According to The Defiant, Arbitrum activated the ArbOS 61 Elara upgrade on August 20, adding optional protocol-level transaction filtering, priority fee support, and alternative data availability interfaces for dedicated chains, while adjusting the base fee management and expanding the Stylus contract capacity of Arbitrum One. The compliance filtering feature is turned off by default and requires the chain owner to actively configure external compliance service providers (such as TRM Labs or Chainalysis) and set rules, executing through a dual mechanism of simulated transactions and on-chain guardians.The priority fee feature is also turned off by default and requires the chain owner to enable it through pre-compilation. The collection of priority fees on Arbitrum One still requires a separate DAO vote. Elara also introduced the BaseFeeManager contract, allowing Offchain Labs to adjust the base fee within the DAO-approved range of 0.01 to 0.1 gwei, with a validity period of two years. The code size limit for Stylus contracts has been increased from 24KB to 96KB, which does not apply to Solidity contracts.

The Arbitrum development team stated that they are introducing zero-knowledge (ZK) proofs into the Arbitrum platform to achieve a multi-proof settlement model. Through ZK proofs, the settlement time of Arbitrum blocks to Ethereum L1 is expected to be reduced from several days to several hours, while enhancing user, cross-chain bridge, and protocol capital efficiency, and maintaining security through the multi-proof mechanism. Related capabilities are aimed at Arbitrum One and dedicated chains based on the Arbitrum platform. Offchain will subsequently submit upgrade proposals to the DAO.Current progress includes: the ability to run the same state transition functions in SP1 zkVM as in optimistic execution, generating ZK proofs for real mainnet block production; Stylus's WASM contracts can be proven alongside Solidity contracts; the team has launched an independent Rust verifier, making ZK proofs a first-class mode alongside standard verification; the BoLD settlement protocol has supported the acceptance of ZK proofs and is endorsed by a fast confirmation committee, while the original dispute games still serve as a fallback path, forming a multi-proof architecture that coordinates ZK proofs, proof committees, and fraud proofs.The team claims to be continuously reducing proof costs and will gradually merge related code into the Nitro main production path. The next steps include further optimizing proofs and shifting to Reth-based execution, completing L1 message inbox proofs, and integrating ZK settlement capabilities into node configurations for on-demand activation across chains.

According to Arbitrum's official disclosure, Robinhood Chain has accumulated a total fee revenue of 5 million dollars in just over a month since its launch. This chain is aimed at programmable financial scenarios and is designed to promote further integration of traditional finance with on-chain infrastructure.Robinhood Chain is built on Arbitrum technology, providing an execution environment for on-chain businesses related to the brokerage Robinhood. The progress of this fee revenue indicates that its early network activity and application deployment speed are relatively fast, reflecting the trend of institutions migrating to programmable finance.

The Offchain Labs research team has released advancements in zero-knowledge proof technology, covering areas such as proof acceleration, verifiable AI, and recursive security. Among them, the vector commitment scheme has reduced the proof generation time for 64,000 data entries from about 2 minutes to 32 milliseconds, achieving a speedup of approximately 4000 times; the new proof system Zaratan has achieved native full succinct proofs for integers for the first time, which can reduce the computational overhead of operations like RSA by about 5000 times; in terms of verifiable AI, a lightweight verification protocol can shorten the inference verification time for large models from several minutes to milliseconds.Arbitrum is exploring a multi-prover architecture that combines ZK proofs with fraud proofs and TEE to eliminate single points of failure and shorten L1 settlement cycles.

ChianCatcher news, Offchain Labs co-founder Steven Goldfeder tweeted that Arbitrum has been ahead of its time in several aspects. The team strongly advocated for interactive proof design (which was controversial at the time and has now become the standard for optimistic Rollups); chose to establish a business when the business model was still highly controversial; focused on DeFi when most people had not yet understood perpetual contracts and many had given up on DeFi; and launched a dedicated blockchain when the industry generally believed that more chains were unnecessary.Facing backlash each time, but now the industry is aligning with the direction they set from day one: building robust and high-performance financial infrastructure. Goldfeder is proud of the Offchain team for delivering world-class products at an incredibly fast pace and stated that they will continue to deliver, even if most people currently do not understand its necessity; the industry will soon understand.

