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.
Odaily报道: Satori Finance, a multi-chain decentralized exchange backed by investors including Polychain Capital and Coinbase Ventures, has announced it will cease operations and begin the closure process. The platform stated that due to "prolonged unfavorable market conditions," its revenue is insufficient to support continued operations, leading to the decision to gradually wind down. Users must withdraw their assets before 23:59 UTC on July 16, after which the platform will no longer be accessible.In 2022, Satori Finance completed a $10 million seed funding round led by Polychain Capital, with participation from Coinbase Ventures and Jump Crypto. The platform was deployed across multiple networks including Arbitrum, Optimism, and BNB Chain, and initially featured 25x leverage and an "points mining" incentive model. (The Block)
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.
: Web3 fintech startup Jia announced the completion of a $3 million seed funding round, with participation from Coinbase Ventures, Stellar Development Foundation, A100x Ventures, TCG, and Hashed Emergent.To date, Jia's total cumulative funding has reached $7.3 million. Jia currently operates multiple decentralized lending pools and introduces liquidity through networks including Base, Stellar, Arbitrum, and Polygon, while utilizing stablecoins for cross-border settlements to reduce remittance costs and settlement times.The new funds will be used to expand features such as corporate bank accounts and cash flow management.
Blockworks has announced the completion of a Series A extension funding round, achieving a post-money valuation of $192 million. The round was co-led by ParaFi Capital and Reciprocal Ventures, with support from Coinbase Ventures, MoonPay Ventures, and several other institutions and industry participants. The funding also attracted investments from over 20 founders and operators of ecosystem projects including Solana, LayerZero, Arbitrum, and Kraken, though the specific amount raised has not been disclosed.The company stated that while the crypto market has grown to a trillion-dollar scale lacking traditional capital market infrastructure, it still faces issues such as fragmented data, inconsistent disclosure standards, and a lack of investor communication mechanisms. 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.

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.

Lorenzo Valente, Director of Crypto Research at Ark, stated on X that Robinhood Chain is the clearest case study for examining the evolution of the ETH economic model over time.Since its inception, Robinhood Chain has generated a total of approximately $816,000 in revenue; Arbitrum, serving as the middleware provider, took a 10% cut, amounting to about $80,000; Arbitrum then paid settlement fees to the Ethereum mainnet, totaling approximately $1,538. A rough breakdown of the profit distribution in this model is as follows — Robinhood 89%; Arbitrum 10%; Ethereum 0.15%.If your thesis is "ETH is money," then Robinhood building an L2 within the Ethereum ecosystem is a major positive. However, if your thesis is "ETH is a revenue-generating asset," then this is an extremely bearish case.
