Arbitrum Total Value Secured Statistics

Arbitrum One’s headline metric is its Total Value Secured (TVS), the L2Beat composite of assets canonically bridged from Ethereum, natively minted on the L2, and externally bridged via third-party routes. TVS reached $15.57 billion on May 17, 2026, up 2.88% day-over-day, with the rollup keeping its top spot since the metric started tracking institutional flows.

• Arbitrum One TVS reached $15.57 billion, up 2.88% day-over-day.
• Canonically bridged assets on Arbitrum One totaled $3.27 billion, with a past-day change of 7.13%.
• Natively minted tokens on Arbitrum One reached $4.73 billion, with a past-day change of 4.32%.
• Externally bridged value reached $7.56 billion on Arbitrum One, with a past-day change of 0.04%.
• L2Beat flags 48.5% of Arbitrum One TVS as carrying additional trust assumptions.
• The 48.5% trust-flag share gives readers a single ratio to weigh against the headline number. TVS without that context overstates the security of half the assets.

Arbitrum vs Other Layer-2 Rollups

Side-by-side, Arbitrum’s TVS lead over the rest of the L2 rollup field is asymmetric. Base is closing in while OP Mainnet has fallen far behind, a dispersion most single-chain coverage misses. The top 6 L2 rollups by TVS span proof-system families (Optimistic, Validity) and risk profiles, with Lighter and Starknet representing the validity-proof challenger tier.

• Arbitrum One sits #1 at $15.57 billion TVS with 14.66 past-day UOPS, change of +1.56%.
• Base Chain ranks #2 at $12.11 billion TVS with 81.65 past-day UOPS, a change of +8.20%.
• OP Mainnet ranks #3 at $1.57 billion TVS with 14.95 past-day UOPS, change of +18.8%.
• Mantle ranks #4 at $1.44 billion TVS, running Validity SP1 Hypercube proofs with 0.48 past-day UOPS.
• Lighter Exchange ranks #5 at $670.97 million TVS with 532.30 past-day UOPS on a validity-proof stack.
• Starknet ranks #6 at $632.47 million TVS with Validity Two proofs.
• Our 80+ statistics pages tell a story price charts don’t. Base’s 81.65 UOPS versus Arbitrum’s 14.66 shows where transaction demand is heading, even when the TVS leaderboard says otherwise.

Source: L2Beat

By the numbers: Per L2Beat, the top 3 Ethereum rollups now account for $29.25 billion in combined TVS, with Arbitrum’s $15.57 billion representing more than half of that pool. Arbitrum holds roughly 53% of the top-3 rollup TVS pool today.

Arbitrum DeFi TVL Statistics

DefiLlama’s protocol TVL on Arbitrum measures a narrower slice than L2Beat, only assets deployed inside tracked DeFi smart contracts on the chain, excluding bridged inventory sitting idle. Protocol TVL on Arbitrum reached $1.56 billion on May 17, 2026, with the chain ID 42161 carrying the ARB token symbol, reflecting the working capital of Ethereum‘s largest L2 DeFi market.

• Arbitrum chain DeFi TVL reached $1,562,538,550 (approximately $1.56 billion) on DefiLlama.
• Ethereum mainnet DeFi TVL stood at $44.30 billion on the same DefiLlama snapshot.
• OP Mainnet DeFi TVL stood at $347.87 million on the same snapshot.
• Arbitrum’s DeFi TVL is roughly 3.5% of Ethereum mainnet’s DeFi TVL.
• Arbitrum’s DeFi TVL is approximately 4.5 times OP Mainnet’s DeFi TVL.
• The gap between L2Beat TVS ($15.57 billion) and DefiLlama DeFi TVL ($1.56 billion) is the cleanest signal of how much value sits parked versus actively earning yield on Arbitrum.

Arbitrum Daily Activity Statistics

User Operations Per Second (UOPS) is the L2Beat metric that captures actual on-chain demand on Arbitrum One, separate from raw transaction count. Past-day UOPS on Arbitrum One sat at 14.66 with a daily change of +1.56%, a measured pace versus the validity-rollup challengers but materially higher than the bottom of the rollup field.

• Arbitrum One’s past-day UOPS was 14.66 per the L2Beat leaderboard.
• Past-day UOPS change came in at +1.56% day-over-day.
• Base Chain’s past-day UOPS of 81.65 sat well above Arbitrum’s 14.66 on the same L2Beat snapshot.
• OP Mainnet’s past-day UOPS of 14.95 ran neck-and-neck with Arbitrum.
• Activity volume tells a different story than TVS. Arbitrum leads in dollars secured but trails Base on operations per second, suggesting different user mixes between the two rollups.

Source: L2Beat

How does Arbitrum’s daily activity compare to Ethereum mainnet?

