Arbitrum One secures $12.31 billion in bridged and minted assets, second among Ethereum rollups behind Base Chain’s $14.31 billion. The network processed 478 million transactions in the first half of 2026, taking its lifetime total to 2.7 billion. Income of $6.19 million accrued to the ArbitrumDAO across four lines during the half, at a collective gross margin on protocol revenue above 97%. Those Arbitrum statistics come from the Foundation’s own half-year disclosures, the L2BEAT dashboard, and onchain fee data.
Those three numbers describe a network that has stopped competing purely on size and started behaving like a business with a profit and loss statement. The Arbitrum statistics below cover value secured, token supply, throughput cost, governance spending, and the 2026 protocol upgrades.

Arbitrum Statistics: Value Secured and Transaction Volume
Independent tracking puts Arbitrum One near the top of the rollup field on value secured. The Arbitrum Foundation’s own half-year report supplies the transaction and output figures.
- Arbitrum One’s $12.31 billion in total value secured splits into $3.51 billion canonically bridged from Ethereum, $4.65 billion natively minted, and $4.14 billion bridged in through third-party routes.
- That ranks it second on L2BEAT’s leaderboard, ahead of OP Mainnet at $1.64 billion.
- Ecosystem GDP, the Foundation’s measure of onchain economic output, reached $206 million for the half and $1.7 billion cumulatively.
- Average monthly stablecoin transfer volume exceeded $70 billion across the period.
- DefiLlama records $169,255,375 in Arbitrum chain fees since launch.
By the numbers: Arbitrum processed 478 million transactions in the six months to 30 June 2026, lifting its lifetime total to 2.7 billion, while ecosystem output reached $206 million for the half and $1.7 billion since launch. Those four figures come from the Arbitrum Foundation’s own half-year disclosure.
| Metric | Latest figure | Period |
|---|---|---|
| Total value secured | $12.31 billion | 4 September 2026 |
| Canonically bridged | $3.51 billion | 4 September 2026 |
| Natively minted | $4.65 billion | 4 September 2026 |
| Externally bridged | $4.14 billion | 4 September 2026 |
| Transactions processed | 478 million | H1 2026 |
| Lifetime transactions | 2.7 billion | Since launch |
| Ecosystem GDP | $206 million | H1 2026 |
| Cumulative ecosystem GDP | $1.7 billion | Since launch |
| Average monthly stablecoin transfers | Over $70 billion | H1 2026 |

Composition matters more than the headline here. A chain whose value is mostly native mints depends on its own issuers staying put. Canonically bridged value tracks something different: how much Ethereum capital chose to cross.
Why it matters: The same period produced $6.19 million of ArbitrumDAO income across four separate lines, at a collective gross margin above 97%, up from more than 90% for full-year 2025. Most coverage of the network reports a single revenue number, or none at all, and misses the composition entirely.
Arbitrum ended the half ranked first by tokenised real-world asset deployments, according to RWA.xyz, with more than 2,000 assets deployed. That tokenisation base runs on the same smart contracts infrastructure carrying the network’s stablecoins.
ARB Token Supply and the Unlock Schedule
Two published supply figures describe ARB, and they differ because unlocked and circulating measure different things.
- ARB traded at $0.131482 on 4 September 2026, with a market capitalisation of $877,287,701 and a fully diluted valuation of $1,313,683,327.
- CoinGecko records 6,678,075,931 tokens circulating against a maximum supply of 10,000,000,000. That is 67% of the cap.
- Approximately 9.23 billion ARB, or 92.3% of total supply, was unlocked or held in the ArbitrumDAO treasury as of 17 August 2026.
- The remaining 0.77 billion ARB, 7.7% of total supply, is the balance of the original vesting schedule, with the final vest arriving in March 2027.
