Arbitrum (ARB) — Onchain News & Whale Tracking

Arbitrum and Solana co-founders once again debate transaction costs: Steven emphasizes MEV protection, while Toly questions transaction fees and spreads.

Arbitrum co-founder Steven Goldfeder and Solana co-founder Toly have engaged in a debate over on-chain transaction fees, MEV protection, and the single sequencer model. Steven argued that surface-level fees alone should not be compared, noting that Arbitrum One and Robinhood Chain proactively prevent front-running and most malicious MEV, while some chains claiming lower fees carry higher MEV costs—including front-running targeting retail users. He stated he would rather pay clear, upfront fees than incur hidden losses from front-running, sandwich attacks, and other issues just to secure lower fees. Toly countered that Arbitrum currently has worse bid-ask spreads and higher fees. He explained that the 10% cut it takes from fees, when converted to basis points, already exceeds the sandwich attack loss rate—estimated to be roughly 10 times that rate—without even accounting for spread impacts. He emphasized: “A single sequencer that prioritizes maximizing shareholder value will never outcompete permissionless competition.”

Arbitrum co-founder clarifies that the remaining locked ARB held by investors and the team accounts for 7.7% of the total supply, with all of it to be unlocked in March next year.

Arbitrum co-founder Steven Goldfeder published a post noting that the market has a misunderstanding regarding ARB's supply, often counting tokens held by the DAO as part of locked supply. He explained that the unlock of tokens for ARB investors and team members is nearly complete, with all such tokens set to be fully unlocked by March next year. The portion of tokens yet to be unlocked currently accounts for approximately 7.7% of the total ARB supply. The Arbitrum DAO treasury currently holds 2.84 billion ARB, though these tokens are not traditional locked tokens—they are controlled by circulating token holders, and their transfer requires approval via a vote of other token holders.

Robinhood acts as the landlord, Ethereum as the security: An Arbitrum (ARB) Layer 2 has pushed mainnet settlement fees to nearly zero.

According to DefiLlama data, amid the meme token hype, Robinhood Chain generated $2.61 million in protocol revenue yesterday, with a 7-day total of $22.45 million. As an Ethereum Layer 2 (L2) built on Arbitrum Orbit, Robinhood Chain is required to allocate 10% of its net protocol revenue to the Arbitrum ecosystem. Over the past seven days, Arbitrum, which provides the underlying tech stack, has received around $2.48 million, split between its DAO and developer fund. Meanwhile, Uniswap, a decentralized exchange (DEX) on Robinhood, brought in $609,234 in protocol revenue yesterday, with a 7-day total of $3.36 million. Notably, Ethereum mainnet, as the settlement layer, saw negligible revenue: per growthepie data, Robinhood Chain paid just $1,270 in settlement fees to Ethereum mainnet yesterday, totaling $3,550 over the past seven days. This has sparked widespread debate in the crypto community. Prominent DeFi researcher Ignas pointed out that this structure—where platforms rake in massive profits while the settlement layer receives almost nothing—raises questions about whether this poses a problem for Ethereum. He noted that Ethereum may currently be using low fees to onboard TradFi players into its ecosystem, planning to increase charges once user migration costs become sufficiently high. If Ethereum’s official roadmap does include a strategy of first attracting a large number of L2s, then monetizing Layer 1 (L1) after switching costs rise, this could be positive for ETH, though such an approach is not currently outlined in Ethereum’s roadmap. Arbitrum co-founder Steven Goldfede responded that Robinhood chose Arbitrum to act as a landlord, not a tenant: controlling its own sequencer and keeping most fees for itself.

Arbitrum and Solana co-founders clash over Robinhood’s on-chain fee model: Solana’s Toly questions frontends should not profit from network congestion, while Arbitrum’s Steven pushes back, stating they aim to act as landlords rather than tenants.

