The Arbitrum DAO governs Arbitrum, a leading Ethereum Layer-2 ecosystem built on optimistic-rollup technology. It comprises Arbitrum One (a full rollup), Arbitrum Nova (an AnyTrust chain for gaming and social apps), and the Orbit / Arbitrum Chains framework for launching further chains. Arbitrum One is routinely the single largest rollup by value secured, tracked live on L2Beat. Holders of the ARB token, and the delegates they choose, govern the chains, the treasury, and an elected Security Council. (Arbitrum docs: a gentle introduction)

ARB and the transition to a DAO

Arbitrum was built by Offchain Labs, the company founded in 2018 by Ed Felten, Steven Goldfeder, and Harry Kalodner. On 23 March 2023 the ARB token launched via a broad airdrop, handing governance to the newly-formed Arbitrum DAO. Of an initial supply of roughly 10 billion ARB, the largest single share — about 42.78% — was allocated to the DAO treasury, with the remainder split across the team, investors, the user airdrop, and the Arbitrum Foundation. (Arbitrum Foundation: airdrop distribution)

AIP-1 — the launch controversy

The DAO's very first proposal became one of the industry's cautionary tales. Posted on 15 March 2023, AIP-1 was an omnibus package that, among many other things, designated 750 million ARB (7.5% of supply, then worth roughly $1 billion) to a Foundation-controlled "Administrative Budget Wallet." Delegates discovered that the tokens had already been moved — and that the Foundation had already loaned 40M ARB to a market maker and converted more to fiat — before the vote concluded, which the Foundation framed as a "ratification" of decisions already made rather than a request. The community rejected AIP-1 decisively (over three-quarters of votes against), and the Foundation split it into AIP-1.1 (placing 700M ARB under a four-year lockup and setting a transparent operating budget) and AIP-1.2 (which, among other changes, lowered the on-chain proposal threshold from 5,000,000 to 1,000,000 ARB and affirmed the DAO's power to replace Foundation directors). It remains a landmark case study in the gap between a DAO's launch messaging and its actual power. (CoinDesk; AIP-1.1; AIP-1.2)

Governance structure

Arbitrum governance runs under the Constitution of the Arbitrum DAO, which sorts proposals into two tracks: Constitutional AIPs (amending the Constitution, installing or modifying chain software, or exercising chain-owner powers) and Non-Constitutional AIPs (treasury spends, grants, and signaling). A proposal typically begins with an off-chain Snapshot temperature check, then moves to a binding on-chain vote through the Governor contracts — the Core governor for Constitutional matters (higher quorum) and the Treasury governor for the rest — with the interface hosted on Tally. A 12-member Security Council, split into two six-seat cohorts elected by the DAO every six months, can take emergency and non-emergency actions but only with a 9-of-12 supermajority; ordinary treasury and chain actions clear multi-day timelocks before they execute. (Arbitrum Constitution; Security Council)

Treasury and incentive programs

Holding billions of ARB, the DAO runs one of the largest treasuries in the industry — its dollar value swings heavily with the ARB price, so live figures are best read from DeepDAO or Tally rather than a fixed number. Much of the DAO's activity has been deploying that treasury as ecosystem incentives: the Short-Term Incentive Program (STIP) distributed 50M ARB to protocols in late 2023, followed by a ~21M ARB backfund; the Long-Term Incentive Pilot Program (LTIPP) allocated up to 45M ARB in 2024; the Gaming Catalyst Program (GCP) earmarked 200M ARB for game development; and the DRIP DeFi program and STEP real-world-asset allocations followed in 2025. The scale of these programs — and debates over whether spending outruns revenue — has made treasury discipline the DAO's central governance theme. (STIP proposal; DRIP)

Foundation and Offchain Labs

Two entities sit alongside the DAO. Offchain Labs is the private company that builds the Arbitrum technology; the Arbitrum Foundation is a Cayman Islands foundation that administers governance, handles legal and regulatory matters, and executes DAO decisions — and is itself accountable to the DAO, which can elect and remove its directors. The Foundation received 7.5% of ARB at genesis and contracts with Offchain Labs for core development; the closeness of these "Arbitrum-aligned entities" is a recurring subject of governance scrutiny.

How Caper approaches this

AIP-1 is the cautionary tale a caper is built to avoid: a foundation moved and spent treasury funds before the ratifying vote had concluded. A caper has no administrative wallet that can pre-spend its treasury — funds leave only through a PAYOUT or INVEST proposal that passes the vote and clears an execution delay — and any member who disagrees with where the treasury is heading can exit for their pro-rata share rather than depend on a governance fight to claw funds back. The mechanics are described neutrally on those Caper pages.
