Arbitrum, created by the Offchain Labs team, is an Ethereum Layer2 scaling solution based on Optimistic Rollup technology. It leverages the ability to communicate between L1 and L2, allowing any form of Ethereum asset to be transferred between Layer 1 and Layer 2 without the need for trust. Even though Arbitrum transactions are still settled on Ethereum, only raw transaction data is submitted to Ethereum, with execution and contract storage occurring off-chain. This makes the gas fee required on Arbitrum much smaller than on the mainnet, and contracts are fully compatible with no gas limit.
According to The Block, the DeFi lending protocol Radiant Capital has announced it will officially cease operations. The protocol suffered a hack in October 2024, losing approximately $51 million; the attacker gained unauthorized access by deploying backdoor contracts on Arbitrum and BNB Chain. Earlier in 2024, the protocol had also been hit by a flash loan attack, resulting in a loss of roughly 1,900 ETH (approximately $4.5 million). After 18 months of recovery efforts, Radiant Capital stated that it has neither recovered a significant portion of the stolen funds nor secured new financing, declaring that “the DAO has no viable path forward.” The protocol will now enter a “maintenance mode”: its frontend and smart contracts remain accessible, allowing users to withdraw funds, repay loans, and manage positions. Any funds recovered in the future will be returned to affected users.

Blockworks aims to fill this gap through a "data + disclosure + investor relations" tripartite architecture. (CNBC)
According to Fortune, blockchain startup Nava has announced the completion of an $8.3 million seed funding round, co-led by Polychain and Archetype, aiming to prevent anomalous operations by AI financial agents through a custody and verification framework. Nava’s solution locks funds via custodial services; once an AI agent proposes a transaction, an on-chain verification mechanism assesses whether the transaction aligns with the user’s intent—only compliant transactions are executed, while non-compliant ones leave funds in custody. All verification decisions are publicly recorded on the blockchain for reference by other AIs. Nava currently operates as a Layer 3 blockchain on Arbitrum and plans to deploy a parallel chain on Tempo; it will also issue a native stablecoin in the future to support protocol operations. Nava’s infrastructure serves both individual users and institutions, enhancing asset security and transaction transparency.

Aave has published a post-mortem of the April 18 rsETH incident, stating that the rsETH LayerZero V2 cross-chain bridge of liquid staking protocol Kelp accepted a forged message during a cross-chain transfer from Unichain to Ethereum. This caused the adapter on the Ethereum side to release 116,500 rsETH without a corresponding burn on the Unichain side. Aave stated that the attack occurred on a third-party cross-chain bridge infrastructure. However, the attacker deposited the stolen rsETH into 8 Aave V3 positions, borrowing 82,650 WETH and 821 wstETH, which impacted the Aave market.Aave stated that the attacker's rsETH on Arbitrum has now been burned. The LayerZero OFT adapter has replenished 116,131.72 rsETH in 5 batches, and the asset backing for rsETH has been fully restored. The affected WETH and rsETH markets have returned to normal.
Odaily Odaily PaperImperium, the head of MegaETH, disclosed on X platform that documents from the U.S. District Court for the Southern District of New York show that a U.S. court has issued an injunction against the Arbitrum DAO, prohibiting it from transferring approximately $71 million in ETH assets that were previously frozen during the KelpDAO hacking incident. In response, on-chain detective ZachXBT posted on X platform, stating that certain U.S. law firms are using his investigative work and on-chain forensics to help victims of some hacking incidents file legal claims. However, this practice may actually slow down or hinder victims from receiving compensation or recovering funds.ZachXBT added that in previous hacking incidents involving the Lazarus Group, such law firms often stepped in after on-chain fund tracking or freezing was completed, proposing subsequent legal actions that were weakly related to the crypto incidents themselves. Similar "free-riding claims" strategies were used in events like Harmony and Bybit. He called on the crypto community to establish a DAO to resist such practices.
: MegaETH lead PaperImperium disclosed on X platform a court document from the U.S. District Court for the Southern District of New York, showing that a U.S. court has issued an injunction against the Arbitrum DAO, prohibiting it from transferring approximately $71 million worth of ETH assets that were previously frozen in the KelpDAO hacking incident. The plaintiffs are attempting to use these funds to enforce outstanding judgment compensation in cases related to North Korea's involvement in terrorism, kidnapping, and other matters spanning several years. They have also filed a motion to serve legal notice to the Arbitrum DAO via alternative means, treating it as an accountable "partnership." The court document further notes that the Arbitrum DAO has a Security Council governed by ARB holders, which has the authority to take action in emergencies. As a result, relevant members who refuse to comply may face legal consequences such as contempt of court. Market observers believe that this case could set an important precedent for the U.S. judicial system to directly constrain DAO governance structures, further highlighting the compliance pressure faced by DeFi protocols under real-world legal frameworks.
Kelp DAO released a community update on X, noting that the recent rsETH security incident has remained tense over the past several days. However, with support from partners and the broader community, discussions are progressing in a positive direction, and efforts to identify an appropriate resolution are being accelerated. The guiding principles have already been reflected in initial actions, and subsequent updates will continue along this path, aiming for a win-win outcome for all stakeholders. Over the past four days, the Kelp team has engaged in in-depth communication with partners and other relevant parties. Specific progress includes: the Arbitrum Security Council has taken measures to freeze the stolen funds, and the SEAL 911 emergency response team has swiftly stepped in to conduct preliminary investigations, providing a clear and objective analytical perspective on the incident. While some developments have not yet been fully disclosed, related work continues to advance steadily. Kelp DAO stated that its current priority is safeguarding user assets and strengthening the protocol itself. This incident is also viewed as a critical test—not only for the project but for the broader DeFi ecosystem—and key follow-up developments will continue to be shared via official channels.
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.
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)