- ARB set an all-time low of $0.07048 on 26 June 2026, against an all-time high of $2.39 on 12 January 2024.
| Market metric | Value |
|---|---|
| Price | $0.131482 |
| Market capitalisation | $877,287,701 |
| Fully diluted valuation | $1,313,683,327 |
| 24-hour trading volume | $321,429,899 |
| Market capitalisation rank | 78 |
| All-time high | $2.39 on 12 January 2024 |
| All-time low | $0.07048 on 26 June 2026 |
Source: CoinGecko API, read 4 September 2026
Both figures are correct, and the gap between them is the single most misread number about ARB. Unlocked means no longer subject to vesting. Circulating means held by somebody other than the DAO. The difference between the two published figures is 2.55 billion ARB.

Where ArbitrumDAO Income Comes From
The Foundation discloses four separate income lines rather than a single revenue number, and Robinhood Chain only started contributing to the licence-fee line in July.
- Income of $6.19 million accrued to the ArbitrumDAO from four lines during the half: Arbitrum One transaction fees, Timeboost, Arbitrum Expansion Program (AEP) licence fees and treasury income.
- The collective gross margin on protocol revenue exceeded 97%, up from more than 90% for full-year 2025.
- In July, AEP licence fees of $360,000 were 35% of ArbitrumDAO income, the first month with Robinhood Chain on mainnet.
- Arbitrum’s chain fees came to $11,375,138 over the trailing year. On a 35% share, rounded to two figures, implied total July income was about $1.0 million.
| Income line | What it charges for | Latest disclosed figure |
|---|---|---|
| Arbitrum One transaction fees | Gas paid by users on the rollup | Included in the $6.19 million half-year total |
| Timeboost | Auctioned priority access to the sequencer | Included in the $6.19 million half-year total |
| Arbitrum Expansion Program licence fees | 10% of net protocol revenue from chains settling elsewhere | $360,000 in July 2026 |
| Treasury income | Returns on DAO-held assets | Included in the $6.19 million half-year total |
Source: Arbitrum Foundation Bi-Annual Progress Update H1 2026, September 2026
A margin that high is a property of the cost structure, not a management achievement. Among the 2026 Arbitrum statistics, it is also the least quoted. Sequencing costs are near-fixed, so every marginal transaction drops almost straight through.
The other three lines contributed roughly $0.67 million between them on the same rounding. Read against the DAO treasury moves that token holders vote on, operating income is modest next to the balance sheet it funds. That gap is the structural tension in every large DAO running a real protocol.
Robinhood Chain and the Expansion Program
A chain built on Arbitrum’s stack, live for two months, now out-earns Arbitrum One on raw fees.
- Robinhood Chain is a dedicated Arbitrum chain built by Robinhood and settling to Ethereum. It launched its public testnet in February 2026 and processed more than 200 million transactions before its mainnet launch on 1 July.
- Chains that settle outside Arbitrum One and Arbitrum Nova return 10% of net protocol revenue to the Arbitrum ecosystem under the Expansion Program.
- Robinhood Chain collected $4,591,743 in fees over 24 hours, $19,230,450 over 30 days, and $23,038,556 since it went live.
- Arbitrum booked $375,469 in chain fees over the same 30-day window. The tenant chain out-earned its own technology stack by a factor of 51.
That headline number flatters Arbitrum less than it first appears. Arbitrum does not collect Robinhood Chain’s fees, only a 10% licence share on net protocol revenue.
Robinhood Chain follows Robinhood’s issuance of tokenised stocks and ETFs on Arbitrum One in June 2025. PayPal’s PYUSD peaked at $475 million on Arbitrum in the first quarter. Distribution of that kind moves the way crypto exchange market share does, concentrating volume where the largest consumer front-end sits.
Throughput and What Ethereum Data Costs
Settlement is close to free on a per-operation basis, which is why the fee base looks thin next to the value secured.
- Arbitrum One ran 18.86 user operations per second in the past day, or 1.62 million operations, against a record 109.13 set on 5 February 2026.
- The chain paid Ethereum an average of $0.000237 per user operation and $557.04 a day, posting 122.75 GiB of data over the year.
- Transaction data submission ran every 2 minutes and state updates every 59 minutes, with 100% normal uptime across the past 30 days.