Arbitrum’s user operations sit at a fraction of Ethereum mainnet’s raw transaction throughput, but the comparison flatters Arbitrum because each L2 user operation can settle multiple actions in a batched proof. Arbitrum One’s past-day UOPS sat at 14.66 on the L2Beat leaderboard, shifting the relevant comparison from raw transaction count to L2-throughput-per-L1-data-byte.

Arbitrum Number of dApps and Protocols

The dApp count on Arbitrum spans DeFi protocols, perpetual exchanges, lending markets, NFT venues, and the broader DeFi ecosystem. With Arbitrum tracked as a top-tier chain on DefiLlama (chainId 42161) and held against Ethereum and OP Mainnet, the protocol mix includes the chains’ anchor lending and DEX venues plus an expanding RWA and perps layer.

• Arbitrum is tracked at the chain level by DefiLlama with chainId 42161 and the ARB token symbol.
• Our coverage of smart contracts shows Arbitrum sitting in the top tier of EVM-compatible chains for protocol deployment, with the Orbit stack expanding the surface further.
• Arbitrum’s $1,562,538,550 chain-level DeFi TVL is the protocol-tracked total carried under chainId 42161 on DefiLlama.
• The dApp count is less informative than the TVL-weighted breakdown; three protocols often hold the majority of the chain’s value, with the long tail providing optionality rather than scale.

How many dApps are on Arbitrum?

DefiLlama tracks Arbitrum at the chain level, and the chain’s protocol surface spans hundreds of distinct deployments when measured at the contract level, with the working-capital concentration sitting in roughly the top venues. Per DefiLlama’s chain-level tracking, Arbitrum carries chainId 42161 and the ARB token symbol, with the protocol count itself less informative than the per-protocol TVL distribution.

Arbitrum DAO Treasury and Governance Statistics

The Arbitrum DAO governs both Arbitrum Core (protocol-level changes) and the Arbitrum Treasury (capital allocation), with proposals indexed on Tally and voted using the ARB token. Tally indexes the Arbitrum DAO with its ERC20 governance token, 10 billion total supply, and the recent proposal slate shows active treasury deployment plus protocol-upgrade governance.

• Arbitrum’s governance token is an ERC20 with 10 billion total supply.
• Tally separates Arbitrum Core (protocol-level) proposals from Arbitrum Treasury (capital allocation) proposals in its index.
• Treasury-class proposals on Tally include direct ETH transfers and stablecoin movements out of the DAO Treasury.
• The “Transfer 6,000 ETH and Idle Stablecoins from the Treasury” proposal was executed on April 20, 2026, with 193.92 million For votes from 2,523 addresses.
• The “Transfer 8,500 ETH from the Treasury to ATMC’s ETH Treasury” proposal executed on October 13, 2025, with 166.41 million For votes from 2,470 addresses.
• The Arbitrum Security Council Election was completed on Tally during the most recent governance window.
• The pattern we’ve documented across 18 regulatory events holds for DAO governance too: capital decisions follow protocol-clarity moments. Arbitrum’s October 2025 ATMC transfer came months after the August 2025 cost-cap removal that created treasury optionality.

How big is the Arbitrum DAO treasury?

The Arbitrum DAO controls a treasury whose recent Tally-indexed proposals include capital deployments of 8,500 ETH (October 2025) and 6,000 ETH plus idle stablecoins (April 2026). The Tally-indexed proposal history confirms an active treasury making material capital moves, rather than a passive token holding.

ARB Token Statistics

The ARB token sits at a moment of supply-pressure transition, a recent all-time low in early 2026 sat below recent ranges while the chain’s TVS continued to climb. ARB traded with a market capitalization of $783,386,957 at a price near $0.12, with a 7-day range from $0.1184 to $0.1454, and the stablecoins and DeFi flows the rollup secures provide the demand backdrop.

• ARB market capitalization sat at $783,386,957 with the token priced in the $0.1185, $0.1222 24-hour range.
• ARB Mkt Cap / FDV ratio was 0.62, meaning the current market cap reflected 62% of fully diluted valuation.
• The all-time high of $2.39 was set on January 12, 2024 (over 2 years ago at the time of capture).
• The all-time low of $0.08709 was set on March 29, 2026 (about 2 months ago at the time of capture).
• The most active trading pair, ARB/USDT, had $3,533,550 in 24-hour trading volume.
• ARB’s price fell to $0.08709 on March 29, 2026, even while TVS climbed past $15 billion, the kind of price-versus-adoption decoupling our 80+ statistics pages document across crypto cycles. Adoption metrics matter more than price for long-term assessment.

ARB Token Supply and Distribution Statistics

ARB launched with a max supply set at issuance and a vesting schedule that releases tokens over multi-year periods to the foundation, contributors, investors, and the DAO treasury. The token’s maximum supply is 10,000,000,000, with an estimated circulating supply at 6,150,718,438, leaving roughly 38% of the total value tied to tokens not yet in market.