According to Blockaid's monitoring, the Arbitrum ecosystem protocol AFX was attacked at 5:30 AM Beijing time, targeting a cross-chain bridge operated by the protocol. So far, approximately 24.15 million USDC has been stolen. Blockaid stated that it is working with the Arbitrum team to respond to the incident, communicate with the affected protocols, and assist in freezing the stolen funds.In addition, Offchain Labs co-founder Steven Goldfeder responded on the X platform, stating that the Arbitrum team has noted the reports of the cross-chain bridge attack on Arbitrum and is investigating. Goldfeder confirmed that the related transactions originated from a third-party protocol, and the Arbitrum native bridge was not attacked or exploited. The team will coordinate with the third-party team and provide more details.

According to Coindesk, Bernstein stated in a research report released on Monday that Robinhood's newly launched blockchain, Robinhood Chain, has performed strongly since its launch, quickly becoming one of the most active networks for decentralized trading.The report noted that since the mainnet went live on July 1, the DEX trading volume on Robinhood Chain reached $3.1 billion in the past week, ranking it among the top five chains by DEX activity. Currently, over 65,000 users hold approximately $13 million in tokenized stocks and $300 million in stablecoins on the chain.Bernstein believes that the early adoption of Robinhood Chain highlights the accelerated integration of tokenized real-world assets with the broader DeFi ecosystem. The network is built on Arbitrum, an Ethereum Layer 2, supporting Robinhood's tokenized stock products, providing 24/7 trading, self-custody, as well as on-chain use cases such as lending and collateralization, and has integrated with partners like Uniswap, Morpho, Lighter, Chainlink, and BitGo.The report also stated that although the current early trading volume is primarily driven by meme coins, Robinhood is expected to focus more on tokenized stocks, commodities, and other RWA assets, as well as perpetual contract business in the future.

According to Blockaid monitoring, the Lumi Finance protocol on Arbitrum is currently under attack, with approximately $270,000 in funds having been transferred out.

According to a report by Decrypt, Robinhood Chain quickly became one of the most active public chains in the crypto market just one week after its launch.Official data shows that Robinhood Chain processed over 17 million transactions in its first week, with nearly 350,000 active addresses and a protocol TVL of approximately $250 million. The cumulative trading volume on the DEX surpassed $1 billion. On Wednesday, the single-day trading volume reached $568 million, with a 24-hour DEX trading volume of about $433 million, surpassing Hyperliquid and ranking fifth in the entire network.Driven by the explosive growth of the ecosystem, Meme coins on Robinhood Chain performed strongly, with Cash Cat's market capitalization exceeding $180 million, and tokens like Dog In Hood, Hoodrat, and Robinhood Summer seeing increases of several times or even dozens of times. Reports indicate that some traders turned $800 into over $1 million, while another user increased $85 to $2 million.As the underlying technology provider for Robinhood Chain, Arbitrum (ARB) has benefited significantly, with ARB rising about 20% on the day. According to the mechanism, Robinhood Chain will return 10% of the protocol's net income to the Arbitrum ecosystem.However, the report points out that currently, the activity of Robinhood Chain is still mainly driven by Meme coins, and whether it can smoothly transition to RWA and other application scenarios planned by Robinhood in the long term remains to be seen.

Offchain Labs co-founder Steven Goldfeder posted on the X platform that as enterprise adoption accelerates, Arbitrum is ready to capture revenue. 10% of the fees collected by Robinhood Chain and all other Arbitrum L2s will flow into the Arbitrum ecosystem—8% will go into a treasury controlled by token holders, and 2% will be used to fund development.100% of the fees collected on Arbitrum One will be allocated to the Arbitrum treasury. According to previous reports, Robinhood Chain is an Ethereum Layer 2 network built on the Arbitrum tech stack.

According to official news, the privacy public chain Secret Network announced that it will migrate to the Arbitrum ecosystem, and the SCRT token will be converted to an ERC-20 token on Arbitrum. The migration is scheduled for a snapshot on September 1, 2026. Native SCRT and staked SCRT will be automatically migrated, but sSCRT, SCRT in contracts or liquidity pools, SCRT cross-chain to other chains, and IBC bridge tokens are not included in the migration scope and must be converted to native or staked status before September 1.After the migration, SCRT will still be a governance token, and the team proposes to reduce the inflation rate from 9% to 5%. After the migration is completed, SCRT Labs will stop maintaining Secret Network and open source all code. This proposal needs to be voted on by community governance. Coingecko data shows that the SCRT token is currently priced at $0.03965, with a 24-hour decline of 30.7%.