Arbitrum founder Steven Goldfeder and Solana co-founder Toly have clashed over the fee model of Robinhood Chain. As an Ethereum layer-2 built on Arbitrum Orbit, Robinhood Chain allocates 10% of its net protocol revenue to the Arbitrum ecosystem: 8% to the DAO treasury and 2% to the development fund, with Robinhood retaining roughly 90% for itself. Recently, fees on Robinhood Chain have surged, with average per-transaction gas hitting around $0.4 at one point, and daily fees reaching millions of dollars—far higher than Solana’s typical ultra-low transaction costs. Solana co-founder Toly argues that the 10% split paid to Arbitrum is more than four times the equivalent transaction cost on Solana. If Robinhood Chain had been built on Solana, Robinhood could have offered users full gas waivers. Toly claims frontends should profit from their own apps, not from "network congestion-driven price hikes" on the underlying layer, calling Robinhood Chain’s model "brain dead." He asked Goldfeder: Why shouldn’t apps charge users directly? Does scaling and reducing congestion have to come at the cost of revenue? Arbitrum co-founder Steven Goldfeder countered that Toly’s view is "way off base." On Arbitrum, Robinhood keeps 90% of gas fees; on Solana, base layer fees go to validators or the network, so Robinhood would retain zero—meaning it would have to cover full gas waivers out of its own pocket. Goldfeder said Robinhood chose Arbitrum to act as a "landlord" rather than a "tenant," controlling its sequencer and keeping most fees for itself.

Arbitrum clarifies: Robinhood Chain did not suffer an outage yesterday, only experiencing batch submission delays.

Arbitrum issued a clarification stating that Robinhood Chain did not experience an outage today. Batch publishing delays occurred on Robinhood Chain due to Blob activity on the L1 market, but transactions initiated directly by users were not affected. Arbitrum noted that some infrastructure service providers relying on Robinhood Chain’s data streams faced brief performance issues due to the high volume of subscribed data sources. Robinhood Chain is currently operating normally.

Arbitrum DAO generated $6.19 million in revenue in the first half of the year, with Robinhood Chain emerging as a new revenue source.

An unaudited report released by the Arbitrum Foundation shows that Arbitrum DAO generated $6.19 million in revenue in the first half of 2026, with sources including Arbitrum One transaction fees, Timeboost sequencing priority auctions, scaling program licensing fees, and treasury management returns. The protocol’s gross profit margin exceeded 97%, and non-ARB treasury assets stood at $125 million as of the end of June. In H1 2026, Arbitrum processed a total of 478 million transactions, accounting for roughly 18% of its cumulative lifetime total of 2.7 billion transactions; monthly average stablecoin transfer volume surpassed $70 billion, and the number of stablecoin holders rose 40% to 10.5 million. Additionally, Arbitrum has deployed over 2,000 tokenized RWAs. Robinhood Chain, built on Arbitrum’s tech stack, launched its mainnet on July 1, contributing $360,000 in licensing fees to the DAO that month, making up 35% of its monthly revenue. On September 1, Robinhood Chain hit daily fees of $3.75 million, decentralized exchange (DEX) volume exceeding $1.5 billion, and total value locked (TVL) of over $750 million.

Robinhood Chain’s cumulative fee revenue has hit an all-time high, while Arbitrum has received approximately $1.3 million in cumulative revenue splits.

According to the latest data from arbdata, Robinhood Chain has generated a cumulative fee revenue of $13.05 million in just two months since its launch, hitting an all-time high. Calculated based on the 30-day average of its fee income, its annualized revenue stands at approximately $110 million. Based on the current cumulative revenue, around $1.3 million will directly flow to the Arbitrum ecosystem. Per the cooperation license agreement between the two parties, Robinhood Chain is required to remit 10% of the agreement’s net revenue back to the Arbitrum ecosystem: 8% goes to the Arbitrum DAO Treasury, and 2% is allocated to the Arbitrum Developer Guild.

10% of fees from Robinhood Chain and other Arbitrum Layer 2 (L2) networks will be allocated to the Arbitrum ecosystem, while 8% will flow to the token holders' treasury.