• Max supply of ARB is 10,000,000,000 tokens (10 billion).
• The estimated circulating supply is 6,150,718,438 tokens.
• Outstanding supply on the CoinGecko snapshot stood at 6,435,020,283 tokens.
• Circulating supply represents approximately 61.5% of the max supply.
• The non-circulating share of token value sits near 38% based on the 0.62 Mkt Cap/FDV ratio.
• The 0.62 Mkt Cap/FDV ratio is the price-pressure variable most ARB coverage glosses over; every unlock cohort entering circulation has to be absorbed by demand without depressing price.

What is the ARB token total supply?

ARB has a hard-coded max supply of 10,000,000,000 tokens, with an estimated circulating supply of 6,150,718,438 as of the latest CoinGecko snapshot. The remaining tokens vest over multi-year schedules to the DAO treasury, foundation, contributors, and investors.

Arbitrum Transaction Fees and Cost Statistics

Arbitrum’s fee economics changed materially with the December 2025 governance vote that activated ArbOS 51 (Dia) and updated gas pricing, replacing earlier cost-cap mechanics with a recalibrated fee surface. The Constitutional AIP to “Activate ArbOS 51 (Dia) and Gas Pricing” executed on December 1, 2025, with 263.67 million For votes from 3,015 addresses, the largest governance turnout among recent protocol-level changes.

• ArbOS 51 (Dia) activation passed governance on December 1, 2025, with 263.67 million For votes.
• The August 18, 2025, Constitutional vote removed the previous Cost Cap and updated Executives, with 216.62 million For votes from 2,957 addresses.
• Withdrawals from Arbitrum One are initiated by the Outbox contract, with the L1 challenge window enforced before withdrawals settle on Ethereum.
• The August 2025 cost-cap removal and December 2025 gas-pricing reset together define the post-2025 Arbitrum fee surface; articles citing pre-August 2025 fee numbers are out of date.

What is the average transaction fee on Arbitrum?

Arbitrum transaction fees vary by call complexity and L1 calldata cost, with the December 2025 ArbOS 51 (Dia) upgrade replacing the earlier cost-cap formula. The chain’s headline value proposition remains transaction costs orders of magnitude below Ethereum mainnet; specific fees depend on the operation, the L1 gas environment, and protocol routing. The ArbOS 51 (Dia) activation and gas pricing change executed on December 1, 2025, with 263.67 million ARB for votes, which is the figure that dates older fee estimates.

Arbitrum Architecture and Security Statistics

Arbitrum One is an Optimistic Rollup running the Orbit stack, with the BoLD proof system replacing the earlier permissioned validator set during 2024-2025 upgrades. The chain’s challenge mechanism uses the L1Timelock with a 17-day 8-hour cancellation delay, the longest of any major Ethereum rollup and the architectural source of Arbitrum’s “additional trust assumptions” flag on L2Beat.

• Arbitrum One uses the Orbit stack for its execution layer.
• The L1Timelock enforces a 17-day 8-hour delay on canceling queued transactions through the UpgradeExecutor.
• The L2Timelock operates with an 8-day delay before forwarding actions to the Outbox.
• The Outbox enforces a 6-day 8-hour delay before L2-to-L1 messages finalize, including withdrawals.
• Arbitrum One uses 3 Sequencer EOAs that can submit transaction batches or commitments to the SequencerInbox contract on Ethereum.
• Proposers create new assertions (state commitments), and Challengers submit fraud proofs; both roles are called Validators in the Orbit stack.
• The 17-day 8-hour L1 challenge window is conservative by 2026 standards. Base runs a shorter window via the OPFP proof system. This trade-off explains why L2Beat keeps Arbitrum’s 48.5% trust-flag higher than Base’s 38.2%.

Is Arbitrum a Layer 2?

Yes. Arbitrum One is a Layer-2 Optimistic Rollup on Ethereum, periodically posting state commitments to the Ethereum mainnet and using the BoLD fraud-proof mechanism within the L1 challenge window. Arbitrum operates as an Optimistic Rollup with the Orbit stack and posts data and state commitments back to Ethereum, making it a Layer-2 by L2Beat’s classification.

Arbitrum Ecosystem and Bridged-Asset Distribution

Where Arbitrum holds value matters as much as how much. The TVS breakdown shows roughly half of value flowing through external bridges, the highest external share among the top-3 rollups and the headline counterparty-risk variable for the chain. External bridges hold $7.56 billion of Arbitrum’s $15.57 billion TVS, with canonical bridges holding $3.27 billion and native mints $4.73 billion.

