, token architecture, cross-chain bridge risks, audit and security history, and external dependencies. This framework does not replace market risk analysis and governance judgment but provides a technical qualification baseline.The framework aims to address "hidden risks" such as unlimited issuance, weak upgrade permissions, inconsistent bridging supply, opaque redemption paths, and reliance on off-chain custody. These issues may directly threaten the protocol's solvency, liquidation systems, and collateral parameter security. The framework particularly emphasizes additional scrutiny for cross-chain assets, yield-bearing assets, and off-chain dependent assets such as RWAs, including bridge structures, off-chain legal arrangements, custody mechanisms, and supply integrity. Assets with significant technical flaws may face reduced borrowing limits, restricted collateral parameters, delayed launches, or even recommendations to deny access to the protocol in the future.

Coinbase released the Solana Validator Performance Report for the first quarter of 2026, disclosing its staking scale, infrastructure upgrades, and network optimization progress. It revealed that Coinbase has staked approximately 40.48 million SOL on the Solana network, accounting for 9.52% of the total network staking, with validator nodes distributed across 6 countries/regions.The report also noted that Coinbase has implemented a near-zero downtime (ZDD) upgrade mechanism, ensuring that the validator update process does not affect network security and stability through hot swapping and dual-signature protection. It supports multi-client systems such as Harmonic, Jito, JitoBAM, Firedancer, and Rakurai to enhance the diversity and resilience of the Solana validator ecosystem while avoiding the centralization risks of a single scheduling strategy.

Morpho officially released the "Morpho Midnight White Paper," announcing the launch of a new non-custodial protocol designed specifically for the fixed-rate, fixed-term credit market.