Offchain Labs co-founder Steven Goldfeder stated that 10% of fees generated by Robinhood Chain and other Arbitrum Layer 2 (L2) networks will flow to the Arbitrum ecosystem. Of that total, 8% will go to a treasury controlled by ARB token holders, while 2% will be earmarked for development funding. This mechanism gives the ARB token holder treasury a steady revenue stream, with the relevant funds potentially used for ecosystem grants, token buybacks, or staking rewards in the future. Should Robinhood Chain’s trading volume continue to grow, it could further strengthen the Arbitrum ecosystem’s revenue-generating capacity.

Privacy public blockchain Secret Network will migrate to Arbitrum.

According to official announcements, privacy public blockchain Secret Network has announced its migration to the Arbitrum ecosystem, with the SCRT token to be converted into an ERC-20 token on Arbitrum. The migration is scheduled to take a snapshot on September 1, 2026. Native SCRT and staked SCRT will be automatically migrated, but sSCRT, SCRT held in contracts or liquidity pools, SCRT bridged to other chains, and IBC-bridged tokens are not covered in the migration and must be converted to native or staked status before September 1. Post-migration, SCRT will remain a governance token, with the team proposing to lower its inflation rate from 9% to 5%. Upon completion of the migration, SCRT Labs will cease maintenance of Secret Network and open-source all its code, and the proposal is subject to a community governance vote. Separately, data from Coingecko shows SCRT is currently trading at $0.03965, down 30.7% over the past 24 hours.

LG Electronics to Launch Advertising Business Blockchain on Arbitrum, ARB Surges Over 5% Within a Day

June 12 update: South Korea’s LG Electronics has selected Arbitrum as the underlying technology to launch a new blockchain network tailored exclusively for the advertising and media industry. The platform will handle ad placement, purchasing, selling, and management, plus track user interaction data related to ads. It will also serve as an advertising inventory sharing database to boost transparency and efficiency across the sector. This marks another major step in LG’s ongoing blockchain efforts. Previous projects from the company include enterprise-level Monachain, the Wallypto crypto wallet, and an operated NFT marketplace. The new chain—built by LG’s Blockchain Research Lab—already ran a pilot test with a Japanese advertising firm. It currently has no official name, and LG plans to assess its commercial potential later this year. Per HTX market data, ARB surged more than 5% in response to this announcement.

Arbitrum Foundation Proposal Seeks Around $43.5 Million Funding for Operations Through 2027

On May 29, the Arbitrum Foundation published a proposal seeking continued funding through 2027, totaling roughly $43.5 million. The request breaks down to $16 million in RWA and stablecoins, plus 1,740 ETH and 230 million ARB. For 2027 alone, the foundation projects total operating expenses will hit approximately $27.6 million and 2.449 billion ARB—with 54% allocated to technical maintenance, and the rest covering administrative management and ecosystem development. Notably, the proposed funding ask falls below the foundation’s pre-set budget ceiling; any gap between the request and total 2027 costs will be covered via its existing balance sheet. On-chain voting on the proposal is scheduled to take place on June 8.

Arbitrum DAO Vote Passes Proposal to "Approve Release of Frozen ETH"

On May 8, the Arbitrum DAO approved the "Unfreezing Frozen ETH" proposal with a 90.96% approval rate. The proposal calls for Arbitrum governance to greenlight the release of 30,765.67 ETH—frozen by the Arbitrum Security Council on April 21—and transfer the funds to a 3-of-4 multisig wallet jointly controlled by Aave Labs, KelpDAO, EtherFi, and Certora. This address will be used exclusively for recovery efforts involving the unfrozen ETH.

