1. US Labor Dept Proposes 401(k) Alternative Asset Rules link
The U.S. Department of Labor has proposed a rule to ease restrictions on including alternative investments such as private equity and crypto assets in 401(k) retirement plans. It clarifies that fiduciaries must conduct a prudent evaluation based on factors including performance, fees, liquidity, valuation, and complexity before introducing such assets. Fiduciaries complying with this process will be granted “safe harbor” protection to reduce litigation risks. This rule serves as an initial step to implement an executive order by Donald Trump and is currently in the public comment period.

The Central Bank of Cuba (BCC) has approved 10 enterprises, including 9 micro, small and medium-sized enterprises and 1 joint venture, to use cryptocurrencies for international payments for the first time. The relevant licenses were published in the Official Gazette on March 23. The licenses are valid for one year and may be renewed. Enterprises may only use crypto assets for cross-border payments related to their main business, and must conduct operations through virtual asset service providers (VASPs) licensed by the Central Bank of Cuba. They are also required to report transaction amounts, currencies used and information on intermediary service providers to regulators on a quarterly basis. This is the first time Cuba has issued operational licenses for cryptocurrencies directly used for cross-border payments to domestic enterprises.
6. Bithumb Delays IPO to 2028 Amid Issues link
Bithumb has announced that its IPO plan is expected to be delayed until 2028, further postponing its previous target of listing in the second half of 2025. The company is still in the preparation stage, focusing on improving accounting policies, internal controls and internal review procedures, and has signed a consulting agreement with Samjong KPMG through 2027. Despite posting revenue of approximately 651 billion won (about 430 million US dollars) in 2025 and holding a market share of over 30%, recent internal issues and regulatory pressure continue to affect its listing process.
7. Dunamu 2025 Revenue ₩1.56T, Down 10% YoY link
According to Dunamu, the operator of Upbit, in its 2025 annual audit report, the company posted revenue of 1.56 trillion won (approximately 1.027 billion US dollars) in 2025, a year-on-year decrease of 10.04%; operating profit of 869.2 billion won (approximately 573 million US dollars), down 26.7% year on year; and net profit of 708.9 billion won (approximately 467 million US dollars), a year-on-year drop of 27.9%. The company stated that the performance decline was mainly due to lower trading volume of crypto assets compared with 2024. According to another announcement, Dunamu plans to pay a cash dividend of 5,827 won per share, totaling about 199.99 billion won (approximately 132 million US dollars).
8. Google Quantum AI: Crypto Wallet Breakable With Less Quantum Resources link
In a new whitepaper, Google Quantum AI states that the resources required for future cryptographically capable quantum computers to crack the 256-bit elliptic curve cryptography (ECC) wallet signature systems widely used in cryptocurrencies are lower than previously estimated. According to Google, under standard hardware assumptions, fewer than 500,000 physical qubits could complete the crack within minutes. The company is urging the blockchain industry to expedite its migration to post-quantum cryptography (PQC) to mitigate long-term security risks.
Haseeb, Managing Partner at Dragonfly, commented that Google’s research has made the quantum cracking of ECDSA approximately 20 times more efficient than prior estimates, advancing the industry’s timeline for post-quantum migration to around 2029. He noted that Google did not even disclose the specific quantum circuits, instead verifying the results via zero-knowledge proofs, underscoring the high level of concern regarding this risk.
9. Coinbase Gets OCC Conditional Nod for National Trust Bank link
Coinbase Global has received conditional preliminary approval from the U.S. Office of the Comptroller of the Currency (OCC) to establish a national trust bank. This license is positioned for custody and market infrastructure businesses. The OCC federal trust charter will provide a unified federal regulatory framework for Coinbase’s custody business, enabling Coinbase to offer regulated services including digital asset custody, tokenized asset management, and transaction settlement.
10. Drift Protocol Hacked for $285M link
Around April 2, 2026, multiple on-chain analytics firms and media outlets reported abnormal capital outflows from Drift Protocol, an integrated derivatives and lending protocol in the Solana ecosystem. The project confirmed it was under attack, which ultimately resulted in approximately $280 million worth of funds being stolen from the protocol. The protocol has suspended deposits and withdrawals and is cooperating with security firms, cross-chain bridges, and trading platforms to handle the incident.
Drift Protocol issued a statement on the security incident, saying a malicious actor gained unauthorized access to the protocol through a new attack method involving durable nonce and quickly seized control of the Drift Security Council. Drift stated that this was a highly sophisticated attack operation, apparently planned over several weeks and executed in phases, including techniques such as pre-signing transactions via durable nonce accounts and delayed execution.
According to Drift’s current investigation findings, the incident was not caused by vulnerabilities in Drift’s programs or smart contracts, and there is no evidence that the relevant mnemonic phrases were compromised. Drift believes the attacker obtained unauthorized or disguised transaction approvals prior to execution, with the durable nonce mechanism and complex social engineering tactics likely playing a key role. A total of approximately $280 million in assets were transferred out of the protocol in the incident.
Drift outlined the main steps that allowed the attacker to carry out the breach: first, pre-deploying an access path through durable nonce accounts; then obtaining sufficient approval authority within the multi-signature setup, specifically 2/5 multi-signature approvals; subsequently executing a malicious admin privilege transfer within minutes to gain protocol-level control; and finally using that authority to introduce malicious assets and remove all existing withdrawal restrictions, enabling the theft of held funds.
All funds deposited in the lending module, vaults, and trading accounts have been affected. Unaffected assets include DSOL not deposited into Drift, including assets staked with Drift Validator, as well as insurance fund assets, which will be withdrawn from the protocol and moved to a more secure environment for protection.
As a preventive measure, Drift has frozen all remaining protocol functions and updated its multi-signature configuration to remove compromised wallets.
The incident has spilled over to multiple DeFi protocols in the Solana ecosystem. Projects including Reflect Money, Ranger Finance, Neutral Trade, Elemental DeFi, Project 0, Lulo Finance, Asgard Finance, DeFi Carrot, Pyra, xPlace, and Fuse Wallet have confirmed being affected, with some suspending minting, redemption, or deposit and withdrawal functions. Ranger Finance reported an exposure of approximately $900,000, accounting for about 6% of its TVL. Pyra stated it has suspended related card services as user funds earning yields on Drift were impacted.
Charles Guillemet, Chief Technology Officer of Ledger, stated that the attack was not a smart contract vulnerability but a long-term covert compromise of the multi-signature mechanism. The hacker is suspected to have gained control of multi-signature holders’ devices or private keys and misled operators into approving malicious transactions. The method closely resembled the Bybit incident last year, which was linked to the North Korean hacking group (DPRK). He called on the industry to improve endpoint detection capabilities and adopt hardware-backed clear-text signing to prevent operational risks.
Hayden Adams, founder of Uniswap, stated bluntly that centralized projects must stop labeling themselves as DeFi; if admin keys can drain all funds, they are essentially CeFi. Omer Goldberg, founder of Chaos Labs, added that Drift’s signing keys held full control over market creation, oracle assignment, and withdrawal limits with no time locks, and the attacker reportedly completed the fund theft in roughly 10 seconds.