- Arbitrum chains default to a 250-millisecond block time with a 100-millisecond optional floor, and a default withdrawal time of 6.4 days unless fast withdrawals are enabled.
| Operating metric | Value | Window |
|---|---|---|
| User operations per second | 18.86 | Past day |
| Operations count | 1.62 million | Past day |
| Record user operations per second | 109.13 | 5 February 2026 |
| Ethereum data cost per user operation | $0.000237 | Trailing year |
| Ethereum data cost per day | $557.04 | Trailing year |
| Data posted to Ethereum | 122.75 GiB | Trailing year |
| Transaction data submission interval | 2 minutes | Past 30 days |
| State update interval | 59 minutes | Past 30 days |

Set the $557.04 daily settlement bill against the chain fees above, and the shape of the business is clear. Settlement is close to free, so revenue tracks demand rather than efficiency.
Those settings put Arbitrum at the fast end of the L2 field while keeping settlement anchored to Ethereum.
Stylus, Timeboost and the ArbOS 61 Upgrade
Three protocol changes define the current stack, and each one targets a different bottleneck.
- Stylus adds a second, coequal WASM virtual machine to the EVM, letting contracts be written in Rust, C, and C++ while remaining interoperable with Solidity.
- Timeboost auctions control of an express lane in 60-second rounds, applying a 200-millisecond artificial delay to transactions outside the lane while the default block time stays at 250 milliseconds.
- The express lane controller has no right to reorder transactions and no guarantee of top-of-block position, and the transaction mempool stays private.
- ArbOS 61 “Elara” raises the Stylus contract code size limit to 96 KB and adds a BaseFeeManager contract managing the minimum L2 base fee.
- It also ships an Alternative Data Availability (AltDA) Layer API and optional compliance transaction filtering, both of which stay disabled on Arbitrum One and Nova and are there for the convenience of other Arbitrum chains.
| Protocol parameter | Value |
|---|---|
| Default block time | 250 milliseconds |
| Optional block time floor | 100 milliseconds |
| Timeboost round duration | 60 seconds |
| Non-express-lane delay | 200 milliseconds |
| Stylus contract code size limit | 96 KB |
| Default withdrawal finality | 6.4 days |

The mechanics are set out in the project’s Stylus documentation, and the full ordering policy in Arbitrum’s Timeboost specification.
A newer primitive, the Machine Payments Protocol, settles agent payments from an offchain EIP-712 signature. The payer never broadcasts a transaction or pays gas, and the merchant covers it. Read together, these three point to one way: Arbitrum is optimising for workloads that are not human beings clicking buttons.
DAO Treasury and Governance Spending
Token holders, not the Foundation, direct the treasury, and the spending discipline is disclosed alongside the income.
- The DAO held $125 million in non-native treasury assets, excluding ARB, at 30 June 2026.
- ARB holders govern the ArbitrumDAO and direct its assets and income.
- In the six months to 30 June, less than $200,000 of the Foundation’s ecosystem grants were issued upfront without milestone conditions.
- The ArbitrumDAO earmarked 80 million ARB across four seasons of the DeFi Renaissance Incentive Program when it approved the programme in June 2025, worth over $40 million at the time, with Season One budgeted at up to 24 million ARB.
- The DAO announced Season One on 3 September 2025 across lending and borrowing protocols including Aave, Morpho, Fluid, Euler, Dolomite and Silo, with each season set to last approximately four to five months.
| Treasury or programme item | Figure | As of |
|---|---|---|
| Non-ARB treasury assets | $125 million | 30 June 2026 |
| Grants issued upfront without milestones | Less than $200,000 | Six months to 30 June 2026 |
| DeFi Renaissance Incentive Program budget | 80 million ARB | Approved June 2025, four seasons |
| DRIP Season One budget | Up to 24 million ARB | Announced 3 September 2025 |
| Unlocked or DAO-held ARB | 9.23 billion | 17 August 2026 |
Source: Arbitrum Foundation Bi-Annual Progress Update H1 2026 and ArbitrumDAO announcements, 2025 to 2026
Worth noting: Releasing grant money against delivery rather than upfront limits the market impact of ecosystem spending, which matters when the funding asset is the same token that governs the treasury. Less than $200,000 of Foundation ecosystem grants went out upfront without milestone conditions in the six months to 30 June.