Aave Proposes Emergency Motion to Reverse Asset Freeze Notice on Arbitrum DAO

May 4 — Official sources confirm Aave LLC has filed an emergency motion to overturn an asset freeze notice issued to the Arbitrum DAO on May 1, 2026. The notice sought to freeze roughly $71 million in ETH tied to victims of the April 18, 2026 attack. Aave noted that mere theft does not convey legal ownership of stolen assets — a well-established legal principle. The recovered funds are earmarked for return to users who incurred losses in the April 18 attack; freezing these assets directly harms the very users the recovery effort is intended to protect. Aave has requested the court schedule an emergency hearing to temporarily lift the freeze order and continues collaborating with the Arbitrum community and DeFi United to compensate affected users.

New York Federal Court Orders Arbitrum DAO to Freeze $71 million ETH Linked to North Korean Hackers, Potentially for Compensation to Terror Attack Victims

On May 3, the U.S. District Court for the Southern District of New York issued a restraining order against Arbitrum DAO, barring it from transferring approximately $71 million worth of ETH assets frozen following the KelpDAO hack. The plaintiff is seeking to use these assets to enforce an unpaid judgment related to North Korea’s history of terrorism, kidnappings, and other cases. Court filings show the plaintiff has applied to serve legal notice on Arbitrum DAO via alternative methods and classifies the entity as a liable "partnership organization." The court also noted Arbitrum DAO has a Security Council governed by ARB token holders, with authority to act in emergencies. If members decline to cooperate, they could face legal consequences including contempt of court. Market participants view the case as a potential landmark example of the U.S. judicial system directly impacting DAO governance structures, again underscoring compliance pressures on DeFi protocols within real-wo

Arbitrum DAO has commenced voting on the release of frozen Ethereum funds

Arbitrum DAO launched a vote on Monday, May 1, regarding the release of stolen ETH frozen by the protocol following the Kelp DAO hack. The proposal calls for establishing a multi-signature (multi-sig) address with signers including Aave Labs, KelpDAO, Certora, and EtherFi. This address will be used exclusively for recovery efforts once it receives the frozen ETH held by Arbitrum. As of now, the proposal holds a 100% approval rate. Voting is scheduled to conclude on May 8 at 2:54 a.m. Beijing Time.

Arbitrum Freezes $71 Million in Dispute: Can Decentralization Still Face “Human Intervention”?

On April 24, following the KelpDAO exploit, the Arbitrum Security Council stepped in to freeze over 30,000 ETH (roughly $71 million), successfully preventing the stolen funds from being fully withdrawn. The move has, however, ignited a heated debate over the "decentralization boundary." The operation was carried out by a 12-member security council elected by token holders, who used their special authority to move the attacker’s funds to a "null address"—effectively freezing the assets. Supporters argue the intervention bought critical time for the industry, blocked further money laundering, and served as a necessary "security-first" mechanism. Critics, though, note the incident reveals how even in a so-called decentralized network, key moments can be swayed by a small group. This challenges the core principle of "code is law" and raises concerns about potential future abuses. In response, Arbitrum stated the mechanism was designed to be transparent and community-approved, acti

Aave: The rsETH Reserve has been paused on the Ethereum mainnet, Arbitrum, and other networks to facilitate fund recovery

April 23 — Aave published an update on the rsETH incident: "The rsETH reserve has been suspended across Ethereum mainnet, Arbitrum, Base, Mantle, and Linea. This step aligns with the fund recovery plan aimed at reclaiming as much of the funds as possible. The community will be kept informed of progress as the follow-up process continues."

KelpDAO Attacker Transfers Part of Stolen Funds: Cross-Chain Swaps to Arbitrum, Converts to USDT, and Flows into the Tron Ecosystem

April 22 — PeckShield monitoring shows the KelpDAO attacker has begun transferring stolen assets: they’ve sent some stolen ETH from the Ethereum mainnet to Arbitrum via Across Protocol, swapped it for USDT, then routed it to the TRON DAO ecosystem via LayerZero. This trajectory indicates the attacker is diversifying and laundering funds through multi-chain bridges and stablecoin conversions; further tracking of the fund flow remains ongoing.

