Block's Cash App is gradually rolling out stablecoin payment functionality to its nearly 60 million users. According to sources familiar with the matter, the feature currently covers approximately 25% of users and is expected to reach full 100% availability within this week.The core functionality supports users in depositing and withdrawing via USDC, allowing free transfers of funds between external wallets and Cash App balances, and using stablecoins as a settlement tool for payments rather than as investment products. It currently supports transactions across four blockchain networks, including Solana, Ethereum, Polygon, and Arbitrum. Due to the irreversible nature of on-chain transactions, incorrect addresses or unsupported network transfers may result in permanent loss of funds.Block CEO Jack Dorsey previously stated that despite his longstanding preference for Bitcoin, user demand for stablecoins has prompted the company to adjust its strategy.

Odaily Chainalysis posted on X platform, stating that prior to the THORChain theft, wallets suspected to be linked to the attacker had been transferring funds through Monero, Hyperliquid, and THORChain for several consecutive weeks. As early as late April, the attacker-associated wallets deposited funds into Hyperliquid positions via Hyperliquid and the Monero privacy bridge. These funds were subsequently converted to USDC and transferred to Arbitrum, then bridged to Ethereum. Some of the ETH was then moved to THORChain to stake as RUNE for a newly joined node, which is believed to be the source of the attack.Subsequently, the attacker bridged a portion of the RUNE back to Ethereum and split it into four chains. One chain went directly to the attacker, passing through intermediate wallets before transferring 8 ETH to the wallet that would ultimately receive the stolen funds, just 43 minutes before the attack. The funds from the other three chains flowed in reverse. Between May 14 and 15, these wallets bridged the ETH back to Arbitrum again, deposited it into Hyperliquid, and transferred it into Monero via the same privacy bridge, with the final transaction occurring less than 5 hours before the attack commenced. As of Friday afternoon, the stolen funds remain untouched, but the attacker has demonstrated sophisticated cross-chain money laundering capabilities. The Hyperliquid to Monero path may be the next move.
Odaily News: Margaret Garnett, a U.S. District Judge in Manhattan, has approved Aave's asset recovery proposal, allowing the transfer of approximately $71 million in ETH previously frozen on Arbitrum and linked to North Korean-linked attacks, to a wallet controlled by Aave LLC, while preserving the legal claims of terrorism victim plaintiffs over the funds. The ruling also amended the earlier freeze notice against the Arbitrum DAO, permitting the transfer to be executed through an on-chain governance vote and exempting those who propose, vote on, or participate in the transfer from liability under the freeze order. The transfer is still subject to an official vote by Arbitrum's on-chain governance. (CoinDesk)
According to The Block, the Arbitrum DAO voted to release 30,765.6 ETH (approximately $70 million), previously frozen, to support the DeFi United initiative—aimed at offsetting Kelp DAO’s $292 million exploit loss last month. The vote passed with 90.96% support (182.2 million votes). The attack was allegedly carried out by the North Korean Lazarus hacking group, which exploited a vulnerability in LayerZero’s OFT cross-chain bridge—a single-validator configuration—which allowed attackers to steal 116,500 rsETH and pledge most of the stolen assets as collateral on Aave, resulting in roughly $190 million in bad debt. DeFi United has secured contributions from multiple parties, including 30,000 ETH from Consensys and Joseph Lubin, a 30,000-ETH loan from Mantle, and 5,000 ETH from LayerZero.
Aave stated that, per the previously disclosed technical recovery plan, the attacker’s rsETH positions on Ethereum and Arbitrum have been liquidated on Aave, and the associated collateral assets have now been transferred to the Recovery Guardian address designated by the AIP. Aave noted that this action did not impact other users, nor did it affect the Umbrella mechanism, and emphasized that this step is a critical milestone in the overall recovery roadmap, with further recovery efforts continuing as planned.
