Mastercard is expanding its settlement network to support regulated stablecoins, planning to introduce stablecoin settlement, intraday settlement, as well as weekend and holiday settlement services to meet the demand for real-time fund movement.According to the introduction, the new settlement framework will operate in parallel with the existing fiat settlement system, providing financial institutions with more flexible liquidity management solutions. The first supported stablecoins include Circle-issued USDC, Paxos-issued PYUSD, USDG and USDP, Ripple-issued RLUSD, and SoFiUSD.The related services will cover blockchain networks such as Ethereum, Solana, Polygon, Base, Arbitrum, and XRPL.

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.
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.