Analysis: Arbitrum Freezes KelpDAO Hacker's ETH in System-Level Transaction, Injected via ArbOS by Security Council

On April 21st, Dragonfly General Partner Haseeb Qureshi published an analysis of the Arbitrum Security Council’s freeze of 30,766 ETH belonging to the KelpDAO hacker. Key details from the analysis: - The transaction was an **ArbitrumUnsignedTxType** (EIP-2718 type 0x65/101) — a system-level transaction that regular EOAs cannot sign, and only the Arbitrum Security Council can inject via ArbOS. - This action did **not** involve chain rollbacks or historical state rewrites; it was a *state-level clawback*: the hacker’s private key still works for signing transactions, but the ETH in their address was moved by the chain itself. - The operation showcased the Security Council’s authority in the "catastrophic emergency" scenario outlined in Arbitrum’s progressive decentralization documentation.

Arbitrum Security Council Freezes KelpDAO Hacker's 30,766 ETH

On April 21, the Arbitrum Security Council announced it had taken emergency action to recover 30,766 ETH from an Arbitrum One address tied to the KelpDAO exploit. With law enforcement support, the Council identified the attacker’s identity—prioritizing the security and integrity of the Arbitrum community while ensuring no impact to users or applications. After extensive technical investigation and review, the Council deployed a solution to move the funds to a secure intermediate frozen wallet without altering any other chain state or affecting users. As of 11:26 PM Eastern Time on April 20, the transfer was completed successfully. The original funds-holding address can no longer access the assets; only Arbitrum custodians may take further action to transfer the funds, a process to be coordinated with all relevant parties.

Morpho: Pause of MORPHO's OFT Cross-Chain Bridge on Arbitrum Pending Root Cause Analysis of rsETH Incident

Vitalik Questions L2 Scaling Path, Arbitrum, Optimism, and Base Respond Collectively on "Dehomogenization" Direction

On February 4, Ethereum co-founder Vitalik Buterin recently said the original idea of Layer 2 as Ethereum’s primary scaling solution is “no longer tenable,” calling for Layer 2 networks to evolve toward a more specialized direction. The statement quickly drew responses from major L2 teams including Arbitrum, Optimism, Base, and others. Vitalik noted many Layer 2 solutions still rely on multi-sig bridges and haven’t fully inherited Ethereum’s security. Meanwhile, with higher Gas limits and progress in native Rollup solutions, Ethereum’s mainnet throughput is rising—so Layer 2’s positioning needs to be reconsidered. Optimism Foundation co-founder Karl Floersch expressed support for building a modular Layer 2 covering the “entire decentralization spectrum,” but acknowledged current challenges: long withdrawal periods, immature Stage 2 proof mechanisms, and insufficient cross-chain tools. Arbitrum dev team Offchain Labs co-founder Steven Goldfeder emphasized scaling remains Layer

Arbitrum Co-Founder Backtracks? Post States "Arbitrum is not Ethereum" in Response to Vitalik's Roadmap Controversy

**Key Update: Off Chain Labs Co-Founder Clarifies Arbitrum-Ethereum Relationship Amid Vitalik’s Recent Comments** On February 4th, Steven Goldfeder—co-founder of Off Chain Labs (the team behind layer-2 network Arbitrum)—took to social media to outline core points about Arbitrum’s ties to Ethereum: 1. **Arbitrum ≠ Ethereum**: He stressed Arbitrum and Ethereum are close allies with a five-year symbiotic relationship, not the same entity. 2. **L1-L2 Alignment**: Goldfeder pushed back on the idea that a scaled layer-1 (L1) conflicts with a thriving layer-2 (L2) ecosystem, noting no L2 team he’s aware of opposes L1 scaling. Off Chain Labs actively supports Ethereum’s L1 development, he added, by acquiring and continuously funding Prysm to ensure it has sufficient resources for ongoing work. 3. **L2’s Institutional Edge**: While agreeing with Vitalik’s take that “The Rollup story evolves with time,” Goldfeder argued Ethereum’s best bet for winning large institutions remains L2s. “E