Programmes of that size shape where liquidity sits across DeFi, because incentive budgets move deposits faster than product quality does.
How Arbitrum Compares With Rival Layer-2 Networks
Both measures place Arbitrum immediately behind Base. They disagree on the size of the gap, a methodology artefact rather than a data error.
- Base Chain leads L2BEAT’s rollup leaderboard at $14.31 billion in total value secured, ahead of Arbitrum One at $12.31 billion, OP Mainnet at $1.64 billion, and Mantle at $1.45 billion.
- On DeFi total value locked, a different measure entirely, Arbitrum held $1,403,237,468 against Base’s $5,608,163,090 and Robinhood Chain’s $857,074,126. Base carried 4.0 times Arbitrum’s DeFi deposits.
Two different things are being counted. Value secured covers everything bridged or minted on the chain, while DeFi total value locked covers only what sits inside protocols.
Trading venues built on the network show the same split. That is why DEXs and the wallet activity tracked in MetaMask wallet data rarely move in step with headline value secured.
Security Model and the Stage 1 Rating
Arbitrum One clears L2BEAT’s Stage 1 bar, which describes escape hatches rather than the absence of trusted parties.
- L2BEAT rates Arbitrum One a Stage 1 optimistic rollup that passes the walkaway test, so users can exit in the presence of malicious operators even if the Security Council disappears.
- All of the data needed for proof construction is published on Ethereum L1, and interactive fraud proofs let watchers challenge an incorrect state.
- The Security Council recovered approximately 30,766 ETH from a KelpDAO exploiter on 21 April 2026.
| Security parameter | Status |
|---|---|
| Decentralisation stage | Stage 1 optimistic rollup |
| Walkaway test | Passed |
| Data availability | Onchain, published to Ethereum L1 |
| State validation | Interactive fraud proofs |
| Forced inclusion delay if the sequencer fails | Up to 1 day |
| Uptime anomalies in the past 30 days | None |
Source: L2BEAT Arbitrum One risk assessment, 4 September 2026
Emergency upgrade risk: In the event of a sequencer failure, users can force transactions into the chain by sending them to L1, but there can be up to a 1-day delay on that operation.
April’s recovery is the clearest available evidence of what Stage 1 means in practice. A council capable of clawing back stolen funds is also, by construction, a council capable of acting without user consent.
Is Arbitrum part of Ethereum?
Arbitrum is not part of Ethereum, but it settles to it. Arbitrum One is a Stage 1 optimistic rollup whose proof-construction data is published entirely on Ethereum L1. Users can force transactions through L1 if the sequencer fails.
Its execution layer runs Arbitrum Nitro, where EVM contracts behave exactly as they would on Ethereum. Ethereum supplies settlement and data availability; Arbitrum provides execution.
Is Robinhood using Arbitrum?
Robinhood uses Arbitrum in two separate ways. Robinhood issued tokenised stocks and ETFs on Arbitrum One in June 2025. It then built Robinhood Chain, a dedicated Arbitrum chain settling to Ethereum, which reached mainnet on 1 July 2026. That chain has collected $23,038,556 in fees since going live.
Chains settling outside Arbitrum One and Arbitrum Nova return 10% of net protocol revenue to the Arbitrum ecosystem under the Expansion Program.
Conclusion
Arbitrum One ends the period second among Ethereum rollups, with $12.31 billion in total value secured. Set against that balance sheet, the DAO’s disclosed income of $6.19 million for the half carries a gross margin above 97%. What the 2026 Arbitrum statistics record is not the size of either number. A third party has arrived in the accounts: chains Arbitrum does not operate.
Watch the Expansion Program line through the second half. It was 35% of July income, the first month with Robinhood Chain on mainnet. The ARB vesting schedule also closes out in March 2027, and both variables land on the treasury token holders’ vote to spend.