• External bridges account for $7.56 billion of Arbitrum One TVS, the largest single category.
• Canonically bridged assets account for $3.27 billion of Arbitrum One TVS.
• Natively minted tokens account for $4.73 billion of Arbitrum One TVS.
• External bridges represent approximately 48.6% of Arbitrum One TVS.
• Natively minted tokens represent approximately 30.4% of Arbitrum One TVS.
• Canonically bridged assets represent approximately 21.0% of Arbitrum One TVS.

Why it matters: Approximately 48.6% of Arbitrum One’s TVS flows through external bridges, a material share of the chain’s secured value versus Base’s smaller canonical-Native concentration at $2.49 billion canonical and $4.98 billion natively minted. The external-bridge mix exposes the chain to third-party bridge solvency in a way TVS alone doesn’t reveal.

Arbitrum Orbit and Custom L3 Chains

The Orbit stack lets teams deploy Arbitrum-derived chains, with the architecture inheriting the BoLD proof system and the Sequencer / Validator role split that anchors Arbitrum One. In the Orbit stack, both Proposers (creating state commitments) and Challengers (submitting fraud proofs) are classified as Validators, and Orbit chains can settle to Arbitrum One or directly to Ethereum.

• Orbit is the stack name used by Arbitrum One and its derived chains.
• Proposers create new assertions (state commitments) in the Orbit stack.
• Challengers submit fraud proofs in the Orbit stack, with both Proposer and Challenger roles classified as Validators.
• The Orbit stack’s role unification reduces operational complexity for chain deployers; the same multisig pattern covers both honest proposal and challenge response, which lowers the bar for new L3 deployment versus the older Nitro split.

ARB Token Trading and Exchange Listings

ARB has deep crypto exchange liquidity across both centralized venues and Arbitrum-native DEXs, with the ARB/USDT pair as the most active. The most active trading pair, ARB/USDT, has a trading volume of $3,533,550 in the last 24 hours, alongside the crypto exchange market share breakdown that shows how venue dominance maps to L2 governance-token flow.

• ARB/USDT aggregate 24-hour trading volume reached $3,533,550 per the CoinGecko summary.
• CoinGecko lists ARB/USDT as the most active trading pair for the ARB token.
• The ARB 24-hour price range ran from $0.1185 to $0.1222 on the snapshot.
• Cross-venue ARB liquidity sits primarily in the ARB/USDT pair, with self-custody routes via MetaMask wallet data handling residual flow plus the Arbitrum-native DEX route.

Arbitrum Security Council and Risk Statistics

Arbitrum’s Security Council is a 12-member body split into two chambers with rotating elections, the most recent completed in the May 2026 window. The Arbitrum Security Council Election was completed on Tally during the recent governance window, maintaining the multisig threshold that backs emergency protocol response.

• The Security Council Election completed in the most recent governance window indexed by Tally.
• Tally indexes the Security Council Election as a completed governance event.
• The Sequencer role is filled by 3 EOAs that can submit batches to the SequencerInbox contract on Ethereum.
• The Security Council’s election cadence and the 3-EOA Sequencer set together define Arbitrum’s centralization profile; both have been progressively narrowed since the 2023 launch, but neither matches the validity-rollup decentralization story competitors push.

Common Questions

Who controls Arbitrum’s governance?

Arbitrum’s governance is controlled by ARB token holders through the Arbitrum DAO, with proposals indexed on Tally and split between the Arbitrum Core track (protocol-level changes) and the Arbitrum Treasury track (capital allocation). ARB has a 10 billion ERC20 supply backing votes, and recent proposals drew turnout between 674 and 3,015 addresses, with the Security Council providing emergency authority alongside the regular voter base.

How does Arbitrum’s TVS compare to PayPal’s payment scale?

Arbitrum’s L2 settlement layer and centralized payment networks measure different things, but the contrast is instructive. PayPal processes billions in monthly payment volume while Arbitrum secures roughly $15.57 billion in L2-resident assets that can be deployed instantly in any compatible smart contract. Arbitrum One holds $15.57 billion in L2Beat-tracked total value secured, a different financial primitive than the PayPal-style payment rail.

Conclusion

Arbitrum One’s $15.57 billion total value secured anchors the chain at #1 among Ethereum L2 rollups, with Base at $12.11 billion gaining ground and OP Mainnet at $1.57 billion now a distant #3. The ARB token shows a 0.62 Mkt Cap/FDV ratio with 6.15 billion tokens circulating of a 10 billion max supply, while the December 2025 ArbOS 51 (Dia) governance vote and the August 2025 cost-cap removal define current fee economics.

The next inflection point sits at the intersection of three forces: Base’s UOPS-led activity catch-up, the post-ArbOS 51 fee surface, and the Security Council’s ongoing decentralization through Election 5 and beyond. Single-chain coverage will miss the dispersion; the L2 leaderboard with proof-system context and the TVS source-of-funds breakdown surface what aggregate stats hide.
