What is the Arbitrum (ARB) token?

Arbitrum is an optimistic-rollup Layer-2 scaling network for Ethereum, built by Offchain Labs and governed by the Arbitrum Foundation and Arbitrum DAO. Arbitrum batches transactions off-chain and settles fraud-proof commitments to Ethereum L1, cutting fees and latency while inheriting Ethereum's security guarantees. ARB is the network's native governance token, used to vote on DAO treasury allocation and protocol upgrades across Arbitrum One and Arbitrum Nova. Arbitrum's ecosystem spans DeFi, gaming, and modular-blockchain infrastructure.

How does Arbitrum's Layer-2 rollup technology work?

Arbitrum executes transactions off-chain in batches, then posts compressed transaction data and fraud proofs to Ethereum L1 for final settlement. This optimistic-rollup design assumes transactions are valid by default, giving challengers a dispute window to submit fraud proofs before finality. Arbitrum runs two live networks — Arbitrum One and Arbitrum Nova — both settling to Ethereum. This architecture lets Arbitrum offer lower fees than Ethereum mainnet while relying on Ethereum's validator set for security, rather than a separate consensus mechanism.

What is ARB's total supply, and does Arbitrum carry an inflation risk?

Per DropsTab data, ARB's total and max supply are both 10,000,000,000 tokens, fully pre-minted at Arbitrum's TGE. This 10 billion figure is not an immutable hard cap: Arbitrum Foundation governance documentation allows the Arbitrum DAO to mint up to 2% of supply per year via a constitutional proposal vote, with the first eligible mint date March 15, 2024. This creates an inflation-risk factor for ARB holders beyond scheduled vesting unlocks — supply expansion requires DAO approval but is not structurally prevented.

How does Arbitrum's vesting schedule affect ARB investors?

Arbitrum's Investors (17.53%) and Team & Advisors (26.94%) allocations carried a roughly one-year cliff after the March 23, 2023 TGE, with the first large tranche unlocking March 16, 2024 — a combined 10.76% of total supply released in a single day, a notable historical sell-pressure event. From April 2024 through March 16, 2027, both buckets release monthly tranches under a 76-unlock schedule tracked by DropsTab. This structure creates recurring monthly sell-pressure risk from insiders and early backers through early 2027.

Who backed Arbitrum, and what does the fundraising signal?

Arbitrum's parent company Offchain Labs raised a combined $123.7M across three disclosed rounds: a $3.7M Seed round in April 2019, a $20M Series A in April 2021, and a $100M Series B in August 2021 — both later rounds led by Lightspeed Venture Partners at a $1.2B pre-money valuation. Backers include Pantera Capital, Polychain Capital, Mark Cuban, Alameda Research, and Uniswap. Investors collectively hold 17.53% of total ARB supply, spread across many funds with no single-investor concentration disclosed above 20%.

What did Arbitrum's DRIP airdrop require to qualify?

Arbitrum's DRIP (DeFi Renaissance Incentive Program) Season One rewarded users for borrowing against eligible yield-bearing ETH and stablecoin assets on Arbitrum One, distributing a 24,000,000 ARB reward pool. The campaign ran from September 3, 2025 through January 20, 2026 and has since ended. Unlike Arbitrum's original 2023 genesis airdrop, which rewarded historical usage retroactively, DRIP required active participation during the campaign window — users had to open and maintain qualifying leverage-looping borrow positions to earn rewards, per Arbitrum's official program documentation.

How is ARB traded across centralized and decentralized exchanges?

ARB trades on more than a dozen centralized exchanges tracked by DropsTab, including Binance, Coinbase, OKX, Bybit, and Kraken, with pairs primarily against USDT, USDC, USD, and EUR alongside several fiat pairs. This DropsTab dataset covers centralized spot venues only — ARB also trades on Arbitrum-native and Ethereum decentralized exchanges, which fall outside this count. The breadth of major-CEX listings keeps ARB's centralized liquidity risk low, though DEX volume adds a separate liquidity layer this data does not capture.

Is ARB a coin or a token?

ARB is a token, not a coin — Arbitrum runs on Ethereum and Arbitrum One infrastructure rather than powering its own independent Layer-1 consensus mechanism. Arbitrum's contracts are deployed at 0xb50721bcf8d664c30412cfbc6cf7a15145234ad1 on Ethereum and 0x912ce59144191c1204e64559fe8253a0e49e6548 on Arbitrum One. ARB functions specifically as a governance token, giving holders voting rights over Arbitrum DAO treasury allocation and protocol upgrades, distinct from ETH, which pays gas fees on Arbitrum's underlying settlement layer.