The on-chain spot exchange Rialto has announced its departure from stealth mode and is officially live. The platform is powered by PropAMM (proprietary automated market maker) and focuses on the integration of cryptocurrency and traditional finance, having collaborated closely with Robinhood Crypto, Offchain Labs, and Arbitrum over the past year.It is reported that Rialto is built on top of Robinhood Chain and Arbitrum, breaking the traditional market time constraints and supporting 24/7 trading of cryptocurrency spot, stock tokens, ETFs, commodities, and Pre-IPO assets. Users can self-custody equity tokens and use them directly as collateral for third-party lending. Currently, the platform is running its own PropAMM "Rivo Altus" to provide foundational liquidity, with over 90 Robinhood tokenized stocks and mainstream crypto assets already launched in the initial phase.

According to reports, LG Electronics has chosen the Ethereum Layer 2 network Arbitrum to develop a new blockchain to support advertising and media-related scenarios. Following the announcement, Arbitrum's native token ARB rose more than 5% in a single day. The network will be used for the delivery, purchase, sale, and management of digital advertising, and will record user interactions with advertising content.Arbitrum is developed by Offchain Labs and uses Optimistic Rollup technology, aiming to provide a faster and lower-cost transaction experience for Ethereum. This is not LG's first foray into blockchain. Previously, LG launched the enterprise-level blockchain Monachain through its IT services division LG CNS and developed the crypto wallet Wallypto; it also launched the Art Lab NFT marketplace, but that platform was shut down last year.

According to official news, the Arbitrum Foundation has initiated a new round of funding requests to the Arbitrum DAO, planning to obtain 16 million US dollars in stablecoins, 1,740 ETH, and 230 million ARB, with a total value of approximately 43.5 million US dollars.The funds raised this time will be specifically used for the foundation's operational work in 2027, covering areas such as technical infrastructure, ecosystem development, marketing promotion, and governance services. The ARB tokens requested in this application account for 3.7% of the total supply. In comparison, the Arbitrum DAO's total revenue for the year 2025 is approximately 23.49 million US dollars. Currently, this funding proposal is still in the community governance discussion stage.

According to on-chain data, the private key of the StakeDAO deployer was leaked on Arbitrum, and the attacker minted approximately 54.5 trillion vsdCRV, partially exchanging it for 43.7 ETH.

WasabiCard announced the official support for the Arbitrum network, further expanding its multi-chain payment infrastructure capabilities.

The DeFi lending protocol Alchemix announced the completion of its cross-chain infrastructure update. The old alUSD / alETH cross-chain bridge on Optimism and Arbitrum has officially been taken offline and replaced with a new cross-chain bridge compatible with v3 alchemist.Alchemix disclosed that it has synchronized the DVN (cross-chain transaction validation) configuration, maintaining a 2/3 multi-signature confirmation mechanism for cross-chain transactions, while introducing Deutsche Telekom as a validation service provider to enhance the reliability of the cross-chain validation infrastructure.

According to CoinDesk, the U.S. law firm Charles Gerstein has filed a petition in the Manhattan federal court, requesting an order for Tether to transfer over $344 million of frozen USDT to victims holding judgments against Iran for unpaid terrorism claims. These USDT were previously frozen by Tether after the U.S. Treasury Department's Office of Foreign Assets Control identified the related Tron wallets as belonging to the Islamic Revolutionary Guard Corps of Iran.The plaintiffs argue that since OFAC has designated the relevant wallets as owned by the Iranian Revolutionary Guard Corps, and Tether has frozen the related tokens, Tether can fully reissue an equivalent amount of USDT to a wallet controlled by the victims' attorney. This case is part of a broader legal strategy by Charles Gerstein aimed at leveraging the ability of crypto platforms to freeze and transfer digital assets to enforce terrorism-related judgments. Unlike the Arbitrum case involving North Korean-linked hacker funds, in this case, OFAC has clearly designated the relevant wallets as owned