According to Cointelegraph, U.S. law firm Gerstein Harrow LLP has filed an application with the U.S. District Court for the Southern District of New York seeking a temporary restraining order and three writs of execution to prevent the Arbitrum DAO from transferring 30,766 ETH (valued at approximately $73 million) frozen following the Kelp vulnerability. The firm argues that its clients obtained default judgments against North Korea in U.S. courts in 2010, 2015, and 2016, entitling them to roughly $877 million in compensation—and contends that the stolen ETH constitutes North Korean-linked assets that should be used to satisfy those judgments. Kelp DAO suffered a $292 million hack on April 18; the attacker was identified as TraderTraitor, a subgroup of the North Korean state-sponsored hacking group Lazarus Group. Aave Labs previously proposed unfreezing the seized funds and transferring them into the “DeFi United” fund to compensate rsETH holders—but this legal action by Gerstein Harrow may significantly delay compensation for victims. Members of the Arbitrum DAO community have criticized the move, arguing it shifts the burden of North Korea’s debts onto another set of victims, thereby exacerbating the original harm. Gerstein Harrow had previously pursued litigation related to the 2023 Heco Bridge hack involving Teth
: Arbitrum DAO has initiated a governance vote to release the previously frozen 30,766 ETH to support DeFi United, a recovery plan following the Kelp DAO attack.These assets, worth approximately $71.1 million, were frozen by the Arbitrum Security Council on April 20. They were originally funds transferred to the Arbitrum network by the attacker. If the proposal passes, it will become the largest single source of funding for the DeFi United plan.In the early stage of voting, 16.9 million ARB have already been cast in support. Currently, there are no opposing votes. The voting is set to continue until May 7.
According to on-chain analyst Ember (@EmberCN), the rsETH incident on April 18 resulted in a funding shortfall of approximately 68,900 ETH (around $160 million): the hacker collateralized rsETH to borrow 99,600 ETH; after Arbitrum recovered 30,700 ETH, the remaining funds were fully converted by the hacker into BTC. The incident has now entered the remediation phase. Aave is coordinating the establishment of a “DeFi United” relief fund, which has so far received cumulative donations totaling 13,500 ETH (approximately $31.45 million). Donors include Lido Finance (2,500 stETH), ether.fi Foundation (5,000 ETH), Aave founder Stani Kulechov (5,000 ETH), Golem Foundation (1,000 ETH), as well as LayerZero and Ink Foundation (amounts undisclosed).
According to on-chain analyst PeckShield (@PeckShieldAlert), the KelpDAO attacker has transferred ETH from Ethereum to Arbitrum via the Across Protocol, swapped it for USDT, and then routed the funds to TRON DAO via LayerZero.
According to on-chain analyst Specter (@SpecterAnalyst), the North Korean hacking group TraderTraitor began laundering stolen funds from KelpDAO at approximately 3 a.m. Beijing time today—just three hours after the Arbitrum Council froze 30.7 ETH (approximately $71 million). The attackers split the remaining funds across three wallets, holding roughly 25,000 ETH (~$57.6 million), 25,700 ETH (~$59.2 million), and 25,000 ETH (~$57.9 million), respectively. The third wallet immediately initiated laundering operations and now holds only about 3,800 ETH (~$8 million). The majority of the funds were bridged to the Bitcoin network via THORChain, with approximately 99% flowing through this protocol. As a result, THORChain’s daily trading volume surged to $211 million—more than ten times its 30-day average—and generated roughly $189,000 in fees. During this laundering process, the illicit proceeds were also commingled with funds stolen in the BTC Turk (2025) and Bybit (2025) hacks. To date, approximately 442 BTC (~$33 million) linked to these incidents have been traced on the Bitcoin network, and over 400 addresses have been utilized throughout the entire laundering operation.
Odaily News According to on-chain analyst Yu Jin's monitoring, the Arbitrum chain project team has frozen the 30,766 ETH ($70.97 million) that the KelpDAO hacker had placed on the Arbitrum chain. Through technical means, they transferred these 30,766 ETH from the hacker's wallet to the address 0x0000000000000000000000000000000000000da0, which is controlled by the Arbitrum chain. After the recovery of these 30,766 ETH, the hacker still holds 75,700 ETH ($175 million) on the Ethereum chain.
According to an official disclosure by Hyperbridge, the losses from the Token Gateway vulnerability incident on April 13 have been revised upward from an initial estimate of $237,000 to approximately $2.5 million. The increase stems primarily from losses incurred in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum. The attacker extracted roughly 245 ETH from related contracts, then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT tokens and dumping them onto illiquid markets. Currently, some of the stolen funds have been traced on-chain to Binance. Hyperbridge is collaborating with Binance’s compliance team and law enforcement agencies to investigate the incident. Polkadot-native DOT and products such as Intent Gateway remain unaffected. The Token Gateway and bridged DOT contracts on the four affected EVM chains remain suspended. An external audit of the patched MMR verification logic is underway, and bridging functionality will be restored upon completion of the audit.
